The Auditor General is the statutory external auditor of most of the Welsh public sector. This means that he audits the accounts of county and county borough councils, police, fire and rescue authorities, national parks and community councils, as well as the Welsh Government, its sponsored and related public bodies, the Senedd Commission and National Health Service bodies.

The Auditor General’s role includes examining how public bodies manage and spend public money, including how they achieve value in the delivery of public services. The Auditor General publishes reports on that work, some of which are considered by the Welsh Parliament’s Public Accounts Committee.  He also reports every year on how well individual local authorities are planning for improvement.

The Office of Auditor General for Wales was created in 2005 and the current incumbent, Adrian Crompton, has been in the post since 21 July 2018. The post can be held by an individual for a maximum of eight years.
