Green premium

Energy-efficient houses (EPC A-C) vs less efficient houses (EPC D-G) sold in SO51 in the last 5 years, compared £ per m².

-2.5%

EPC A-C houses here sell for 2.5% less per m² than EPC D-G houses, comparing homes of a similar age.

£4,528/m² (766 sales) vs £4,566/m² (698 sales)

The unadjusted comparison shows -0.8% — different because houses of different EPC ratings here also tend to be different ages, and older homes carry their own price premium or discount that has nothing to do with energy efficiency. The age-adjusted figure above compares only homes built in the same era.

For context, 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 — a projection assumption applied equally to every dwelling type, not a local measurement. Panakaduwa, Figshare 2026 (CC BY 4.0). The -2.5% above is what SO51 buyers actually paid.
