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.
