The EPC Premium: A-rated UK homes sell for 5% more

EPC ratings exist on paper. Until they show up in prices, the rating is a piece of advice the market is free to ignore. So we asked the straightforward question: for two near-identical homes on the same street, does the one with the better EPC sell for more? We joined HM Land Registry sold-price records to the EPC register, took the most recent rating for every property, and looked at price per square metre band by band, controlling for location.

Controlling for location matters. A-rated homes are not scattered evenly across the country; they cluster in newer developments, often in particular regions. Comparing raw prices would measure where the homes are, not how efficient they are. So instead, for every sale we asked: how does its price per square metre compare with the median for its own outcode? The result is the premium (or discount) that survives once area effects are stripped out.

A-rated and B-rated homes sit clearly above the local market. C and D hover at it. E and G sit below it. The exception is F, where the effect comes out near zero — we will come back to that.

For houses specifically (excluding flats, which add noise because their EPCs and price records do not always pair cleanly), the relationship is even cleaner: A +5.0%, B +4.4%, E -2.9%, G -3.7%. The gap between an A-rated house and a G-rated house, after location is removed, is roughly nine percentage points of price per square metre. On a £270,000 UK home (the rough national median), that is around £20,000 to £25,000 of sale value.

In the raw national numbers, F-rated homes have an unusually high median £/m² for their band. Look only at the headline figure and you might conclude that an F rating somehow commands a premium — which is exactly the kind of conclusion that location-controlled analysis exists to prevent.

What is actually happening: F-rated homes are disproportionately older and larger period properties, often in expensive areas (Victorian houses, country properties, listed buildings). Their high raw £/m² reflects the streets they are on, not the rating. Once each sale is compared with its own outcode, the F-band effect collapses to roughly zero. The character premium for period houses is real, but it is being captured by location, not by the EPC rating.

The number to remember is roughly five percent. The price difference between an A-rated and a typical (D-rated) home, attributable to the rating itself rather than to where the home is, comes out at about that, with the gap widening to around eight to nine points at the extremes. On the typical UK home, that is a five-figure number, comparable to other decisions homeowners spend real money on (a new kitchen, an extension footprint).

The implication runs in both directions. For an owner with an A or B rating, the efficiency is showing up in the market price — there is no need to discount the rating as an SEO factor that nobody pays attention to. For an owner sitting on an E, F or G, an upgrade is not only a moral or running-cost calculation; it has a measurable resale value attached. And for buyers, the price you are quoted for an A-rated home is doing some real work on the cost-of-ownership side.
