Half Year Results 2018/19

for the period ended 30 September 2018

Delivering for customers, communities and shareholders

Chris Loughlin, Pennon Chief Executive said:

"Momentum for Pennon continues with a strong performance in the first half of 2018/19 across both water and waste. We are delivering on our promises to customers and communities and our investment across the Group is driving tangible and positive results.

In water, we demonstrated our service resilience in extreme weather conditions, with the aftermath of the exceptional cold weather in March followed by the hottest summer on record. Our focus on customers has been reflected in South West Water's best ever customer service score for this half year. With a relentless focus on efficiency and cost savings, average bills are lower than they were 9 years ago, with a further 11% decrease expected in the next regulatory period 2020-2025 under our new business plan. Customers will be empowered as part of a New Deal giving them a tangible stake and say in South West Water.

The focus for Viridor is UK recycling and residual waste processing and transformation. Waste market dynamics are favourable, with the 'Blue Planet' effect spurring action, and we are optimistic that positive changes will be announced in the Government's Resources & Waste Strategy later this year enabling a UK recycling system fit for the future. The operating fleet of Energy Recovery Facilities (ERFs) is performing well, transforming waste into electricity and heat. Progress continues bringing Viridor's remaining four ERFs in the portfolio on stream, with three now in operational ramp up and the final facility under construction. We have further consolidated our position through increasing our holding in one of our joint venture ERFs, Runcorn I. The development of Viridor's ERF portfolio will support Pennon's earnings growth to 2020 and beyond".

About Pennon Group

Pennon is one of the largest environmental infrastructure FTSE 250 groups in the UK with assets of around GBP6.2 billion and a workforce of around 5,000 people. Around 63% of Pennon's shareholders are UK pensions, savings, charities, individuals and employees, with two thirds of South West Water's employees being shareholders.

The integrated water company of South West Water and Bournemouth Water provides water and wastewater services to a population of c.1.7 million in Cornwall, Devon and parts of Dorset and Somerset and water only services to c.0.5 million in parts of Dorset, Hampshire and Wiltshire.

Since 1989 South West Water has invested around GBP7 billion to improve water and wastewater services. This investment means that we will supply some of the best quality drinking water in the UK and have achieved record bathing water quality in recent years.

South West Water was awarded enhanced status for its 2015-2020 Business Plan, and has the highest potential returns in the water sector to 2020.

Viridor is a leading UK recycling and residual waste processing and transformation business providing services to more than 150 local authorities and major corporate clients as well as over 32,000 customers across the UK.

Pennon Water Services provides water and wastewater retail services to over 160,000 non-household customer accounts across Great Britain, and is an 80:20 venture with South Staffordshire Plc.

10 year sector-leading dividend policy

Pennon's purpose is bringing resources to life. We aim to protect the environment, provide an outstanding service to customers and communities, while creating value for our shareholders. Pennon is investing significantly in its UK water and waste infrastructure and estimates capital expenditure of c.GBP1.7 billion between 2015 and 2020, with GBP1.3 billion invested to date. The Group generates robust operating cash flows, and has a strong liquidity and balance sheet position, underpinning a well established sector leading dividend policy.

South West Water has delivered further benefits for customers through our innovative WaterShare mechanism with around GBP100 million of benefits achieved since 2015. Customers will continue to benefit from reinvestment in services and lower bills into the next period.

Whilst delivering on our promises to customers and communities for investors Pennon's long established 10 year dividend policy of 4% year-on-year growth above RPI inflation to 2020 results in an expected doubling of dividend over 10 years (2010-2020)([14]) . This policy reflects the Board's confidence in our sustainable strategy and is underpinned by the highest potential Return on Regulated Equity in the water sector over K6 (2015-2020) and the growth in earnings being delivered by Viridor's ERFs.

For H1 2018/19, the Board has recommended an interim dividend of 12.84p, up 7.3%. The interim dividend will be paid on 4 April 2019 to shareholders on the register on 25 January 2019.

Pennon now offers shareholders the opportunity to invest their dividend in a Dividend Reinvestment Plan (DRIP).

PENNON BUSINESS REVIEW

We know that inspiring trust and delivering transparency are fundamental to our strong relationship with customers and communities. Our vision and core values: 'Trusted, Collaborative, Responsible, Progressive' emphasise to employees and external stakeholders that we strive to be a trusted and responsible Company delivering high quality resilient services in a safe, reliable and sustainable manner. As a UK-listed Company, Pennon has a transparent corporate structure. Our Board is focused on strong financial control, sound administration and good governance.

Delivering on our promises for customers and communities

We know that delivering a resilient service in South West Water is a key promise to our customers. Despite the periods of extreme weather during 2018 with the 'freeze and thaw' in March and the hot dry summer, giving rise to unprecedented demand, we continued to deliver an excellent service to our customers. This has been reflected in our best ever quality service score in H1 2018/19, with South West Water ranked 2(nd) out of all water and sewerage companies in England and Wales.

South West Water has delivered further benefits for customers through our innovative WaterShare mechanism with around GBP100 million of benefits achieved since 2015. Customers will continue to benefit from reinvestment in services and lower bills into the next period.

Viridor continues to expand the ERF portfolio with three new facilities Glasgow, Beddington and Dunbar all processing waste with operations due to ramp up over the next 18 months. We continue to work closely with our key customers and partners across our whole portfolio to deliver service in line with expectations.

Delivering strong sustainable financial performance across the Group

Confidence in our financial resilience is driven by robust operating cash flows, a strong liquidity and balance sheet position and a diversified mix of low cost and flexible funding which underpins a sector leading dividend policy.

Pennon through its operating businesses performed well in H1 2018/19 and is on track to be in line with management expectations for 2018/19.

Earnings growth for 2018/19 has been driven by ERF portfolio growth, weather related higher revenue in South West Water, and a strong focus on cost savings, benefitting both customers and shareholders.

The cost savings and synergy targets of c.GBP17 million p.a. from 2019, identified through our targeted overhead review in 2015/16, are on track with c.GBP15 million p.a. delivered to date.

South West Water continues to deliver sector leading Totex outperformance and is on track to deliver c.GBP300 million over the 2015-2020 regulatory period. Together with delivery of net ODI rewards and outperformance in our cost of financing, momentum of delivery has been maintained with a cumulative Return on Regulated Equity (RORE) of 11.8%[15] to H1 2018/19.

The build out of the ERF portfolio is supporting growth in Viridor and the recycling activities have recovered from the challenging position in H2 2017/18. Viridor has continued to focus on cost savings with initiatives delivering indirect cost efficiencies of 17% in real terms since 2015/16.

Balanced business plan for 2020-2025

In September South West Water submitted its business plan for 2020-2025 (K7). As a responsible and transparent water business a fundamental part of our proposals is for a New Deal which signals a new way of doing business for our customers and stakeholders. This approach is focused on empowering our customers by giving them the option of a tangible financial stake and a share in the business and the power to hold us to account, with a say in our business through a Customer AGM.

The initial assessment of the business plan by Ofwat is expected at the end of January 2019. Given customer acceptance of our plan was at 88% preparations are already underway for a fast start in K7, with key supply chain delivery partnerships in place, pilot trials for new water treatment technology completed and preparatory work for taking on the expanded licence area of the Isles of Scilly is in progress.

Leading, responsible and sustainable UK waste operator

Viridor is focused on delivering UK recycling and residual waste processing and transformation. We believe there are continued favourable waste market dynamics in both recycling and residual waste.

Whilst the recycling market has been challenging, Viridor has delivered improvements to its recycling performance in H1 2018/19 compared with H2 2017/18, with EBITDA increasing from GBP4.4 million to GBP7.4 million. With Government support for recycling and the UK Plastics Pact outlining a roadmap with targets to 2025 we believe there are opportunities for growth. The 'Blue Planet' effect continues to encourage action and we expect positive changes to be announced in the Government's Resources & Waste Strategy when published.

We continue to expect UK residual waste market dynamics to be favourable with demand for ERFs exceeding capacity into the long term. We anticipate the capacity gap to be greater than seven million tonnes (mT) by 2030. Household waste arisings have increased annually since 2012 and expenditure on waste services is up c.16%[16] from 2008/09. The operational ERF portfolio is on track to achieve availability in excess of 90%[17] in 2018/19 with the operational performance of the facilities above management's initial base case expectations which assume a real post tax IRR (internal rate of return) of 8%. EBITDA margin in H1 2018/19 was 60%. Three of the four remaining ERFs are processing waste with operational ramp up over the next 18 months. Construction is progressing well at Avonmouth near Bristol.

We see further opportunities to deliver capacity expansion at existing facilities, having secured planning permissions and permits for additional capacity at Cardiff (75,000 tonnes) and Ardley (27,000 tonnes), as well as an increase in power output at Runcorn II.

