What are Display Energy Certificates (DECs)?

Display Energy Certificates provide in-depth analysis of how efficiently you use the buildings including recommendations on improvements.

They are a statutory requirement for public buildings with an internal floor area over 250m square.

Public authorities must display their DEC in a prominent place clearly visible to the public, e.g. near the building’s entrance.

They can be fined £500 if they don’t.


What a DEC will tell you

Display Energy Certificates (DECs) are designed to show how efficiently energy is being used in a building.

They use a scale that runs from ‘A’ to ‘G’ – ‘A’ being the most efficient and ‘G’ being the least. Ratings from A to D indicate that a building is using energy more efficiently than is typical for buildings of its type. For buildings with an internal floor area exceeding 1000m square DECs need to renewed annually. For all smaller buildings above 250m square DECs need to be renewed once every 10 years.

Your recommendations report

The recommendations report accompanies the DEC and contains specific advice on improving the energy performance of the building. The recommendations cover cost-effective measures that may be implemented to improve the energy performance of the property with paybacks in the short, medium and long term.

How do you get a DEC?

We have a number of qualified DEC assessors in the team who provide DECs to schools throughout North Yorkshire. DECs can be purchased as and when you need them or as part of one of our Packages. If you have purchased a primary or secondary package you will be contacted at the time when you are due your DEC and we may need to book a visit to survey your school.
