Class L – Development by an air traffic services licence holder involving moveable structures
Class L permits the temporary use of land by or on behalf of an air traffic services licence holder for providing services or facilities in connection with air traffic services, together with the erection or placing of moveable structures on that land.
The right is expressly temporary and carries a restoration requirement.
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.
What does Class L allow?
The Class can cover temporary moveable structures used to support air traffic services, provided the statutory licence-holder and purpose tests are met.
The use must cease, the structures must be removed and the land must be restored within the six-month period set by the Class, unless another condition has been agreed in writing with the local planning authority.
That six-month condition is a substantive limitation of the permitted development right, not merely good practice.
