What is an EPC?
When a home is built, sold or rented in the UK, it needs an Energy Performance Certicate (EPC). This shows you how much a building will cost to heat and light, what its carbon dioxide emissions are likely to be and what improvements you can make to improve its energy efficiency.
An EPC rates a property in bands from A (most efficient) to G (least efficient) and is valid for 10 years from the date it's issued.
EPC rating bands
Using the government's Standard Assesssment Procedure (SAP) your home will be given a numerical score from 1-100 SAP points. These scores are divided into bands as follows:
- EPC rating A = 92-100 SAP points (most efficient)
- EPC rating B = 81-91 SAP points
- EPC rating C = 69-80 SAP points
- EPC rating D = 55-68 SAP points
- EPC rating E = 39-54 SAP points
- EPC rating F = 21-38 SAP points
- EPC rating G = 1-20 SAP points (least efficient)
On the right hand side of each chart, you can see the current rating based on the existing energy performance of your property next to the potential rating you could achieve by making the improvements recommended in your EPC.
Improving your home's EPC
Making your home more energy efficient won't just make it a warmer, more comfortable place to live, it can also improve its value. Here are some of the ways you can improve your score:
You can find out more on improving your home's energy performance (including the subsidies available to help with the costs of these improvements) by visiting our energy efficiency pages.
As well as showing your home's energy performance score, the EPC also includes a list of recommended improvements along with the estimated cost saving.
