An Energy Performance Certificate or EPC informs home buyers, sellers, landlords and tenants about a property's energy efficiency. A to G ratings, like those used to rate fridges and washing machines are generated further to a part-survey and the home's energy rating will be attached to the sales particulars. Estate Agents are obliged to provide this information to prospective buyers.

The EPC will also make recommendations for cost-effective improvements that can be made to help cut fuel bills and carbon emissions. According to Government figures, homes currently account for 27% of the UK's carbon emissions, contributing to global climate change. The EPC is prepared by Domestic Energy Assessors or Home Inspectors who are members of a Government approved Certification Scheme. The Government estimates that by following the recommendations in an EPC, an average of £300 a year can be saved in fuel bills.

This initiative has been extended to rental properties and it is now the responsibility of all landlords to have an EPC available for inspection at the start of a tenancy.
