The Planning Portal can be used to find out if you need planning permission. You can explore the interactive house and mini guides on the Planning Portal for guidance on many common householder projects in England.
Alternatively there are two ways which you can determine if planning permission is needed, through the council:
You can use the self assessment forms below, which are based on the information you have about the proposal (no fee);
Or
You can submit a certificate of lawfulness (£129 for proposed works / £258 for retrospective) which allows you to be certain that the existing use of a building is lawful for planning purposes or that your proposal does not require planning permission.