We have further consolidated our position through increasing our holding in Viridor's joint venture (TPSCo)[18], which owns Runcorn I ERF, from 37.5% to 75.0% of the economic interest.

We believe our landfill portfolio complements the combustible residual waste strategy, with a requirement for a landfill solution into the medium term.

We also continue to consider further expansion and investment, with development of energy park opportunities across the landfill and ERF portfolio capitalising on the potential of existing grid connections.

Pennon continues to seek and identify further growth opportunities within the UK, assessing the long-term viability of the markets in which we operate and achieving an appropriate risk/reward balance and is confident of delivering sustainable, long-term returns from water and waste.

Non-underlying Items

There is one non-underlying item in H1 2018/19 which arises as a result of the movement in the fair value of long-dated derivatives associated with South West Water's 2040 bond. This results in a charge of GBP8.9 million (H1 2017/18 charge of GBP7.8 million). The tax impact of this non-underlying item is a credit of GBP1.7 million, resulting in an after tax position of GBP7.2 million.

In the prior period, the net charge before tax for H1 2017/18 was GBP1.3 million and included a GBP6.5 million credit as a result of the reset of the Greater Manchester contracts as well as the GBP7.8 million charge for the movement in the fair value of long-dated derivatives associated with South West Water's 2040 bond. Net non-underlying items after tax for the prior period resulted in a GBP3.0 million credit.

Strong Group underlying financial performance

Group revenue in H1 2018/19 increased by 3.1% (GBP22.8 million) to GBP746.7 million.

Revenue from South West Water increased by 3.2% (GBP9.3 million) to GBP301.5 million due to customer demand increases of 2.7%, from the hot and dry weather over the summer, tariff increases of 1.0% and increased infrastructure connections. Viridor revenues increased by 3.8% (GBP15.3 million) to GBP422.3 million primarily due to the ERF build out (net of reduced construction IFRIC 12 revenue).

Group EBITDA and adjusted EBITDA were ahead of the same period last year by 8.1% and 3.1% respectively, with South West Water, Viridor and Pennon Water Services all ahead of H1 2017/18. The gap between EBITDA and adjusted EBITDA narrowed in the period as expected due to reduced share of JV EBITDA following the reset of the Greater Manchester waste contract in 2017/18.

South West Water's EBITDA and operating profit increased by 4.1% and 4.0% respectively. Strong cost management and efficiency delivery has resulted in lower than inflation cost increases, despite the increased costs required to meet higher customer demand of c.GBP3 million in H1 2018/19. In addition, South West Water's bad debt performance remains strong with a charge of 0.6% of revenues (H1 2017/18 0.9%) reduced from 1.7% at March 2015. This continues to be driven by efficient collections as we work with our customers to manage their debt and strive to support those customers in vulnerable circumstances with affordability challenges.

Viridor's EBITDA for the first half of 2018/19 increased by 17.7% (GBP11.8 million) compared with H1 2017/18.

The ERF business has performed strongly during the period, in line with expectations. The EBITDA generated from our portfolio was 28.8% higher at GBP66.6 million (H1 2017/18 GBP51.7million) reflecting financial contributions from Beddington and Dunbar. We are on track to deliver another year of availability for our current operational assets in excess of 90%[31] across the portfolio (including Joint Ventures). As we continue to optimise our performance, more of our planned maintenance outages have been completed in the first half of this financial year, when electricity demand and pricing is lower. Planned maintenance has been performed at all major sites during the half year and as a result availability during H1 2018/19 was 89%.

Landfill EBITDA has increased by 15.2% to GBP3.8 million since H1 2017/18 (GBP3.3 million). Volumes and pricing have held up, with cost savings contributing to the higher EBITDA. We continue to see demand for a landfill solution into the medium term, and have sites well positioned to meet these demands, with 11 sites operational for H1 2018/19. As part of the planned closure profile, one site (Rigmuir) closed in September leaving 10 operational sites.

In our landfill gas business we are currently progressing our engine replacement strategy, including investing in maintenance and more efficient engines. This is improving reliability and securing generation for the longer term, whilst optimising the generating capacity potential at our sites. EBITDA for the period at GBP8.1 million, is down 12.0% from the prior year (H1 2017/18 GBP9.2 million). This has been driven by higher planned maintenance activities during the summer period to secure reliable generation during the winter and a natural decline in gas volumes produced from sites (although at 4% this is at a lower rate than previous years). The benefit of higher year on year hedged electricity prices has helped support the overall performance.

Recycling EBITDA at GBP7.4 million is GBP3.0 million higher than H2 2017/18, with EBITDA margin increasing by GBP5 per tonne to GBP12 per tonne reflecting some recovery in the global recycling markets following import restrictions by China in H2 2017/18. EBITDA is GBP3.2 million lower than the first half of last year (H1 2017/18 GBP10.6 million) which was before the Chinese restrictions were implemented, consequently EBITDA margin per tonne has decreased from GBP14 (H1 2017/18) to GBP12 (H1 2018/19). Market led quality demands have remained challenging, and we have continued to face challenges with poor input quality. We have continued to focus on producing high quality outputs which has contributed to an increase in revenue per tonne to GBP110 (H2 2017/18 GBP97; H1 2017/18 GBP97). We have seen an overall reduction in recyclate volumes sold, higher waste output and an increase in costs of production. Our focus continues to be on the production of higher quality recyclates as well as adopting 'self-help' measures to create margin improvement. To help mitigate our exposure to recyclate price volatility we continue to share commodity risks and rewards with our customers.

In the period Contracts, Collections and Other EBITDA was broadly comparable with the prior period at GBP20.3 million (H1 2017/18 GBP20.0 million). Following last year's reset, the Greater Manchester run off contract financial results are in line with our expectations. In November 2018 Viridor withdrew from the Greater Manchester waste operating contract tender process and we expect the run-off contract to cease in early 2019/20. The financial impact of not continuing with this operational contract is not material to the Group, and our position with the ERFs at Runcorn is unaffected.

Viridor's indirect costs have continued to fall, marginally down this period to GBP27.8 million from GBP28.2 million in H1 2017/18, and are 17% lower in real terms than 2015/16.

Joint venture EBITDA has reduced from GBP25.4 million in H1 2017/18 to GBP13.4 million. This is a result of the contract reset at Greater Manchester in September last year. This saw both the disposal of our Viridor Laing joint venture and the introduction of a lower contractual EBITDA for our TPSCo joint venture following the repayment of external debt as part of the reset. Interest savings mean that TPSCo profit after tax was not significantly impacted by the reset. TPSCo continues to deliver strong operational and financial performance.

Planned maintenance profiling in H1 2018/19 at our Lakeside joint venture has resulted in financial performance slightly below last year, however, underlying operational and financial performance has remained strong, again exceeding our original expectations, for both waste processing and power generation.

IFRIC 12 interest receivable at GBP7.3 million is broadly comparable with H1 2017/18 of GBP6.9 million.

Pennon Water Services has continued to successfully gain new customers during its second year of trading. Overall EBITDA for the first half is GBP0.9 million (H1 2017/18 GBP0.5 million), with a focus on improving operating cost efficiencies.

Group efficiencies achieved as a result of the Shared Services initiatives have delivered a further GBP2 million of cost savings and synergy benefits during the first half of the year bringing the cumulative position to c.GBP15 million p.a. to date, and we are on track for the cumulative c.GBP17 million p.a. targeted from 2019.

Net Finance Costs

Underlying net finance costs of GBP40.8 million are GBP4.2 million higher than last half year (H1 2017/18 GBP36.6 million). This is attributable to higher net debt from continuing capital investments and lower interest receivable on shareholder loans following the Greater Manchester contract reset.

We have secured funding at a cost that is efficient and effective with the effective interest rate reducing marginally to 3.6% (H1 2017/18 3.7%), remaining sector leading.

The effective interest rate is calculated after adjusting for capitalised interest of GBP8.3 million, notional interest items totalling GBP6.3 million, interest received from shareholder loans to joint ventures of GBP2.5 million and IFRIC 12 interest receivable of GBP7.3 million. The effective interest rate for South West Water in the period was 3.5% (H1 2017/18 3.5%).

During H1 2018/19 underlying net finance costs (excluding pensions net interest costs of GBP0.9 million, discount unwind of provisions of GBP5.4 million and IFRIC 12 notional interest receivable of GBP7.3 million) were GBP52.6 million, covered 4.3 times by Group operating profit (H1 2017/18 GBP51.1 million and 4.3 times).

Profit before tax

Group underlying profit before tax was GBP142.5 million, an increase of 8.7%, compared with the prior half year (H1 2017/18 GBP131.1 million). Included in profit before tax is our share of joint venture profit after tax of GBP4.8 million (H1 2017/18 GBP5.3 million). On a statutory basis, profit before tax was GBP133.6 million (H1 2017/18 GBP129.8 million) reflecting a non-underlying charge before tax of GBP8.9 million (H1 2017/18 GBP1.3 million).

