Independent review report to Aviva plc

Introduction

We have been instructed by the Company to review the financial information for the six months ended 30 June 2005 which comprises the Summarised Consolidated Income Statement – EEV basis, the Summarised Consolidated Statement of Recognised Income and Expense – EEV basis, the Summarised Consolidated Statement of Changes in Equity – EEV basis, the Summarised Consolidated Balance Sheet – EEV basis, the Segmentation of the Summarised Consolidated Balance Sheet – EEV basis, the Information on the EEV basis, the Summarised Consolidated Income Statement – IFRS basis, the Reconciliation of Group Operating Profit to Retained Profit for the Period – IFRS basis, the Summarised Consolidated Balance Sheet – IFRS basis, the Summarised Consolidated Statement of Recognised Income and Expense – IFRS basis, the Summarised Consolidated Statement of Changes in Equity – IFRS basis, the Summarised Consolidated Cash Flow Statement – IFRS basis, the related notes 1 to 16, and First Time Adoption of International Financial Reporting Standards. We have read the other information contained in the interim report and considered whether it contains any apparent misstatements or material inconsistencies with the financial information.

This report is made solely to the Company in accordance with guidance contained in Bulletin 1999/4 “Review of interim financial information” 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 interim report, including the financial information contained therein, is the responsibility of, and has been approved by, the directors. The directors are responsible for preparing the interim report in accordance with the Listing Rules of the Financial Services Authority.

As disclosed in the basis of preparation – IFRS basis note, the next annual financial statements of the Group will be prepared in accordance with those IFRSs adopted for use by the European Union.

The accounting policies are consistent with those that the directors intend to use in the next financial statements. There is, however, a possibility that the directors may determine that some changes to these policies are necessary when preparing the full annual financial statements for the first time in accordance with those IFRSs adopted for use by the European Union. This is because, as disclosed in the basis of preparation – IFRS basis note, the directors have anticipated that revised IAS 19, revised IAS 39 and IFRIC 4, which have yet to be formally adopted for use by the European Union, will be so adopted in time to be applicable to the next annual financial statements.

Review work performed

We conducted our review in accordance with guidance contained in Bulletin 1999/4 “Review of interim financial information” issued by the Auditing Practices Board for use in the United Kingdom. A review consists principally of making enquiries of group management and applying analytical procedures to the financial information and underlying financial data, and based thereon, assessing whether the accounting policies have been applied. A review excludes audit procedures such as tests of controls and verification of assets, liabilities and transactions. It is substantially less in scope than an audit performed in accordance with United Kingdom Auditing Standards and therefore provides a lower level of assurance than an audit. Accordingly we do not express an audit opinion on the financial information.

Review conclusion

On the basis of our review we are not aware of any material modifications that should be made to the financial information as presented for the six months ended 30 June 2005.
