ULEZ & Clean Air Zone Checker

Fuel type

When was it first registered?

The date of first registration is on the V5C logbook (section B). The month only matters for diesels around 2015.

Which cars are compliant?

Every UK Clean Air Zone, ULEZ and Scottish LEZ uses the same two emission standards for cars. It really is this simple.

Clean Air Zone / ULEZ compliance standards for cars
Fuel	Minimum standard	Broadly, first registered
Petrol	Euro 4	From 2006 (some late 2005)
Diesel	Euro 6	From September 2015
Hybrid (petrol)	Euro 4	From 2006
Electric	Zero emission	Always compliant

These are rules of thumb: a handful of cars sit either side of the line because of when their exact model was certified. The number that actually decides it is the vehicle's Euro emissions status, recorded at the DVLA. This tool covers cars; motorcycles (Euro 3), vans and larger vehicles have their own standards and charges.

Where cars get charged

Most Clean Air Zones only charge commercial traffic. For a private car, these are the ones that matter.

UK zones that charge non-compliant private cars
Zone	Area	Car charge
London ULEZ	Every London borough, all day, every day	£12.50 a day
Bristol Clean Air Zone	Central Bristol	£9 a day
Birmingham Clean Air Zone	Inside the A4540 ring road	£8 a day
Scottish Low Emission Zones	Glasgow, Edinburgh, Dundee and Aberdeen city centres	Penalty from £60

Bath, Bradford, Portsmouth, Sheffield and Tyneside also run Clean Air Zones, but as Class B or C zones they charge buses, coaches, taxis, vans and lorries, not private cars. Greater Manchester's scheme has been paused. Always check the exact rules for a city before you travel, at gov.uk.

Why the exact Euro standard is worth knowing before you buy

For most people the registration year settles it: a 2019 petrol is fine, a 2012 diesel isn't, and there's nothing more to think about. Where it gets expensive is the borderline: a diesel registered in 2014 or early 2015 might be Euro 5 or it might be Euro 6, and the difference is £12.50 every single day you drive it into London. Over a year of commuting that's the thick end of three thousand pounds, which is enough to change whether a car is worth buying at all.

You can't tell a Euro 5 diesel from a Euro 6 one by looking at it, and sellers don't always know. The reliable answer is the emissions standard recorded against the car at the DVLA, which is exactly what the official checkers read. A full vehicle check pulls that record for you (the registered fuel, engine and history) so a borderline car stops being a gamble. If you're weighing one up, it's the same paperwork that tells you the MOT history and road tax, so you see the whole running-cost picture at once.

And if the car checks out, our free MOT reminder service keeps an eye on the test date afterwards, so the one bit of paperwork that quietly lapses and costs you a fine doesn't catch you out.

ULEZ & Clean Air Zone: common questions

Is my car ULEZ compliant?

As a rule of thumb, a petrol car first registered from 2006 (Euro 4) and a diesel first registered from September 2015 (Euro 6) meet the ULEZ standard and pay nothing. Fully electric cars are compliant automatically. The definitive test is the vehicle's Euro emissions status on its DVLA record, which is what our £5.00 report reads back to you.

How much is the ULEZ charge?

A non-compliant car pays £12.50 a day to drive anywhere inside London's Ultra Low Emission Zone, which since August 2023 covers every London borough. It's a daily charge, so you pay once for the whole day no matter how many times you enter the zone. It is separate from the £15-a-day Congestion Charge in central London.

Which UK cities charge cars in a Clean Air Zone?

For private cars the charging zones are London (ULEZ, £12.50 a day), Bristol (£9 a day) and Birmingham (£8 a day), plus the Scottish Low Emission Zones in Glasgow, Edinburgh, Dundee and Aberdeen, which use penalties. Other zones (Bath, Bradford, Portsmouth, Sheffield, Tyneside) only charge buses, taxis, vans and lorries, not cars.

Do electric and hybrid cars pay the ULEZ charge?

Fully electric cars never pay: no exhaust, no charge. Hybrids depend on the engine: almost all are petrol, so they follow the petrol Euro 4 rule and any hybrid from 2006 is fine. There is no separate "hybrid" exemption; it comes down to the same Euro standard as everything else.

How do I know my car's exact Euro standard?

The Euro emissions status is recorded against the vehicle at the DVLA, and it's the number the official checkers use. Our £5.00 vehicle report pulls it straight from the record, along with the fuel type, engine and full history, so you can settle a borderline car for certain rather than guessing from the year.
