Generally, if it is proposed to change from one use class to another, you will need planning permission. Most external building work associated with a change of use is also likely to require planning permission. There are some exceptions that are covered in more detail below.

If you are proposing to change the use of buildings or land, we would always recommend that you seek advice from the local planning authority to confirm whether planning permission is required or not.

Additionally, before you lease or buy a property for your business, you should check whether you need to obtain planning permission for its intended use, and if so, your chances of getting it.
