Market Overview: SL1
Turnover in SL1 has been high, with 340 residential sales logged by HM Land Registry in the last twelve months — enough volume that the median figure is reasonably representative. Individual sales ranged from £100k to £11.60m, which is a normal spread for a postcode of this size.
No single property type dominates — flats led with 32% but the mix is diverse, while terraced houses accounted for 24% and semi-detached houses accounted for 29%.
The twelve-month trend is upward: comparing the first half of the window with the second, the median shifted by roughly +4.3%. Monthly volume was fairly consistent, giving the trend line a reliable shape.
Liquidity in SL1 1AA is healthy: the high sale count makes it easier to benchmark a specific property against genuinely recent comparables rather than extrapolating from older deals. On the rental side, the estimated gross yield on a median-priced property here is around 3.8%, based on ONS regional rents.
