Check if you need permission

It is important to check if you need planning permission before making changes to your home, business premises or starting a development.

For information on what you need to do and what is permitted at different stages of developments view the Planning Portal’s guidance.

If you complete works without planning permission you may have to remove your alterations and may even be reported for breaching planning control.

Check if you need planning permission on the Planning Portal

Article 4 Directions

Some developments will have Article 4 Directions attached which means that the projects will need planning permission for works that would not normally be needed.
