Compared like with like — same floor area, property type, build period and year of sale — a band B home sold for 4.6% less than a band D home (95% range −5.5% to −3.8%; national sample of 565,097 sales in bands B and D). 24% of band B sales are flats or maisonettes (band D: 10%). Data: HM Land Registry Price Paid to 30 September 2026 matched to the EPC register.

Like-for-like: regression of the log of price on “band X” against band D, log floor area, property type, build period (12 bands from the certificate) and year of sale, on the sales in bands X and D of a random national sample of 1,000,000 matched sales. The raw £/m² gap is larger because better-rated homes are newer and of different types. Across all bands, C-or-better against D-to-G like for like: +1.2% (+0.9% to +1.5%).
What drives the headline premium of EPC band B over D is the make-up of the band, not the letter on the Energy Performance Certificate (EPC): among sold homes there are more than twice as many flats in B as in D, and a square metre of a flat costs more than a square metre of a house. Like for like, with the same floor area, property type, build period and year of sale, B is cheaper than D. The data does not say why: the model knows nothing about condition, garden, parking or view.
Where band B is dearer than D, and where it is cheaper
A band B flat sold at £4,197 per m² against £3,667 for D; detached houses go the other way, £3,040 against £3,210. In the North East B holds £2,247 against £1,649; in the South East it falls behind: £3,952 against £4,010.
Is a band B rating good for your gas bill
The energy certificate for a band B house on gas gives 6,638 kWh a year, and DESNZ meter data for 2024 came in at about 103% of that figure: the calculation almost matches real life. Sales come from HM Land Registry from 2015 to 30 September 2026; the site's estimate is no substitute for a valuation of the house itself.
