Bath Clean Air Zone: Charges, Exemptions and How to Check Your Car

Bath's Clean Air Zone: the short answer

Private cars and motorbikes are not charged to drive into Bath's Clean Air Zone — full stop, regardless of what your car's exhaust emits. That's because Bath's zone is "Class C," and Class C stops at commercial vehicles: taxis, private hire vehicles, vans, minibuses, buses, coaches and HGVs pay if they don't meet the emissions standard, but ordinary cars and bikes never do.

It still matters if you're buying a used taxi, private hire vehicle, van, minibus, coach or HGV to drive into Bath — a non-compliant one costs money every day you use it there, worth knowing before you agree a price rather than after. This guide is part of our wider guide to MOT, road tax and staying legal.

What is Bath's Clean Air Zone (Class C)?

Why "Class C" means private cars are exempt

Each English Clean Air Zone gets a class that decides who pays. Classes A to C charge only commercial and larger vehicles — taxis, private hire vehicles, buses, coaches and HGVs, with Class B and C adding vans, minibuses and LGVs. Class D is the only class that adds ordinary private cars and motorcycles on top. Bath is Class C, so private cars and motorbikes are never charged there, whatever their emissions standard.

For how Bath's zone compares with the other six English Clean Air Zones, London's ULEZ and Scotland's Low Emission Zones, our wider guide to ULEZ and Clean Air Zones covers all of them side by side.

The zone boundary

Bath's Clean Air Zone covers the city centre, taking in the Kingsmead, Bathwick and Walcot areas and the Royal Victoria Park area. It operates 24 hours a day, every day of the year, so there's no out-of-hours or weekend exemption to rely on. For the precise boundary — which streets are in and which are just outside — check Bath and North East Somerset (B&NES) Council's own zone map rather than relying on a landmark description alone.

Who actually pays — and how much

£9 a day — taxis, private hire vehicles, vans and minibuses

If it doesn't meet the emissions standard, £9 a day is what you'll pay to drive a taxi, private hire vehicle, van, LGV, minibus, pick-up or campervan into Bath's Clean Air Zone.

£100 a day — coaches, buses and HGVs

Larger non-compliant vehicles — coaches, buses and HGVs — pay £100 a day.

How and when to pay

You don't have to pay on the day you travel. You can pay up to 6 days before you plan to drive into the zone, on the day itself, or up to 6 days afterwards. The charge has to be paid within 7 days of travelling (including the day itself), or a penalty is issued — see below.

This charge sits on top of your road tax, not instead of it — see car tax bands explained for what VED itself costs a used-vehicle buyer.

Which vehicles are exempt from Bath's CAZ charge

The compliant-vehicle exemption

Whether a charged vehicle type pays comes down to its actual emissions standard, not its age or badge:

• Diesel: Euro 6 or newer — most diesels registered from around September 2015.
• Petrol: Euro 4 or newer — most petrol vehicles registered from around 2006.
• Electric, hydrogen fuel cell and hybrid vehicles: exempt.
• Vehicles retrofitted with technology accredited under the Clean Vehicle Retrofit Accreditation Scheme (CVRAS): exempt.

Local exemptions and discounts

Local exemptions and discounts are applied for through the MiPermit Portal, generally up to 14 days ahead of travel. We couldn't confirm a full, specific eligibility list for these against a primary source — if you think you might qualify, check your circumstances directly with B&NES Council rather than relying on a general summary.

How to check if a car you're buying will be charged

The mistake buyers make is checking this after they've already agreed to buy, when a seller is waiting on an answer. Check the exact registration before you view the vehicle, not after you've handed over a deposit.

Run the reg through our Bath Clean Air Zone check — it tells you whether that specific vehicle is liable for Bath's charge, alongside the rest of our free vehicle information. If you might also drive it somewhere covered by London's ULEZ or another English Clean Air Zone, run our ULEZ check alongside it for a wider picture.

It's also worth running an MOT check on the same registration — a vehicle that isn't currently taxed or MOT'd is a separate problem from Clean Air Zone compliance, but the two often turn up together on a neglected vehicle.

What happens if you don't pay

Miss the payment window and you'll get a Penalty Charge Notice of £120, reduced to £60 if you pay within 14 days.

If you think the PCN was issued wrongly — the vehicle was exempt, or you did pay but it wasn't recorded — you can make representations to the council within 28 days of the notice, then a further right of appeal to the independent Traffic Penalty Tribunal if that's rejected. This is general guidance, not legal advice for your specific case.
