An analysis of 18,151,094 domestic Energy Performance Certificates on the government register for England and Wales. The most common rating is band D and the average efficiency score is 67 out of 100. For homes a higher score is better. Data current to 2026-05-31.
These figures come from the government domestic EPC register for England and Wales. Whether you are selling, letting, or planning improvement works, the numbers below show where domestic stock sits today and how much room there is to improve.
Methodology note: figures are medians and averages drawn from the government domestic EPC register for England and Wales, current to 2026-05-31. Some fields are self-reported and may be incomplete, so treat figures as estimates.
The chart below shows the percentage of homes in each EPC band across England and Wales. For domestic properties the scale runs from A (most efficient, a score of 92 or more) down to G (least efficient), so a higher score is better. 51.1% of homes are rated C or above.
Bars are scaled to the most common band. Green = A to C, amber = D, red = E to G.
The average home could raise its energy-efficiency score by about 15 points, from 67 today to a potential 82. 66.9% of homes could improve by 10 points or more. The typical home emits roughly 3.5 tonnes of CO2 a year, which improvement works could cut to around 1.8 tonnes.
Every EPC we produce comes with tailored advice on the most cost-effective ways to lift the rating. If you need to reach a particular band, our MEES consultation service can map the least disruptive route there.
Under the Minimum Energy Efficiency Standards (MEES), a privately rented home must currently reach at least EPC E to be let (in force for all tenancies since April 2020). From 1 October 2030 the minimum rises to EPC C: every privately rented home in England and Wales will need an EPC C to be let, subject to a £10,000 per-property cost cap and limited exemptions. The government confirmed the EPC C standard in its January 2026 consultation response.
On today's data, 53.8% of privately rented homes are below EPC C and will need improvement to meet the 2030 standard, and 1.4% are rated F or G, which already cannot be let without an exemption. If you let a property, it is worth planning improvements well ahead of the deadline. We can carry out the EPC and advise on the most cost-effective route to a C.
Around 82.7% of homes are heated by mains gas, 12.5% by electricity and 3.3% by oil. As the grid decarbonises and heat pumps become more common, the heating mix is the single biggest lever on a home's running costs and carbon emissions.
About 61.9% of certificates are for houses and 27.4% for flats, with bungalows making up 8.4%. By tenure, 58.6% are owner-occupied, 22.3% privately rented and 19.1% social housing.
On the fabric, 73.5% of homes have insulated cavity walls and 89.9% are fully double-glazed or better, while 18.2% still have uninsulated solid walls. New builds make up about 13.6% of certificates, averaging a band B.
