ULEZ & CAZ Guide for Fleet Vans (UK)

This guide explains how Ultra Low Emission Zones (ULEZ) and Clean Air Zones (CAZ) affect vans up to 3.5t and larger trucks, what emission standards mean, charges and exemptions, and key decision points for fleet buyers and operators. Our clear, fleet-focused ULEZ & CAZ Guide for Vans in the UK, especially useful if you’re managing a commercial fleet and want to understand how emission zones will impact operating costs, compliance, and vehicle specification choices.

What Are ULEZ & CAZ?

ULEZ - Ultra Low Emission Zone (London)

Operates 24/7, every day except 25 Dec across all London boroughs.
A pollution-based surcharge applies to vehicles that don’t meet specified emission standards.
Applicable primarily to cars, vans (≤ 3.5 t), motorcycles and specialist vehicles.

CAZ - Clean Air Zone (Other UK Cities)

A similar concept outside London in cities such as Birmingham, Bristol, Bath, Bradford, Portsmouth, Sheffield, and Tyneside.
Defined by classes (A–D) that determine which vehicle types and emission standards are charged.
Fleet vans are typically subject to CAZ Class C or D requirements.

Emission Standards Explained (Euro)

Understanding the “Euro” emission standards is key:

Vehicle Fuel	Standard Requirement for Compliance
Diesel vans	Euro 6 (NOx & PM limits) required to avoid ULEZ/CAZ daily charges.
Petrol vans	Euro 4 (NOx limit) is the baseline to avoid charges.
Electric/hydrogen vans	Zero emissions → automatically exempt from most charges.

Note: Euro 6 diesel typically applies to vehicles registered from around September 2015 onwards; petrol Euro 4 generally aligns with vehicles registered from January 2006.

Daily Charges & Penalties

ULEZ (London)

Daily charge: £12.50 for non-compliant cars, vans, motorcycles and specialist vehicles (≤ 3.5 t).
Penalty for non-payment: Typically a fine (e.g., £160, reduced to £80 if paid promptly).
Vans > 3.5 t are handled under the Low Emission Zone (LEZ) rules - often with higher charges and stricter standards.

CAZ (Other Cities)

Charges vary by city and class - but vans in Class C or D zones commonly pay a daily fee (e.g., £8–£12.50).
Penalties for non-payment differ by authority - always check local signage and online info.

How This Affects Your Fleet

1. Compliance Requirements

For most urban zones (ULEZ & CAZ), ensure your diesel vans meet Euro 6 and petrol vans meet Euro 4 before entering.
Electric vans are typically compliant by default.

Newer Mercedes-Benz vans - especially recent diesel models - are usually Euro 6 compliant out of the factory, making them eligible to enter ULEZ without daily charges.

2. Operations in London

If your fleet regularly enters Greater London, ULEZ is a major cost factor - non-compliant vans can incur a charge of £12.50 per vehicle per day (or more if LEZ also applies).
For vans > 3.5 t, the LEZ standard is Euro VI, and charging/penalty scales differ.

3. CAZ - Other UK Cities

CAZ schemes outside London also charge if your vans are non-compliant - and rules vary by locality (always check the current local CAZ standard).
Some CAZ boundaries or class schedules are stricter (e.g., Class D applies to cars, vans, HGVs, buses).

Checklist for Fleet Buyers & Operators

Before purchasing or deploying vans:

Emissions & Specs

> Confirm Euro emission standard via the DVLA or official checker.

> Prefer Euro 6 diesel or electric vans for urban fleets - this avoids most daily charges.

> Document each van’s compliance status for operational planning.

Route & Zone Planning

> Map routes with likely entry into ULEZ or CAZ zones (especially London or the city where you operate).

> Budget for daily charges if older, non-compliant vehicles can’t be replaced.

Exemptions & Support

> London has limited exemptions for certain vehicle types (e.g., certain non-profits or specialist vehicles with applications).

> For CAZ schemes, check local authority guidance - some offer transitional arrangements or grants for cleaner vans.

Final Summary

Zone	Affects	Standard to Avoid Charge	Typical Daily Cost
ULEZ (London)	Vans ≤ 3.5 t	Euro 6 diesel / Euro 4 petrol or EV	£12.50+ per day
LEZ (London, larger vehicles)	Vans > 3.5 t	Euro VI	Varies higher
CAZ (Other UK cities)	Vans depending on class	Often Euro 6 / Euro 4	£8–£12.50*

Always use the official vehicle compliance checkers (TfL for ULEZ and your local council/CAZ checker) before planning routes or buying vehicles.

