Display Energy Certificate DEC

How do I get a DEC?

An Energy Assessor, accredited to produce display energy certificates for that type of building, is
the only person who can produce a DEC and Advisory Report for your building. They will use the
approved calculation method for the Operational Ratings figures.

Firstly the energy consumption data you provide will be reviewed by the assessor in line with the
approved method. Adjustments may be made for occupancy, intensity of use, special energy uses,
weather and climate.

The carbon dioxide emissions for the certificate are based on the adjusted energy consumption
and total useful floor area1 and building type to give a measured CO 2 emission per square metre.

The assessor will then produce a DEC and an Advisory Report from this information in line with the approved method. The DEC will need to be lodged in a national register by the assessor and given a unique certificate reference number.

1 The Total useful floor area is defined as the total area of all enclosed spaces measured to the internal face of the external walls. Included are areas of sloping surfaces such as staircases, galleries, raked auditoria, and tiered terraces where the area taken is from the area on the plan. Excluded are areas that are not enclosed such as open floors, covered ways and balconies.

What does a DEC contain?

A DEC must contain, by law1, the following information:

  * the operational rating and the asset rating (if available) as determined by the government approved method
  * show the operational ratings for the building expressed in any certificates displayed by the occupier during the last two years before the nominated date
  * include a reference value such as a current legal standard or benchmark

The DEC will also show the unique certificate reference number, the address of the building, the total useful floor area2 of the building, the name of the energy assessor, their employer (or trading name if self employed), the name of their accreditation scheme and the date when the DEC was issued. The DEC must be accompanied by an Advisory Report. DECs are valid for 12 months, Advisory Reports 7 years.
