Does a C-or-better EPC sell for more in TN3 8 (Tunbridge Wells)?
Too few comparable sales here for a reliable like-for-like figure. In postcode sector TN3 8 (Tunbridge Wells), comparing like with like — same floor area, property type, build period and year of sale — there are too few comparable sales in each group for a reliable figure; for district TN3 as a whole the like-for-like difference is +1.4% (95% range −1.8% to +4.7%). The raw gap is different: C+ homes sold for 2% more per square metre than D–G homes (median £4,423 vs £4,342, 174 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 108 m² against 106 m² for D–G; the most common build period is 2003–2006 for C+ and before 1900 for D–G; 56% of C+ and 73% of D–G sales are detached or semi-detached houses.
This sector has fewer than 150 matched sales, fewer than 30 in one group, or an estimate too imprecise or implausibly large to trust, so the like-for-like comparison is not shown; the district figure is above.

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.
