U12: using mulch
Types of waste and maximum amounts you can use for spreading as mulch to benefit land around trees, bushes or plants, under U12 waste exemption.
Applies to England
There’s a charge for most waste exemptions
This exemption is in band 3. Read waste exemption charges to find out what the charges are and how much you’ll pay.
The U12 exemption allows landscapers, farmers and growers to spread mulch using wood chips and plant matter made from waste.
Conditions
You must comply with the exemption conditions.
The waste you use must:
- match the waste codes
- be suitable for mulching
- be stored in a secure location before it is used
You cannot:
- use more waste than is needed to protect and benefit the soil - using more is classed as disposal
- store and use more than the maximum amount allowed
- use waste wood that has been chemically treated
Chemically treated waste wood means it has been preserved, varnished, coated, painted or exposed to chemicals.
Types and amounts of waste you can use
Your waste must fit within the waste code and description.
| Waste codes | Type of waste |
|---|---|
| 02 01 03 19 12 07 20 02 01 |
Untreated wood and plant matter |
You can store or use up to 100 tonnes of mulch in total in any month.
Check if you need other permits
You must comply with other rules that apply to your activity. You’ll need an environmental permit or a different exemption if you want to use:
- waste that is not listed in this exemption
- more waste than is allowed
Waste activity along a linear network
Linear networks are long stretches that do not have a defined address or gridpoint. They include roads, rivers, canals and railways.
You can register a U12 exemption if the mulch is produced and used on the same linear network. You cannot import waste mulch from other sites.
You can use up to 10 tonnes of mulch per linear mile per month.
Register a U12 waste exemption
You must register with the Environment Agency.
Charities register by phone
Charities do not have to pay for waste exemptions. If you’re a charity or organisation that works only for charitable purposes, call the Environment Agency to register free of charge.
Linear networks and multiple site registrations
You’ll need to complete this registration form instead of using the online service.

- have more than one U12 at a site at the same time
- register a U12 if it’s already been registered at the site by another business

- increase the storage limit by registering a separate storage exemption
- store waste that’s not included in the exemption
- deregister an exemption then register it again within 3 years of the start of the earlier registration
