You need planning permission for most building work.
You need to apply for planning permission for most building work. New structures will generally need planning permission, but extensions, demolitions, and works to protected trees may also require planning permission.
Complying with building regulations and obtaining planning permission are separate matters, so if you have planning permission, you also need to check whether you need building regulations approval. For more information about the Building Control Regulations, please visit our Building Control pages.
If you have any doubt about what permission you need, please contact us for advice before starting work.
