   Awaiting decision

   Decision expected by 17 August 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.

A lawful development certificate is a legal determination, not a planning judgement. It asks the council to confirm either that existing use or works are lawful, often through the passage of time, or that a proposal would not need planning permission at all. The applicant must prove the facts; the merits of the scheme are not considered.
