Display Energy Certificates

What are DECs?

Display Energy Certificates known as DECs, promote the improvement of the energy performance of buildings occupied by a public authority and form part of the implementation of the Energy Performance of Buildings Regulations 2012 (England & Wales).

The purpose of DECs is to raise public awareness of energy use and to inform visitors to public buildings about the energy use of a building. DECs provide an energy rating of the building from A to G (A being very efficient and G being the least efficient).

DEC and accompanying advisory report are required for buildings with a total useful floor area of over 250m2 occupied wholly or partly by public authorities and are frequently visited by the public.

Local authorities can issue a penalty charge notice of £500 for failing to display a DEC at all times in a prominent place clearly visible to the public, and £1,000 for failing to possess or have in their control a valid advisory report.
How long is a Display Energy Certificate (DEC) valid?

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 500m² and 1,000m², the DEC and advisory report are valid for 10 years. Our service
