Waste management facility development

Waste management facility development comes under Part 7 of the Order.

Part 7: Class L permits development carried out on land used for the purposes of a waste management facility including:

  • the extension or alteration of a building
  • the installation of a replacement plant or machinery

Class L: Part 7 introduced a new permitted development right for ‘sui generis’ waste management facilities. Sui generis refers to facilities without a category, or use class, under the Town and Country Planning (Use Classes) Order 1987.

This allows operators to replace any plant or machinery and buildings on land within the curtilage (related surroundings) of a waste management facility, which is ancillary (providing necessary support) to the main waste management operation.

It allows minor works where:

  • equipment is being replaced
  • there is an increase of no more than 15% in the floor space occupied by the plant or machinery being replaced
  • the replacement building, plant or machinery does not exceed the existing facilities currently on site by more than 50% or 100m2 (whichever is smaller)

This does not apply in:

  • National Parks
  • Areas of Outstanding Natural Beauty
  • the Broads
  • an area designated as a conservation area
  • World Heritage Sites
  • land within the curtilage of Listed Buildings and Scheduled Monuments
  • Sites of Special Scientific Interest
