Sold house prices in SN1 (Swindon)

407 standard residential sales registered with HM Land Registry for completions from 1 August 2025 to 31 July 2026 (our data runs to 28 August 2026). The newest month, August 2026, is left out: HM Land Registry is still adding sales to it. Earlier recent months can still grow a little in later releases.

Median = the middle sale price. Middle 50% = from the 25th to the 75th percentile. The 95% interval shows how far the median could move with a different set of sales; a wide interval means few or very varied sales. Types with fewer than 20 sales show no price.

The UK House Price Index (HM Land Registry, calculated by the ONS) is a modelled average for the whole local authority, adjusted for the mix of homes sold and smoothed over 3 months; the latest months are provisional and are revised. Our median above is the middle actual sale in SN1 over 12 months — the two measure different things and can differ.

Area rent and gross yield

TypeArea rent / monthGross yield
Detached£1,5144.8%
Semi-detached£1,1744.5%
Terraced£1,0665.4%
Flat / maisonette£9077.5%

Area rent = ONS Price Index of Private Rents for the local authority of each sale (August 2026): the average rent of existing tenancies of that property type — an area baseline, not the rent a particular home would let for. Gross yield = area rent × 12 ÷ median price, before costs, tax and voids.
