   Awaiting decision

   Decision expected by 23 November 2026, 8 weeks from validation under the statutory target for most applications. Extensions of time are common and are agreed case by case.

   Hounslow took a median of 56 days over the applications it decided in the last year.

This application is with Hounslow for determination, against a statutory target of eight weeks. Over the last year Hounslow decided tree works applications in a median of 28 days. More in our guide to how long planning decisions take.

Applications for works to trees cover protected trees: consent under a tree preservation order, or six weeks notice for trees in a conservation area. More in our guide to planning application types.
