The certificate records how energy efficient a property is as a building and provides A-G ratings.

Certificates are produced using standard methods and assumptions about energy usage in order that the energy efficiency of one building can easily be compared with another building of the same type. This allows prospective buyers, tenants, owners, occupiers and purchasers to access information as to the energy efficiency and carbon emissions from a building in order to consider energy efficiency and fuel costs as part of any investment.

An EPC is always accompanied by a recommendation report that lists cost effective measures (such as low and zero carbon generating systems) to improve the energy rating. A rating is also given showing what could be achieved if all the recommendations were implemented.

The EPC is important because nearly fifty per cent of the UK’s energy consumption and carbon emissions arise from the way our buildings are lit, heated and used. Even comparatively minor changes in energy performance and the way we use each building will have a significant effect in reducing energy consumption.

What are Display Energy Certificates?

Display Energy Certificates or DEC must be displayed in public buildings. The certificate must be displayed in a public place in each building.

The DEC is valid for twelve months and is required to be updated annually. The Advisory Report which contains recommendations for improving the energy performance of the building and its energy usage is valid for seven years.
