   Awaiting decision

   Decision expected by 27 May 2026, 8 weeks from validation under the statutory target for most applications. Extensions of time are common and are agreed case by case.

   Oxford took a median of 47 days over the applications it decided in the last year.

This application is with Oxford for determination, against a statutory target of eight weeks. Over the last year Oxford decided prior approval applications in a median of 37 days. More in our guide to how long planning decisions take.

Prior approval applies where permitted development rights already grant the principle of the work, leaving the council only the specific matters the rules name, commonly within 56 days. More in our guide to planning application types.
