Does a C-or-better EPC sell for more in NG8 4 (Nottingham)?
A small premium for a better EPC here. In postcode sector NG8 4 (Nottingham), comparing like with like — same floor area, property type, build period and year of sale — homes rated C or better sold for 7.8% more (95% range +2.4% to +13.6%). The raw gap is bigger: C+ homes sold for 24% more per square metre than D–G homes (median £1,992 vs £1,600, 794 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 83 m² against 83 m² for D–G; both groups are most often built in 1950–1966; 54% of C+ and 91% of D–G sales are detached or semi-detached houses.
| Comparing C+ with D–G homes… | Difference | 95% range |
|---|---|---|
| Raw gap per m² (medians) | +24% | — |
| Whole price, nothing held equal | +16.2% | +9.7% to +23.0% |
| Same floor area | +21.2% | +15.4% to +27.2% |
| + same property type | +28.1% | +21.4% to +35.2% |
| + same build period | +19.8% | +12.5% to +27.6% |
| + same year of sale | +7.8% | +2.4% to +13.6% |
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 NG8 4 (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) | 148 (3,251 meters) |
|---|---|
| Median gas use per meter (median of postcodes) | 10,184 kWh |
| Gas-heated homes with an EPC | 2,688 |
| Energy implied by their certificates (median) | 14,050 kWh |
| Metered gas as a share of the certificate figure (median of 144 postcodes) | 66% (middle half 60%–74%) |
Certificates by band imply: B 6,579 kWh (277 homes) · C 12,851 kWh (1,392 homes) · D 19,007 kWh (804 homes) · E 27,236 kWh (196 homes) · F 44,082 kWh (13 homes). Across England and Wales, real use is much closer to the certificate for A–C homes than for D–G homes, so the saving an upgrade promises is usually smaller than the certificate suggests.
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.
794 of 838 house and flat sales in the sector since 2015 (95%) 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.
