Bath Clean Air Zone (CAZ) – the 2024 guide

    The Clean Air Zone in Bath was implemented in March 2021. Following several years of studying high air pollution levels in the West Country city, the local authority decided to start charging highly-polluting taxis, vans, and large vehicles to enter the city centre.

    Bath has one of many CAZ being rolled out across the UK, including the neighbouring city of Bristol, where private passenger cars are charged if not compliant with emissions standards. 

    For more information about Bath’s CAZ, read on.

    Does Bath have a Clean Air Zone?

    Yes, Bath operates a Class C CAZ. This means that taxis, vans, Light Goods Vehicles (LGVs), Heavy Goods Vehicles (HGVs), buses, and coaches are all charged to enter the zone on a daily basis if they do not comply with the required emissions standards.

    What is a Clean Air Zone (CAZ)?

    In the UK, air pollution has been a big topic, with local research undertaken and targets set, since 2015. Clean Air Zones were found to be an effective way of improving air quality in urban areas with heavy traffic. There were already some LEZ in existence, e.g. in London, which have typically been bespoke in design, depending on the needs and infrastructure of the area. 

    Clean Air Zones, however, all follow a scheme. They are graded in ‘classes’ from A to D, based on what vehicles will be charged to enter the zone if they don’t comply with emissions standards:

    ClassVehicle type
    ABuses, coaches, taxis, private hire vehicles
    BBuses, coaches, taxis, private hire vehicles, heavy goods vehicles (HGVs)
    CBuses, coaches, taxis, private hire vehicles, HGVs, light goods vehicles (LGVs), vans, minibuses
    EBuses, coaches, taxis, private hire vehicles, HGVs, LGVs, vans, minibuses, cars, the local authority has the option to include motorcycles
    UK CAZ classifications and the vehicles they apply to.

    Any town or city running a CAZ has the same compliance standards in place:

    Vehicle typeCAZ minimum standard
    MotorcyclesEuro 3
    Vans, minibuses, taxis, private hire vehicles, carsEuro 4 (petrol engine) and Euro 6 (diesel engine)
    Buses, coaches, heavy goods vehiclesEuro V1
    Battery Electric Vehicles (BEVs)Automatically compliant
    CAZ compliance minimum standards by vehicle type

    The main aspects of CAZ schemes are decided by the UK government, but the fee and penalty costs for non-compliant vehicles, and implementation details including exemptions, are handled by the local council.

    Where is the Bath CAZ?

    Bath’s Clean Air Zone covers The High Common and Royal Victoria Park to the northwest, then extends east to the Bathwick area and King Edward’s School campus. It covers the A36 road and some of its turnoffs, at the southern border, and also covers parts of Wells Road and Oldfield Road.

    When did the Bath CAZ start?

    Bath implemented its Clean Air Zone back in March 2021. Since it’s a Class C CAZ, not charging private passenger vehicles, it’s made less news than neighbouring Bristol, where drivers of polluting cars are charged by the day to enter the regulated zone. The nearby Oxford Zero Emission Zone also charges all drivers – so it’s worth doing some local research if you frequently drive around urban areas in the West.

    In Bath, like in all other Clean Air Zones and Low Emission Zones, charging is based on a daily entrance into the regulated zone.

    What does it cost to drive in Bath?

    The daily rate for entering the Bath CAZ in a non-compliant vehicle varies depending on what you’re driving:

    Vehicle typeCAZ daily charge
    Light Goods Vehicle (LGV)£9
    Heavy Goods Vehicle (HGV)£100 or £9 for private horse transporters and motorhomes, when registered with the council.
    Bus or coach£100
    Daily charge to drive a non-compliant vehicle in Bath CAZ

    If your car is liable for the daily charge, you can pay it online from six days before travel, and up to six days after the day of travel. Failure to do so will result in a Penalty Charge Notice (PCN). This costs £120. If you pay your PCN within fourteen days, the cost will be reduced to £60. If you plan to challenge your PCN, you should do so within the first fourteen days, so that if your challenge is unsuccessful, you still get the discount. 

    Local payments, exemptions, and challenges are all handled through MiPermit.

    Are there grants for getting a compliant vehicle for the Bath CAZ?

    After two years of Bath’s CAZ being implemented, at least 1,000 non-compliant vehicle drivers have been financially supported to upgrade their vehicles. Funding to support individuals and businesses affected by Bath’s CAZ has now closed. 

    what does it cost to drive in Bath
    The Bath CAZ charge can be paid up top six days before and after driving within the zone.

    Does the Bath CAZ have exemptions or exceptions?

    Yes, like all CAZ in the UK, the Bath Clean Air Zone has some exceptions to the daily charge. There are some exempt vehicle categories that are fixed by the government as part of any CAZ in the UK:

    Nationally-exempt vehicles
    Disabled tax class or disabled passenger tax class
    Some agricultural vehicles
    Registered historic vehicles
    Military vehicles
    Ultra-low emission vehicles
    Vehicles retrofitted under the Clean Vehicle Retrofit Accreditation Scheme (CVRAS)
    Vehicles that are exempt nationally from CAZ charges. Information from

    How to check if your vehicle is compliant with Bath CAZ

    To check that your petrol van or minivan is compliant with Euro 4 emissions standards, or that your diesel van or minivan is compliant with Euro 6, simply enter your reg in our ULEZ checker.

    London’s ULEZ is different from Bath’s, in that it charges private passenger cars. However, vans and minivans across both cities have the same compliance criteria, so you can use our ULEZ Checker to make sure you can drive your van in Bath without being subject to penalties.
