Governance and accountability

The Audit and Assurance Board (AAB) consists of a non-executive Chair, Police and Crime Commissioners (PCCs), non-executive members and a representative from the Chief Police Staff Officers Association (CPOSA).

The AAB seeks to assure that NPCC business is conducted in accordance with the law and proper standards, in an open and transparent way; that public money is safeguarded and properly accounted for and that resources are managed in an effective, efficient and economical way in achieving the NPCC objectives. The Board also provides scrutiny and approval of NPCC business operations including business plans, risk management, budgets and proposals for capital assets or liabilities.

A performance sub-committee made up of five elected chief officers and two non-executive members holds the NPCC Chair to account on ethical standards, conduct, integrity and performance.
