What is a Display Energy Certificate?

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

Why Display Energy Certificates are required?

The purpose of introducing Display Energy Certificates (DEC certificates) is to raise public awareness of energy use and to inform visitors to public buildings about the energy use of a building. DEC certificates provide an energy rating of the building from A to G

What an advisory report contains?

The advisory report contains recommendations for possible improvements, including cost effective measures for improving the energy performance of the building.

The report includes zero and low-cost operational and management 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, etc. therefore reducing energy consumption and CO2 emissions.

The advisory report categorises the list of recommendations, by payback period as follows:

  • 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.