Taxation

The Group's underlying mainstream UK corporation current tax charge for the half year (before prior year adjustments) was GBP15.6 million, reflective of an effective tax rate of 10.9% (H1 2017/18 GBP14.3 million, 10.9%). The lower effective rate versus the UK's mainstream corporation tax rate of 19% reflects the accelerated level of capital allowance claims available to the Group compared to the Group depreciation charge. There was a prior year credit of GBP3.2 million recognised for the period (H1 2017/18 credit of GBP4.3 million), the credits reflect the resolution of minor outstanding tax items with HMRC.

Underlying deferred tax for the period (before prior year adjustments) was a charge of GBP12.2 million (2017/18 H1 charge GBP10.2 million). The charge for H1 2017/18 primarily reflects capital allowances across the Group in excess of depreciation charged. There was a prior year deferred tax credit of GBP5.3 million recognised for the period (H1 2017/18 GBP1.6 million charge), reflecting finalisation of capital allowance claims.

In addition, in H1 2018/19 there is a non-underlying GBP1.7 million current year deferred tax credit (2017/18 H1 GBP1.3 million deferred tax credit) relating to the non-underlying movement in the fair value of long-dated derivatives associated with South West Water's 2040 bond. There was also a GBP3.0 million non-underlying current tax credit in H1 2017/18 (relating to the reset of the Greater Manchester Contract); there is no current tax effect of the non-underlying items in H1 2018/19.

Overall the total tax charge for the period was GBP17.6 million (H1 2017/18 GBP17.5 million).

Earnings per share

Earnings per share on both a statutory and underlying basis before deferred tax has been positively impacted by a reduction in hybrid costs[32] period on period in addition to increased profits. As a consequence earnings per share on both a statutory and underlying basis has increased by 17.4% at 25.6p (H1 2017/18 21.8p) and 18.6% at 30.0p (H1 2017/18 25.3p) respectively.

Robust cash inflow from operations, continuing investment in future growth

The Group's operational cash inflows in H1 2018/19 were GBP266.6 million[33] (H1 2017/18 GBP308.9 million). These funds have been put to use in efficiently financing the Group's capital structure and investing in future growth. This investment has resulted in higher Group net debt.

Contributions into the Group's pension schemes for the half year were GBP8.5 million, and corporation tax payments were GBP12.2 million. Included in other movements of GBP48.0 million is the 2017 unwind settlement of the PMB derivative. Total tax payments reflecting all taxes borne by the Group in H1 2018/19 were GBP63.4 million[34] (H1 2017/18 GBP59.0 million).

Sustainable funding position underpinning investment

The Group has a strong liquidity and funding position with GBP1,056 million cash and committed facilities at 30 September 2018. This consists of cash and deposits of GBP406 million (including GBP186 million of restricted funds representing deposits with lessors against lease obligations) and undrawn facilities of GBP650 million. At 30 September 2018 the Group's borrowings totalled GBP3,448 million.

Pennon has pioneered a sustainable financing framework to integrate commitments to environmental and social objectives into a variety of funding opportunities across the Group. The framework allows Pennon to access future funding opportunities aligned with the green loan principles, green bond principles and social bond principles. The framework has been certified by DNV GL a leading sustainability verifier. Pennon is committed to continuous annual improvements in sustainability ratings and KPIs which may lead to improved interest rate margins.

During the period, GBP480 million of new and renewed facilities have been signed, GBP340 million in Pennon Group plc and GBP140 million in South West Water. In total, GBP350 million of the new facilities signed in the half year are linked to the sustainable nature of the business. Included in these facilities is an inaugural Pennon Group loan from the EIB[35].

Pennon has cash and committed facilities for the remainder of South West Water's planned K6 capital programme and our ERF investments. Further funding will be sourced over K6 to:

-- Maintain an appropriate headroom of cash and committed facilities, including replacing maturing finance

-- Prepare for the next regulatory period.

Efficient long-term financing strategy

The Group has a diversified funding mix of fixed (GBP1,771 million, 58%), floating (GBP708 million, 23%) and index-linked borrowings (GBP563 million[36], 19%). The Group's debt has a maturity of up to 39 years with a weighted average maturity of c.20 years. Much of the Group's debt is floating rate and derivatives are used to fix the rate on that debt. The Group has fixed, or put swaps in place to fix, the interest rate on a substantial portion of the existing water business debt for the entire K6 period, in line with the Group's policy for this regulatory period to have at least 50% of funding fixed.

South West Water's cost of finance is amongst the lowest in the industry. Around two thirds of South West Water's net debt is from finance leases which provide a long maturity profile. Interest payable benefits from the fixed credit margins which are secured at the inception of each lease. GBP563 million (c.25%) of South West Water's debt is index-linked at an overall real rate under 2.0%. This represents a quarter of the net funding for South West Water, a level below Ofwat's notional level of 33%, which we believe gives an advantageous position given the RPI to CPIH transition.

Following the submission of the South West Water business plan the Group is looking to align the hedging for the next regulatory period with the changed regulatory methodology. A proportion of new debt will be hedged in K7 on a rolling ten year basis whilst still maintaining flexibility within the overall portfolio. Embedded debt hedging will be aligned with the regulatory delivery period.

Net debt position

In the first half of 2018/19 the Group's net debt increased by GBP240 million to GBP3,042 million. Cash inflow from operations was GBP267 million. Cash outflows relating to the capital programme totalled GBP192 million[37], slightly reduced as expected from the peak years of the Group's capital expenditure in 2016/17 and 2017/18. The gearing ratio at 30 September 2018, being the ratio of net debt to (equity plus net debt) was 65.5% (31 March 2018 63.1%, 30 September 2017 64.8%) and is expected to reduce by the year end.

The combined South West Water and Bournemouth Water debt to RCV ratio is 62.1%[38] (31 March 2018 60.3%, 30 September 2017 62.1%) which broadly aligns with Ofwat's K6 target for efficient gearing of 62.5%.

Group net debt includes GBP2,125 million for South West Water with the remaining GBP917 million supporting investment in Viridor growth and expansion including the amount invested in joint ventures, through shareholder loans of GBP41 million for TPSCo and Lakeside.

Capital investment focused on regulatory expenditure and ERF build out

Group capital investment was GBP201 million[39] in H1 2018/19 compared with GBP222 million(39) in H1 2017/18.

Viridor

Viridor's capital spend(39) in the period was GBP131.9 million (H1 2017/18 GBP124.3 million), an increase of GBP7.6 million over H1 2017/18.

The majority of capital investment continues to relate to the delivery of the ERF fleet[40], with GBP103 million of total spend relating to the three ERFs in operational ramp up and Avonmouth under construction. Our ERFs at Glasgow, Beddington and Dunbar are all processing waste.

Other capital expenditure included lifecycle capital expenditure on our operational ERF fleet and development of our Clyde Valley ERF fuel supply facility. On-going restoration and remediation programmes continue for our landfill assets, ensuring we meet or exceed our environmental duties and responsibilities.

South West Water

South West Water's capital expenditure in the first half of the year was GBP68.6 million, compared with GBP97.6 million in H1 2017/18 with the profile aligned with the K6 capital plan reflecting the completion of specific large investment programmes at Mayflower Water Treatment Works and the bathing and shellfish water improvements.

Key areas of drinking water investment and activity during H1 2018/19 included:

-- Completion of the new state-of-the-art Mayflower water treatment works which has entered commissioning, with c.GBP6 million of expenditure in H1 2018/19 (H1 2017/18 c.GBP19 million)

-- Investment in our infrastructure to reduce the number of bursts and leakage impacted by the 'freeze and thaw' in March 2018 and costs associated with the hot dry summer (c.GBP6 million).

Key areas of wastewater investment and activity during H1 2018/19 included:

   --    Finalisation and completion of the Plymouth bathing water scheme 
   --    Continued improvements at wastewater treatment works including flood resilience 
   --    Investment for growth in order to meet increases in supply and demand. 

Pensions

The Group operates defined benefit pension schemes for certain employees of Pennon Group. The main schemes were closed to new entrants on or before 1 April 2008.

At 30 September 2018 the Group's pension schemes showed an aggregate deficit (before deferred tax) of GBP44.8 million (March 2018 GBP49.5 million), a reduction of GBP4.7 million. Pension liabilities decreased by GBP3.8 million mainly due to higher corporate bond yields, while asset values increased marginally by GBP0.9 million.

The net aggregate liabilities of GBP37 million (after deferred tax) represented around 1% of the Group's market capitalisation at 30 September 2018.

Energy hedging

Pennon has adopted a group portfolio management approach to energy hedging, and has the ability to hedge its market position for periods up to five years ahead, further helping to protect revenues.

