All homes that are on sale or for rent must have an Energy Performance Certificate (EPC) showing how energy efficient the property is.

EPCs were introduced in 2007 and are valid for 10 years from the date of issue. It is a legal requirement to have one if you intend to sell your home or rent a property. 

What is an EPC rating and what does it mean?

Properties are rated on their energy efficiency on a scale of A to G.

The properties that are rated A are the most energy-efficient, whilst properties at the opposite end of the scale are rated G as they will be the least energy efficient which means fuel bills will be more expensive. 

What other information does the EPC show?

The EPC will also state the estimated energy costs of the property over a period of three years, which is subsequently divided into lighting, heating and hot water costs. It also lists what your potential costs could be if you made the property more energy-efficient. The certificate will provide you with a list of suggested improvements you can take to make your home more efficient.

How to find out what your EPC rating is

If you are unsure what the EPC rating on a property is, you can search the EPC register. If your property does not have an EPC you will need to appoint an accredited assessor to visit your property and produce a certificate. 

How is an EPC rating calculated?

An assessor that visits your property will calculate your EPC rating by examining features such as windows, roof insulation and lighting. Points are scored for each energy-efficient measure in your home. Once the assessor has completed the inspection, they will use software to deduce the energy rating for the property and produce the certificate. 

How much does it cost to get an EPC rating?

The cost of an EPC will vary depending on where you are in the country and the size of your property.  These start from around £35 and go up to £120 or more.
