   Awaiting decision

   Decision expected by 12 October 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 55 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 condition discharge and variation applications in a median of 56 days. More in our guide to how long planning decisions take.

This application deals with conditions on an existing permission, supplying the details a condition requires or asking to vary or remove one, without reopening the permission itself. More in our guide to planning application types.
