You can find out if you need planning permission or building regulations on the national Planning Portal website. This features a list of projects, case studies, mini-guides and an interactive house that provides a good overview of what does and does not require planning permission.
Permitted development
Certain forms of development can be carried out without a planning application. This is called ‘permitted development’. However, it is best to check with us first because some of these rights might have been removed or the scope of development restricted, meaning planning permission may be required after all. Either way, you will still need building regulations approval.
Lawful Development Certificate (LDC)
For peace of mind that a proposed use of a building is lawful or that the proposal doesn't require planning permission, you can apply for a Lawful Development Certificate prior to commencing any building works or change of use.
There is a fee for this service. More information is available on the Planning Portal where you can also make an application.
If you’re seeking a formal decision as to whether planning permission will be required for a large rear extension (3 metre to 6 metre rear extension on an attached house, or 4 metre to 8 metre rear extension on a detached house), please download and complete our prior notification form.
If you received prior approval for your development or approval was not required, please tell us when you have completed the work.
Dropped kerb and vehicle access crossover
Putting in a dropped kerb makes it easier and safer to access a property from the road. If you want to install a dropped kerb you must obtain formal written permission first.

Pre-application advice service
We provide a pre-application advice service. This can help you establish whether your development is acceptable in principle before submitting a formal planning application. This way any key planning issues and how to address them can be identified early on and applications can be processed more quickly. A fee is payable for this service.
