Whether you need planning permission or not will depend on what you want to do. Some minor alterations and extensions, particularly to houses, can often be carried out without planning permission. This is called permitted development.
But, you may need planning permission to change the use of your property, for example a shop to an office or conversion of a house into flats.
If you want a formal decision as to whether planning permission is required for your development, you will need to apply for a Lawful Development Certificate. Full details of which can be found on our apply for planning permission page.
