The National Audit Office (NAO) works on behalf of Parliament and the taxpayer to hold government to account for the use of public money and to help public services improve performance. The relationship with Parliament is central to the roles of the Comptroller and Auditor General (C&AG) and NAO.

We look to place our skills at the service of Parliament as a whole, supporting the Public Accounts Committee (PAC), other select committees from both Houses and individual Members in their scrutiny of public expenditure and service delivery.

Our work

The C&AG is a statutory Officer of the House of Commons and the results of our work are presented to Parliament by Order of the House of Commons.

Our reports

We published over 60 major reports to Parliament and audited some 430 accounts to Parliament in 2013/14. We also provided 20 Select Committees with a wide range of support in addition to our core work for PAC. Our latest Select Committee reports include:
