Enforcement: Reporting unauthorised works

The Town and Country Planning Act 1990, Planning (Listed Buildings and Conservation Areas) Act 1990 and the Planning and Compensation Act 1991, affords the Council specific powers of enforcement against breaches of planning control. A breach of planning control can include development being implemented which requires planning permission, change of use of land without permission or not complying with details of a permission that has been granted.

The Projects and Compliance Team are responsible for investigating alleged breaches and taking enforcement action where necessary.  For more information, please view the Enforcement Plan.
