Display Energy Certificates


Display Energy Certificates have been introduced to raise awareness of the energy efficiency of buildings that are frequently visited by the public. These include buildings that are occupied by public authorities and institutions that have a total useful floor area over 1000m².

The DEC must be displayed in a prominent position visible to the public on a minimum of A3 size paper. The certificate shows the actual amount of metered energy used by the building over a 12 month period. The rating for the building is shown in an A to G format with A being the most efficient and G being the least efficient.

The certificates are valid for 12 months and must then be renewed. An advisory report identifying possible actions that could be taken to reduce the buildings energy consumption will be provided with the DEC which is valid for 7 years.

The DEC's are required to be on display by the 1st of October 2008 and the building owner must be in possession of a valid advisory report.

  • Central and local Government

  • Schools & Education Centres
