Quick answer: there is not one perfectly comparable “UK average EPC” figure because EPC systems and datasets differ across the nations. For the latest ONS analysis of records in the ten years to March 2025, the median score was 69 (band C) in England and 68 (band D) in Wales. London’s median was 70, also band C.

What is the typical EPC rating in England?

ONS reports a median score of 69 for homes in England in its latest analysis. That is exactly the lower boundary of band C. The figure is based on properties with EPC records in the ten years to March 2025, not every home in the country.

What is the typical EPC rating in Wales?

The same ONS analysis gives Wales a median of 68, the top of band D. A one-point difference crosses the C/D band boundary, which is a useful reminder that letter bands can make small score differences look larger than they are.

What is the typical EPC rating in London?

London, the East of England and the South East each had a median score of 70 in the ONS analysis. Within London there is still substantial variation by property age, type and local area.

Why do older articles say D is the UK average?

Because the housing stock and the EPC dataset change over time. In the 2024 ONS release, England’s median was 68, band D. In the 2025 release it moved to 69, band C. Some websites also use “average” loosely when they mean the most common band, a mean score or an older dataset.

Can I compare my house with the national median?

Yes, but use it as context rather than a target. Property type and age matter. New homes tend to perform differently from older existing houses, and flats can behave differently from detached homes. Your own certificate’s potential rating and recommendations are usually more actionable than a national median.

What should homeowners take from the data?

If your property is around the C/D boundary, a small score difference can change the letter without transforming the building overnight. If it is much lower, the full recommendation list and building context matter more. For improvement planning, focus on evidence-led measures that suit the property.
