You probably need planning permission if you want to:
- build something new
- make a major change to your building such as building an extension
- change the use of your building or land
- merge houses or flats in a way which reduces the overall number of homes
Permitted development rights
Planning permission isn't always required for a development if the works can be carried out using permitted development rights. These are set nationally and not by us.
Find out if you can carry out permitted development on the Planning Portal.
Flats don't have any permitted development rights. If you intend to materially alter the external appearance of a building containing flats you will always require planning permission.
This includes installing double glazed windows in place of single glazed windows in a flat, unless the appearance of the new windows would be identical to the existing windows.
Changing the use of buildings
Changing the use of buildings does not always need planning permission.
Find out more on the Planning Portal.
New buildings and external changes
New buildings and many external changes to buildings require planning permission, which you can get by submitting a planning application.
How to submit your application
We recommend submitting applications through the Planning Portal.
What if I don't need permission?
If you would like the Council to confirm that you don't need planning permission, apply for a Certificate of Lawful Proposed Use or Development through the Planning Portal.
When works are not considered to be permitted development, some people sometimes start the work or change the use of a property without the correct planning consents in place. When this happens our Enforcement Team investigates.
