Prices are HM Land Registry price paid data for homes sold in UB9, 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.
