Mission & purpose

The National Audit Office (NAO) is the UK’s independent public spending watchdog. We support Parliament in holding government to account and we help improve public services through our high-quality audits. We scrutinise public spending for Parliament and are independent of government and the civil service. We help Parliament hold government to account and we use our insights to help people who manage and govern public bodies improve public services. The Comptroller and Auditor General (C&AG), Gareth Davies, is an Officer of the House of Commons and leads the NAO. We audit the financial accounts of departments and other public bodies. We also examine and report on the value for money of how public money has been spent.
