The Adjudicator’s Office is a UK non-departmental public body which was set up in 1993, initially to look into complaints about the Inland Revenue (including the Valuation Office Agency). HM Customs and Excise and the Contributions Agency joined in 1995. From 2003 the office also took on complaints about The Insolvency Service. In April 2005, the role continued in relation to HM Revenue and Customs (HMRC), which was formed by the merger of the Inland Revenue and HM Customs and Excise.

In March 2015, the Adjudicator was asked to become the independent reviewer for complaints about HM Treasury, Pension Wise. There were no complaints from Pension Wise during its first year. Following the move of Pension Wise to the Department for Work and Pensions (DWP), from 1 April 2016, Pension Wise complaints have been considered by DWP. The Insolvency Service took its investigation of complaints in house in early 2016–17.

The Adjudicator is an independent appointment agreed by the organisations for which she adjudicates.
