Hillingdon must plan for 2,339 homes a year
Hillingdon has to plan for 2,339 new homes a year, 11,695 over 5 years.
No brownfield cover figure for Hillingdon. 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 Hillingdon has no brownfield land.
Delivery
Over the three years to March 2025, Hillingdon delivered 2,163 of the 3,249 homes it was required to: 67%. The government's published consequence: the presumption in favour of sustainable development applies.
What is on the brownfield register
197 live sites covering 180 hectares, of which 23 have no planning permission yet. 197 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.
