   Added to PlanIndex

Permission has been granted, usually subject to conditions listed on the decision notice, some of which must be discharged before work starts. The decision notice on the council portal sets out exactly what was approved.

Work must normally begin within three years of the decision or the permission lapses. Neighbours cannot appeal a grant; challenging one means judicial review of how the decision was made, within tight time limits.

This type of application deals with conditions attached to an existing permission, either by supplying the details a condition requires, called discharging it, or by asking to vary or remove one. It does not reopen the principle of the permission itself. Building often cannot lawfully start, or continue past a set stage, until the named conditions are discharged.
