Register a U1 waste exemption听

You must register with the Environment Agency.

There鈥檚 a different registration process for using waste to carry out repairs along a linear network. See the section 鈥榃aste activity along a linear network鈥�.听

Charities register by phone听

Charities and organisations that work only for charitable purposes do not have to pay for waste exemptions. If you鈥檙e a charity, call the Environment Agency to register free of charge.

Registration rules听

You cannot:听

• register more than one U1 at the same site听

• register a U1 if it鈥檚 already been registered at the site by another business听

• renew your registration more than one month before the 3-year registration period ends听

• increase the storage limit by registering a separate storage exemption听听

• store waste that is not included in your exemption听

Once you鈥檝e registered a U1 exemption, the maximum waste limit applies to the site for 3 years.听

Waste activity along a linear network听

Linear networks are long stretches that do not have a defined address or gridpoint. They may run for several miles and have more than one site postcode. They include roads, rivers, canals and railways.听听

You can use a U1 exemption for maintenance or repair work along a linear network, such as filling in potholes along several miles of road.

You鈥檒l need to fill in a linear networks registration form instead of using the online registration service. 听

Maintaining a linear network听听

You can use up to 500 tonnes of these waste types per linear mile, per year, in any combination, for maintenance and repair activity.听
