An Energy Performance Certificate (EPC) measures the energy efficiency of a property on a scale of A to G.

Energy Performance Certificates were introduced in England and Wales in 2007 and are a legal requirement for a building to be sold or let.

An Energy Performance Certificate (EPC) is valid for 10 years.

The most efficient houses which should have the lowest fuel bills are rated in band A. The EPC also tells you on a scale of A to G, about the impact the home has on the environment. Higher rated homes should have less impact through Carbon Dioxide (CO2) emissions.

The average property in the UK is ranked in bands D to E. The EPC also includes recommendations on ways to improve the home's energy efficiency to save you money and help the environment.

In April 2018 Minimum Energy Efficiency Standards introduced made it a legal requirement for all privately owned properties to have an EPC rating of at least an E before being sold or let. The legislation applies to all domestic properties, although there are some exemptions, for example if a property is classes as a listed building.

Owners failing to make the necessary changes will be subject to the appropriate fines up to £5,000 for domestic dwellings.

When conducting the EPC survey, the energy assessor will need to access all rooms as well as the loft. They are also required to inspect heating systems and controls, take measurements and take photographs of all key data included in the survey. The survey is non invasive and a visual inspection is all that is required.

Energy assessors input this information into the software , to produce an Energy Performance Certificate (EPC) which is lodged to the central register.
