Is your vehicle ULEZ-compliant?
Pick your fuel and year. We check compliance against London ULEZ, the seven English Clean Air Zones, and all four Scottish Low Emission Zones.
Our check uses year-of-registration to infer Euro standard. The official TfL/DEFRA tools query DVLA by registration plate for an exact answer — always confirm there before driving in.

How it works
Petrol: Euro 4 = compliant
Almost all petrol cars first registered from January 2006 onwards meet Euro 4 and are ULEZ-compliant. Some 2005-built ones do too. Older petrol cars typically pay the daily charge.
Diesel: Euro 6 = compliant
Diesel cars need Euro 6, which became mandatory from September 2015. Earlier "Euro 5" diesels (2011-2015) are NOT compliant for London ULEZ — a common surprise for owners of late-Euro-5 cars.
Electric and hydrogen
Always compliant, anywhere. Pure EVs and hydrogen fuel-cell vehicles pay zero in every UK CAZ/LEZ, though they still pay TfL's congestion charge in central London where applicable.
Scottish LEZs are stricter
Glasgow, Edinburgh, Aberdeen and Dundee LEZs apply the same emissions test but cars ARE included (English class C/B zones often exempt cars). Penalty starts at £60 and doubles for each repeat in the same calendar month.
London ULEZ is 24/7 and pan-London
Since 29 August 2023, ULEZ covers all of Greater London (inside the M25). It applies 24 hours, 365 days. Daily charge is £12.50 for non-compliant cars and vans.
How to check officially
Use TfL's ULEZ vehicle checker (tfl.gov.uk/ulez) for London — it queries DVLA by registration. For other CAZs, use gov.uk/clean-air-zones — they all share the same DVLA-backed compliance database.
