   Decision issued: Certificate of Lawfulness - Refused

3. 25 Jul 2026

   Added to PlanIndex

The council refused this application for the reasons set out on the decision notice, which the council portal holds in full. Only the applicant can appeal a refusal; the time limit runs from the decision date and is shorter for householder schemes.

Refusal does not prevent a fresh attempt. Applicants often address the reasons for refusal and resubmit, so a refused scheme is not necessarily the end of proposals for the site.

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.
