Display Energy Certificate (DEC)
What is a Display Energy Certificate (DEC)?
A Display Energy Certificate (DEC) shows the energy performance of a building, based on the operational rating*. The rating scale ranges from A (very efficient) to G (least efficient). A DEC must be accompanied by an advisory report which outlines how an organisation can reduce energy consumption.
Public authorities must have a DEC for a building if the following criteria apply:
- The building is at least partially occupied by a public authority (e.g., council, leisure centre, college, NHS trust etc).
- The building has a total floor area of over 250 square metres.
- The building is frequently visited by the public.
How long are Decs valid?
DEC’s are valid for one year for buildings with a total useful floor area of more than 1000m². They last for 10 years when the total useful floor area is over 250 m² and up to 1000m².
DEC’s were introduced to improve the energy efficiency of buildings and inform visitors about energy usage as part of the implementation of the Energy Performance of Buildings Regulations 2012 (England & Wales).
Local authorities can issue a penalty charge notice of £500 for failure to display a DEC, with a further £1000 for failure to obtain an advisory report.
