Hillingdon in West London includes Uxbridge, Hayes, and Ruislip. About 42.1% of the borough is Green Belt, framing suburban development and limiting urban expansion. Known for historic buildings, parks, and Heathrow-adjacent communities, planning focuses on extensions, conversions, and sensitive residential schemes.
In the last year Hillingdon decided 1,703 applications which is well above the national average of 988. The approval rate was 84% (roughly equal to the national average of 88%) and 57% of applications were decided on time, (on par with the national average of 59%). Stats updated March 2026 from gov. sources. See how Hillingdon performs relative to other LPAs in our LPA hub.
42.1% of Hillingdon is within the Green Belt and proposals in these areas can be subject to very high levels of scrutiny.
Development within the Green Belt surrounding London is highly sensitive and politically contentious. The Green Belt around Uxbridge and Harefield limits development to protect open countryside and prevent urban sprawl from Greater London.
