   Awaiting decision

   Decision expected by 31 July 2026, 8 weeks from validation under the statutory target for most applications. Extensions of time are common and are agreed case by case.

The published feed does not show a live status for this application, which usually means the council register holds more recent detail than the copy PlanIndex receives.

The council portal linked on this page carries the authoritative version, including the documents, any consultation deadline and the decision once made. PlanIndex refreshes its copy of the register on a daily cycle.

Prior approval applications arise where permitted development rights already grant the principle of the work, such as larger home extensions, changes of use to housing or agricultural buildings. The council may only consider the specific matters set out in the rules, for example transport, flooding or appearance, and in many classes the work may proceed if the council does not respond within the deadline, commonly 56 days.
