About us

Our people provide objective insight so that central government can achieve better outcomes and value for money for the public – better insights, better outcomes.


Our role

The Government Internal Audit Agency (GIAA) is an executive agency of His Majesty’s Treasury (HM Treasury). We established our organisation in April 2015 to improve the quality of internal audit provided to central government.

Working across government, our unparalleled access, our expertise and the relationships we build lead to better insights and better outcomes for our customers, and for their customers, and for the UK public. As the government’s primary provider of internal audit services, we lead both the government internal audit profession and internal audit function.

Our internal audit function now covers 75% of central government. This includes 13 departments and over 120 arm’s length bodies (ALBs). The latest list of our Internal Audit customers can be found here: https://www.gov.uk/government/publications/giaa-customer-list-2020-21. Our auditors provide central government with objective, independent insight and assurance enabling its organisations to achieve better outcomes with public money. Through rigorous evaluation and assessment, we help to develop better governance, risk management and internal controls.

We also have an award-winning counter fraud and investigation service, and support finance professionals across government in their role as stewards of public money.

Both our internal audit and counter fraud roles relate to activities requested by, and agreed with, our customer organisations.
