VATGPB5265 | Police authorities: specific activities: special constables
From HM Revenue & Customs · VAT Government and Public Bodies
Special constables are generally volunteer members of a police force. They are part of the police authority and so any VAT incurred on their costs is recoverable under section 33 (see VATGPB4000).
A limited number of forces are permitted to reimburse certain authorised and verifiable expenses incurred by individual officers. These payments are outside the scope of VAT.
