Display Energy Certificates

Display Energy Certificate

Display Energy Certificates (DECs) show the actual energy usage of a building – also known as the operational rating – and help the public see how energy efficient a building is. They look a bit like the energy rating notice displayed on fridges and other white goods, with ratings from A to G. All County Council owned buildings with a total useful floor area of more than 500m2 are obliged to have a DEC, which should be clearly displayed at all times and an associated advisory report (AR). 

The legislative requirements are not the same for all building sizes, but to summarise:

  • If you are a site with buildings of floor area between 500m2 and 1000m2 , and have not yet obtained a DEC (with its associated AR), you are required to do so as of January 2013. For sites with buildings of this size that have already obtained their DEC and AR, we would encourage you to renew the DEC each year, as it is an excellent way of monitoring your performance and communicating your progress and commitment in being more energy efficient. Buildings of this size are only required by the legislation to have a DEC and associated AR renewed every 10 years.
  • If you are a site with buildings of floor area above 1000m2 , then you are required to have an annually renewed DEC, and an AR every 7 years. 

There are financial penalties for failing to display a DEC at all times in a prominent place, clearly visible to the public, and for failing to have possession of a valid advisory report.

The Council's participation agreement for the provision of Display Energy Certificates provides value for money in meeting schools' legal requirements in this area, removing some of the burden involved and allowing us to keep track of progress in our work to try and make our schools more energy efficient.
