DEC Assessment

What is a DEC Assessment?

Display Energy Certificates (DECs) show the energy performance of public buildings. All public buildings with a total useful floor area greater than 250m² are obligated to have a Display Energy Certificate (DEC) and advisory report. The report uses a scale from ‘A’ to ‘G’ – ‘A’ being the most efficient and ‘G’ being the least.

Once our accredited Energy Assessor has completed your report it should be displayed on A3 or large in a prominent place clearly visible to members of the public. Fines can be issued for failing to display a DEC and for not having valid updated advisory report. Please note that Advisory Reports should be updated on a yearly basis.
