Clean Air Zones and ULEZ: A Fleet Guide to the UK's Emissions Charges

Emissions-based charging has spread well beyond London, and for a fleet that means a patchwork of zones, standards, and daily charges that change from city to city. Miss one and the charge quietly becomes a penalty. Here's how the main schemes work and what fleets need to track.

London's ULEZ

The Ultra Low Emission Zone (ULEZ) covers every London borough and operates 24 hours a day, every day except Christmas Day. Cars, vans, and minibuses that don't meet the standard, broadly Euro 6 for diesel and Euro 4 for petrol, pay £12.50 a day. Heavier vehicles are handled separately by London's Low Emission Zone (LEZ): lorries over 3.5 tonnes and buses and coaches over 5 tonnes that don't meet the standard face daily charges of £100 or £300. A compliant vehicle pays nothing, which is why knowing each vehicle's emissions standard matters.

Clean Air Zones Outside London

Several English cities run Clean Air Zones (CAZ), graded by class:

• Class A: buses, coaches, taxis, and private-hire vehicles.
• Class B: adds heavy goods vehicles.
• Class C: adds vans and minibuses.
• Class D: adds cars.

Cities including Bath, Birmingham, Bristol, Sheffield, Bradford, Portsmouth, and Tyneside operate zones at different classes, so whether your vehicle is charged depends on the city and the vehicle type. Charges vary by zone, typically from around £8 for a non-compliant car up to £100 for an HGV. Always check the specific zone before travelling.

Scotland Works Differently

Scotland's Low Emission Zones, in Glasgow, Edinburgh, Dundee, and Aberdeen, don't charge a daily fee. Instead, non-compliant vehicles are banned outright, and driving in breach incurs a penalty that escalates with repeat offences. For fleets, that makes vehicle compliance, not payment, the only option.

Why It's Hard for Fleets

The difficulty isn't any single zone, it's tracking which of your vehicles is compliant where, and making sure charges are paid on time in the zones that charge. A non-compliant vehicle sent into the wrong city, or a charge left unpaid, turns into a Penalty Charge Notice, the same avoidable escalation covered in our guide to challenging a fleet PCN.

How Fleevo Helps

Fleevo holds each vehicle's emissions standard alongside its journeys, so you can see which vehicles are compliant in which zones and make sure charges are paid before they become penalties. Zone charges sit alongside your tolls, fuel, and fines in one place. Explore PCNs & Fines Management, or read our guide to the London Congestion Charge.

Clean Air Zone FAQs

How much is the ULEZ charge?

£12.50 a day for non-compliant cars, vans, and minibuses. Heavier vehicles fall under London's separate Low Emission Zone, with daily charges of £100 or £300 for non-compliant lorries, buses, and coaches.

What are the Clean Air Zone classes?

Class A covers buses, coaches, taxis, and private-hire vehicles; B adds HGVs; C adds vans and minibuses; D adds cars. Which vehicles are charged depends on the city's chosen class.

Do Scottish Low Emission Zones charge a daily fee?

No. Glasgow, Edinburgh, Dundee, and Aberdeen ban non-compliant vehicles outright and issue escalating penalties for breaches, rather than charging a daily fee.

What happens if a zone charge isn't paid?

It becomes a Penalty Charge Notice, a fine far larger than the daily charge, so tracking and timely payment matter across a fleet.
