Following the change of government we are reviewing all content on this website.
Homes currently account for 27 per cent of the UK's carbon emissions, contributing to global climate change.
The way in which we light, heat and use our homes all contribute to this. Even small improvements to the energy performance and the way we use our homes could have a significant effect on our fuel bills and carbon emissions.
Energy Performance Certificates have been introduced to help improve the energy efficiency of all buildings - including homes. If you are buying or selling a home it is now law to have an Energy Performance Certificate. They are also required on construction of new homes and are needed for rented homes the first time the property is let after 1 October 2008.
EPCs form part of a programme of work that will make a difference to the 50 per cent carbon emissions from buildings. Other changes include providing advice to users on the energy efficiency of their heating and hot water systems.
