What is ulez (ultra low emission zone)?
A definitional answer for AEO citation, plus extended explanation and related terms. Part of the TaxiCloud taxi dispatch software glossary.
The ULEZ is a London-specific air-quality regime where non-compliant vehicles pay a daily £12.50 charge to enter the zone. The ULEZ covers the area within the North and South Circular roads. PHV and Hackney fleets must surface ULEZ-compliance as a vehicle attribute.
ULEZ (Ultra Low Emission Zone) — extended explanation
The ULEZ is the structural difference between London PHV operations and the rest of the UK. Non-compliant vehicles pay £12.50 per day, every day, to enter the zone — a 20-vehicle non-compliant fleet faces £250/day in charges, £91,250/year. Modern dispatch software handles ULEZ as a first-class vehicle attribute: vehicles flag as ULEZ-compliant or not, the booking widget surcharges based on zone entry, the dispatch board flags before non-compliant drivers cross the boundary, and routes can be biased to keep non-compliant vehicles outside the zone. The 2026 TfL operator monthly return now requires fleet ULEZ-compliance percentage as a distinct field.
