Clean Air Zone - Latest

Clean Air Zones live

Since the first Clean Air Zone was started in London and expanded on 25th October 2021 to include areas inside of the North Circular Road (A406) and South Circular Road (A205), and the PHEV 100% exemption was withdrawn. Other Clean Air Zones (CAZ's) have started to operate.

Outside of London, Bath City centre has imposed a Class C (see below for classification table) Clean Air Zone since 15th March 2021. However, the decision about Bristol's Clean Air Zone which was delayed is now set for 28th November 2022.

And on 29th November 2021 the CAZ in Portsmouth went live, this is a B Clean Air Zone meaning non-compliant HGVs, buses and coaches will be charged, see the below table for details and future clean Air Zones to go live.

If you deliver goods into city centres then Clean Air Zones will need to be factored into either your delivery costs, (Portsmouth CAZ will charge HGV's £50/day while Bath CAZ charges £100/day for an HGV to enter the zone) or into the cost of replacing your fleet with lower emission or emission free vehicles.

It is therefore likely that many companies will operate mixed fleets for quite some time as vehicles are replaced, so choosing the correct vehicle for deliveries into Clean Air Zones will become vitally important to ensure that charges are kept to a minimum. Once the parameters of your vehicles are entered into the Descartes’ routing software it will automatically select the best vehicle from your fleet when scheduling deliveries within clean air zones.
