   Awaiting decision

   Decision expected by 26 November 2026, 8 weeks from validation under the statutory target for most applications. Extensions of time are common and are agreed case by case.

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

This application is with Cardiff for determination, against a statutory target of eight weeks. Over the last year Cardiff decided advertisement consent applications in a median of 38 days. More in our guide to how long planning decisions take.

Advertisement consent is judged on two things only: amenity and public safety, not competition or other planning considerations. More in our guide to planning application types.
