From 1 October 2008 all buildings whenever sold, built or rented will need an Energy Performance Certificate (EPC).
The certificate provides energy efficiency A-G ratings and recommendations for improvement. The ratings - similar to those found on products such as fridges - are standard so the energy efficiency of one building can easily be compared with another building of a similar type.
Acting on an EPC is important to cut energy consumption, save money on bills and help to safeguard the environment.
EPCs were first introduced for the marketed sale of domestic homes, as part of the Home Information Pack. If you are buying or selling a home it is now law to have a certificate. From April this was extended to newly built homes and large commercial properties. By 1 October 2008 all buildings whenever built, sold or rented will require one, including those on the market before the phased introduction of EPCs for domestic properties in 2007.
