Display Energy Certificates (DEC)

Our service provides all that is needed to gain a Display Energy Certificate (DEC) for a publicly administered building.

Display Energy Certificates (DECs) show the actual energy usage of a building, the Operational Rating, and help the public see the energy efficiency of a building. This is based on the energy consumption of the building as recorded by gas, electricity and other meters.

The DEC should be clearly displayed at all times and clearly visible to the public. A DEC is always accompanied by an Advisory Report that lists cost effective measures to improve the energy rating of the building.

Display Energy Certificates are only required for buildings with a total useful floor area over 250 m2 that are occupied by a public authority and institution providing a public service to a large number of persons and therefore visited by those persons. They are valid for one year. The accompanying Advisory Report is valid for seven years.

The requirement for Display Energy Certificates came into effect on 1 October 2008.

Failure to comply may result in a fine of £1000
