What is an EPC?

An Energy Performance Certificate (EPC) measures the energy efficiency of a property on a scale of A-G. Energy Performance Certificates were introduced in England and Wales in 2007 and are a legal requirement for a building to be sold, let or constructed. Once obtained, an EPC rating is valid for 10 years.

The most efficient homes – which should have the lowest fuel bills – are in band A. An EPC 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. An Energy Performance Certificate includes recommendations on ways to improve the home’s energy efficiency to save you money and help the environment. EPC’s apply also to commercial buildings and are rated only by Carbon Dioxide emission ratings on a scale of A-G.

An EPC is required whenever a building is sold, constructed or rented out, and provides a breakdown of a home’s energy efficiency. This does not include your usage of energy as an occupant, but looks at the energy performance of the property alone.

Why Do I Need an EPC Rating Check?

It is a legal requirement to have a valid Energy Performance Certificate (EPC) when a building is sold, rented or constructed.

Your property’s Energy Performance Certificate needs to be available to potential buyers as soon as you start to market your property for sale or rent. This will inform people how energy efficient the property is, including any potential savings on fuel payments.

You must get an approved/accredited EPC assessor to carry out the checks and produce the EPC report, which provides information about a property’s energy use and typical energy costs.

How Much Is an EPC?

Energy Performance Certificate costs range depending on the size and type of the building. EPC prices start from £40 +VAT for a flat and £45 +VAT for a house. The full list is below.

SAP Assessment Calculations Cost

A standard assessment procedure (SAP) is required during the construction of a new build as the SAP calculation determines the EPC. Building regulations demand this document before the build goes ahead.

Our domestic energy assessor can do a SAP assessment for an on-construction EPC. The SAP calculations cost differs on the building size and whether it’s a house or flat. Prices are below.

Minimum Energy Efficiency Standards (MEES) Legislation

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 they are sold or let. The legislation applies to both domestic and commercial properties, although there are some exemptions, for example if a property is a listed building.

Those who fail to make the necessary changes will be subject to the appropriate fines: up to £5,000 for domestic dwellings and up to £150,000 for non-domestic properties.

What Is Involved in an EPC Rating Check?

If you require an EPC rating check, you will need an accredited energy assessor to conduct an energy assessment.

The EPC 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. You can ask the assessor how long they expect to take to complete the process, as the time varies between properties.

EPC assessors can input this information on site or at home to produce an Energy Performance Certificate which is lodged to the central register.

How Do I Get a Copy of an EPC?

If you have the report reference number (RRN) or an address, you can easily retrieve an EPC certificate by going to the appropriate register.
