★ Key takeaway
Bath operates a Class C CAZ — taxis, vans, LGVs, buses, coaches and HGVs are charged but private cars and motorbikes are not. £9/day for non-Euro-6 LGVs and taxis; £100/day for non-Euro-VI HGVs, buses and coaches. The zone covers central Bath including Roman Baths and Bath Spa station. Operated by Bath & North East Somerset (BANES) Council. |
Bath operates a Class C Clean Air Zone (CAZ) covering central Bath, charging non-compliant taxis, light goods vehicles (LGVs), heavy goods vehicles (HGVs), buses and coaches. Private cars and motorbikes are not charged in Bath CAZ, distinguishing it from Class D zones in Birmingham and Bristol where private vehicles also face daily charges. Compliant vehicles (Euro 6 diesel, Euro 4 petrol, electric, hybrid) enter free of charge. Non-compliant LGVs and taxis pay £9/day; non-compliant HGVs, buses and coaches pay £100/day. The zone covers central Bath including the Roman Baths, Bath Abbey, Bath Spa railway station, and the main shopping districts. Bath & North East Somerset (BANES) Council administers the zone. This guide covers the zone map, vehicle classes, exemptions, the resident business grant scheme, and how to check whether a vehicle will be charged before entering.

Why Bath chose a Class C CAZ
Bath's Class C designation reflects a calculated political and practical choice: target commercial vehicles whose emissions are highest, while avoiding the political backlash of charging private car owners. Bath was the first English city outside London to launch a CAZ, going live in March 2021. The Class C model has produced measurable air quality improvements while maintaining political acceptability, with NOx levels at the worst-affected monitoring stations declining steadily through 2022-2025.
The Class C choice means Bath residents driving private cars enjoy unconstrained access to the city centre, unlike Birmingham or Bristol residents who face Class D charges. Visiting tourists similarly drive private cars in without charge. The cost burden falls on freight, taxi, and bus operators, who have largely transitioned to Euro 6/VI fleets in response.
The zone boundary
The Bath CAZ covers central Bath including the Roman Baths, Bath Abbey, Pulteney Bridge, the Royal Crescent, the Circus, Bath Spa railway station, the main retail areas (Milsom Street, SouthGate, Stall Street), and the major hotels and venues. The zone boundary follows the river Avon to the south and east and extends north and west to encompass the historic Georgian core. The official zone map is at bathnes.gov.uk/clean-air-zone and on the gov.uk vehicle compliance checker.
The boundary is enforced by ANPR (Automatic Number Plate Recognition) cameras at zone entry points. There is no "drive-through-only" tolerance: a non-compliant commercial vehicle entering the zone for any duration triggers a daily charge. Day-only operations (a delivery van entering once at 09:00 and leaving at 11:00) pay the full £9 daily rate.
Resident and business support schemes
BANES Council operates resident and business support schemes to help non-compliant vehicle owners upgrade. The Hardship Discount provides 100% discount on daily charges for low-income owners of non-compliant vehicles, with eligibility criteria available on the council website. The Local Business Grant supported small businesses with retrofit and replacement during the early CAZ rollout, partially funded by central government. Most current applicants find the scheme has now closed to new applicants given the council's transition to a fully compliant business fleet across the central area.
Taxi and PHV operators have specific support routes through licensed-trade vehicle support, including incentives for upgrading to electric or hybrid taxis. Bath's licensed taxi fleet has substantially shifted to Euro 6 diesel, hybrid and EV vehicles since the CAZ launch.
Exemptions and discounts
Standard CAZ exemptions apply: vehicles in DVLA Historic Vehicle tax class are exempt; vehicles in Disabled tax class are exempt; emergency service vehicles are exempt; military vehicles are exempt. Specialist agricultural and showman's vehicles benefit from specific exemption categories. Vehicles compliant with the relevant Euro standard (Euro 6 diesel, Euro 4 petrol, fully electric, hybrid) pay nothing regardless of vehicle class.
No exemption applies for residence in the zone alone — Bath residents owning non-compliant LGVs or taxis pay the same daily charges as visiting trades. The Hardship Discount provides relief on income-based grounds for individual owners but is not a residence-based exemption.
How to check and pay
Drivers and operators check vehicle compliance at gov.uk/clean-air-zones using the registration number, which returns the daily charge for Bath and other UK CAZs. Payment is made via the central gov.uk CAZ account (used by Bath, Bradford, Birmingham, Bristol, Portsmouth, Sheffield and Tyneside), either before the trip or up to 6 days after. Auto-pay options debit a linked card automatically once the vehicle is logged.
For occasional visitors, paying after entering is the simplest route: the gov.uk system records the entry via ANPR and prompts payment within the 6-day window. Missing the payment window triggers PCN issuance, which then requires payment of £120 (£60 within 14 days). Setting up auto-pay is recommended for any operator making more than 5 trips per year into Bath CAZ.
