Planning permission, in simple terms, is like asking if you can do a certain piece of building work. It will be granted – sometimes with conditions – or refused.
You can make some types of works to your house without needing planning permission. These are called permitted development rights.
Planning Portal: permission has lots of guidance on planning permission and when you will need it. You can explore the online houses linked below to find out about specific types of work.
