What is a Display Energy Certificate?

A Display Energy Certificate shows the energy performance of a building that is based upon the energy consumption recorded annually over the last three years. It contains two parts Rating and Advisory report.

A DEC certificate is valid for one year and must be updated annually.

Why Display Energy Certificates are required?

The formal purpose of Display Energy Certificates (DEC certificates) is to raise public awareness of energy use and to enlighten visitors to public buildings about their respective energy efficient levels.

DEC certificates provide an energy rating of the building from A to G

Buildings requiring a Display Energy Certificate

A DEC and advisory report are required for buildings with a total useful floor area over 500m2 that are occupied in whole or part by public authorities and visited by the public.

For the purposes of the regulations, a building is defined as, ‘a roofed construction having walls, for which energy is used to condition the indoor climate, and a reference to a building includes a reference to a part of a building which has been designed or altered to be used separately.

Public Authorities include:

  • Central and local government
  • NHS trusts
  • Schools, colleges, universities
  • Police
  • Courts
  • Prisons
  • Army
  • Executive agencies
  • Statutory regulatory bodies
  • Leisure centres (but not private clubs)
  • Hospitals, Nursing homes, etc
  • Municipal golf clubhouses
  • Public Libraries
  • Museums & Art Galleries provided by Public Authorities

When Display Energy Certificates are required?

From January 2013 you will need to display a DEC certificate showing an Operational Rating in a prominent place clearly visible to the public for buildings bigger than 500 m2

What an advisory report contains?

The advisory report contains recommendations for possible improvements and these include cost effective measures for improving the building’s energy performance.

The report includes low-cost operational and management improvements, improvements to the building fabric or services and opportunities for the installation of Low and Zero Carbon (LZC) technologies.

The report enables the occupier to identify what may be done to improve building energy management, building services, and therefore reduce energy consumption and CO2 emissions.

The advisory report lists the recommendations by payback period as follow :
• Short-term payback (up to three years), for example building energy management measures
• Medium-term payback (three to seven years), for example upgrading building services
• Long-term payback (more than seven years), for example Low and Zero Carbon (LZC) technologies.

Penalties for not having a DEC certificate

A local authority can issue a penalty charge notice of £1500 for failing to display a DEC certificate at all times.

In addition to these penalties, it will still be necessary to commission the documents; otherwise further offences will be committed.
