Enforcement Planning Enforcement Complaint Form - Introduction This form allows you to report suspected breaches of the Planning regulations online. This form will be sent to our Planning Enforcement Team who will investigate the complaint, and take action where appropriate. After completing the form, you will be allocated a unique reference number - please quote this in any future enquiries. A planning enforcement complaint will be acknowledged once it has been received. After this, the first action will be to assess whether there is a breach of planning control. At this stage, a complainant will only be contacted if further information is required.
