Energy Performance Certificates

If you are selling, renting or constructing a property you are required to provide an Energy Performance Certificate for that property.

This certificate tells you how energy efficient your property is and is based on the following:

  • The construction of the property
  • Insulation built into the property
  • The heating system installed in the property
  • The lighting system installed in the property.

The Energy Performance Certificate remains valid for 10 years, however you should renew the certificate if you carry out any major refurbishment or building works to the property which would alter its energy rating.

Letting and Estate Agents are required to include an Energy Performance Certificate with any information they use to market the property.

An Energy Performance Certificate is not required for the following properties:

  • Places of worship
  • Temporary buildings
  • Detached buildings less than 50m2 with the exception of dwellings.

To get an Energy Performance Certificate you will have to employ the services of an Energy Assessor in your area at http://www.niepcregister.com. The Energy Assessor will record the Energy Performance Certificate on the Northern Ireland register which you can access on http://www.niepcregister.com.

Display Energy Certificates (DECs)

DECs are required for buildings that have an entire useful floor area of more than 250m² and that are occupied by a public authority or an institution that provides a public service, and are frequently visited by members of the public. This certificate shows the actual energy usage of the building and allows the public to see how efficient the property is and is based on the energy consumption of the building recorded by gas, electricity and other meters. 

The DEC is valid for one year, with the associated Advisory Report valid for seven years. The DEC should be displayed in a prominent location and always clearly visible to the public.  

To obtain a DEC you will have to employ the services of an Energy Assessor in your area at http://www.niepcregister.com. The Energy Assessor will record the DEC on the Northern Ireland register which you can access on http://www.niepcregister.com.
