The Energy Performance Certificate (EPC) is broadly similar to the labels now provided with domestic appliances such as refrigerators and washing machines.

When the construction of a new building is completed, the builder or person responsible for the construction is responsible for obtaining the certificate and providing it to the owner. This is a duty under Building Regulations. This will also apply if a building is converted into fewer or more units and there are changes to the heating, hot water provision or air conditioning/ ventilation services.

Communities and Local Government (CLG) is leading the introduction of a number of energy and cost savings measures to make all buildings more efficient. The measures are being applied across all European Union countries and are in line with the European Directive for the Energy Performance of Buildings (EPBD).
