Green premium in FY8
Energy-efficient houses here sell for +1.6% per m² more than inefficient houses — age-adjusted across 2,364 sales.
In FY8, EPC-rated A-C houses sold for a median £2,817/m² against £2,679/m² for D-G-rated houses — a difference of +1.6% per square metre, comparing only homes built in the same construction era (4 era bands with enough sales on both sides). Figures cover HM Land Registry sales in the last 5 years matched to EPC certificates by address.
Why age-adjusted, not raw
A city-wide comparison of every efficient sale against every inefficient one is misleading on its own: older homes carry their own price premium or discount that has nothing to do with energy efficiency, and EPC ratings correlate strongly with build era. A Victorian terrace rated D can still out-price a 2005-built terrace rated B, simply because of where and when it was built — not because being less efficient made it more valuable.

How this compares to national projections
A national dataset published July 2026 models a uniform England-wide retrofit premium of +5.8% (medium retrofit) to +10.9% (predicted retrofit) by 2050 — Panakaduwa, Figshare 2026 (CC BY 4.0). That figure is a single projection assumption applied equally to every English dwelling type — not a measurement, and not specific to FY8. The +1.6% above is what FY8 buyers actually paid, today, and — like most outcodes we've measured — it doesn't match the national assumption. The premium varies by area and by construction era in ways a single national number can't capture.
