Find out if you need planning permission

See planning constraints on your property before you change or build something.

We're having some problems with our planning permission look up at the moment. We're working hard to fix it and are sorry for any inconvenience.

Before you start any building work or make any changes to your property you must check if you need planning permission.

Your project can be affected by two types of constraints. These are:

  • national guidance on what is allowed, known as permitted development rights
  • local constraints, including whether your property is in an area that we have restricted development on

Flats and maisonettes don't have any permitted development rights, so if you plan to change the outside appearance of a flat you'll need planning permission.
