How to Check Your Car's Emissions Class in the UK

Summary

• Check for free online: Use the DVLA vehicle check or our car history check tool.
• Your emissions class affects clean air zone charges: Older, more polluting cars face daily fees in many UK cities.
• Know before you buy: Checking the emissions class helps you avoid buying a car that will cost extra in clean air zones. See our clean air zones guide.

With clean air zones expanding across the UK, knowing your car's emissions class is more important than ever. Here is how to check it.

Method 1: DVLA Online Vehicle Check

Method 2: Check Your V5C Logbook

Your V5C (logbook) may list the emissions class under the vehicle details section. Look for "Euro standard" or "emissions class."

Not all V5Cs show this information. If yours does not, use the online check instead.

Method 3: Estimate from Registration Date

If you cannot find the information, you can estimate based on when your car was first registered:

Petrol Cars	Diesel Cars	Euro Standard
Jan 1993 - Dec 1996	Jan 1993 - Dec 1996	Euro 1
Jan 1997 - Dec 2000	Jan 1997 - Dec 2000	Euro 2
Jan 2001 - Dec 2005	Jan 2001 - Dec 2005	Euro 3
Jan 2006 - Dec 2010	Jan 2006 - Dec 2010	Euro 4
Jan 2011 - Aug 2015	Jan 2011 - Aug 2014	Euro 5
Sep 2015 onwards	Sep 2014 onwards	Euro 6

These dates are approximate. Some cars were registered to earlier standards. Always use the DVLA check for accuracy.

Why Your Emissions Class Matters

• Clean Air Zones: Cities like Birmingham, Bristol, and Bradford charge vehicles that do not meet minimum standards.
• ULEZ: London charges £12.50 per day for non-compliant cars.
• Road tax: For cars registered before April 2017, tax is calculated based on CO2 emissions.
• Resale value: Cars with higher emissions standards are worth more on the used market.

What to Do If Your Car Does Not Meet Standards

• Scrappage schemes: Some councils offer money towards a new car if you scrap an older polluting vehicle.
• Retrofit: In some cases, you can upgrade your exhaust system to meet a higher standard.
• Switch to electric: EVs are exempt from all clean air zone charges.
• Plan your route: Avoid clean air zones if your car does not comply.
