Your DEC needs to be shown publicly and updated every year.
The purpose of DECs is to 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 within the validity period of the DEC. An affected organisation must display a DEC in a prominent place clearly visible to the public and have in its possession or control a valid advisory report. The advisory report contains recommendations for improving the energy performance of the building.
Validity period of DECs Where the building has a total useful floor area of more than 1,000m², the DEC is valid for 12 months. The accompanying advisory report is valid for seven years. Where the building has a total useful floor area of between 250m² and 1000m², the DEC and advisory report are valid for 10 years.
