A: Before you can put your property on the market it is a legal requirement that you have an energy assessment certificate or EPC. The purpose of the certificate is to record how energy-efficient a property is, likely energy costs and how to improve the energy efficiency of your home. It is not possible to fail an energy rating inspection since the EPC only provides simple information to your buyer which they can choose to act on.
The certificate will provide a rating of the property from A to G, where A is very efficient and G is very inefficient.
Two ratings are shown. The energy-efficiency rating is a measure of a home's overall efficiency. The rating is based on the performance of the building itself and its services (such as heating and lighting).
The certificate also shows the potential rating of the building, if all the cost-effective measures were installed. The ratings will vary according to the age, location, size and condition of the building. The potential rating on the certificate will take these factors into account, and the suggested measures are tailored so that they are realistic for the particular building.
