What is an Energy Performance Certificate?

An Energy Performance Certificate (EPC) provides a rating for the energy performance of a building. The ratings are standard so the energy efficiency of one building can easily be compared with another building of a similar type.

EPCs are similar to the certificates now provided with domestic appliances such as refrigerators and washing machines. They give building owners, occupiers and purchasers information on the energy efficiency and carbon emissions of their building.

The EPC rates the energy efficiency and carbon emissions of a property on a scale of A to G, where A is the best.

A recommendation report is attached to the certificate, providing information about ways to improve the energy efficiency of the property.

The certificate also shows the rating that could be achieved if all the recommendations were implemented.

When do I need to have an Energy Performance Certificate?

EPCs are only needed for buildings when they are constructed, sold or rented. It is the responsibility of the person selling or renting a building to have a Valid EPC to show to prospective buyers and tenants. The EPC must be given to the eventual buyer or tenant.

There is no requirement to get an EPC for buildings that are just being occupied normally other than when they are being sold or let.

What does an Energy Assessment involve?

An accredited Energy Assessor needs to visit a property to conduct an energy assessment. During the assessment they collect information on the property, which includes details of its dimensions, construction and heating/hot water provision.

This information is fed into the approved software programme which produces the EPC and recommendation report.
