Manufacturers of abatement equipment need to get their equipment accredited by one of our recognised certification bodies before it can be added to the list of approved devices available to operators. This ensures that approved filters meet minimum technical standards and that vehicles fitting these approved filters meet the Low Emission Zone (LEZ) emissions standards.
It is the responsibility of manufacturers and suppliers to certify their pollution abatement equipment.
Pollution abatement equipment can be added to the Low Emissions Certificate (LEC) Approved Devices List if evidence is provided to one of our recognised certification bodies that it meets reduced emissions requirements.
Certified abatement equipment can also be added to the Reduced Pollution Certificate (RPC) Approved Devices List if evidence is provided to the Vehicle Certification Agency that it meets all scheme requirements.
Vehicles not registered in Great Britain and fitted with abatement equipment may register with us providing evidence that they meet the required emissions standards for particulate matter (PM).
We will require evidence of the equipment fitted to the vehicle, and the resulting emissions levels for PM. This evidence will be:
Manufacturers are advised to contact us if they are uncertain as to whether their device meets LEZ emissions standards.
