Does a C-or-better EPC sell for more in BA22 9 (Somerset)?
No measurable EPC premium here. In postcode sector BA22 9 (Somerset), comparing like with like — same floor area, property type, build period and year of sale — the difference is +5.8% (95% range −0.6% to +12.6%): the EPC band itself is not reflected in sale prices here. The raw gap is bigger: C+ homes sold for 22% more per square metre than D–G homes (median £3,313 vs £2,712, 828 sales 2015–2026), mostly because they are different homes. Across England and Wales the like-for-like figure is +1.2%. Data: HM Land Registry Price Paid to 30 September 2026 matched to the EPC register.
From the raw gap to like-for-like
The homes are not alike: C+ homes here have a median floor area of 99 m² against 97 m² for D–G; the most common build period is 2012 onwards for C+ and before 1900 for D–G; 69% of C+ and 68% of D–G sales are detached or semi-detached houses.
| Comparing C+ with D–G homes… | Difference | 95% range |
|---|---|---|
| Raw gap per m² (medians) | +22% | — |
| Whole price, nothing held equal | +13.5% | +0.1% to +28.7% |
| Same floor area | +14.9% | +8.1% to +22.1% |
| + same property type | +14.0% | +8.4% to +19.8% |
| + same build period | +7.5% | −0.3% to +15.9% |
| + same year of sale | +5.8% | −0.6% to +12.6% |
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.

Average gas use in BA22 9 (2024): meters vs certificates
A rough comparison: the certificate figure is an upper-bound estimate (primary energy including lighting, converted with one factor), so treat the share as an order of magnitude.
| Postcodes with published gas data (5+ meters) | 1 (7 meters) |
|---|---|
| Median gas use per meter (median of postcodes) | 16,295 kWh |
| Gas-heated homes with an EPC | 22 |
| Energy implied by their certificates (median) | 17,204 kWh |
| Metered gas as a share of the certificate figure (median of 1 postcodes) | 86% (middle half 86%–86%) |
Certificate energy = primary energy per m² × floor area ÷ 1.13, for homes whose latest certificate shows mains gas heating; it also covers lighting and other uses, so it is an upper bound for gas. DESNZ gas is weather-corrected and covers all meters in the postcode, with or without a certificate.
828 of 977 house and flat sales in the sector since 2015 (85%) were matched to a certificate.
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.
- Individual sales and addresses are not shown.