Forward hedges have been put in place in the liquid market with the Group c.80% hedged until March 2020 and c.55% hedged until 2021 for its energy (generation net of internal usage of electricity). In addition, the Group has a natural hedging opportunity which represents one third of Viridor's energy generation, as South West Water is a net user of electricity.

The energy portfolio management team continues to actively manage the Group net energy generation position in liquid markets.

SOUTH WEST WATER

OPERATIONAL PERFORMANCE

Delivering a resilient service for customers - excellent management of operational challenges

Despite the challenges of extreme weather, South West Water has continued to deliver a resilient service to its customers. During the exceptional cold weather[41] in March, with the first red weather warning for snow in the South West, our proactive planning and management ensured we were able to manage the impacts of the 'freeze and thaw' effectively. We have also supported customers with leak repair activity and focused on fixing visible leaks within two days.

Alongside this increased activity we have maintained supplies to customers despite the unprecedented demand over the hot dry summer. This has been the hottest summer on record and water through our network has increased c.6.0% from last year. This increased demand has been further challenged with the significant increase in visitors to the region over the summer period (c.20% increase). Despite this, 2018 has been our 22(nd) year without water restrictions and supply interruptions have reduced this period. In addition, we have supported the Isles of Scilly over the summer months to maintain supplies in that area when water levels fell to extreme lows.

Customers at the heart of our delivery

Improving customer service is at the heart of our delivery plans. South West Water achieved its best ever quality service score in H1 2018/19, ranked 2(nd) out of all water and sewerage companies in England and Wales. Our customer service score (SIM) increased again and is now expected to be above average for the industry this year, with no penalty forecast for the K6 period. The SIM score is calculated against a qualitative element (based on a customer survey) and a quantitative element that takes into account, amongst other things, the number of complaints received in writing or by phone, which continue to fall.

The improvement in service is driven by a range of activities including enhanced 'customer journeys', which have been developed jointly with customers, increasing customer resolution as well as improving the channels with which customers can contact us, such as online and social media.

South West Water has been leading the way for the last 10 years in providing support to customers who find themselves in vulnerable circumstances or who struggle to pay their bills. We have continued to focus on this and are targeting to eliminate water poverty in our 2020-2025 Business Plan. Preparation for these additional activities is already underway and those currently receiving support through reduced tariffs has increased to c.23,000 customers, the highest proportion in the industry[42], and over 55,000 customers are supported through other programmes.

Since the opening of the non-household retail market in April 2017, South West Water has operated successfully with 19 different retailers and our wholesale service desk has been operating effectively.

Maintaining momentum - continued sector leading outperformance

South West Water has performed well in H1 2018/19, and has delivered in line with management expectations. Strong operational and financial performance underpins our sector leading RORE[43], which has been consistently above 11%[44] annually and remains 11.8% cumulatively since the start of the K6 business plan period. Of the 11.8%, 6.0% is the base return, 2.6%[45] reflects Totex savings and efficiencies, 0.3% reflects a net reward on Outcome Delivery Incentives (ODIs) and 2.9%[46] reflects the difference between actual and assumed financing costs using a cumulative forecast RPI over K6 of 2.8%, which is consistent with the approach adopted for calculating our innovative WaterShare mechanism. Cumulatively the WaterShare RORE outperformance over K6 is consistent with the approach adopted by Ofwat.

 
                                 H1 2018/19[47]   K6 to date

Totex efficiency reducing customer bills

South West Water is striving for ever greater efficiency. Totex outperformance has already achieved cumulative savings of GBP209 million[48] to H1 2018/19 and we are on track to deliver c.GBP300 million of Totex savings by 2020, which are embedded into our 2020-2025 business plan.

These savings are being driven by:

-- Managing upward cost pressures, with actual net price rises being below annual average inflation rates

-- Continuing advantages from our strategic alliances and driving efficiency from our procurement processes

-- Reducing customer debt through enhanced collections activities and increasing our affordability schemes (such as social tariffs), with the cost of bad debt now below the level assumed within the 2014 Final Determination

-- Efficiencies from the Bournemouth Water integration, including delivery of key capital schemes in the region, with c.GBP19 million of net synergies delivered to date

-- Ensuring efficient capital investment through the use of data analytics, optimising capital and operating solutions and promoting efficient off-site build techniques.

This focus on cost efficiency is reducing bills for customers, and our 2020-2025 business plan continues to target cost efficiency, supporting an 11% real reduction in customer bills by 2025.

ODIs continue to deliver net reward

Operational performance for the half-year based on delivery by 30 September 2018 resulted in a net ODI reward of GBP1.2 million[49] (GBP9.3 million cumulatively for K6) reflecting RORE outperformance of 0.2%[50], a slight reduction from last year. Good asset reliability with stable serviceability across all water and wastewater areas has been maintained. Rewards were delivered across bathing water quality and water restrictions, as well as significant improvements in external and internal sewer flooding, which continue to deliver rewards. The cumulative net reward of GBP9.3 million to H1 2018/19 comprises GBP15.4 million of total rewards and GBP6.1 million of total penalties. ODI penalties which apply within the regulatory period will reduce customer bills as they are 'passed back'. ODI net penalties of GBP2.1 million have been adjusted in customer bills for 2018/19 and GBP0.3 million will be adjusted in the 2019/20 tariffs.

Whilst the overall net value of ODI reward has fallen in 2018/19, this is a result of the profile of ODI rewards over the current regulatory period. South West Water is forecasting to meet all its ODI commitments this year with a number of areas moving out of penalty.

   --    Pollution incidents 

Pollution incidents in the year have continued to fall, with only one significant pollution incident in the calendar year so far. This would result in zero penalties for the year (compared to the cumulative penalty of GBP3.6 million).

   --    Flooding 

Continuing the strong performance in 2017/18, the number of flooding incidents in H1 2018/19 has reduced and based on this performance is expected to result in further rewards this year.

   --    22(nd) consecutive year without water restrictions 

Despite the unprecedented increase in customer demand over the hot dry summer, water resources in the South West Water region remained unrestricted for a twenty-second consecutive year and the Bournemouth water region maintained its position of having no water restrictions since privatisation. As the weather continues to remain drier than usual South West Water is actively managing our water resources and may implement storage schemes to protect future supplies.

   --    Bathing water quality - c.99% achieving sufficient quality, over 78% excellent 

Our legacy of major investment to protect bathing waters continues to be reflected in extremely positive results for the 2018 bathing water season. Of the 151 bathing waters tested in the South West Water region, 149 (c.99%) were classified 'sufficient' or better, with more than 78% classified as 'excellent'. Neither of the two bathing waters rated as 'poor' were attributed to any failure of South West Water's assets.

   --    Leakage 

The impact of the 'freeze and thaw' in March 2018 has seen leakage levels increase along with the number of bursts in the region. South West Water is targeting investment and operational resources to meet our leakage target of 84 megalitres per day in 2018.

   --    Supply interruptions - meeting targets 

Demand over the summer months placed pressure on both our treatment works and network to meet customer demand. Despite this the average duration of supply interruptions per property for South West Water remains on track to meet the target for the year based on performance in H1 2018/19.

Financing investment efficiently

Alongside strong operational outperformance, South West Water is confident that the efficient and effective financing strategy in place will continue to deliver cumulative K6 financing outperformance, with GBP115 million delivered in the K6 period to date. Since the year end a GBP60 million lease has been agreed under the Pennon sustainable financing framework, specifically linked to the new innovative Mayflower water treatment works. Gearing levels remain aligned with Ofwat's current notional level and South West Water is the only UK water company to share the benefits of lower interest rates with customers.

Sharing outperformance between customers and shareholders

South West Water is sharing the benefits of business outperformance between customers and shareholders through our unique WaterShare mechanism. Since 2015 c.GBP100 million of cumulative benefits([51]) have been identified to share with customers through investment in services and lower future bills. This reflects GBP71 million of Totex savings, GBP9 million of net ODI benefits and GBP16 million of other benefits (including financing). These Totex savings and efficiencies (including the forecast to 2020) have been reflected in the 2020-2025 business plan, lowering bills for customers over the next regulatory period. The other savings identified in recent years and expected out to 2020 will provide the basis for delivering the New Deal for customers.

New Deal 2020-2025 - delivery preparations underway

Empowering customers through a New Deal

The key focus for our 2020-2025 business plan is empowering customers through a New Deal. It will ensure customers are sharing in our success and having a say through a Customer AGM, which will allow customers to hold us directly to account. In addition, the option for customers to have a shareholding gives them a tangible stake in our business through the outperformance delivered and will further ensure customers are at the heart of our business.

The business plan proposes new benchmarks for service and efficiency, with a key target being to eliminate water poverty by 2025.

Delivery preparations underway

The next regulatory period includes specific comparative service and environmental targets which will be measured consistently across the whole industry every year. Based on existing performance South West Water is already delivering above average performance in 10 ODIs[52].

