Expand London Market Insurance Portfolio 


HAMILTON, Bermuda, September 3  /PRNewswire-FirstCall/ -- Aspen Insurance
Holdings Limited (NYSE:AHL)(BSX:AHLBSX:BH) ("Aspen") today announces its
intention that Aspen Insurance UK Limited, a wholly owned subsidiary, is to
further expand its London market insurance portfolio by recruiting a new team
to develop an aviation insurance account from 2005.

Aspen continues to develop a more balanced insurance / reinsurance portfolio
with a high quality earnings stream by expanding its insurance underwriting.
Under the leadership of Nick Bonnar, who is responsible for Aspen's London
Market Specialty lines, Aspen's aviation team will join the recently recruited
marine underwriting team, headed by liability specialist John Henderson.

London is the global center for large-risk aviation insurance. We are
recruiting a team with a strong underwriting track record and a reputation for
excellent levels of service that will match Aspen's philosophy."
