As charming as a period property or older home can be, they often cost more to heat than a new build.
As energy prices rise that can be a worry – we’re all expecting to spend more on gas and electricity in our homes this year. So, it’s a good idea to see where you could reduce your household energy bills.
The Energy Performance Certificate (EPC) rating is a scale that shows how energy efficient your home is, from A to G. The top rating is A and the lowest is G.
Most houses built in the last ten years are rated B or higher. The average rating for all homes in England and Wales is D. And for the 4.2 million homes built before 1900, the average EPC rating is only E.
Source: Property age and energy rating data are taken from ONS Energy Efficiency figures for England and Wales. February 2022.

Most of our homes fall short of the average EPC rating of C, apart from flats which usually achieve a rating of C or above. Around 15 million or 60% of homes in the UK need energy efficiency improvements to meet a minimum EPC rating of C.
Source: The analysis is based on the average energy efficiency of buildings in Local Authority District (LAD) in a given year between 2015 and 2019 and it’s estimated impact on average house prices in the same LAD the year after.
On average moving up one EPC rating band could save around £250 per year. Homes with the highest EPC rating A can be worth up to £40,000 more compared to the lowest G rating. This is sometimes called the Green Home Premium.
Cost savings estimated on a 4 bedroom detached house located in the North of England with a South East facing garden and budget of £10,000.

Changing your EPC rating from G to F could lead to an average price increase of £9,954 or 3.8%.
Changing your EPC rating from F to E could lead to an average price increase of £7,584 or 2.9%.
Changing your EPC rating from E to D could lead to an average price increase of £6,162 or 2.4%.
Changing your EPC rating from D to C could lead to an average price increase of £5,214 or 2.0%.
Changing your EPC rating from C to B could lead to an average price increase of £5,214 or 2.0%.
Changing your EPC rating from B to A could lead to an average price increase of £4,740 or 1.8%.
