The Department for Environment, Food and Rural Affairs (DEFRA) has announced the addition of two new Clean Air Zones (CAZ) in Bath and Birmingham.


Bath’s CAZ will come into effect from 15 March 2021, private cars and motorcycles will be exempt, and other vehicles will only be charged if they exceed Bath’s new emission standards.

Bath’s CAZ will follow the guidelines for a Class C Standard. This ensures that bikers with Euro 3 or newer emissions will still be exempt.

More information about the Bath’s CAZ can be viewed here


Birmingham will follow with their own, slightly stricter, Class D CAZ coming into effect from 1 June 2021.
