Domestic EPCs

An Energy Performance Certificate (EPC) will be required for all homes whenever built, rented or sold, and from the 6th April 2009 is mandatory from the first day of marketing.

If you are renting or selling a domestic property it is now law to have a certificate. The certificate records how energy efficient a property is as a building and provides A-G ratings. These are similar to the labels now provided with domestic appliances such as refrigerators and washing machines. (see EPCs)

They are produced using standard methods and assumptions about energy usage so that the energy efficiency of one building can easily be compared with another building of the same type. This allows prospective buyers, tenants, owners, occupiers and purchasers to see information on the energy efficiency and carbon emissions from their building so they can consider fuel costs as part of their investment.

An EPC is always accompanied by a recommendation report that lists cost effective and other measures (such as low and zero carbon generating systems) to improve the energy rating. A rating is also given showing what could be achieved if all the recommendations were implemented.

The certificate is important because nearly 50 per cent of the UK's energy consumption and carbon emissions arise from the way our buildings are lit, heated and used. Even comparatively minor changes in energy performance and the way we use each building will have a significant effect in reducing energy consumption.
