EPC rating and sold prices in CH46 (Wirral)
In postcode district CH46 (Wirral), homes rated EPC C or better sold for 11% more per square metre than D–G homes (median £2,151 vs £1,933, 3,933 sales). Like for like — same size, type, build period and year — the difference is +1.5% (95% range 0.0% to +3.1%): the EPC band itself is not reflected in sale prices here. 3 of 8 sectors with enough sales show a difference distinguishable from zero. Data: HM Land Registry to 30 September 2026, 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 87 m² for D–G; the most common build period is 2012 onwards for C+ and 1930–1949 for D–G; 71% of C+ and 82% of D–G sales are detached or semi-detached houses.
| Comparing C+ with D–G homes… | Difference | 95% range |
|---|---|---|
| Raw gap per m² (medians) | +11% | — |
| Whole price, nothing held equal | +7.7% | +5.0% to +10.4% |
| Same floor area | +10.7% | +8.5% to +13.1% |
| + same property type | +13.3% | +11.4% to +15.2% |
| + same build period | +6.4% | +4.3% to +8.5% |
| + same year of sale | +1.5% | 0.0% to +3.1% |
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.

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.
