Starting on 9 July 2015, the Display Energy Certificates (DECs) will be required for all buildings over 250 square metres occupied by a public authority and frequently visited by the public. The threshold for requiring these certificates was prior to this change 500 square metres.
The Department of Communities and Local Government (DCLG) said: “The purpose of this change is to further raise public awareness of energy use and to inform visitors to public buildings about the energy use of a building. DECs provide an energy rating of the building from A to G, where A is very efficient and G is the least efficient and are based on the actual amount of metered energy used by the building over the last 12 months.”
“Affected organisations must display a DEC in a prominent place clearly visible to the public and have in its possession or control a valid recommendation report.”
