Part 8: Transport related development
Part 8 of Schedule 2 to the GPDO contains a group of specialist permitted development rights for transport undertakings and aviation operators in England. It covers railways, ports and waterways, shipping, airports, air traffic services and certain Civil Aviation Authority activities.
These rights work differently from the familiar householder or change-of-use Classes. In many cases the first question is not simply what development is proposed?, but who is carrying it out, on what land and for what statutory or operational purpose?
Part 8 is therefore mainly relevant to statutory undertakers, airport operators and air traffic services licence holders. It should not be assumed that land beside a railway, canal, harbour or airport benefits from these rights merely because of its location.
Need help with permitted development?
Permitted development can avoid a full planning application, but only if the right applies and every relevant limit and condition is met. Planning Geek can check the planning history, Article 4 directions and other restrictions, and help with a lawful development certificate or prior approval where needed.
How Part 8 works
Each Class has its own gateway. Some depend on operational land, some on a particular statutory undertaking or licensed operator, and some impose specific limits on the type or scale of development. The definitions in Paragraph O are important throughout the aviation Classes.
There is no single Part 8 prior approval procedure. Instead, the conditions must be checked Class by Class. In particular, Class B and Class F contain consultation requirements with the local planning authority, together with limited exceptions for urgent small-scale operational works.
The 2021 change to Class B
The most significant modern amendment to Part 8 was made in 2021. Class B was widened so that port and water-transport undertakers could use the right for development connected with services and facilities, expressly including the erection or alteration of an operational building. It was also extended to lessees and agents and made subject to a local planning authority consultation condition.
The same 2021 legislative programme also clarified that the definition of operational building in Paragraph O is for the purposes of Class F.
Other permissions may still be needed
Part 8 grants planning permission where its terms are satisfied. It does not disapply separate controls that may apply to transport, marine, environmental, safety, listed building or other statutory matters. For specialist infrastructure, those parallel regimes can be just as important as the GPDO itself.
