Why planning permission is important
You may need planning permission for different types of developments or projects, for example:
- new building work
- change of use of land or buildings
It is important to find out if you need permission before you make any improvements or changes to your property or land.
If you go ahead without permission, you may have to put things back to how they were.
You will need planning permission for a larger home extension or a project that involves a protected tree.
How to find out if you need planning permission
To find out if you need planning permission you can:
If you need a formal response, you can submit a Proposed Lawful Development Certificate (LDC).
To see if you are likely to get planning permission or to check any validation requirements, you can apply for pre-application advice.
Building regulations
Even if you do not need planning permission, you may still need separate approval under the Building Regulations.
