Questions and Answers

Do I need a Commercial EPC Certificate?

If you are a property owner in the process of selling or leasing your property, then the answer is yes!  EPC Certificates became a regulatory requirement in April 2008.  Commercial EPC Certificates are a requirement on all commercial properties, that are either being sold, built, or rented, and must be provided to a prospective buyer or tenant free of charge.

Are there any cases where my building may be exempt?

Yes.  The following situations may deem your property exempt:

  • Places of Worship
  • Temporary Buildings that will be used for less than 2 years.
  • Stand-alone commercial buildings with a total useful floor space of less than 50m²
  • Industrial sites, workshops and non-residential agricultural buildings that have a low energy demand.
  • Some buildings that are due to be demolished.
  • Some listed buildings.


How long does the process take?

This largely depends on the size of the building, but it can take anything from 1 hour to 5 days.  Once the assessor has completed the site survey we aim to have the completed EPC Certificate back to you within 24-48 hours.  If we anticipate it to be longer than this, we will always let you know before starting the job.

How much does it cost?

This varies dependent on size, locality, complexity and volume.  We are happy to offer discounts for large consignments.  Get in touch for a no obligation quotation.

When do I pay?

We never ask for payment up front.  Invoices are issued once the EPC Certificate has been completed and you are 100% happy.


The Commercial EPC Certificate tells owners and potential buyers/tenants of properties about the energy efficiency of a building, the Commercial EPC provides an asset rating for a building which is based on the potential performance of that building against government benchmarks and shows how the asset rating can be improved if all the recommendations are followed. Ratings are represented with a chart with grades from ‘A’ to ‘G’, where ‘A’ is the most energy efficient and ‘G’ is the least.

Only an accredited Energy Assessor can undertake a Commercial EPC. The Energy Assessor must visit the building in person to ensure that the data is accurate.

Once an energy assessor has been commissioned to produce a Commercial EPC, there are three main steps to performing the assessment, which are:

  • Gathering the relevant information about the building
  • Analysing the information and identifying different zones of the building
  • Entering the information into an approved software programme. The appropriate methods for commercial buildings are SBEM – Simplified Building Energy Model or DSM – Dynamic Simulation Model (even if the building was originally used for residential accommodation).


During the assessment the energy assessor will collect information about the building. This will include plans, dimensions of the building, its purpose, the number of floors, the amount and type of glazing (i.e. single or double glazing), the heating systems and the fuel used.

This information will be fed into an approved software programme using a Government approved energy assessment method. The software produces the certificate and the recommendation report for the building.

The energy assessor will then record the certificate onto the national register via his or her accreditation body and provide the seller or prospective landlord with the Commercial EPC.
