An energy performance certificate (EPC) is valid for 10 years from the date on which it is issued, or until a newer EPC is issued for the building concerned, unless it is to be used as one of the prescribed documents in a home information pack (HIP), which is required to be in place for all residential properties marketed for sale in England and Wales, in which case it will be valid for three years from the date on which it is issued.
Information about the number of energy performance certificates (EPCs) lodged in England and Wales in both the domestic and non-domestic sectors is available on the EPC register website at:
www.epcregister.com
There is no central register for the number of home information packs however we estimate that 1.1 million home information packs have been produced during the period 1 July 2008 to 30 June 2009.
Local authority trading standards offices and the Office of Fair Trading have statutory responsibility for enforcing the home information pack duties through s.166 and s.175 of the Housing Act 2004. The information requested is not held centrally.