Clean Air Zones in Yorkshire: The Latest Data Every Fleet Operator Should Know

Clean Air Zones (CAZ) are now a permanent part of the operating landscape for fleets across Yorkshire. With Bradford and Sheffield both running Class C CAZ schemes - and other northern cities monitoring compliance closely - the financial impact on commercial vehicles is becoming clearer with each new data release.

For fleet operators running vans, HGVs, or mixed commercial vehicles across the region, understanding the real‑world costs is essential. Below is the latest verified data from Bradford and Sheffield, along with insights into what it means for businesses across Yorkshire and Northern Lincolnshire.

Bradford CAZ: The Hard Numbers

Bradford remains one of the UK’s busiest Class C Clean Air Zones, and the data shows just how significant the impact has been on commercial fleets.

Penalty Charge Notices (PCNs) Issued

- 128,963 PCNs issued in the first 11 months (Sept 2022 – Aug 2023)

- Updated FOI data shows 315,900 PCNs issued between Sept 2022 and Feb 2025

This makes Bradford one of the highest‑issuing CAZ authorities in the country.

Revenue Generated

- £8.79 million collected in the first 11 months

- By Feb 2025, total revenue exceeded £20 million, including:

- £7.97 million from CAZ charges

- £13.41 million from PCNs

Charges and Fines

- PCN: £120, reduced to £60 if paid within 14 days

- Daily CAZ charge: £7, £9, or £50, depending on vehicle type

Vehicles Affected

As a Class C zone, Bradford charges:

- Vans & LGVs

- HGVs

- Buses & coaches

- Taxis & private hire

- Minibuses

Private cars remain exempt, but commercial vehicles make up a large share of the penalties.

Health Impact

Bradford Council reports measurable improvements since launch:

- 598 fewer respiratory GP visits per month

- 134 fewer cardiovascular visits per month

- Estimated NHS saving: £30,700 per month

Sheffield CAZ: What Operators Need to Know

Sheffield’s Class C CAZ covers the city centre and inner ring road, affecting many fleets travelling between South Yorkshire, West Yorkshire, and the M1 corridor.

Daily Charges

- £50/day for HGVs, buses, and coaches

- £10/day for vans, LGVs, and taxis

Who Is Charged

Non‑compliant:

- Vans & LGVs

- HGVs

- Buses & coaches

- Taxis & private hire

- Some SUVs/4x4s used commercially

While Sheffield has not published PCN totals as extensively as Bradford, the charging structure and compliance rules are well established.

What This Means for Yorkshire Fleets

For operators running routes through Bradford, Sheffield, Leeds, Hull, Doncaster, or the wider M1/M62 corridor, the message is clear:

CAZ charges are no longer occasional - they are becoming a predictable operational cost.

Common impacts we see across Yorkshire fleets include:

- Unexpected monthly CAZ bills

- Older diesel vans becoming financially unviable

- Route planning needing complete revision

- Increased admin time managing compliance and penalties

- Pressure from customers to demonstrate environmental responsibility

With hundreds of thousands of CAZ penalties issued in Bradford alone, the risk of being caught out is significant.

Northside Truck & Van Limited is an Appointed Representative of Automotive Compliance Ltd who is authorised and regulated by the Financial Conduct Authority (FCA No. 497010). Automotive Compliance Ltd’s permissions as a Principal Firm allow Northside Truck & Van Limited to act as a credit broker, not a lender, for the introduction to a limited number of lenders.

We are a credit broker and not a lender. We can introduce you to a lender on our panel, which includes Mercedes-Benz Financial Services UK Ltd, the lender of our vehicle manufacturer. We have commercial arrangements with lenders and credit brokers which are likely to influence who we introduce you to. We are not an independent financial adviser and don’t give you any advice or recommendations. It is your choice whether you enter into any finance agreement.

Our approach is to introduce you first to the manufacturer’s lender, Mercedes-Benz Financial Services UK Ltd, linked to the franchise offering you the vehicle. They will usually offer the best available package for you, taking into account both interest rates and other contributions (but we do not guarantee they do). If they are unable to offer finance, we then seek to introduce you to someone else on our panel. We will usually receive a commission for your introduction. This will be either a fixed fee, or a fixed percentage of the amount that you borrow. This may be linked to the vehicle model you choose.

Mercedes-Benz Financial Services UK Ltd may also provide preferential rates to us for the funding of our vehicle stock and also provide financial support for our training and marketing. But any such amounts they and other lenders pay us will not affect the amounts you pay under your finance agreement. Before we propose you to a potential lender, we will tell you of the likely amount of commission we will receive and seek your consent to receiving this commission. The exact amount of commission will be confirmed before you sign your finance agreement.

All finance applications are subject to status, terms and conditions apply, UK residents only, 18s or over. Guarantees may be required.
