Display Energy Certificate


Display Energy Certificates

Meet your regulatory obligations and understand how to reduce your carbon footprint


What is a Display Energy Certificate (DEC)?

Display Energy Certificates (DECs) demonstrate the energy performance of buildings occupied by public bodies. A DEC provides an energy efficiency rating of the building based on the actual amount of metered energy used.

DECs provide an energy rating of the building from A to G, where A is very efficient and G is the least efficient.

Supporting your carbon and cost-saving objectives

Our market-leading service for compliance with regulations for Display Energy Certificates helps organisations save both energy and money.

We are committed to reducing carbon emissions through supporting our clients with effective energy management. We all have a responsibility to reduce our use of lighting, computers, heating and other energy consuming equipment to reduce the level of CO2 produced and help to mitigate climate change.

We can help you act on your DEC to further identify opportunities to save energy and money.
Ask us about our additional technical services that can help you achieve your energy, carbon and cost saving objectives.


Do I need a DEC?

A valid DEC and Recommendation Report are legally required documents for every publicly funded building over 250m² that is frequently visited by the public.

For buildings over 1,000m² a DEC is required annually, and the Recommendation Report needs to be renewed every seven years.

For buildings between 250m² and 999m² a DEC and Recommendation Report are required every 10 years. Fines of up to £1,000 can be levied for non-compliance.

Organisations must display the certificate in a prominent place clearly visible to the public and also hold a valid Recommendation Report. The Report contains recommendations for improving the energy performance of the building.


Special offer

Our competitively priced package offers a complimentary Display Energy Certificate for the first year for customers who take up a three-year service, offering reassurance that your school remains compliant while removing the hassle of finding a supplier.

What you can do to improve energy efficiency

Staff and members of the public can play a big part in improving energy efficiency.
Please help with the following simple actions:

Keep lights switched off on bright days to make the most of natural light, and ensure lights are switched off in vacant rooms or when the building is closed.
Avoid the use of portable electric heaters during the winter and electric fans during the summer.
Report areas of overheating so that the heating controls can be adjusted.
Switch off computers, printers, photocopiers and other office equipment at the end of each day and at the weekend.
During cold weather keep windows and external doors closed to avoid heat loss and draughts, and wear more clothing to make you comfortable.
Turn off taps after use (especially the hot tap) and report leaking taps so that they can be repaired.
