ULEZ & Clean Air Zones: Will Your Car Be Charged?
Which UK cities charge older cars to drive in, how to check if your car is ULEZ compliant, and what you’ll pay if it isn’t — London ULEZ, Clean Air Zones and Scotland’s LEZs explained.
If you drive into a big UK city in an older car, there’s a growing chance you’ll be charged for it — or fined outright. London’s ULEZ, England’s Clean Air Zones and Scotland’s Low Emission Zones all work slightly differently, which catches a lot of drivers out. Here’s the simple version.
The quick rule of thumb
Almost every UK emissions zone uses the same two standards:
- Petrol cars: need to meet Euro 4 — broadly, cars first registered from 2006 onwards (many from 2001–2005 also qualify).
- Diesel cars: need to meet Euro 6 — broadly, cars first registered from September 2015 onwards.
Fully electric cars are compliant everywhere. Hybrids are judged on their petrol or diesel engine like any other car — being a hybrid doesn’t automatically exempt you.
London ULEZ
The Ultra Low Emission Zone now covers all London boroughs — not just the city centre — and runs 24 hours a day, every day except Christmas Day.
- Charge for non-compliant cars: £12.50 per day
- Penalty for not paying: £180 (halved if paid within 14 days)
- Standards: Euro 4 petrol / Euro 6 diesel
Check any reg on TfL’s official tool: tfl.gov.uk/modes/driving/check-your-vehicle. That answer is definitive — if TfL says you’re compliant, you pay nothing.
Clean Air Zones in England
Several English cities run Clean Air Zones (CAZ), but here’s the bit most people miss: the zones come in classes A to D, and only class D zones charge private cars. The rest only charge taxis, buses, coaches, vans or lorries.
- Birmingham (Class D): non-compliant private cars pay around £8/day
- Bristol (Class D): around £9/day
- Bath, Bradford, Sheffield, Portsmouth, Tyneside: private cars are not charged (commercial vehicles are)
Check any zone and any reg on the official government checker: gov.uk/clean-air-zones.
Scotland’s Low Emission Zones
Glasgow, Edinburgh, Dundee and Aberdeen run LEZs — and these work differently. There’s no daily charge option: non-compliant cars are simply banned from the zone, and driving in anyway means a £60 penalty that doubles with each repeat offence. Same Euro 4 petrol / Euro 6 diesel standards apply.
Oxford’s Zero Emission Zone
Oxford runs a small city-centre Zero Emission Zone where even compliant petrol and diesel cars pay a daily charge — only fully electric vehicles drive free. It currently covers just a handful of streets, but it’s a sign of where things are heading.
How to avoid a nasty surprise
- Check your car’s Euro status — on your V5C logbook, or via the checkers above.
- Before driving into any major city, spend 30 seconds on the official zone checker.
- If you’re charged, pay promptly — most zones allow payment up to midnight on the third day after travel, and penalties are far higher than the charge.
- Buying a used car? Factor compliance into the price — a non-compliant diesel is worth notably less if you live near a zone.
Frequently asked questions
How do I know if my car is ULEZ compliant?
The quick rule: petrol cars need to meet Euro 4 (broadly, first registered from 2006 onwards) and diesels need Euro 6 (broadly, from September 2015 onwards). Fully electric cars are compliant everywhere. For a definitive answer, check your reg on TfL's official tool at tfl.gov.uk — if TfL says you're compliant, you pay nothing.
How much is the ULEZ charge and the penalty for not paying?
Non-compliant cars pay £12.50 per day to drive anywhere in the ULEZ, which now covers all London boroughs, 24 hours a day, every day except Christmas Day. Forget to pay and the penalty is £180, halved if paid within 14 days. Most zones let you pay up to midnight on the third day after travel.
Do Clean Air Zones outside London charge private cars?
Mostly no — this is the bit most drivers miss. English Clean Air Zones come in classes A to D, and only class D zones charge private cars: Birmingham (around £8/day) and Bristol (around £9/day). Bath, Bradford, Sheffield, Portsmouth and Tyneside only charge taxis, buses, coaches, vans or lorries. Check any zone and reg at gov.uk/clean-air-zones.
Are hybrids exempt from ULEZ and Clean Air Zones?
No — being a hybrid doesn't automatically exempt you. Hybrids are judged on their petrol or diesel engine like any other car, so a hybrid still needs to meet Euro 4 (petrol) or Euro 6 (diesel). Only fully electric cars are compliant in every UK emissions zone — and in Oxford's small Zero Emission Zone, only EVs drive free.