A successful part of our delivery has been our commitment to strong partnerships. For the next regulatory period we have already put in place a number of key partnerships, including our capital investment partners who will transition to our capital alliance H5O. In addition we have secured a number of other partners including universities, housing associations, customer advocates and environmental charities.

South West Water has also focused on preparing for operational excellence and early planning of our investment programme. This includes pilot trials of new water treatment technology in Bournemouth and supporting the Isles of Scilly operations over the summer months with preparatory work for take-over already in progress.

VIRIDOR

Confident outlook for Viridor in the waste sector

Viridor is focused on UK recycling and residual waste processing and transformation.

Recycling

The Government's Resource & Waste Strategy is expected to confirm the fundamentals of the waste market and provide a stimulus to recycling. The 'Blue Planet' effect continues to drive Government action and there are potential opportunities arising from Brexit which also require consideration.

The UK Plastics Pact (a unique pact between governments, businesses, local authorities, NGOs and citizens) is seeking to transform the UK's plastics system. The pact has targets including:

   --    100% of plastic packaging to be reusable or recyclable 
   --    70% of plastic packaging effectively recycled (from current 43%) 
   --    Problematic or unnecessary single-use plastics eliminated 
   --    30% average recycled content across all plastic packaging. 

EPR & PRN[53] reform is also recommended by the National Audit Office and is expected to improve the returns from investments in recycling, a key factor being standardised collections increasing household waste quality.

Viridor's 2018 Recycling Index Report shows that over 80% of the public is worried about plastics in the oceans, and over 60% of consumers were more likely to buy products with packaging made from recycled materials.

Residual waste activities (ERFs and Landfill)

The market fundamentals for ERFs remain strong, with the gap between combustible residual waste arisings and ERF capacity forecast to remain over 7 million tonnes (mT) per annum to 2030. In addition the Autumn Budget noted that 'the Government recognises the important role incineration currently plays in waste management in the UK...'.

The Viridor portfolio processes a fifth of the UK ERF combustible waste tonnage and continues to optimise its assets through capacity expansions, heat transfer and offtake opportunities.

Viridor recognises that the landfill portfolio complements its residual waste strategy. We continue to foresee a requirement for a landfill solution into the medium term. As landfill sites close over the coming years, parts of the country will experience a shortage of capacity. Viridor's landfill sites are well positioned to support future market requirements. Available void on operating sites is c.30 million cubic metres, equivalent to c.15 years overall capacity at current run rates, with 5 sites having capacity to 2030 and beyond.

Strong operational focus

ERFs continuing to perform strongly

Our ERFs have delivered strong operational performance in the first half of 2018/19.

We are on track to deliver another year of availability in excess of 90% across our operational portfolio (including joint ventures). As we continue to optimise our performance, more of our planned maintenance outages have been completed in the first half of the financial year, when electricity demand and pricing is lower. Planned maintenance has been performed at all major sites during the half year. Cumulatively to date maintenance is running at c.2.1% of capital expenditure. This is expected to increase over the life of the assets with an underlying future average rate of c.3.5%.

Glasgow, Beddington and Dunbar are all processing waste. Optimisation is ongoing and operations will ramp up over the next 18 months, as has previously occurred at the other ERFs in our portfolio.

As previously reported, completion of construction of our Glasgow Recycling and Renewable Energy Centre has required a higher level of remediation and expenditure than predicted. This has been driven by the high level of non-conformances that have required rectification for work performed by our previous Engineering, Procurement and Construction (EPC) contractor. Viridor is contractually entitled to recover incremental costs from the original principal contractor, Interserve, under certain circumstances. Discussions with Interserve are ongoing with regard to the contractual settlement. The gross receivable is GBP72 million, after taking into account an assessment of market indicators of credit risk for the EPC contractor, a provision of GBP8 million has been recognised resulting in a net receivable of GBP64 million at 30 September 2018.

Construction work progresses at Avonmouth and is on track for takeover in line with the planned costs and timetable. Processing equipment is now being erected within the structural steel frame.

With the new facilities burning waste, our operational design capacity has increased to 2.9 million tonnes of waste and 242 megawatts (MW) per annum, including joint ventures. This will extend to 3.2 million tonnes of waste and 276 MW by 2021.

Responding to recycling markets

Following the impact that import restrictions imposed by China had on global recycling markets in H2 2017/18, we have seen some recovery in H1 2018/19. Paper prices have improved from their low point, and pricing on other commodities are slightly ahead of last year.

We have continued to focus on producing higher quality recyclates to fulfil market demands and revenue per tonne has increased 13.4% to GBP110 (H1 2017/18 GBP97, H2 2017/18 GBP97). This increase in quality requirement has resulted in increased costs of production and a reduction in volumes being produced.

We remain confident that our recycling business is on track for full year results in line with our expectations.

We have made good progress with our FMCG[55] customers in the period in developing 'closed-loop' solutions, providing high quality recycled plastics and polymers. Utilising innovative technology and processes we are creating value from the requirement for recycled materials, to replace virgin material in premium consumer packaging.

Landfill portfolio complements residual waste strategy

Viridor continued to operate 11 landfill sites in H1 2018/19, with one site at Rigmuir (Glasgow) closed in September as part of the planned closure profile leaving 10 operational sites. Consented landfill capacity reduced from 40.5 million cubic metres (mcm) to 30 mcm in the 6 months to September 2018, reflecting usage during the period and the closure of Rigmuir. We have a track record of effectively restoring our sites and repurposing these for alternative uses with 3 closed landfill sites repurposed for development in recent years.

Landfill volumes and average gate fees are comparable with H1 last year at 0.9 million tonnes and GBP22 per tonne. Our landfill energy business continues to be managed to maximise the value of landfill gas power generation. We continue to explore alternative commercial development opportunities and other renewable energy solutions at our landfill sites, such as photovoltaic (PV) and energy storage.

At present, Viridor's landfill gas engines contribute 86MW of landfill gas generation capacity, a decrease from 88MW at March 2018. This reflects the replacement of larger older engines with smaller more efficient engines designed to optimise the gas volumes produced at the sites. Viridor also has a PV capacity of 3.2MW. We currently have surplus grid connection capacity at some sites, which presents an opportunity for growth subject to suitable capital investment. Investment opportunities to create energy parks, including private wire connections to local industry and developments are being assessed.

Average revenue per Megawatt hour (MWh) increased by 7.4% to GBP87 (H1 2017/18 GBP81). Average operating costs increased 23.1% to GBP48 per MWh (H1 2017/18 GBP39) reflecting increased investment in planned preventative maintenance to secure reliable generation, including for the upcoming winter period.

Revenue during the period has increased by 2.8% compared to H1 2017/18, with a 4% reduction in gas volumes in H1 2018/19 being offset by the higher energy prices.

Contracts and Collections

The run-off contract to operate the recycling assets of the Greater Manchester Combined Authority has delivered in line with expectations. In November 2018 Viridor withdrew from the Greater Manchester waste operating contract tender process and we expect the run-off contract to cease in early 2019/20. The financial impact of not continuing with an operational contract is not material to the Group, and our position with the ERFs at Runcorn is unaffected.

Our Contract and Collections business continues to provide a valuable service to all our customers and secures the volume of input materials needed to operate our ERF, landfill and recycling assets.

Joint Ventures continue to perform strongly

The joint venture at Lakeside ERF (a 50:50 joint venture with Grundon Waste Management) has had another strong half year. In its ninth year of operation it continues to outperform its original targets for both waste processing and power generation.

The TPSCo joint venture (between Viridor, John Laing Investments and Inovyn) has also performed strongly during the half year.

In November 2018, Viridor exercised its pre-emption rights and agreed a GBP54.5 million cash consideration to acquire John Laing Investments Limited's 37.5% economic interest and 20% voting rights in the Runcorn I ERF. The acquisition consolidates further Viridor's leading market position in UK Energy Recovery and results in an increase to Pennon's economic interest in INEOS Runcorn (TPS) Holdings Limited from 37.5% to 75.0%, with the associated voting rights moving from 20% to 40%.

PENNON WATER SERVICES

Focus on delivering operating cost efficiencies

Pennon Water Services (PWS), our 80:20 retail venture with South Staffordshire Plc, continues to deliver net customer[56] and revenue growth during its second year of operation, with continued success with the dual service position.

Serving over 160,000 customer accounts across 18 different wholesale regions, Pennon Water Services has c.10,000(56) new customer accounts generating around GBP31 million of new revenue, with 100% new contract renewal rate to date.

We continue to focus on delivering customer service that reflects the needs of our business customers with satisfaction scores increasing in the period. We are now implementing further strategies to improve operating cost efficiency within the competitive market including within billing and cash management.

