HMRC have issued Revenue & Customs Brief 09/14 here: http://www.hmrc.gov.uk/briefs/vat/brief0914.htm
This provides guidance on the direct tax and VAT treatment of income received from, and charges made in connection with, activities involving Bitcoin and other similar cryptocurrencies. Bitcoin operates via a peer to peer network, independent of any central authority or bank. All functions such as issue, transaction processing and verification are managed collectively by this network.

The advent of cryptocurrencies such as Bitcoin is a new and evolving area. Bitcoin may be held as an investment (i.e. for trading with recognised currencies) or used to pay for goods or services at merchants where it is accepted. In the UK, there are already a number of outlets, including pubs, restaurants and internet retailers, that accept payment by Bitcoin.

In summary, the VAT treatment of Bitcoin activities will generally either be outside the scope of VAT or exempt from VAT (under Article 135(1)(d) of the VAT Directive), depending on the specific transaction involved. However, VAT will be due in the normal way on transactions involving any goods or services sold in exchange for Bitcoin or other similar cryptocurrency.

In the UK, as is the case with any other currency, the value of the supply of goods or services on which VAT is due will be the £sterling value of the cryptocurrency at the point the transaction takes place.
