National Audit Office


The National Audit Office (NAO) scrutinises public spending for Parliament. The scope of our work and influence is vast – supporting Parliament to hold government to account and addressing significant public spending challenges such as the current cost of living crisis, the continuing response to COVID-19 and the climate change emergency.


Our work helps to improve financial management and the way vital public services are delivered to millions of people every day. In 2021, the NAO’s work led to a positive financial impact through reduced costs, improved service delivery or other benefits to citizens of £874 million.
