What are Display Energy Certificates?

All public buildings with a total useful floor area greater than 250m² are obligated to have a Display Energy Certificate (DEC) and advisory report. DECs are required to inform how energy efficient a public building is and can be a route to ESOS compliance as an alternative to energy audits.

It states an energy rating from A-G and is based on the performance potential of the building (fabrics) and its services (heating, ventilation, lighting). The DEC comes with a recommendation report demonstrating how the energy performance can be enhanced.

Public Display Energy Certificates can only be produced by an accredited Energy Assessor and should be displayed no smaller than A3 in a prominent place clearly visible to members of the public. Fines can be issued for failing to display a DEC and failing to have a valid advisory report.

DECs and Advisory Reports Validity Periods:
