Energy Performance Certificates

Energy performance certificates and display energy certificates have an important role to play in improving the energy efficiency of buildings.

Two types of energy certificate are required in different circumstances:

• Energy Performance Certificates (EPCs) for all buildings when they are constructed or marketed for sale or rent.

• Display Energy Certificates (DECs) for large, public buildings occupied by public authorities or institutions providing a public service to a large number of persons and therefore frequently visited by those persons.
