   Awaiting decision

   Decision expected by 3 April 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.

This application sits outside the common categories, which can include county matters such as minerals and waste, works by statutory undertakers, demolition notifications and other less frequent procedures. The council record linked below sets out the specific procedure that applies, and the description above is taken directly from the published register.
