Energy Performance Certificates (EPCs)

Energy Performance Certificates (EPCs) have been a requirement for commercial buildings greater than 50m2 whenever built, rented or sold since 2008. They are valid for ten years.

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

They are produced using standard methods and assumptions about energy usage so 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 see information on the energy efficiency and carbon emissions from their building so they can consider energy efficiency and fuel costs as part of their investment.

An EPC is always accompanied by a recommendation report that lists cost effective and other measures (such as low and zero carbon generating systems) to improve the energy rating. Each recommendation is assessed against the potential impact over three payback periods in addition to other measures based on an understanding of the building and indicates whether the impact is High, Medium or Low.

The certificate is important because nearly 40% 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 and carbon emissions.

You must display an EPC by fixing it to your commercial building if all these apply:

  • the total useful floor area is over 500m2
  • the building is frequently visited by the public
  • an EPC has already been produced for the building’s sale, rental or construction

The certificate provides a rating for the building, showing its energy efficiency.

Each rating is based on the performance of the building itself, based on its usage, construction and its services (such as heating and lighting). This is known as an asset rating. The ratings will vary according to the age, location, size and condition of the building.
