Across England and Wales, homes rated EPC C or better sold for 9% more per square metre than homes rated D–G (median £3,041 vs £2,801; 9,109,807 sales since 2015 matched to a certificate). Compared like with like — same floor area, property type, build period and year of sale — the premium shrinks to +1.2% (95% range +0.9% to +1.5%): most of the raw gap comes from which homes are rated C+ (newer, different sizes and types), not from the rating itself. Of 6,882 postcode sectors with enough sales for a reliable figure, 1,811 show a like-for-like difference distinguishable from zero (about 344 would by chance alone). Data: HM Land Registry Price Paid to 30 September 2026, EPC register November 2026.

From the raw gap to like-for-like
Homes rated C or better are mostly newer and differ in size and type from D–G homes. Taking those differences out one by one:
Raw gap per m²+8.5%
Whole price+8.0%
Same floor area+10.7%
+ same property type+5.5%
+ same build period+4.7%
+ same year of sale+1.2%

The first row compares median prices per m²; the second compares whole prices; each later row adds one more thing that must be equal, ending with the like-for-like premium (regression of log price; build period from the certificate, 12 bands). The raw gap per m² and the whole-price gap differ because C+ and D–G homes differ in size.
Of 6,882 postcode sectors with enough sales for a reliable figure, 1,305 show a like-for-like premium for C+ that is distinguishable from zero and 506 a discount; about 344 would look different by chance alone, even with no real effect anywhere. The rest show no measurable difference.
Barely. Compare homes of the same floor area, type, build period and year of sale, and the Energy Performance Certificate (EPC) band moves the price by a few percent, not tens of percent. The raw gap comes from the C-and-above homes themselves: they are newer, of a different size and type, and buyers pay for that.
How the gap shrinks, and where it looks different
In HM Land Registry sales from January 2015 to 30 September 2026, a square metre in C-and-above homes cost £3,041, against £2,801 for D–G. Equalise those four conditions and what remains is +1.2%. In London it comes out at +2.1%, in Wales +2.0%, while the North East and South East show a discount, even though the raw gap in the North East was +24%.
Bands one by one and the gas meter
Each band against D is broken down in the A to G scale. Meter data for 2024 showed the median gas-heated home using 61% of the consumption stated on its certificate. You will not find your own home's certificate here: the search runs by postcode sector or postcode district. The site is no substitute for an assessment of your home.

Gas: what meters show vs what certificates say (2024)
In 981,179 postcodes with published gas data and at least three gas-heated homes with a certificate, the median home used 61% of the gas its certificate implies (10,092 kWh metered vs 16,715 kWh). The worse the band, the bigger the overstatement (postcodes where at least 60% of certificated gas homes share the band):

A rough comparison: postcode gas medians cover all homes, certificate energy is an upper bound for gas. It shows the order of magnitude: savings promised for upgrading a D–G home are usually smaller in practice.
How this is calculated
Every standard sale (HM Land Registry Price Paid, category A) since January 2015 is matched to the latest energy certificate of the same address (postcode + house number or name + flat) lodged from 10 years before to 3 months after the sale; sales with no certificate or an ambiguous match are left out. Across England and Wales 92% of sales match.
Price per m² uses the certificate's total floor area (15–1,000 m²).
Like-for-like premium: regression of the log of price on “C or better”, log floor area, property type, the certificate's build period and the year of sale. The 95% range shows how precise the estimate is; when it includes zero, the data cannot tell the premium apart from none.
Caveats
The band is the one on the certificate before the sale; certificates are a median 0.8 years old at the sale, but a quarter are over 4 years old and some homes were improved since.
Condition, garden, parking, views and the exact position within the sector are not known; a premium could hide in them, or they could hide one.
