Energy Performance Certificates (EPCs)

Energy Performance Certificates and the RIBA Plan of Work

What are Energy Performance Certificates (EPCs)?

Energy Performance Certificates (EPCs) are a requirement whenever a building is built, rented or sold. The EPC provides an energy performance rating of a building including energy efficiency and carbon emissions. As the first company to lodge a live commercial Energy Performance Certificate, Stroma Built Environment is ideally placed to deliver compliance with this mandatory element of the Energy Performance of Buildings Directive (EPBD).

EPC services – why choose Stroma Built Environment?

Stroma Built Environment’s Energy team has worked with a diverse range of clients, from national and regional property consultants, major car manufacturers and corporate recovery specialists to auctioneers, retailers, major developers and contractors.

Our UK-wide accredited energy assessors can evaluate proposed construction details or carry out a detailed energy survey of the building, perform the necessary energy assessment calculations (in SBEM or DSM) and generate the EPC certificate before lodging it on the Government database, Landmark.


We provide advice on the Private Rented Sector Energy Efficiency Regulations, and their implications . We also assist in identifying the potential impact of the legislation on property portfolios and outline possible remedial measures and an energy efficiency plan.

EPC Assessments

We can undertake EPC assessments on premises that do not already have them or reassess the property’s EPC rating after refurbishment of the property. We can also reassess the property’s EPC rating upon renewal of an existing Energy Performance Certificate.

Green Deal

We offer assistance with obtaining a Green Deal Advice Report and can provide Project Management and facilitation of access to finance through links with Green Deal Providers and Installers.


We undertake SBEM compliance calculations in assessment of a commercial property’s energy consumption.

Explaining Energy Performance Certificates

An Energy Performance Certificate shows a representation of the energy efficiency levels and CO2 emissions of a building. The table goes from A+ to G, A+ being very efficient and G being very inefficient. An EPC is valid for 10 years and is required if you are building, renting or selling a building.

An EPC is accompanied by an Advisory Report (AR) which outlines energy saving measures and recommendations for improving the EPC rating.

There are some buildings which are exempt from requiring an EPC, including:

  • Buildings used as places of worship or for religious activities
  • Temporary buildings
  • Buildings with low energy demand
  • Stand-alone buildings with a floor area of <50m2
  • Buildings that are due to be demolished (certain stipulations apply)
  • Buildings and monuments officially protected as part of a designated environment or because of their special architectural or historic merit

Explaining Energy Performance Certificates

Minimum EPC Ratings – legislative changes

From April 2018, proposed legislative changes within the Energy Act 2011 would make it unlawful to let residential or commercial properties with an EPC rating of F or G. The changes will improve the energy efficiency of privately rented properties in both the domestic and non-domestic sectors. Read more about Minimum Energy Efficiency Standards (MEES).
