The council has decided this application; the published outcome sits in the record above and the decision notice on the council portal carries the detail, including any conditions.

If permission was granted, work must normally begin within three years of the decision. If it was refused, the applicant can appeal within the statutory time limit or submit a revised scheme.

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.
