The Accountancy & Actuarial Discipline Board ("AADB") is the independent, investigative and disciplinary body for accountants and actuaries in the UK. It has up to eleven members.

The AADB is responsible for operating and administering an independent disciplinary scheme (the Accountancy Scheme) covering members of the following accountants' professional bodies:- the Association of Chartered Certified Accountants, the Chartered Institute of Management Accountants, the Chartered Institute of Public Finance and Accountancy and the Institute of Chartered Accountants in England and Wales; The Institute of Chartered Accountants of Ireland and the Institute of Chartered Accountants of Scotland.

The AADB also operates & administers a separate independent disciplinary scheme (the Actuarial Scheme) covering members of the Faculty & Institute of Actuaries.

The AADB's role is the investigation, and, where appropriate, hearing by disciplinary tribunal of public interest cases; other cases will continue to be dealt with by the individual accountancy body of the member concerned or by the Faculty & Institute of Actuaries. The normal channel of reference to the AADB for 'public interest' cases will be the accountancy or actuarial body primarily concerned. However, the AADB also has the power to call in cases whether or not they have been referred to it by an accountancy or actuarial body.

The AADB was formerly known as the Accountancy Investigation & Discipline Board (AIDB). It changed its name to the AADB on 16/08/2007.
