   Awaiting decision

   Decision expected by 17 November 2026, 8 weeks from validation under the statutory target for most applications. Extensions of time are common and are agreed case by case.

   East Suffolk took a median of 53 days over the applications it decided in the last year.

This application is with East Suffolk for determination, against a statutory target of eight weeks. Over the last year East Suffolk decided outline applications in a median of 18 days. More in our guide to how long planning decisions take.

An outline application tests the principle of developing a site, holding back details such as appearance and landscaping as reserved matters for later approval. More in our guide to planning application types.
