The Town and Country Planning (General Permitted Development) Order 1995 (as amended) - 'the GPDO' - grants planning permission (known as 'permitted development rights') for certain types of development and changes between use classes.
Exceptionally, permitted development rights may have been withdrawn. In those circumstances, a planning application may be necessary, although no fee will be payable.
