The Adjudicator acts as a fair and unbiased referee looking into complaints about HM Revenue & Customs (HMRC), including the Tax Credit Office (TCO), and the Valuation Office Agency (VOA). We also look into complaints about the Public Guardianship Office (PGO) and The Insolvency Service. We investigate and help to resolve complaints from individuals and businesses who remain unhappy about the way their affairs have been handled. The Adjudicator is Dame Barbara Mills QC and her services are free.
