Control of development

Pursuant to section 57 of the Town and Country Planning Act 1990 (TCPA 1990), planning permission is required for ‘the carrying out of any development of land’.

‘Development’ is defined in TCPA 1990, s 55(1) as:

  1. the carrying out of building, engineering, mining or other operations in, on, over or under land, or

  2. the making of any material change in the use of any buildings or other land

TCPA 1990 therefore controls two distinct types of development: operational development and material changes of use. This Practice Note deals with operational development. For information on material changes of use, see Practice Note: Planning—material change of use.

It is worth noting at the outset that TCPA 1990, s 55 expressly provides that certain specified operations are not to be taken to involve development, see Works which are not taken to involve operational development below. Further, certain defined operations or changes of use are excepted from the meaning of development pursuant to the Town and Country Planning (Use Classes) Order 1987, SI 1987/764 (the UCO), see Practice Notes: Operation of the Use Classes Order in England and Operation of the Use Classes Order in Wales. Also, the Town and Country Planning (General Permitted Development) Order 2015 (in England) and the Town and Country Planning (General Permitted Development) Order 1995 (in Wales) (the GPDOs) permit specified types of development
