Planning appeals in London Borough of Hillingdon

When London Borough of Hillingdon refuses an application, or does not decide it in time, the applicant can appeal to the Planning Inspectorate. An appeal that is allowed is one the council lost. Raw rates are not comparable between councils, because some kinds of appeal are allowed far more often than others, so the Inspectorate's national rate for each kind is applied to this council's own caseload to give the rate its mix predicts.

London Borough of Hillingdon, raw rate

36.8%

of judged appeals were allowed, so the council's decision did not stand

Expected for this mix of appeals

30.5%

what the national rate for each kind of appeal predicts for this council's caseload

6.3 percentage points above expected. London Borough of Hillingdon's decisions are overturned more often than the national record for the same kinds of appeal predicts for its caseload.

2,416 appeals counted, 2,316 judged either way (853 allowed, 1,463 dismissed), 100 judged neither way. These are appeals decided 2016-07 to 2026-06.

By kind of appeal

Each kind of appeal against the national rate for the same kind. This is the comparison the headline is built from.

“Judged” counts appeals allowed or dismissed. The rest were withdrawn, invalid, split or unrecorded, and are counted but never treated as appeals the council won. A percentage is published only where at least 5 appeals were judged either way. Where it is not, the counts still are: a rate over one or two cases would claim a precision the sample cannot carry.

Money behind development in London Borough of Hillingdon

Developer contributions at London Borough of Hillingdon

London Borough of Hillingdon collects contributions from developers under planning obligations, but we do not yet hold its register in a form we can publish figures from. Only a minority of authorities publish one we can read, and this is not one of them, so we show nothing rather than a figure we cannot stand behind.

About London Borough of Hillingdon

London Borough of Hillingdon is a local planning authority responsible for processing planning applications within its area. Applications are submitted through the council's planning portal and cover a wide range of development types, from householder extensions and change of use to large-scale residential and commercial schemes.

SiteLens tracks the London Borough of Hillingdon planning register daily and enriches every new application automatically. Each is AI-classified by category and trade, given an estimated value band and a plain-English project brief, mapped, and checked against constraint flags like flood zones, conservation areas and green belt. Where an application names an agent, SiteLens shows the firm and matches companies to Companies House. Pro adds the applicant's name, the directors and company health behind each match, and the agent's direct email and phone where the council or firm publishes them, so you know who to speak to about the scheme.

You can also browse the council's own planning register on the official London Borough of Hillingdon planning portal.
