Display Energy Certificates

BSSEC are accredited providers of Display Energy Certificates for your buildings.

All public buildings in England and Wales require a Display Energy Certificate (DEC) showing actual energy use, and not just the theoretical energy rating.

DECs show the actual energy consumption of a building, the Operational Rating, and help the general public to understand the energy efficiency of a building. The DEC rating is based on the energy consumption of the building from all energy sources, including gas, electricity and fuel oil, over a 12 month period. The DEC must be clearly displayed at all times and made visible to the public.

Who needs a DEC?

DECs are required for buildings with a total useful floor area over 250m² that are occupied by a public authority or institution providing a public service to, and visited by, a large number of persons.

Where the building has a total useful floor area of more than 1,000m², the DEC is valid for 12 months. The accompanying advisory report is valid for seven years. Where the building has a total useful floor area of between 250m² and 1000m², the DEC and advisory report are valid for 10 years.
