What is an Energy Performance Certificate (EPC)?

The purpose of an EPC is to indicate the energy efficiency of a building. The EPC will provide an energy efficiency rating from A to G, where A is the most efficient and G is the least efficient. The better the rating, the more energy efficient the building and the lower fuel bills are likely to be.

Each energy efficiency rating is based on the characteristics of the building itself (the fabric) and its services. This type of rating is known as an asset rating. The asset rating will reflect the age and condition of the building.

The EPC includes recommendations on how the energy performance of the building can be improved (to reduce running costs), together with an indication of the payback period. There is no statutory requirement to carry out any of the recommended energy efficiency measures stated on the EPC.
