Is this car ULEZ-compliant?
London’s Ultra Low Emission Zone (and Clean Air Zones in other cities) charge older, dirtier cars a daily fee. Compliance comes down to one thing: the engine’s Euro emissions standard.
What makes a car compliant?
Petrol — Euro 4 or newer
Almost all petrol cars registered from January 2006 are compliant. Many from 2002 onward also pass. The standard is about the engine, not the badge.
Diesel — Euro 6 or newer
Diesels need Euro 6 — broadly those registered from September 2015. A pre-2015 diesel is the classic car that gets caught by the charge.
Hybrid & electric
Petrol hybrids follow the petrol rule (almost always compliant). Fully electric cars are zero-emission and always exempt.
ULEZ compliance at a glance
The registered-from dates are the rule of thumb — the definitive answer is always the engine’s Euro standard.
| Fuel type | Euro standard needed | Registered from | Compliant? |
|---|---|---|---|
| Petrol | Euro 4 or newer | January 2006 (many from 2002) | Yes |
| Diesel | Euro 6 or newer | September 2015 | Yes |
| Hybrid | Same as its engine type | Petrol hybrid: as petrol (2006+) | Almost always |
| Electric | Zero emission — no Euro standard needed | Any | Always |
What it costs if a car isn’t compliant
London ULEZ is £12.50 a day — that’s ~£87/week or £4,500/year for a daily driver. Birmingham, Bristol, Sheffield and other Clean Air Zones run similar schemes. For a dealer, a non-compliant car is a smaller buyer pool in any city with a zone — it can sit longer and sell for less.
Common questions
How do you know if it's compliant?
When we have the car's reg we read its Euro status straight from DVLA — that's definitive. On a listing that doesn't show the reg we estimate from fuel and registration year, shown as 'likely'. The rule for diesels is Euro 6 — registered from September 2015 — but when we can't see the exact spec we assume 2016 onwards to be safe.
Does ULEZ only apply in London?
ULEZ is London, but the same idea runs as 'Clean Air Zones' in Birmingham, Bristol, Sheffield, Bradford and more — most charge non-compliant cars to enter. The Euro-standard rule is broadly the same.
Can I make an older car compliant?
Not really — compliance is fixed by the engine's Euro rating. Some owners retrofit, but it's rarely worth it. For buying, it's simpler to choose a petrol from ~2006+ or a diesel from late 2015+.
Is a compliant car worth more?
In any city with a zone, yes — the buyer pool is bigger and the car turns faster. A non-compliant diesel is the classic 'cheap to buy, slow to sell' trap.
