If you have recently had an extension built or other work done to your property which involved obtaining planning permission, be prepared for a letter from HM Revenue and Customs (HMRC).

In an effort to clamp down on ‘cash in hand’ building work, HMRC are reviewing planning permissions granted and have started sending letters to the property owners. The letters include a form requesting details of the builder’s name, address and VAT registration number, the sum paid and how the payment was made (i.e. whether in cash or by cheque).

In order to make a reply as convenient as possible, the enquiry comes with a stamped addressed envelope.
