Southwark: the market in figures

Southwark is a place where the price level has slipped over a decade. Today's average is £569,160, against £587,400 in 2016, a change of minus 3.1% or £18,240 lost. The highest year was 2017 at £618,306 and the lowest 2021 at £537,423. Yearly moves swing both ways: up 5.3% (2017), down 5.5% (2018), down 8% (2021), up 10.9% (2022), and falls of 3% (2023), 1.7% (2025) and 2.1% (2026).

Against its surroundings, Southwark is 9th among the 135 areas and 8th out of 13 in London. It sits 2.7% over the London average of £554,430, which itself fell 2.2% over the year, and 108.5% over the UK mark of £273,037. The 2024 average of £591,428 and the 2025 average of £581,507 show the slope since the last recovery. Every yearly reading in the series falls between £537,423 and £618,306.

Property type creates the real spread. A flat averages £466,671, with terraced homes at £835,115. A semi-detached home reaches £1,226,452 and a detached house £1,727,364, a gap of £1,260,693 or 270.1% from the flat. The first-time buyer figure stands at £497,815, 12.5% under the all-buyer figure. Property type creates the real spread, as the figures show.

At this price, Stamp Duty Land Tax is £18,458 for a household moving home, which is 3.2% of the price. A first-time buyer owes the same £18,458, so at this price the first-time figure and the home-mover figure are identical. An additional property costs £46,916, and the HM Land Registry fee is £295.

Nearby, City of Westminster averages £887,206, which is 55.9% more than Southwark, though its prices fell 14.3% over the year. Lambeth is 5.1% cheaper at £540,198, Greenwich 18.7% cheaper at £462,868, Lewisham 14.5% cheaper at £486,416 and Tower Hamlets 21.3% cheaper at £447,950. The sales count is 2,746 across June 2025 to May 2026. Of the neighbours listed, only City of Westminster costs more than Southwark. Only the 2021 reading is lower than today's figure.
