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 SL1 over 12 months — the two measure different things and can differ.
Area rent and gross yield
| Type | Area rent / month | Gross yield |
|---|---|---|
| Detached | £2,151 | 3.9% |
| Semi-detached | £1,728 | 4.5% |
| Terraced | £1,553 | 4.7% |

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.
