Questions and Answers
Who needs a DEC?
Currently the requirements for DEC’s only lie with public buildings, otherwise defined as a building occupied by a public authority or institution providing a public service to a large number of people and therefore frequently visited by those persons. All buildings above 250m² require a DEC.
I have multiple buildings on one site, can I have one DEC?
In simple terms, no! Each building is required to have a DEC. There are the occasional exceptions, such as 2 buildings being connected in some way or they share the same energy meters but generally this is not the case.
Will I need to provide any information or documentation?
In order to produce a DEC, one year’s utility data will be required. This can be either be copies of the bills or we are happy to contact your utility suppliers on your behalf, with an authorisation letter from yourselves.
Any plans you may have would prove very useful, although this is not essential. And our assessor will need access to any maintenance records you have.
How long are DECs valid for?
For all buildings over 1000m², DECs are valid for one year and need to be renewed annually. For buildings between 250 – 999m² the DECs are valid for 10 years.
I hear you need an advisory report, is this true?
Yes, advisory reports are required to accompany any DEC. Unlike the DEC, the AR is valid for up to seven years, and does not have to be updated annually.
What are the implications of not complying?
Trading Standards can issue penalty charges for non-compliance. The fines currently stand at £500 per building for failure to display a DEC at all times, and £1000 per building for failure to possess or have in control a valid advisory report.
Can the Display Energy Certificate be used for Commercial Buildings?
At the moment commercial buildings are exempt from this particular legislation. However, due to the DEC being based upon actual billing data, and the way the buildings are used, they are becoming increasingly popular at a voluntary level.
DEC’s came into force on 1st October 2008. The Department of Energy, and Climate Change, state that the purpose of introducing DEC’s was to raise public awareness of energy use, with a view to steering the governments carbon reduction frameworks, whereby a cut of 80% from 1991 CO2 emissions rates is required by 2050.
Display Energy Certificates (DEC) shows the operational rating (OR) of a building based on actual energy consumption taken from billing data over 12 month period. This information is compared to a hypothetical building with performance equal to one typical of its type (the benchmark). Typical performance for that type of building would have an OR of 100.
An Advisory Report (AR) accompanies the DEC, and is a document that highlights various recommendations to improve the energy performance of the building. Such recommendations may be operational and management improvements, possible upgrades to the building fabric or services, and opportunities for the installation of low and zero carbon technology.Contact us about Display Energy Certificates
