Energy Performance Certificates

The Energy Performance of Buildings Directive requires Energy Performance Certificates (EPCs) and Display Energy Certificates (DECs) to be available on all buildings whether residential or commercial, new build or existing.

For domestic property, in England and Wales an EPC must be made available when a property is either sold or let. It is a requirement that any potential purchaser or tenant can see the EPC for the property at the time of marketing.

For commercial buildings, an Energy Performance Certificate must be provided each time a building is constructed, sold or let. This includes all types of buildings from small local shops, high street multiples and office buildings through to large industrial buildings and warehouses.

For Public Buildings of a certain size which are occupied by public authorities, Display Energy Certificates are a requirement showing the buildings operational rating and how efficiently the building is being used in terms of energy saving measures.

What does an Energy Performance Certificate look like?

The Energy Performance Certificate is broadly similar to the certificates found on many domestic appliances.

A Certificate gives the building an asset rating based on its energy efficiency, but does not take into account how the property is used by the occupiers. The Certificate will give the building an effieicency rating from A (high) to G (low). The Certificate will also show the building's environmental impact by indicating its carbon-dioxide emissions.

Commercial EPCs

From 4th January 2009 all commercial properties of 50 sq m gross internal area or larger require a Commercial EPC from the first day of marketing. Commercial Energy Performance Certificates are required for non-domestic buildings on construction, sale or rent.

It is the responsibility of the person selling or renting a building to have a valid Commercial EPC to show to prospective buyers and tenants. The Commercial Energy Performance Certificate must be given to the eventual buyer or tenant.

Commercial EPCs are not required before the construction of a building is completed. Nor are they required on the sale, rent or construction of:

  • Places of worship
  • Temporary buildings that will be used for less than 2 years
  • Stand-alone buildings with total useful floor space of less than 50 sq m
  • Industrial sites, workshops and non-residential agricultural buildings that don’t use a lot of energy some buildings that are due to be demolished
  • Listed buildings

The maximum penalty for non-compliance is currently £5,000, enforceable by Trading Standards. The penalty notice also includes the requirement to produce a valid Commercial Energy Performance Certificate.

The certificate is valid for ten years, or until a newer commercial EPC is prepared.

On construction: The constructor gives the Energy Performance Certificate and Recommendations Report to the purchaser on physical completion of the building and notifies Building Control, who will not issue the Certificate of Completion until the EPC is provided.

On sale/rent: As soon as the building is offered for sale/rent the seller/landlord must make an EPC available to prospective buyers/tenants. The Energy Performance Certificate may be for the whole building or individual units, and completion of a contract should not happen without it. Some multi-tenancy sale/rent scenarios are complex and you should seek advice from an accredited expert to determine whether an Energy Performance Certificate is required for the individual unit or the building as a whole.

On modification: The person undertaking the work is responsible for providing the Energy Performance Certificate and Recommendations Report to the client. They must then notify Building Control, who will not issue the Certificate of Completion until the EPC is provided.