Board Matters

As previously announced and in line with governance best practice, Martin Angle, Non-Executive Director and chairman of the Remuneration Committee, who has been a Director for nine years, will stand down from the Board on 31 December 2018. Iain Evans has been appointed as his successor and joined the Board in September 2018. We thank Martin for his considerable contribution to the Group's success and strong governance over the years.

PRINCIPAL RISKS AND UNCERTAINTIES

In accordance with DTR4.2.3 and 4.2.7 of the Disclosure & Transparency Rules, the principal risks and the associated residual risk exposure for the remaining six months of the financial year have been reviewed by the Directors and are considered to be unchanged from those reported on pages 55 to 60 of the Annual Report and Accounts 2018. A summary of Pennon Group's principal risks is detailed below.

These principal risks have been reconsidered against a continued back drop of broader macro political and economic uncertainties; including the potential renationalisation of the water industry in the event of a change in Government and ongoing negotiations between the UK and the EU on any withdrawal agreement.

Specifically, the Board has considered the potential implications of a 'no deal' scenario between the UK and the EU on the Group's principal risks, which was informed by guidance documentation issued by the UK Government. Appropriate mitigation strategies have been developed in order to minimise any potential impact on the Group.

The Board considers the principal risks to be:

Law, Regulation and Finance

   --    Changes in Government Policy - renationalisation 
   --    Changes in Government Policy - single use plastics 
   --    Regulatory reform 
   --    Compliance with laws and regulations 
   --    Maintaining sufficient finance and funding to meet ongoing commitments 
   --    Non-compliance or occurrence of avoidable health and safety incidents 
   --    Tax compliance and contribution 
   --    Increase in the defined benefit pension scheme deficit 

Market and Economic Conditions

   --    Non-recovery of customer debt 

-- Macro-economic risks arising from global and UK economic downturn impacting commodity and power prices

Operating Performance

   --    Poor operating performance due to extreme weather or climate change 
   --    Poor customer service and/or increased competition leading to loss of customer base 
   --    Business interruption or significant operational failures/ incidents 

-- Difficulty in recruitment, retention and development of appropriate skills required to deliver the Group's strategy

Business Systems and Capital Investment

   --    Failure or increased cost of capital projects and/or exposure to contract failures 
   --    Failure of information technology systems, management and protection including cyber risks

                          and its subsidiary undertakings have adequate resources to continue 
                          in business for the foreseeable future, and that it is therefore 
                          appropriate to adopt the going concern basis in preparing the 
                          condensed half year financial information. 
 
                         This condensed half year financial information has been reviewed 
                          but not audited by the independent auditor pursuant to the Auditing 
                          Practices Board guidance on the "Review of Interim Financial Information". 
 
                         The preparation of the half year financial information requires 
                          management to make judgements, estimates and assumptions that 
                          affect the application of accounting policies and the reported 
                          amounts of assets and liabilities, income and expense. Actual 
                          results may differ from these estimates. The significant judgements 
                          made by management in applying the Group's accounting policies 
                          and the key sources of estimation uncertainty are consistent with 
                          those that applied to the consolidated financial statements for 
                          the year ended 31 March 2018, with the exception of changes in 
                          estimates that are required in determining the half year provision 
                          of income taxes.

                         Notes to condensed half year financial information (continued) 
               3.        Accounting policies 
 
                         Other than the revised policy on revenue as a result of the application 
                          of IFRS 15, as set out in note 21 below, the accounting policies 
                          adopted in this condensed half year financial information are 
                          consistent with those applied and set out in the Pennon Group 
                          plc Annual Report and Accounts for the year ended 31 March 2018 
                          and are in accordance with all IFRSs and interpretations of the 
                          IFRS Interpretations Committee expected to be applicable for the 
                          year ending 31 March 2019 in issue which have been adopted by 
                          the EU. 
                         The tax charge for September 2018 and September 2017 has been 
                          derived by applying the anticipated effective annual rate to the 
                          first half year profit before tax. 
 
                         New standards or interpretations which were mandatory for the 
                          first time in the year beginning 1 April 2018 did not have a material 
                          impact on the net assets or results of the Group. 
 
                          New standards or interpretations due to be adopted from 1 April 
                          2019, including IFRS 16 'Leases' are not expected to have a material 
                          impact on the Group's net assets or results. Existing borrowing 
                          covenants are not impacted by changes in accounting standards. 
 
                         As disclosed in the Pennon Group plc Annual Report and Accounts 
                          for the year ended 31 March 2018 the Directors anticipate the 
                          adoption of IFRS 16 on 1 April 2019 will affect primarily the 
                          accounting for the Group's operating leases. At 31 March 2018 
                          the Group had non-cancellable operating lease commitments of GBP163 
                          million. These predominantly relate to leases of properties occupied 
                          by the Group in the course of carrying out its businesses. If 
                          the standard had been adopted for the year ended 31 March 2018 
                          it is estimated that this would have resulted in the Group recognising 
                          an asset in use and corresponding lease liability figure in the 
                          region of GBP115 million. This would have resulted in a minimal 
                          impact of profit before tax but an estimated increase of around 
                          GBP7 million to EBITDA which would be replaced by increased charges 
                          for depreciation and finance costs. 
 
                         Initial adoption of IFRS 15 Revenue from Contracts with Customers 
 
                         The Group adopted the standard with effect from 1 April 2018 using 
                          the full retrospective approach to transition. As the impact of 
                          the new standard has not had a material effect on the Group's 
                          reported revenues, net assets or any specific financial statement 
                          line, there has been no restatement of prior year figures. 
 
                         The disaggregation of revenue information required by IFRS 15 
                          is given below within note 4 (Segmental information) for the six 
                          month periods ended 30 September 2018 and 30 September 2017. 
                          The revised accounting policy on revenue following implementation 
                          of IFRS 15 is set out below in note 21. 
 
                         Initial adoption of IFRS 9 Financial Instruments 
 
                         IFRS 9, which applies from 1 April 2018, requires the Group to 
                          evaluate and recognise expected credit losses on financial assets 
                          and to ensure changes in credit risk are assessed at regular intervals, 
                          and to make suitable adjustments for expected credit losses where 
                          applicable. 
 
                         As disclosed within note 4 Critical accounting judgements and 
                          estimates in the Pennon Group Plc Annual Report and Accounts for 
                          the year ended 31 March 2018, at the balance sheet date each subsidiary 
                          evaluates the collectability of trade receivables and records 
                          provisions for doubtful debts based on experience including comparisons 
                          of the relative age of accounts and consideration of actual write-off 
                          history. On adoption of IFRS 9 the evaluation has been extended 
                          to include the forward-looking assessment of expected credit losses 
                          and changes in credit risk. Adoption of the new approach has not 
                          had a material impact on the impairment of trade receivables.

        4.                Segmental information (continued) 
 
 
                          Intra-segment trading between different segments is under normal 
                           market based commercial terms and conditions. Intra-segment 
                           revenue of the other segment is reflected as a cost. 
 
                           Factors such as seasonal weather patterns can affect sales 
                           volumes, income and costs in both the water and waste management 
                           segments. 
 
                          The grouping of revenue streams by how they are affected by 
                           economic factors, as required by IFRS 15, is as follows:

   1                                 Last year, on reset of the contracts associated with the 
                                      Greater Manchester Waste Disposal Authority (GMWDA) an 
                                      overall net credit before tax of GBP6.5m was recognised 
                                      as follows: 
 
                                      (a) A net amount of GBP3.2m was recognised in revenue 
                                      following the settlement of all outstanding claims relating 
                                      to the construction of assets. 
 
                                      (b) On reset of the contracts associated with GMWDA, ownership 
                                      of Viridor Laing Holdings Limited passed to the GMWDA. 
                                      On transfer GBP23.5m of Viridor's shareholder loans were 
                                      repaid, resulting in the write down of the remaining financial 
                                      asset of GBP19.2m. 
 
                                      (c) On reset of the contracts associated with GMWDA repayment 
                                      of external bank debt in our joint venture, INEOS Runcorn 
                                      TPSCo Limited, was financed by GMWDA. This change in cash 
                                      flows resulted in the recognition of income in this joint 
                                      venture, with an amount deferred relating to a lower ongoing 
                                      gate fee. The overall share of profit after tax in the 
                                      half year related to the reset was GBP22.5m, which contributed 
                                      to an increase in investments in joint ventures recognised 
                                      on the balance sheet to GBP23.0m (31 March 2017 GBP0.1m). 
 
   2                                 In the period a charge of GBP8.9m was recognised relating 
                                      to non-cash derivative fair value movements associated 
                                      with derivatives that are not designated as being party 
                                      to an accounting hedge relationship (H1 2017/18 GBP7.8m). 
                                      These movements are non-underlying due to the nature of 
                                      the item being market dependant and potentially can be 
                                      significant in value (size).

          UK corporation tax is calculated at 19% (H1 2017/18 19%) of 
           the estimated assessable profit for the year. The tax charge 
           for September 2018 and September 2017 has been derived by applying 
           the anticipated effective annual tax rate to the first half 
           year profit before tax. 
 
