The Ultra Low Emission Zone (ULEZ) is the most important single environmental rule affecting London private hire drivers. Since the August 2023 expansion, ULEZ covers all London boroughs and operates 24 hours a day, every day except Christmas Day.
Vehicle standards
- Petrol cars and small vans: generally compliant if Euro 4 or newer.
- Diesel cars and small vans: generally compliant if Euro 6 or newer.
- Motorcycles and similar: generally compliant if Euro 3 or newer.
Use TfL's free vehicle checker to confirm your specific vehicle. Compliance is decided by the vehicle's emissions standard, not its registration year alone.
Daily charge for non-compliant vehicles
If your vehicle does not meet ULEZ standards, you must pay the daily ULEZ charge to drive anywhere in the zone. Miss the payment and you'll face a Penalty Charge Notice. Auto Pay handles ULEZ as well as the Congestion Charge.
Why it matters for PHV operators
Non-compliance erodes your earnings fast. A non-compliant car driven five days a week racks up serious daily fees. Most full-time PHV drivers either own a compliant vehicle, lease one through their operator, or transition to electric.
Going electric
Battery electric vehicles are zero-emission and currently outside the ULEZ daily charge. Charging access varies by borough — check public charging coverage on your usual routes before committing.

If you only have a fortnight to prepare, split your time into three blocks. Spend the first few days reading any official handbook or syllabus straight through — don't try to memorise yet, the goal is familiarity. Move on to topic-by-topic revision, focusing on the areas you found least intuitive on the first read. In the final week, switch to timed mock tests under exam conditions; mark every paper ruthlessly and read every explanation, including for questions you got right by guessing. Most candidates improve by 8–12 marks between their first and third mock simply by closing knowledge gaps this way.
Common myths to ignore
Three myths trip up more candidates than any single topic. The first is that "if I sit enough mocks, I'll spot the real questions on test day" — modern UK exam banks contain hundreds of items and the question you see on the day will probably be brand new to you. The second is that you can cram the night before; most assessments reward calm focus more than recent recall, and tired candidates make basic mistakes. The third is that the pass mark is the only thing that matters: aiming for a comfortable buffer of 5–10 marks above the threshold is the single best insurance against an unlucky paper.
What to do on test day
Plan to arrive 15–20 minutes early with valid photo ID — usually a UK driving licence or passport — and any booking confirmation you've been emailed. Eat something light beforehand, drink water but not so much that you'll need a comfort break mid-paper, and silence your phone before you walk through the door. Read every question twice, flag anything you're unsure of, and never leave a blank — there's no negative marking on the assessments most readers of this site sit, so a considered guess is always better than no answer at all.
