## The same life, one postcode cheaper

Mayfair (W1J 8) and SW1A 2 sit about 1.31 km apart, share the same dominant housing (flats/maisonettes, typically built around 2000), comparable good-school catchments and the same level of station access. Yet an equivalent home works out roughly 37% (about £916,380 on a 90 m² property) cheaper in SW1A 2. On the measures that move price they are near-identical; the gap is mostly the premium attached to the better-known name.

## How we worked this out

Postcode sectors (e.g. N10 3) compared on estimated £/m² of floor space. A pair is only called a 'twin' when the two sectors share the dominant property type, build era (±30y), good-school catchment provision, station access, deprivation/tenure, education, age and home size, so the price gap reflects a name premium, not a different kind of area. Estimates, not valuations; aggregated to sector, never address-level.
