PRESS RELEASE


      ASPEN INSURANCE HOLDINGS DISCLOSES ESTIMATED IMPACT ON THIRD QUARTER
                EARNINGS FROM FLORIDA STORMS AND TYPHOON SONGDA

HAMILTON, BERMUDA, OCTOBER 13, 2004 -- Aspen Insurance Holdings Limited (NYSE:
AHL; BSX: AHL BH) today announced that, based on anticipated total industry
losses from hurricanes Charley, Frances, Ivan and Jeanne of at least $30
billion, its estimated losses from the hurricanes will have a negative impact on
its third quarter earnings of approximately $135 million, net of reinsurance and
tax. Additionally, the Company estimates that losses from Typhoon Songda could
reduce its third quarter earnings by $13 million, net of reinsurance and tax.

Aspen has received relatively few formal claims advices from clients,
particularly in the cases of Ivan and Jeanne. The estimates are therefore based
on the Company's view of total industry losses and an extensive review of its
clients' exposures. There remains, however, a significant level of uncertainty
and as a result, the actual impact on the Company from these storms could differ
materially from the stated estimates.

Chris O'Kane, Chief Executive Officer, commented: "Due to the rapid succession
and overlapping footprint of the Florida storms, loss adjustment issues are
complicating the claims process and delaying the reporting of claims at the
reinsurance level. Nevertheless, we believe that industry losses of this
magnitude are likely to have a significant impact on trading conditions leading
to increases in price and improvement in terms and conditions for wind exposed
property business in the US."

APPLICATION OF THE SAFE HARBOR OF THE PRIVATE SECURITIES LITIGATION REFORM ACT
OF 1995:

This press release contains forward-looking statements about the effect of
claims resulting from storms in the third quarter on the Company's results of
operations and financial position and their impact on pricing and terms and
conditions. These statements are subject to the Private Securities Litigation
Reform Act of 1995 and are based on management's current estimates, assumptions
and projections. Actual results may differ materially from those projected in
the forward-looking statements for a variety of reasons. Among other things,
these forward-looking statements could be affected by the total industry losses
resulting from these storms, the actual number of the Company's insureds
incurring losses from these storms, the limited actual loss reports received
from the Company's insureds to date, the Company's reliance on industry loss
estimates and those generated by modeling techniques, the amount and timing of
losses actually incurred and reported by insureds to the Company, the
preliminary nature of the range of loss estimates to date from the insurance
industry, the limited ability of claims personnel of insureds to make
inspections and assess claims of losses to date, the inherent uncertainties of
establishing estimates and reserves for losses and loss adjustment expenses, the
impact of these storms on the Company's reinsurers,, the amount and timing of
reinsurance recoverables and reimbursements actually received by the Company
from its reinsurers and the overall level of competition, and the related demand
and supply dynamics, in the wind exposed property reinsurance lines as contracts
come up for renewal.

These and other events that could cause the Company's actual results to differ
are discussed in detail in "Risk Factors" contained in Item 1 of the Company's
Annual Report on Form 10-K for the year ended December 31, 2003 filed with the
Securities and Exchange Commission. We undertake no obligation to publicly
correct or update any forward-looking statements.
