The UK Government classifies bodies into four main types. The Scottish Government also has a fifth category:
NHS bodies.
Advisory NDPBs These bodies consist of boards which advise ministers on particular policy areas. They are often supported by a small secretariat from the parent department, and any expenditure is paid for by that department.
Executive NDPBs These bodies usually deliver a particular public service and are overseen by a board rather than ministers. Appointments are made by ministers following the Code of Practice of the
Commissioner for Public Appointments. They employ their own staff and allocate their own budgets.
Tribunal NDPBs These bodies have jurisdiction over an area of the
law. They are coordinated by
His Majesty's Courts and Tribunals Service, an
executive agency of the
Ministry of Justice, and supervised by the
Administrative Justice and Tribunals Council, itself an NDPB sponsored by the Ministry of Justice.
Independent monitoring boards These bodies were formerly known as "boards of visitors" and are responsible for the state of prisons, their administration, and the treatment of prisoners. The
Home Office is responsible for their costs and has to note all expenses. ==Contrast with executive agencies, non-ministerial departments and quangos==
