Land Registry sales in N21 matched to the home's energy certificate, the sales every figure on this page is computed from.
N21's Location Premium is -16.0%: in CityDataLab's factor model fitted to July 2026, an otherwise identical home (same size, type, age and energy rating) is priced 16.0% less per square metre in N21 than in a district at the average London district price level.
The model measures a district's location by its median price per m² over the previous twelve months, in standard deviations across London's postcode districts. N21 sits 0.50 standard deviations below the average district. The Location Premium is the part of a home's price per m² the model puts down to that location; the rest depends on the home itself and on the market as a whole.

Prices are HM Land Registry price paid data for homes sold in N21, each matched by address to its MHCLG energy performance certificate for the floor area. Price per m² is the price paid divided by that floor area; medians are taken over the twelve months to the month shown, and districts, their postcode area and London are always compared over the same twelve months. Sales without a matched certificate, and non-residential and "other" sales, are not counted.
