More than 9.6 million penalty charge notices have been issued to drivers entering emission zones in Bradford, Portsmouth and London, highlighting the potential cost of getting vehicle compliance wrong.
New figures obtained through a Freedom of Information request show just how many motorists have been caught by Clean Air Zones (CAZs) and Low Emission Zones (LEZs), with more than 300,000 repeat offences also recorded.
For businesses operating cars and vans across different parts of the UK, the figures underline the importance of checking local emission zone requirements before sending drivers into unfamiliar areas.

Millions Of Emission Zone Fines Issued
The research, obtained by MotorEasy through a Freedom of Information request, looked at penalty charge notices issued in three locations:
| Location | Period Covered |
|---|---|
| Bradford | 2022–2026 |
| Portsmouth | 2021–2026 |
| London | 2019–2026 |
Across the three areas, more than 9.6 million penalty charge notices have been issued since enforcement began.
The figures also include more than 300,000 repeat offences, demonstrating that emission zone penalties are not simply affecting motorists who make a one-off mistake.
For businesses, this can be particularly significant. A vehicle travelling into a restricted area for work could potentially incur a charge without the driver realising that the vehicle does not meet the relevant emissions requirements.
Why Are Drivers Being Caught Out?
One of the biggest challenges for motorists is that there is no single set of emission zone rules covering every UK city.
Clean Air Zones have been introduced by individual local authorities, while London operates its own emissions schemes. Scotland also has its own Low Emission Zones.
The requirements can therefore vary depending on where a vehicle is being driven.
A van that is suitable for entering one city without an additional charge may not necessarily meet the requirements somewhere else.
This is particularly important for businesses whose drivers regularly travel between different towns and cities.
A driver may be familiar with the rules in their local area but then travel to another city for a customer visit, delivery or service call without realising that different restrictions apply.

Check Your Vehicle Before You Travel
The simplest way to avoid an unexpected penalty is to check whether the vehicle complies before entering an emission zone.
The Government provides an online vehicle checker that allows motorists to establish whether their vehicle will be affected by Clean Air Zone restrictions.
Check your vehicle against Clean Air Zone requirements
Drivers heading into London should check their vehicle using Transport for London’s own vehicle checker, as London’s emissions schemes operate differently from the CAZ system used elsewhere.

Drivers travelling in Scotland can also check the requirements for Scottish Low Emission Zones through the official vehicle emissions checker.

For fleet operators, it is worth making these checks part of the vehicle and journey planning process rather than relying on individual drivers to identify restrictions at the last minute.

Businesses Need To Consider Emission Zones When Choosing Vehicles
Emission zones are also something businesses should consider when replacing or adding vehicles to their fleets.
A vehicle that has previously been suitable for the company’s regular journeys may not necessarily be the best choice if its operating area changes.
This is particularly relevant for businesses expanding into new regions or taking on contracts that require drivers to visit city centres.
Vehicle replacement decisions should therefore take into account more than just the purchase or leasing cost.
Businesses should also consider:
- Where their vehicles are likely to be driven
- Whether drivers regularly enter major towns and cities
- The emissions standard of each vehicle
- Current Clean Air Zone and Low Emission Zone requirements
- Whether the business expects its operating area to change
- Potential future changes to local emissions policies
For fleets with a mixture of cars and vans, this becomes even more important because different vehicles can have different emissions characteristics and compliance requirements.
Replacing Your Vehicle Does Not Automatically Mean Compliance
Another important consideration is what happens when a business changes its vehicles.
Replacing an older van or car with a newer model will generally improve emissions performance, but businesses should still check the specific vehicle against the requirements of the areas where it will operate.
Simply assuming that a newer vehicle will automatically be exempt from every charge could prove costly.
This is especially relevant when choosing between different engines, fuel types and specifications.
For businesses that operate predominantly in urban areas, an electric vehicle may also provide an alternative route to avoiding certain emissions-based charges, although the individual rules and any other applicable charges should always be checked before travelling.
Emission Zones Are An Important Fleet Consideration
The scale of the latest figures demonstrates why emission zones should not be treated as something that only affects private motorists.
For a business operating several vehicles, repeated penalties can quickly become an unnecessary operating cost.
The issue is also unlikely to disappear as cities continue to look at ways of reducing transport emissions and improving local air quality.
For fleet managers, the most effective approach is to understand where vehicles are being used, check the relevant restrictions and make emission-zone compliance part of the vehicle selection and journey-planning process. Our fleet management solutions can also help businesses take a more joined-up approach to managing their vehicles and wider fleet requirements.
What Should Fleet Operators Do?
Businesses can reduce the risk of unnecessary penalties by taking a few straightforward steps.
Before sending a vehicle into an unfamiliar area:
- Check whether an emission zone operates there.
- Confirm the vehicle meets the relevant emissions requirements.
- Check whether a daily charge applies.
- Make sure drivers understand the areas where restrictions apply.
- Consider emission-zone compliance when replacing vehicles.
- Review the fleet regularly as local rules change.
With more than 9.6 million penalty charge notices issued across just three locations, the potential cost of overlooking these requirements is clear.
For businesses running vehicles across the UK, understanding where emission zones operate and ensuring every vehicle is suitable for the journeys it needs to make can help prevent avoidable fines and keep fleet costs under control.
