Changes to Wood Waste

1st September 2023


Waste Wood Briefing Note


From 1st September 2023 the Environment Agency in the UK has changed the classification of certain types of waste wood: some types of waste wood are now classified as hazardous waste.

From 1st September 2023 waste operators will need to separate the waste wood arising from Demolition jobs into Non-Hazardous and Hazardous types, by using the CIWM ‘Waste Wood Assessment Guidance for the Construction and Demolition Sectors’. As a result, we are asking all customers to declare if their waste wood is hazardous or non-hazardous.

For more information on the changes to the classification of certain types of waste wood, please read the Environment Agency’s RPS 250 and the CIWM C&D Waste Forum Waste Wood Guide.


The main materials of concern are:

  • Fence posts
  • Decking

Buildings built between 1950 to 2007:

  • Barge boards, Soffitts, Fascias
  • External Joinery (wooden windows and conservatories) External doors
  • Roof Timbers
  • Tiling and Cladding Battens
  • Timber Frames / Joists

Items such as railway sleepers, telegraph poles, waste wood from docks, cooling tower timbers, wood block flooring/moulds, wood from boats, carriages, trailer or wood treated with creosote, are also classified as Hazardous Waste.

The above items must be kept separate from other wood and moved as Hazardous Waste.

To determine whether your wood waste is classified as hazardous or non-hazardous, please use the Waste Wood Flow Chart and the WRA’s Visual Guide on Potentially Hazardous Demolition Waste Wood.

Please fill in the Wood Waste Declaration Form to declare whether your waste wood is hazardous or non-hazardous. We MUST have your declaration form completed before your waste can be collected from you or delivered to us.

Please contact the Commercial team on 235300 or email, if you have any questions or require additional guidance.
