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.


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 improved.

DEC 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.


The DEC shows the actual energy usage of a building. This is based on the energy consumption of the building as recorded by gas, electricity and other meters.
