Southampton: the market in figures

Southampton comes 73rd of the 135 areas covered and last of the 12 covered in the South East, with an average of £235,729. Compared with the South East (£379,953) that is 38% lower, though against the UK (£273,037) the gap narrows to 13.7%. The latest annual change is a gain of 0.8%, whereas the South East recorded a fall of 0.8%.

Since 2016 the average has risen 22.4%, or £43,145, from £192,584. The big moves came in 2021 (5.4%) and 2022 (10.2%), which took the price to its peak of £238,397. After that it barely shifted, losing 0.3% in 2023, then 1.3%, then 0.3% before the small recovery this year. Today's figure is within a whisker of the peak, and 2016 is the lowest year. The series by year reads £216,318 in 2021, £238,397 in 2022, £237,564 in 2023, £234,569 in 2024 and £233,902 in 2025, which is a plateau rather than a slide.

Types are spread widely. Flats sit at £153,068, with terraced homes at £251,650. A semi-detached home reaches £312,860 and a detached house £417,294. The step from a flat up to a detached house is £264,226, or 172.6%. First homes sold for £210,366 on average, 10.8% below the all-buyer average.

Taxes are light. Stamp Duty Land Tax for moving home is £2,215, or 0.9% of the price, and a first-time buyer pays £0. For an additional property the bill is £14,001, and the HM Land Registry fee is £150.

Every neighbour listed costs more. Eastleigh averages £312,753, 32.7% more than Southampton, and New Forest £384,564, 63.1% more. Test Valley, at £372,289, is 57.9% higher. Over in the South West, Bournemouth Christchurch and Poole averages £310,176 (31.6% more) and Wiltshire £328,102 (39.2% more). Southampton's sales volume was 2,633, taken from June 2025 to May 2026. Its position at the foot of the South East table means every other covered area in that region has a higher average than Southampton.
