Clapham Property Market: House Prices, Sold Data & Development Finance, Q3 2026 Review

Clapham: Lambeth family market with Victorian terraces, extensive back-garden development and strong buyer liquidity.

The Clapham property market recorded 3,895 residential sales in the 12 months to 30 June 2026, with a median sale price of £535,000. This places Clapham £55k above the Greater London county median of £480,000, and £250k above the approximate UK median of £285,000.

Prices in Clapham have been broadly stable, a year-on-year change of -1.8%. Within Greater London, Clapham ranks 24th by price out of 51 principal towns, and 7th by transaction volume.

On a quarterly view, Clapham median prices moved from £520,000 in Q1 2025 to £515,000 in Q2 2026, a change of -1.0% over 5 quarters.

Clapham shares a HM Land Registry reporting district with neighbouring towns, and the source data does not distinguish Clapham-specific sales from the wider district. The figures above reflect the whole shared district rather than Clapham alone.

Lambeth, the local planning authority covering Clapham, approved 21 residential planning applications and refused 18 in Q3 2026 (1 July to 30 September 2026), with 76 still awaiting a decision. That is an approval rate of 54%. A further 1 residential decision in the period has no recorded outcome in the source data and is not counted above. Planning figures come from local planning authority records compiled by Landstack, retrieved on 3 October 2026. Councils and Landstack can take several days to publish decisions, so decisions made in the final days of Q3 2026 may not all be included yet.

Schemes approved in Q3 2026, together with those still awaiting a decision, propose around 288 homes, an estimated £153.0m of development value at local sale prices. Treat the unit total as an upper bound, since an outline permission and its reserved-matters application both count.

Lambeth covers more than one town in Greater London, so these figures are authority-wide rather than specific to Clapham alone.

Property prices in Clapham vary significantly by type. The table below compares Clapham prices with Greater London county averages and UK national figures.

HM Land Registry has so far registered 105 new-build sales in Clapham for the past 12 months, 2.7% of registered transactions. New-build sales are typically registered 6 to 18 months after completion, so this understates current delivery and is not a completions figure.

On those registered sales, new builds in Clapham sold at a premium of 29.5% to existing stock.

Across the wider Greater London market, 1,006 new-build sales have registered so far. See our Greater London property market report for the full county picture.
