Westminster must plan for 4,151 homes a year
Westminster has to plan for 4,151 new homes a year, 20,755 over 5 years.
No brownfield cover figure for Westminster. Only 0% of the sites on this council's brownfield register give a housing estimate, so its capacity cannot be totalled. We publish the cover figure only where at least 80% do.
That is a gap in the register, not evidence that Westminster has no brownfield land.
Delivery
Over the three years to March 2025, Westminster delivered 3,552 of the 2,955 homes it was required to: 120%. The government's published consequence: no consequence.
What is on the brownfield register
272 live sites covering 93 hectares, of which 48 have no planning permission yet. 272 of them give no housing estimate.
A council short of land has to find more, and the 17 August 2026 planning framework widened what counts as grey belt. This page describes the council's position. It does not say whether any particular piece of land would get permission.
