Eight UK cities now operate Clean Air Zones, with London's ULEZ covering the largest area in Europe. Drivers caught in non-compliant vehicles face daily charges of £8-£12.50 — and PCNs of up to £180 if they don't pay. This guide covers where the zones operate in 2026, what counts as compliant and how to check before you drive.
London ULEZ covers all 33 boroughs to the M25 boundary — the largest scheme in Europe. Daily charge: £12.50. Operates 24/7 (Christmas Day excluded).
Class D Clean Air Zones (cars + LGVs + buses + taxis): Birmingham, Bristol, Sheffield. Class C (LGVs and above only): Bath, Tyneside, Bradford, Portsmouth. Glasgow operates a Low Emission Zone in the city centre. Charges range £8-£12.50/day.
Petrol cars: Euro 4 or newer (most petrol cars first registered from January 2006). Diesel cars: Euro 6 or newer (most diesels first registered from September 2015).
Motorcycles: Euro 3 or newer (most from July 2007). Vans up to 3.5t: same petrol/diesel standards as cars. Heavier vehicles have separate Euro VI requirements.
Disabled tax class vehicles, historic vehicles (40+ years), agricultural vehicles and certain specialist vehicles are usually exempt nationally. Some zones offer temporary exemptions for residents.
London's ULEZ scrappage scheme closed in 2024. Birmingham, Bradford and Portsmouth still operate exemption schemes for low-income local residents and small businesses — typically a 1-2 year grace period.
London ULEZ uses ANPR cameras throughout the zone. There's no toll booth — you pay online, by app or by phone within 3 days of driving. Auto-pay setup avoids the risk of forgetting (penalty up to £180 for non-payment).
Other zones use similar ANPR enforcement. Charges are per calendar day, not per entry — so multiple trips in one day are one charge. Don't assume rental cars are paid for; many rental contracts pass charges and admin fees to the renter.
Check any vehicle's compliance free: TfL ULEZ checker (London) or GOV.UK CAZ checker (everywhere else). Both use registration plate lookup against the DVLA Euro emissions database.
If buying a used car for use in a zone city, run the check before negotiating — non-compliance can knock £1,500-£3,000 off resale value, especially for older diesels. Don't rely on the seller's word.
London: £180 (£90 if paid within 14 days). Other zones broadly similar via TfL/local PCN regimes.
Pure EVs are. Plug-in hybrids and self-charging hybrids are compliant if they meet the Euro standard for their fuel type — most modern hybrids do.
Each zone is independently enforced. Driving from Birmingham to Bristol in a non-compliant car incurs charges in both cities.
