Check if you need planning permission

New building projects and extensions or alterations to current buildings will often need planning permission. However permitted development rights allow you to make minor changes to your property without needing permission. As it can often be  confusing, we recommend that you follow the advice contained in the Is Planning Permission required guidance sheet before starting any work.

How do I use it?

If you are unsure whether you need planning permission, you can find help and advice on the Planning Portal

If you want to be certain that your proposed works do not require planning permission you can apply for a Lawful Development Certificate (LDC) on the Planning Portal website. This is not compulsory, but you need one to prove that your activities are lawful.

Please also provide us with sufficient information in order that we can reach a decision. If we do not have sufficient information we may refuse your application.
