Display Energy Certificates

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 1,000m 2 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.

To help with implementation a new DVD has been produced to help public authorities understand the DEC and what they need to do. The DVD is available on our website (see link on right) - and features buildings which have had a DEC assessment.

This includes Eland House - Communities and Local Government HQ - which has been given a F rating. An energy efficiency action plan is now being developed to help improve next year's rating and replace equipment nearing end of life based on the advisory report that comes with the DEC.
