The Energy Performance Certificate (EPC) scale runs from A to G, but the market lives in the middle. Of the 9,109,807 sales in England and Wales from 2015 to 30 September 2026, most landed on D and C, and the ends of the scale are almost empty. In money terms, the band only matters at the bottom.
What a band is worth against D
Like for like, at the same floor area, type, build period and year of sale, C costs 1.0% more than D, the rare A (0.5% of sales) 2.2% more, while B (16.5% of sales) is actually 4.6% cheaper; the data do not show why, see band B. At the bottom the scale breaks down: F loses 7.7%, and G as much as 17.4%.
The band below which you cannot let
Under the Minimum Energy Efficiency Standard (MEES), in the GOV.UK guidance dated 5 May 2026, housing below E cannot be let without an exemption: the owner of an F or G either lifts the property to E or registers an exemption. The rating on this site does not replace an assessment of the home itself.
