How do I find out if I need planning permission?
Planning permission is required for all new business and commercial premises and most alterations and/or extensions to existing premises.
Further guidance on the need for planning permission and other consents can be found on the Planning Portal website
The Town and Country Planning (Use Classes) Order 1987 (as amended) puts uses of land and buildings into various categories. In many cases involving similar types of use, a change of use will not require planning permission. You can find further information on the Planning Portal - Use Classes and permitted changes webpage
For a simple visual guide explore the interactive terrace on the Planning Portal for guidance relating to flats, shops and basements.
If you are still not sure whether you need planning permission you can submit an application for a certificate of lawfulness for a proposed use or development. You will receive a formal decision as to whether your proposal is permitted development or an application for planning permission is required.
Applications can be made online via the planning portal or paper copies obtained from the planning website or planning reception points.