          Tax on amounts included in the consolidated statement of comprehensive 
           income, or directly in equity, is included in those statements 
           respectively. 
 
          The effective tax rate for the period before the impact of non-underlying 
           items was 14% (H1 2017/18 17%). 
 
            The effective tax rate for the period including the impact of 
            non-underlying items was 13% (H1 2017/18 13%).

 8.       Earnings per share 
 
          Basic earnings per share are calculated by dividing the earnings 
           attributable to ordinary shareholders by the weighted average 
           number of ordinary shares outstanding during the period, excluding 
           those held in the employee share trust which are treated as 
           cancelled. For diluted earnings per share, the weighted average 
           number of ordinary shares in issue is adjusted to include all 
           dilutive potential ordinary shares. 
 
          The weighted average number of shares and earnings used in the 
           calculations were:

          Adjusted basic and diluted earnings per ordinary share 
 
          Adjusted earnings per share are presented to provide a more 
           useful comparison on business trends and performance. Non-underlying 
           items are adjusted for by virtue of their size, nature or incidence 
           to enable a full understanding of the Group's financial performance 
           (as described in note 5). Perpetual capital returns are proportionately 
           adjusted to allow a more useful comparison in the period. Earnings 
           per share have been calculated as follows:

          On 22 September 2017 the Company issued GBP300m perpetual capital 
           securities. Costs directly associated with the issue of GBP3.3m 
           were set off against the value of the issuance. They have no 
           fixed redemption date but the Company can at its sole discretion 
           redeem all, but not part, of these securities at their principal 
           amount on 22 May 2020 or any subsequent periodic return payment 
           date after this. 
 
          The Company has the option to defer periodic returns on any 
           relevant payment date, as long as a dividend on the Ordinary 
           Shares has not been paid or declared in the previous 12 months. 
           Deferred periodic returns shall be satisfied only on redemption 
           or payment of dividend on Ordinary Shares, all of which only 
           occur at the sole discretion of the Company. 
 
          As the Company paid a dividend on 4 April 2018 the periodic 
           return of GBP8.6m, scheduled 22 May 2019, is payable and consequently 
           has been recognised as a liability at 30 September 2018.

               Valuation hierarchy of financial instruments carried at fair value 
 
               The Group uses the following hierarchy for determining the fair 
                value of financial instruments by valuation technique: 
 
 
                      *    quoted prices (unadjusted) in active markets for 
                           identical assets or liabilities (level 1) 
 
 
                      *    inputs other than quoted prices included within level 
                           1 that are observable for the asset or liability, 
                           either directly (that is, as prices) or indirectly 
                           (that is, derived from prices) (level 2). 
 
               The fair value of financial instruments not traded in an active 
                market (level 2, for example over-the-counter derivatives) is 
                determined by using valuation techniques. A variety of methods 
                and assumptions are used based on market conditions existing at 
                each balance sheet date. Quoted market prices or dealer quotes 
                for similar instruments are used for long term debt. Other techniques, 
                such as estimated discounted cash flows, are used to determine 
                fair value for the remaining financial instruments. The fair value 
                of interest rate swaps is calculated as the present value of the 
                estimated future cash flows. 
 
                The Group's financial instruments are valued principally using 
                 level 2 measures:

                                   The Group establishes provisions in connection with contracts 
                                   and litigation where it has a present legal or constructive 
                                   obligation as a result of past events and where it is more likely 
                                   than not an outflow of resources will be required to settle 
                                   the obligation and the amount can be reliably estimated. 
 
                                   Contingent assets

                                   are further possible recoveries that are contingent on events 
                                   in the future that are not wholly within the Group's control. 
                                   These contingent assets have not been recognised as at 30 September 
                                   2018.

                                  The Group's significant related parties during the period were

                                   and its associate INEOS Runcorn (TPS) Holdings Limited, for which 
                                   disclosures were made in the Pennon Group plc Annual Report and 
                                   Accounts for the year ended 31 March 2018. 
                                  There were no material changes during the half year to September 
                                   2018 in the nature of transactions with these related parties. 
 
 21.                              Accounting policy on revenue recognition 
 
                                  IFRS 15 provides a single, principles based five-step model to 
                                   be applied to all sales contracts. It is based on the transfer 
                                   of control of goods and services to customers and replaces the 
                                   separate models for goods, services and construction contracts 
                                   previously included in IAS 11 Construction Contracts and IAS 
                                   18 Revenue. Under IFRS 15, revenue is recognised at an amount 
                                   that reflects the consideration to which an entity expects to 
                                   be entitled in exchange of fulfilling its performance obligations 
                                   to a customer. 
 
                                  The implementation of the new standard has not had a material 
                                   effect on the Group's reported revenues, net assets or any specific 
                                   financial statement line, but the Group has reviewed and amended 
                                   its accounting policy in line with the concepts and terminology 
                                   used in the standard. The revised policy is as follows: 
 
                                  Revenue recognition 
 
                                  Group revenue is recognised following delivery of performance 
                                   obligations and an assessment of when control over the product 
                                   or service is transferred to the customer. Revenue is only recognised 
                                   when collection of consideration is highly probable. 
 
                                  Revenue is recognised either when the performance obligation 
                                   in the contract has been performed ('point in time' recognition) 
                                   or 'over time' as the performance obligations to the customer 
                                   are satisfied. For each obligation satisfied over time, the Group 
                                   applies a revenue recognition method that accurately reflects 
                                   performance in transferring control of the services to the customer.

 21.                              Accounting Policy on revenue recognition (continued) 
 
                                  Where a contract with a customer includes more than one performance 
                                   obligation revenue is allocated to each obligation in proportion 
                                   to a fair value assessment of the total contract sales value 
                                   split across the services provided. 
 
                                  At the inception of a contract the total transaction price is 
                                   estimated, being the fair value to which the Group expects to 
                                   be entitled under the contract, including any variable consideration. 
                                   Variable consideration is based on the most likely outcome of 
                                   the performance obligations. 
 
                                  Revenue excludes value added tax, trade discounts and revenue 
                                   arising from transactions between Group companies. Revenue includes 
                                   landfill tax. 
 
                                  Water (domestic and non-household retail) 
 
                                  For most of the services provided to domestic customers, contract 
                                   terms are implied through statute and regulation in the absence 
                                   of formal, written contracts. South West Water has a duty under 
                                   legislation to provide domestic customers with services regardless 
                                   of payment and is not permitted to disconnect domestic customers 
                                   for non-payment of bills. Charges are set via the periodic review 
                                   price-setting process, regulated by Ofwat. 
 
                                  In respect of ongoing, continuous services to customers, such 
                                   as the provision of drinking water and waste water services, 
                                   revenue is recognised over time in line with customer usage of 
                                   those services. 
 
                                  Customers with an unmeasured supply are billed at the start of 
                                   the year for the full amount of the annual charge but typically 
                                   take advantage of a choice of payment arrangements to pay by 
                                   regular instalments. 
 
                                  Customers with a metered supply are sent up to four bills per 
                                   year, based either on actual meter readings or estimated usage. 
                                   For these customers, revenue includes an estimation of the amount 
                                   of unbilled usage at the period end. Payment options for domestic 
                                   customers include an annual Meter Payment Plan where customers 
                                   agree to pay a fixed amount per month which is adjusted to reflect 
                                   actual consumption at the end of the year. 
 
                                  A range of regulated services is offered to property developers 
                                   and owners who require connection to the water and sewerage networks 
                                   or need the networks to be extended or altered. Typically, these 
                                   customers pay an estimate of the charges in advance as a deposit, 
                                   which is treated as a contract liability and are billed or refunded 
                                   the difference between the estimate and actual costs on completion 
                                   of the work. 
 
                                  Where the performance obligation relates solely to a connection 
                                   to the network, revenue is recognised at the point of connection 
                                   when the customer is deemed to obtain control. 
 
                                  Where assets are constructed or provided by the Group or assets 
                                   transferred to the Group, it is considered that there is an explicit 
                                   or implied performance obligation to provide an ongoing water 
                                   and / or waste water service, with the result that revenue is 
                                   recognised over a time no longer than the economic life of assets 
                                   provided by or transferred to the Group. 
 
                                  Pennon Water Services provides specialist retail water and waste 
                                   water services to business customers. It raises bills and recognises 
                                   revenue in accordance with its contracts with customers and in 
                                   line with the limits established for the non-household periodic 
                                   price-setting process where applicable.

                                  Energy sales 
 
                                  The Group receives revenue from the sale of electricity from 
                                   generating assets. These assets include solar, anaerobic digestion, 
                                   gas from landfill and Energy Recovery facilities. Revenue from 
                                   the sale of electricity from the Group's generating assets is 
                                   measured based upon metered output delivered at rates specified 
                                   under contract terms or prevailing market rates. Revenue is recognised 
                                   at a 'point in time', being the point of distribution to the 
                                   grid. Typically, invoices are raised monthly with standard payment 
                                   terms. 
 
