Free Car ULEZ Check

The Euro emission standard, fuel type and engine details used to determine compliance come from official DVLA vehicle records — the same source used for every other check on this site. The compliance rules themselves — which standards qualify, what the daily charge is, and exactly where the zone boundary sits — are set and published by Transport for London, not the DVLA, at tfl.gov.uk/ultra-low-emission-zone. What we do here is apply TfL's published Euro 4 (petrol) and Euro 6 (diesel) thresholds to your specific vehicle's DVLA-recorded details, so you get a direct compliant/non-compliant answer rather than having to cross-reference the two yourself.

ULEZ is a specific scheme covering Greater London and run exclusively by Transport for London. Several other UK cities run their own, separate schemes under the broader Clean Air Zone framework — Birmingham, Bristol, Sheffield, Bath, Portsmouth and others each have their own boundaries, charges, and sometimes different vehicle categories that are charged. The underlying idea is similar across all of them (charging older, more polluting vehicles more to enter defined areas), and the Euro standard thresholds are often comparable, but the charges, exemptions, and exact geographic boundaries genuinely differ between cities. If you're driving into any of these areas, it's worth checking that specific city's own scheme directly rather than assuming ULEZ rules apply everywhere.

Not directly, and it's a common point of confusion because both are influenced by the same underlying thing — a vehicle's emissions. ULEZ and vehicle tax are entirely separate systems, run by different authorities (TfL for ULEZ, DVLA for tax), assessed against different criteria, and enforced independently of each other. In practice this means a car can be fully taxed, legally MOT'd, and completely road-legal everywhere in the UK, while still being ULEZ non-compliant and liable for the daily charge specifically within Greater London. Check your tax status and your ULEZ compliance as two separate questions, because a clean result on one tells you nothing about the other.

The moment to check is before you buy, not after you've already been charged. As a general rule of thumb, most petrol cars registered from 2006 onwards and most diesel cars registered from September 2015 onwards meet the required Euro standards — but treat this as a starting point for checking, not a guarantee, since standards were phased in gradually and some individual models fell either side of the general pattern depending on their specific engine. If you regularly drive in or near London, or the car you're buying will be used there, verify the specific vehicle's Euro standard directly rather than relying on the registration year alone. Combining this ULEZ check with a full DVLA check gives you the engine and emissions detail needed to be confident either way before you commit to buying.
