About the National Audit Office

The National Audit Office (NAO) is the UK s main public sector audit body. Independent of government, we have responsibility for auditing the accounts of various public sector bodies, examining the propriety of government spending, assessing risks to financial control and accountability, and reviewing the economy, efficiency and effectiveness of programmes, projects and activities. We report directly to Parliament, through the Committee of Public Accounts of the House of Commons which uses our reports as the basis of its own investigations. We employ around 1,000 staff, most of whom are qualified accountants, trainees or technicians. They work in either of our two service lines, financial audit or value for money (VFM) audit or within the corporate enabling group.
The NAO welcomes applications from everyone. We value diversity in all its forms and the difference it makes to our organisation. By removing barriers and creating an inclusive culture all our people have the opportunity to develop and maximise their full potential. As members of the Business Disability Forum and the Disability Confident Scheme we guarantee to interview all disabled applicants who meet the minimum criteria.

The NAO supports flexible working and is happy to discuss this with you at application stage.
