What PlanWatch Is Tracking in Hillingdon

PlanWatch currently holds 1,072 Hillingdon planning records across 413 unique postcode locations, with tracked application dates from 2026-04-26 to 2026-10-19. The most common categories in this dataset are Householder (513), Full (424), Tree Works (79).

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.

Check approved drawings

Match drawing numbers and revision letters before relying on a plan.

Read conditions

Find conditions that control privacy, noise, drainage, materials or timing.

Write a useful objection

Keep comments factual, specific and tied to material planning issues.
