Who We Are

Who we are

We are the UK’s independent public spending watchdog

Our position is unique.  We support Parliament in holding the government to account and we help improve public services through our high-quality audits.


This means we work for, and for the good of all citizens in our country.  Our work is extraordinarily influential and impactful.  We are independent of government and the civil service.

We help our economy and society work better – supporting and enabling improvements in financial management and the way in vital public services are delivered right across the public sector to millions of people every day.  For you, this means challenging and varied work that has real benefit for the nation.

We work across a range of topics that affect public life — from health and social care, welfare, transport, and education, to defence, environmental sustainability, digital infrastructure, and risk and resilience. We also produce insights, overviews, good practice guides and recommendations aimed at helping public organisations improve.

Our mission is founded on independence, integrity, and impact. As a non-ministerial department, we operate impartially, reporting our findings directly to Parliament. We adhere to strict standards in auditing and financial reporting. Our role is not just to identify problems, but to support and encourage improvements in government operations.

Our Impact

Making a Difference Across Government

In 2025, our work delivered £2.6 billion of positive financial impact, equivalent to £24 of value for every £1 spent running the NAO. Our recommendations help government improve financial management, strengthen public services and deliver better outcomes for citizens across the UK.

Our influence extends beyond financial savings. We audit more than 400 government accounts each year, examine how public money is spent, and provide insights that help government organisations work more effectively, manage risk and deliver better value for taxpayers.

As an NAO audit trainee, you’ll contribute to work that has a real impact, helping to improve government and public services while developing a professional qualification and building a rewarding career.
