To check if a new van is CAZ compliant, you need to check it against the rules of the specific city’s Clean Air Zone (they’re not identical), then confirm your exact vehicle on the official online checker using its registration (once you have it) or its Euro emissions standard and fuel type (before it’s registered).
1) Know what “compliant” usually means for vans
Most UK CAZ schemes assess vans by Euro standard:
- Diesel vans: typically need to be Euro 6
- Petrol vans: typically need to be Euro 4
Most brand-new diesel vans on sale today are Euro 6, but don’t assume – some specialist conversions or older-stock vehicles can catch people out.
2) Use the official checker (best once the van has a reg)
If you already have the van’s registration number (for example, a demonstrator or a vehicle you’re about to take delivery of), use the relevant authority’s CAZ checker. Many areas also link through the Government’s vehicle checker. You’ll get a clear “pay/no pay” result for that zone.
3) If it’s not registered yet, check the paperwork before ordering
Ask the dealer/leasing company for written confirmation of:
- Euro emissions standard (e.g. “Euro 6e” still counts as Euro 6 for CAZ purposes)
- Fuel type (diesel/petrol/electric)
- Vehicle category and gross vehicle weight (GVW) if you’re close to 3.5 tonnes, as some rules differ for heavier vehicles.
Common follow-ups
Is an electric van CAZ compliant? Yes—battery-electric vans are generally exempt from CAZ charges, but always check the local rules.
Do CAZ rules change? They can. Charges, exemptions and zone boundaries are set locally and can be updated, so check the latest position on the relevant council/CAZ website (and Gov.uk links) before you commit to a new van order.
