Commercial Energy Performance Certificates

Commercial Energy Performance Certificates are a rating of a commercial property’s energy and carbon efficiency.

Valid for 10 years, Commercial Energy Performance Certificates, EPC for short, rate a commercial property’s energy efficiency on a number of factors, including the heating system installed, the insulation and walls, lighting and windows, to provide the property with an overall score out of 100. The result of this grading will place the building in a band between A and G.

What information to expect in an Energy Performance Certificate

Commercial EPCs provide a break down the efficiency of a single commercial property. The EPC can be for the property as a whole or for separate sections of the building.

The Energy Performance Certificate will provide the following information:

– Property information – including the type of property and the size of the property.

– Assessment details – including the date of the certificate, the name of the assessor and a certification reference number.

– Estimated three-year running costs of the property and potential three-year savings.

– An Energy Efficiency Rating – out of 100 and in bands A to G, an overall rating of the property’s energy rating.

– Recommended actions – suggested actions reduce running costs, including estimated costs and savings.

– A summary of the energy performance related features – rated between one and five stars a breakdown of how certain aspects of the property score, includes ratings of: walls, roof, floor, windows, main heating, heating controls, secondary heating, hot water and lighting.

– A n overview of zero carbon energy sources.

– A specific list of recommended measures – including how much they will cost, the savings they can make and the EPC rating after installation.

– The Environmental Impact Rating of the commercial property – scored out of 100 and in bands between A and G, the Environmental Impact Rating scores the property based on its carbon emissions.

– The total annual space heating and water heating demand of the property.

Will I need an EPC for my commercial property?

Yes. Building Regulations sign-off requires an as-built EPC. They are also needed when selling a commercial building. Furthermore, commercial buildings may require multiple EPCs. How a property will be certified depends on the types of heating installed in property, heating installed for the separate parts and considerations on any communal areas.

When’s a Commercial Energy Performance Certificates required?

An EPC must be presented to any potential buyers or tennants. Provision of an EPC in this instant enables interested parties to compare the anticipated running costs with other parties.

An EPC is also required as part of Building Regaulations applications. Upon completion, a new build property will require an On Construction Energy Performance Certificate for building sign off. Generated prior to a build is a Predicted Energ Assessment. As-designed EPCS provide a prediction of the performance of the building for the benefit of interested parties during the build.

Commercial premises may have an existing EPC. Visit the Non-domestic EPC Register for further information.
