   Awaiting decision

   Decision expected by 4 November 2026, 8 weeks from validation under the statutory target for most applications. Extensions of time are common and are agreed case by case.

   Haringey took a median of 55 days over the applications it decided in the last year.

This application is with Haringey for determination, against a statutory target of eight weeks. Over the last year Haringey decided amendment applications in a median of 50 days. More in our guide to how long planning decisions take.

An amendment application makes limited changes to a permission that already exists; anything beyond modest adjustment needs a fresh application. More in our guide to planning application types.
