Market Overview: SW1A
Prices in SW1A span a notably wide range, from £406k at the lower end to £118.67m at the top of the 9-sale sample — a signal that the local housing stock is mixed rather than homogeneous. The £406k–£118.67m range is unusually wide, so the median understates what a buyer will see at either end of the market.
Flats were the most common transaction type, representing 67% of sales, while other property types accounted for 33%. That flats-heavy composition is typical of central and inner-London postcodes where purpose-built blocks and converted period buildings dominate.
For buyers and sellers in SW1A 1DA, the wide dispersion means averages are a weak guide — comparable sales matched on property type, floor area and condition will produce a far tighter estimate. On the rental side, the estimated gross yield on a median-priced property here is around 2.7%, based on ONS regional rents.
