About the area
Who we serve in South West London
South West London covers Wandsworth, Richmond upon Thames, and Kingston upon Thames. This is one of the most consistent family home markets in London, dominated by Victorian and Edwardian houses in the inner areas (Wandsworth, Battersea, Balham) and higher-value period stock around Richmond, Barnes, Kew, and Putney. The Thames runs through the patch, bringing riverside property and its specific considerations.

Housing stock
What to expect
Victorian villas dominating Wandsworth, Battersea, Putney, and Barnes. Georgian and early Victorian stock around Richmond, Twickenham, and Kew. Period conversions and purpose-built mansion blocks along the river. 1930s suburban and Tudor-style semis in Kingston, Surbiton, and New Malden. Significant new-build along the Nine Elms and Battersea Power Station corridor.
Market context
Current market
SW London is a premium family home market with historically strong demand, though values have cooled from 2014 peaks. Richmond and Barnes remain two of the most consistent markets in London. The Battersea Power Station regeneration has added significant new supply. Proximity to good state schools drives buyer behaviour heavily in this area.
Market data
South West London in 2026
South West London remains one of the capital's premium markets, anchored by Victorian villas, riverside family homes, and extensive period conversions through Putney, Wandsworth, Richmond, and Clapham. Values have corrected over the past year: Wandsworth averaged around £672,000 in early 2026, down close to 5%, with flats falling faster than houses. Well-connected outer boroughs and family houses have proved more resilient than flat-heavy postcodes nearer central London. A notable share of listings has been withdrawn unsold after overpricing, so independent valuation advice carries particular weight here, and buyers of larger period homes should budget for the maintenance such stock demands. (Figures from HM Land Registry and ONS data, early 2026.)
