The Bath Clean Air Zone: What you need to know

In 2018, Bath & North East Somerset Council agreed to introduce a Clean Air Zone (CAZ) to improve air quality in Bath.

The decision followed orders from the government to reduce the illegal nitrogen dioxide levels in the city as quickly as possible.

Launched on 15 March 2021, Bath’s CAZ charges high-emission taxis, vans (including pick-ups and some camper vans), light goods vehicles, buses and other large vehicles to travel through the city centre. 

There are four classes of CAZ – A, B, C and D, and they exempt various vehicles, but the emissions standards are in line with the London Ultra Low Emission Zone (ULEZ). 

The specific class into each CAZ falls is determined by the local authority that implements it, but they are regulated by a national Clean Air Zone framework, outlined by the UK government in February 2020. 

Bath’s zone is a class C CAZ, which doesn’t charge private cars and motorbikes. If you drive a zero emissions EV, you will not be charged to enter a CAZ. The petrol or diesel engines on hybrid cars have to meet the relevant criteria, as set out in each individual CAZ.

Information correct as of December 2022

The Bath CAZ covers roads in Bath City Centre, and areas including Kingsmead, Bathwick, Walcot and the Royal Victoria Park. 

Motorists can check if a post code is in the CAZ before travelling.

Costs vary according to vehicle type:

Trucks and lorries£100
Taxis£9
Minibuses£9

Although vehicles that don't meet emissions standards can enter or leave the zone multiple times in one day, their owners have to pay two daily charges if they travel in the zone across two different days, e.g. before midnight and after midnight.

Charges don’t apply if one of the vehicles listed above stays parked in the zone.

If your vehicle is deemed non-compliant, you might qualify for an interest-free grant to help replace it – or pay towards adapting your vehicle to meet emission standards.
