Planning permission completion certificate
Planning permission is the granting of permission to proceed with a proposed development. Responsibility for granting permission generally lies with local planning authorities (usually the planning department of the district or borough council).
See Planning permission for more information.
Unless the permission states otherwise, development should begin within three years of the date permission was granted. If the development has not commenced within three years, the permission will be considered to have expired.
Once the development has commenced, the permission remains in place unless the local authority serve a completion notice. If such a notice is served, the development must then be completed within 12 months. In the absence of such a notice, the permission remains in place.
Applicants are required to inform the local planning authority when the works are complete and in some circumstances the permission may have included conditions that must be satisfied before the development is occupied.
No completion certificate is issued by the planning authority.
