More about EPCs and DECs…

Energy Performance Certificates (EPCs)

  • Legal requirement to provide an Energy Performance Certificate (EPC) to the occupier for buildings with a useable floor area over 500 m2 when they are built, sold, sublet, or substantially refurbished.


Display Energy Certificates (DECs)

  • A DEC must not be confused with an EPC (Energy Performance Certificate). An EPC shows the potential of the building, whilst the DEC is the actual energy performance.
  • Building with a useable floor area over 1000 m2 – certificate requires annual renewal.
  • Buildings with a total floor area between 500 to 1000 m2 – DECs will be valid for 10 years.
  • Mandatory display of DECs for all public buildings and institutions with a floor area of over 500m2 (England and Wales).


Undertaking a DEC requires the following information:

    • Type of building
    • Annual energy usage (electricity and gas bills).
    • Total floor area
    • Method to cool and heat the building
