Contact the Adjudicator’s Office

The Adjudicator’s Office investigates complaints about HM Revenue and Customs (HMRC) and the Valuation Office (VO).

You must first complain to HM Revenue and Customs (HMRC) or the Valuation Office (VO) before the Adjudicator’s Office can investigate your complaint.

You can ask HMRC or the VO for a:

  • first review to consider your complaint
  • second review if you do not agree with the outcome

We review Home Office decisions on entitlement to compensation made under the Windrush Compensation Scheme. In addition, we investigate complaints about how the Home Office handled a claim for compensation made under the Windrush Compensation Scheme.
