ULEZ Compliant Used Cars for Sale

The short answer: a used car is ULEZ compliant if it meets Euro 4 for petrol (broadly registered from 2006 onwards) or Euro 6 for diesel (roughly September 2015 onwards). Electric cars are exempt everywhere. The cars below are the ones on Autoza that clear those standards outright — typically £7,099–£16,999.

Compliance is set by emissions standard, not by age, so the dates above are a guide rather than a guarantee — some models met the standard early. We deliberately leave out cars from the diesel changeover year rather than guess: being wrong costs a buyer £12.50 a day they were not expecting. For a specific registration, use our Clean Air Zone checker or Transport for London’s official one.

Which UK zones actually charge a car

Fewer than most people assume. Most Clean Air Zones charge taxis, vans, buses and lorries but leave private cars alone. These are the ones that charge a non-compliant car:

London£13Transport for London
Bristol£9Bristol City Council
Birmingham£8Birmingham City Council

Charges verified against operator sources on 28 July 2026. Scotland runs Low Emission Zones, which ban non-compliant vehicles rather than charging them — full detail in the checker.

Compliance is not the same as cheap to run

Worth separating, because they get conflated. ULEZ compliance is about emissions standards. Vehicle tax is set by CO2 and the date of first registration. Fuel economy is a third thing again. A compliant car can still be expensive on all three, and if your driving never takes you into a charging zone, a non-compliant car costs you nothing extra. Every listing on Autoza shows a modelled annual running cost with the tax figure exact, so the comparison can be made on total cost rather than the sticker.

Frequently Asked Questions

What makes a used car ULEZ compliant?
The standard is the Euro emissions class, not the age. A petrol car generally needs to meet Euro 4, which broadly means registered from 2006 onwards, and a diesel needs Euro 6 — roughly September 2015 onwards. Fully electric cars are exempt everywhere. Those dates are a guide rather than a guarantee, because the standard is set per model at type approval and some models met it early, so always confirm a specific registration on Transport for London's own checker before you rely on it.
Which UK cities charge a non-compliant car?
Fewer than most people assume. London (£13 a day), Bristol (£9 a day), Birmingham (£8 a day). The other Clean Air Zones apply to taxis, vans, buses or lorries but not to private cars. Scotland runs Low Emission Zones instead, which ban non-compliant vehicles outright rather than charging them.
How much does a non-compliant car actually cost me?
It depends entirely on how often you drive into a zone. The London ULEZ is £12.50 a day and runs every day except Christmas Day, so a daily commute into it is a four-figure annual cost, while an occasional visit is a few pounds. If you never enter a charging zone, compliance costs you nothing — which is why buying a non-compliant car can still be sensible if your driving does not take you into one.
Is a ULEZ compliant car cheaper to run generally?
Not necessarily. ULEZ compliance is about emissions standards, not fuel economy or vehicle tax. A compliant car can still be expensive on fuel, insurance and servicing. Every listing on Autoza shows a modelled annual running cost with the vehicle tax figure exact, so you can compare a compliant car against a cheaper non-compliant one on the total rather than the sticker.
