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

Southwark: Inner South London borough with major regeneration at Elephant & Castle, Canada Water and the South Bank.

The Southwark property market recorded 3,194 residential sales in the 12 months to 30 June 2026, with a median sale price of £525,000. This places Southwark £45k above the Greater London county median of £480,000, and £240k above the approximate UK median of £285,000.

Prices in Southwark have been broadly stable, a year-on-year change of 0%. Within Greater London, Southwark ranks 31th by price out of 51 principal towns, and 14th by transaction volume.

On a quarterly view, Southwark median prices moved from £515,000 in Q1 2025 to £507,500 in Q2 2026, a change of -1.5% over 5 quarters.

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

The local planning authority for Southwark approved 24 residential planning applications and refused 10 in Q3 2026 (1 July to 30 September 2026), with 65 still awaiting a decision. That is an approval rate of 71%. 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 476 homes, an estimated £253.8m 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.

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

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

Detached homes in Southwark command £1.80m, while flat properties are most accessible at £450,000. The £1.4m spread between the most and least expensive types indicates a diverse market with opportunities across the development spectrum.

HM Land Registry has so far registered 37 new-build sales in Southwark for the past 12 months, 1.2% 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 Southwark sold at a premium of 2.6% 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.

For developers considering Southwark, the local market data translates directly into finance structuring. With a median value of £525,000 and detached homes at £1.80m, lenders can assess scheme viability with confidence.

A typical development finance facility for a scheme in Southwark with a GDV of £1.80m would attract senior debt of approximately £1.17m at 65% LTGDV. Mezzanine finance can stretch total borrowing to 85-90% of costs, while bridging loans enable rapid site acquisitions completing in as little as 5 working days.

While prices have remained flat year-on-year, experienced developers can still generate strong returns in Southwark by targeting well-located sites with clear demand drivers.
