Do I require Planning Permission ?
 

This part of the Web Site gives general guidance about the kinds of work for which you need to apply for planning permission and those for which you do not.

If you have any queries about a particular proposal, the first thing to do is to contact the Planning Service. Contact details for Divisional Planning Offices can be obtained from the Contact Us page on this Website.

Please Note: It is your responsibility for seeking, or not seeking, planning permission. If required, planning permission should be granted before any work begins.


General Advice         

If you are in any doubt about whether you need to apply for planning permission, you should consult the Planning Service immediately. We will advise you as best we can but, if you want to obtain a formal ruling you (or your adviser) can apply, on payment of a fee, for a certificates of Lawful Use or Development, as to whether a particular proposal constitutes development and if it requires permission. You do this by completing the appropriate form with details of the work you want to carry out and sending it to the Planning Service. Application forms for Certificates of Lawful Use or Development can be downloaded from this Website by clicking here.
 

Please Note: If you build something which needs planning permission without first having obtained permission, you may be forced to put things right later, which could prove troublesome and costly. You might even have to demolish an unauthorised building.