Air quality results since launch
BANES Council reports that NOx levels at the most polluted monitoring stations in central Bath have declined approximately 25% since CAZ launch in March 2021. Particulate matter (PM2.5) has declined more modestly, reflecting the broader sources of particulates beyond vehicle exhaust. The Bath CAZ is widely regarded as a successful policy template for medium-sized historic cities, balancing air quality with economic and tourism considerations.
Defra national air quality data corroborates BANES Council figures, showing Bath central monitoring locations now closer to compliance with annual NO2 limits than at any time in the past decade. The compliance trend in Bath has been used by other councils (Newcastle, Sheffield, Bradford) to justify their own CAZ launches between 2022 and 2024.
Tourism and visitor impact
Bath's tourism economy receives over 5 million visitors annually, many arriving by coach. The £100/day coach charge for non-compliant vehicles influences tour operator vehicle choice, with the dominant tour coach operators serving Bath now running fully Euro VI fleets. Day-trip coaches from London, Cardiff, Bristol and the Cotswolds have largely transitioned by 2024, and the city centre experience for visitors arriving by coach has improved as a result.
Tourists driving private cars are unaffected by Bath CAZ charges and can use the central Bath car parks without any zone-related cost. Park-and-ride services at Lansdown, Newbridge and Odd Down provide an alternative for those preferring to leave their car at the periphery. Several Bath hotels offer EV charging at premium parking rates, supporting EV-based tourism.
Comparison with other Class C zones
Other UK Class C CAZs (Sheffield, Bradford, Tyneside) charge similarly for LGVs and HGVs but with regional variations. Sheffield charges £10/day for non-compliant LGVs (compared to Bath's £9), while Bradford matches Bath at £9. The £100/day HGV rate in Bath is at the high end among Class C zones, reflecting the city's particularly sensitive heritage environment and narrow streets. Bath's UNESCO World Heritage status places additional pressure on local authorities to manage commercial vehicle pollution, contributing to the relatively high HGV charge calibration compared to other Class C cities of comparable size. The heritage protection angle also influenced the precise zone boundary, which was drawn to capture all UNESCO-recognised streetscapes while excluding outer commercial districts.
| Vehicle type | Compliant standard | Daily charge if non-compliant |
|---|---|---|
| Private car | N/A (not charged) | £0 |
| Motorbike | N/A (not charged) | £0 |
| Taxi / PHV | Euro 6 diesel / Euro 4 petrol / EV | £9 |
| LGV / van | Euro 6 diesel / Euro 4 petrol / EV | £9 |
| HGV | Euro VI diesel | £100 |
| Bus / coach | Euro VI diesel | £100 |
| Historic Vehicle (40+ years) | Auto-exempt by tax class | £0 |
| Disabled tax class | Auto-exempt by tax class | £0 |
| ★ EDITOR'S VERDICT Bath's Class C CAZ provides a politically calibrated framework: substantial reductions in commercial-vehicle pollution in central Bath without charging private car drivers. For taxi, LGV, HGV and coach operators serving central Bath, fleet upgrade to Euro 6/VI is now the norm rather than the exception. Visitors driving private cars enjoy unrestricted access. The £9/day rate for taxis and LGVs is set deliberately at a level that nudges fleet upgrade rather than imposing punitive cost. The £100/day for HGVs and coaches is sufficient to drive operator behaviour change. Bath's CAZ is a model that other historic medium-sized cities (York, Cambridge, Oxford) may follow. |

What's the daily charge for a non-compliant van?
£9/day for non-Euro-6 diesel LGVs (and non-Euro-4 petrol). The same rate applies to taxis and PHVs. Compliant vans (Euro 6, EV) pay nothing.
What's the daily charge for HGVs and coaches?
£100/day for non-Euro-VI HGVs, buses and coaches. The high rate reflects the higher emissions impact of larger commercial vehicles.
What area does the zone cover?
Central Bath including the Roman Baths, Bath Abbey, Bath Spa station, Royal Crescent, the Circus, and the main retail and tourism districts. The boundary is enforced by ANPR cameras at zone entry points.
Are residents exempt?
No general residence-based exemption. Bath residents pay the same daily charges as visiting trades for non-compliant vehicles. Hardship Discount provides relief on income-based grounds for some individual owners.
How do I pay the charge?
Via the central gov.uk CAZ account, used by all English CAZs except London. Payment can be made before the trip or up to 6 days after. Auto-pay debits a linked card automatically when the vehicle is logged.
What if I don't pay?
A £120 PCN is issued, reducing to £60 if paid within 14 days. Unpaid PCNs escalate through County Court enforcement. The PCN is sent to the registered keeper of the vehicle.
