Commercial Energy Performance Certificates

How long is an Energy Performance Certificate valid for?

An Energy Performance Certificate is valid for 10 years.

If a property owner has improved the energy efficiency (e.g. by insulating the loft) he/she can then commission another Energy Performance Certificate, which may obtain a better ‘energy efficiency rating’.

Who needs an Energy Performance Certificate?

Property Sellers

Almost every property in England and Wales now requires an Energy Performance Certificate if it is marketed for sale. This is a legal requirement. A sale cannot occur without an Energy Performance Certificate in place.


Almost every rental property in England and Wales requires an Energy Performance Certificate from 1 October 2008, if the property is marketed to let. This is a legal requirement.

A tenant cannot 'legally' move in to the property until an Energy Performance Certificate has been produced, from this date.


New build properties are currently excluded if they were built under Regulation 17C of the Building Regulations (2006). This will be until the software needed to produce an Energy Performance Certificate (EPC) using SAP is available. This is likely to be in April 2008.

Penalties for Non-Compliance

On 8 February 2008 the Department for Communities and Local Government warned landlords that the Government is considering a 'fixed penalty charge' notice, which could be as much as £200 per dwelling, per day, for any landlord who fails to provide an up to date EPC to tenants

What does the certificate tell me?

The Certificate also tells you, on a scale of A-G, about the impact the home has on the environment. Better-rated homes should have less impact through carbon dioxide (CO2) emissions.

The average property in the UK is in bands D-E for both ratings. The certificate includes recommendations on ways to improve the home's energy efficiency to save you money and help the environment.
