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

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

The Southwark property market recorded 3,283 residential sales in the 12 months to 31 May 2026, with a median sale price of £520,000. This places Southwark £35k above the Greater London county median of £485,000, and £235k above the approximate UK median of £285,000.

Prices in Southwark have recorded a moderate decline, a year-on-year change of -3.7%. Within Greater London, Southwark ranks 32th by price out of 51 principal towns, and 14th by transaction volume.

On a quarterly view, Southwark median prices moved from £548,000 in Q3 2024 to £525,000 in Q4 2025, a change of -4.2% over 5 quarters. The most recent quarter is excluded because HM Land Registry registrations for it are still incomplete.

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.

London Borough of Southwark, the local planning authority covering Southwark, approved 88 residential planning applications and refused 35 in the last 12 months, with 72 still awaiting a decision. That is an approval rate of 72%.

Those applications propose around 1,216 homes, an estimated £612.1m 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.

London Borough of 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 £1.70m, while flat properties are most accessible at £450,000. The £1.3m 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 154 new-build sales in Southwark for the past 12 months, 4.7% 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 Southwark sold at a discount of 4.3% to existing stock.

Across the wider Greater London market, 1,285 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 £520,000 and detached homes at £1.70m, lenders can assess scheme viability with confidence.

A typical development finance facility for a scheme in Southwark with a GDV of £1.70m would attract senior debt of approximately £1.10m 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 softened 3.7% year-on-year, experienced developers can still generate strong returns in Southwark by targeting well-located sites with clear demand drivers.
