What PlanWatch Is Tracking in Hillingdon

PlanWatch currently holds 447 Hillingdon planning records across 129 unique postcode locations, with tracked application dates from 2026-04-26 to 2026-08-25. The most common categories in this dataset are Householder (221), Full (159), Tree Works (51).

Use this page to start with a postcode search, then open the official council record for the decision notice, drawings, consultation deadline and any later conditions. That matters because a short application description rarely shows the details neighbours and buyers care about: side windows, roof forms, access, drainage, tree works, opening hours or amended plans.

Objecting to a Planning Application in Hillingdon

Hillingdon Council can only weigh objections that raise a material planning consideration. Personal disputes, loss of a view and property value are not material and are set aside. These are the grounds that do count, with what Hillingdon's planning officers will expect you to evidence for each.

Then write the objection letter, or check what counts as a material consideration before you start. Objections normally have to reach Hillingdon Council inside the 21-day consultation window.
