What is ULEZ?

The Ultra Low Emission Zone (ULEZ) is a London-wide scheme charging older, more polluting vehicles a daily fee to drive within the zone. Petrol cars generally need to meet Euro 4 standards and diesels Euro 6 to avoid the charge. Operated by Transport for London using number-plate cameras, ULEZ expanded to all London boroughs in August 2023. It is separate from the Congestion Charge, which applies to central London regardless of emissions.