                                  Waste Management Services 
 
                                  In respect of single services with fixed fees, such as the receipt 
                                   of gate and collection fees, revenue is recognised at the time 
                                   the service is provided. 
 
                                  The Group also delivers other waste management services for which 
                                   revenue is recognised 'over time' in accordance with contracts 
                                   with customers. The nature of contracts and/or performance obligations 
                                   includes management fees to operate local authority recycling 
                                   centres and energy recovery facilities, multi service contracts 
                                   including collections and gate fees. 
 
                                  Revenue from other services can be fixed (i.e. management fees) 
                                   or variable (i.e. gate fees). 
 
                                  Gate fee revenue, derived from the Group's operational assets, 
                                   is recognised as customer waste is deposited and is based on 
                                   tonnage received. 
 
                                  In respect of waste collection services, revenue is recognised 
                                   at the point of collection from customer premises. 
 
                                  A majority of waste management customers are invoiced monthly 
                                   for services provided within the monthly billing period. Payments 
                                   are made on an end of month following invoice basis. Alternative 
                                   billing and/or payment terms are agreed in exceptional circumstances. 
 
                                  The Group transfers control of such waste management services 
                                   prior to invoicing. Receipt of payment following invoice is based 
                                   solely on the passage of time. A trade receivable is recognised 
                                   until payment is made and/or refund issued. 
 
                                  Where the Group has entered into service concession arrangements 
                                   it accounts for these contracts in accordance with IFRIC12. Consideration 
                                   is treated as contract assets or other intangible assets, depending 
                                   upon the right to receive cash from the asset. Consideration 
                                   is split between construction of assets, operation of the service 
                                   and provision of finance recognised as interest receivable. 
 
                                  Revenue in respect of construction services is recognised over 
                                   time and is based on the fair value of work performed, with reference 
                                   to the total sales value and the stage of completion of those 
                                   services, as this best reflects the manner in which control passes 
                                   to the customer. In accordance with IFRIC 12 an amount equal 
                                   to the revenue recognised is split between costs recoverable 
                                   from construction activities disclosed within other intangible 
                                   assets when the concession grantor has not provided a contractual 
                                   guarantee in respect of the recoverable amount regardless of 
                                   the service use by customers, and/or within other non-current 
                                   assets when the concession grantor contractually guarantees the 
                                   payment of amounts determined in the contract or the shortfall, 
                                   if any, between amounts received from users of the public service 
                                   and amounts specified or determined in the contract. No payments 
                                   are received during construction. 
 
                                  In respect of operating services, revenue is recognised over 
                                   time in line with delivery of operational services in accordance 
                                   with the contract with the local authority.

 Notes to the condensed half year financial information (continued) 
 
 21.                              Accounting Policy on revenue recognition (continued) 
 
                                  Once the operational phase commences the Group has a right to 
                                   receive consideration for the construction and operational services 
                                   delivered. Invoicing occurs monthly and payments are due by the 
                                   end of the month following date of invoice. 
 
                                  Recyclate 
 
                                  The Group transforms waste into recyclate ready for resale. Revenue 
                                   is measured at the agreed transaction price per tonne of recyclate 
                                   under the contract with the customer. Revenue recognition occurs 
                                   when control over the recyclate assets has been transferred to 
                                   the customer. 
 
                                  In respect of UK sales, the Group's performance obligation is 
                                   satisfied at the point of collection by the customer. This is 
                                   the point in time when an invoice is issued and revenue is recognised 
                                   Payment terms are typically end of month following invoice date. 
                                   Overseas sales are predominantly agreed under a letter of credit. 
                                   Goods are despatched at the point the letter of credit is accepted 
                                   by the customers bank. Payment is released when the customer 
                                   confirms satisfactory receipt of the recyclate. This is the point 
                                   legal title (i.e. control) passes to the customer and revenue 
                                   is recognised. 
 
 22.                              Post balance sheet events 
 
                                  On 26 October 2018, the High Court of Justice of England and 
                                   Wales issued a judgement in a claim between Lloyds Banking Group 
                                   Pension Trustees Limited (claimant) and Lloyds Bank plc and others 
                                   (defendants) regarding the rights of female members of certain 
                                   pension schemes to equality of treatment in relation to pension 
                                   benefits (GMP equalisation). The judgement concluded that the 
                                   claimant is under a duty to amend the schemes in order to equalise 
                                   benefits for men and women in relation to guaranteed minimum 
                                   pension benefits. 
 
                                  The judgement also provided comments on the method to be adopted 
                                   in order to equalise benefits, on the period during which a member 
                                   can claim in respect of previously underpaid benefits, and on 
                                   what should be done in relation to benefits that have been transferred 
                                   into, and out of, the relevant schemes. The issues determined 
                                   by the judgement arise in relation to many other occupational 
                                   pension schemes. The extent to which the judgement will increase 
                                   the liabilities of the Group's defined benefit pension schemes 
                                   is under consideration. The Group expect to recognise a past 
                                   service cost amount in the income statement in the range of GBP2-4m 
                                   in the second half of 2018/19, following a detailed assessment 
                                   of the GMP equalisation impact. 
 
                                  On 16 November 2018, Viridor Waste Management Limited exercised 
                                   its pre-emption rights to acquire John Laing Investments Limited's 
                                   37.5% economic interest and 20% voting rights in INEOS Runcorn 
                                   (TPS) Holdings Limited for a cash consideration of GBP54.52m, 
                                   following a decision by John Laing to sell its holding in the 
                                   joint venture. 
 
                                  The acquisition will increase Viridor's economic interest in 
                                   INEOS Runcorn (TPS) Holdings from 37.5% to 75%, with the associated 
                                   voting rights moving from 20% to 40%.

                   INDEPENT REVIEW REPORT TO PENNON GROUP PLC 
   Introduction 
 
   We have been engaged by the Company to review the condensed 
   consolidated set of financial statements in the half-yearly 
   financial report for the six months ended 30 September 2018 
   which comprises the Consolidated income statement, the Consolidated 
   statement of comprehensive income, the Consolidated balance 
   sheet, the Consolidated statement of changes in equity, the 
   Consolidated statement of cash flows and related notes. We 
   have read the other information contained in the half yearly 
   financial report and considered whether it contains any apparent 
   misstatements or material inconsistencies with the information 
   in the condensed set of financial statements. 
 
   This report is made solely to the company in accordance with 
    guidance contained in International Standard on Review Engagements 
    2410 (UK and Ireland) "Review of Interim Financial Information 
    Performed by the Independent Auditor of the Entity" issued 
    by the Auditing Practices Board. To the fullest extent permitted 
    by law, we do not accept or assume responsibility to anyone 
    other than the company, for our work, for this report, or for 
    the conclusions we have formed. 
 
   Directors' Responsibilities 
 
   The half-yearly financial report is the responsibility of, 
    and has been approved by, the directors. The directors are 
    responsible for preparing the half-yearly financial report 
    in accordance with the Disclosure and Transparency Rules of 
    the United Kingdom's Financial Conduct Authority. 
 
   As disclosed in note 2, the annual financial statements of 
    the Group are prepared in accordance with IFRSs as adopted 
    by the European Union. The condensed set of financial statements 
    included in this half-yearly financial report has been prepared 
    in accordance with International Accounting Standard 34, "Interim 
    Financial Reporting", as adopted by the European Union. 
 
   Our Responsibility 
 
   Our responsibility is to express to the Company a conclusion 
    on the condensed set of financial statements in the half-yearly 
    financial report based on our review. 
 
   Scope of Review 
 
   We conducted our review in accordance with International Standard 
    on Review Engagements (UK and Ireland) 2410, "Review of Interim 
    Financial Information Performed by the Independent Auditor 
    of the Entity" issued by the Auditing Practices Board for use 
    in the United Kingdom. A review of interim financial information 
    consists of making enquiries, primarily of persons responsible 
    for financial and accounting matters, and applying analytical 
    and other review procedures. A review is substantially less 
    in scope than an audit conducted in accordance with International 
    Standards on Auditing (UK and Ireland) and consequently does 
    not enable us to obtain assurance that we would become aware 
    of all significant matters that might be identified in an audit. 
    Accordingly, we do not express an audit opinion. 
 
   Conclusion 
 
   Based on our review, nothing has come to our attention that 
    causes us to believe that the condensed consolidated set of 
    financial statements in the half-yearly financial report for 
    the six months ended 30 September 2018 is not prepared, in 
    all material respects, in accordance with International Accounting 
    Standard 34 as adopted by the European Union and the Disclosure 
    and Transparency Rules of the United Kingdom's Financial Conduct 
    Authority.
