Applies to England

Waste exemptions are changing and this will affect anyone who carries out a waste exemption activity. Defra has published its consultation supplementary response document and associated annexes explaining these changes. It sets out which exemptions will be withdrawn or restricted. This is one of the waste exemptions that will be affected. We expect changes to the exemptions will start to roll out during 2024 and continue into 2025 but timescales have not been finalised yet.

Construction means building or engineering work - including including:

  • repairing, altering, maintaining or improving existing work and
  • preparatory or landscaping work.

Types of activity you can carry out

These include:

  • using crushed bricks, concrete, rocks and aggregate to create a noise bund around a new development and then using soil to landscape the area
  • using road planings and rubble to build a track, path or bridleway
  • using woodchip to construct a track, path or bridleway
  • bringing in soil from somewhere else to use in landscaping at housing developmentsdevelopments, or as part of another construction activity

Types of activity you cannot carry out

Using more waste than your exemption allows

You must get an environmental permit if you need to use more waste than you are allowed under this exemption.

Check if you can meet the criteria for the standard rules permit SR2015 no 39: use of waste in a deposit for recovery operations. When you apply you must provide a waste recovery plan.

You can apply for a bespoke permit if you cannot meet the conditions of the standard rules permit. Check the guidance on deposit for recovery operators: environmental permits.
