Display Energy Certificates (DECs) and Advisory Reports (ARs)

Are you a "public authority or an institution providing a public service (further defined as 'one providing a service traditionally associated with local or national Government') to a large number of persons and therefore visited by those persons"? Does your building have a total useful floor area over 1,000m²? You require a DEC and AR.

Many organisations who do not require DECs by law are carrying them out voluntarily to enable them to monitor and target reductions in their energy use.

Coles Knapp are fully accredited to provide DECs and ARs and offer a quick, reliable and competitive service. All Coles Knapp DECs are carried out by our own assessors, in house, ensuring the best value for you, the client.

Background Information / FAQs

What is a DEC/AR?
Display Energy Certificates (DECs) show the actual energy usage of a building, (the ‘Operational Rating'), and help the occupier and the public see the energy efficiency of a building. This is based on the energy consumption of the building as recorded by gas, electricity and other meters. The DEC should be clearly displayed at all times and clearly visible to the public. A DEC is always accompanied by an Advisory Report that lists cost effective measures to improve the energy rating of the building.  More information can be obtained at the Communities Govt. website here.

Do I need a DEC/AR?
Only buildings with a total useful floor area over 1000m² that are occupied or part occupied either by public authorities and by institutions providing public services to a large number of people and therefore visited by those persons are affected by this legislation.
Where a building is partly occupied by a public authority or a relevant institution, the authority or institution is responsible for displaying a DEC and having a valid advisory report.
Other private organisations occupying the building, irrespective of the size they occupy, do not need to display a DEC.

When is the DEC required?

If you fulfil the criteria for a DEC, you have legally required one since October 1st 2008. They have to be renewed annually and the Advisory Report renewed every 7 years.

How long is a DEC/AR valid for?

The DEC is valid for one year. The accompanying Advisory Report is valid for seven years.

Are there any circumstances where I don't need an DEC?

If you fulfil the criteria for a DEC there are no further exceptions.

What happens if I do not have an DEC/AR?

The penalty is £500 for failing to display a DEC at all times in a prominent place clearly visible to the public and £1,000 for failing to have possession of a valid advisory report. In addition to these penalties, it is still necessary to commission the documents
