Extending or carrying out work on your homeView the Planning Portal interactive guide to find out whether you require planning permission.
You can also use our set of self assessment forms to assess whether you require planning permission for your proposed development. If you answer 'yes' to any of the questions in the forms, or do not comply with any conditions, then you will need to make a planning application.
You should complete a self assessment form, even if you are just replacing an extension or outbuilding and base your answers on the proposed works taking place.
You are also advised to check whether:
- Permitted development rights have been removed: Download a permitted development rights enquiry form (DOC)
- Your property is in a conservation area or if it is a listed building
If you want written confirmation that planning permission is not required, then you will need to submit a certificate of lawful proposed development.
You may also require building regulations consent for the works you are proposing. Please refer to building regulations for further guidance.
