Do I have to pay the ULEZ charge myself as a taxi passenger?

No. TfL charges the registered vehicle, not the passenger. You'd only ever see a cost if a private hire operator chooses to build it into the fare they quote you — it is never billed to you separately by TfL.

Are black cabs exempt from ULEZ?

Yes. London-licensed black cabs are exempt from the ULEZ charge regardless of their engine, because they're purpose-built, wheelchair-accessible vehicles held to their own licensing standards.

Are private hire cars and minicabs exempt from ULEZ?

Not automatically. A private hire vehicle only avoids the charge if it meets the emissions standard itself (broadly Euro 4 petrol or Euro 6 diesel, or electric/plug-in hybrid). Most modern private hire fleets clear this easily.

What area does the ULEZ cover in 2026?

The whole of Greater London — all 32 boroughs, out to the boundary with Buckinghamshire, Essex, Hertfordshire, Kent and Surrey — since the zone was expanded on 29 August 2023. A few roads just outside the boundary, such as parts of Dartford, Watford and Caterham, sit outside it.

Is the ULEZ charge the same as the Congestion Charge?

No, they're separate. ULEZ is about a vehicle's emissions standard and covers all of Greater London, 24/7 (except Christmas Day). The Congestion Charge is about being in a much smaller central London zone during weekday daytime hours, regardless of emissions. A journey can be liable for both.

Will I ever get an unexpected ULEZ charge on a Hail A Taxi booking?

Your fare is shown as a fixed, all-in price before you book, so there's nothing added afterwards. Our network runs modern vehicles that are comfortably within the ULEZ emissions standard, so this is not something riders need to plan around.

Does the ULEZ Charge Apply to Taxis in London? (2026 Guide)

If you've booked a cab in London recently, you've probably seen the letters ULEZ somewhere and wondered whether it's about to land on your fare. It's a fair question — the Ultra Low Emission Zone now covers all 32 London boroughs, it runs every single day of the year bar Christmas Day, and the penalty for getting caught out is steep. This guide covers what the ULEZ actually is, exactly who it charges — drivers, operators, or passengers — and how it's different from the London Congestion Charge, which is a separate fee entirely.

What is the ULEZ, and where does it cover?

The Ultra Low Emission Zone is a daily charge on older, more polluting vehicles driving in London, brought in to cut air pollution. Since 29 August 2023 it has covered the entire Greater London area — right out to the boundary with Buckinghamshire, Essex, Hertfordshire, Kent and Surrey — not just central London. A handful of roads just outside that boundary, such as parts of Dartford, Watford and Caterham, sit outside the zone, but almost anywhere you'd actually be travelling to or from in London is inside it.

It operates 24 hours a day, every day of the year except Christmas Day. There's no "evenings and weekends are free" rule here the way there is with the Congestion Charge — if your vehicle doesn't meet the standard, it applies at 3am on a Sunday just as much as 9am on a Tuesday.

How much is the ULEZ charge?

For a non-compliant car, motorcycle or small van, the daily charge is £12.50, covering every journey made that day regardless of how many times the vehicle crosses the boundary. Lorries, coaches and other larger vehicles that don't meet the standard pay considerably more under a separate scheme. A vehicle only needs to meet a reasonably modern emissions standard to be exempt — broadly, Euro 4 for petrol engines (most petrol cars made from roughly 2006 onwards) and Euro 6 for diesel (most diesel cars made from around 2015 onwards). Fully electric vehicles and most plug-in hybrids are exempt outright.

So does ULEZ apply to taxis and private hire cars?

This is where it genuinely splits in two, and it's the bit most guides gloss over:

Black cabs (London-licensed hackney carriages) are exempt from ULEZ charges altogether, regardless of their engine. The reasoning TfL has given is that they're purpose-built, wheelchair-accessible vehicles held to their own strict licensing and testing standards.
Private hire vehicles (minicabs, and the cars behind most app-based and pre-booked taxi services, including ours) are not blanket-exempt. If the specific car assigned to your journey doesn't meet the emissions standard above, the daily charge applies like it would for any other vehicle on the road.

In practice, this rarely bites riders booking a modern, mainstream private hire service. The vast majority of cars actively working as private hire vehicles in London today are well within the last decade and comfortably clear the Euro 4/Euro 6 bar — it's older, privately owned cars that this was really aimed at. But it's the reason you'll occasionally see a "ULEZ charge" line appear on a minicab receipt: unlike a black cab's regulated fare, a private hire operator is free to pass the cost on to the passenger when it genuinely applies.

ULEZ vs the Congestion Charge: don't mix them up

These are two completely separate TfL schemes, and a journey can be liable for both at once:

ULEZ is about the vehicle's emissions standard, covers the whole of Greater London, and runs 24/7, every day except Christmas Day.
The Congestion Charge is about being in central London at all (it doesn't care what your exhaust emits), covers a much smaller central zone, and only applies on weekdays during set daytime hours.

A journey from somewhere like Croydon into the City on a weekday afternoon in a non-compliant car could, in theory, pick up both. A compliant car making the same trip would only ever be liable for the Congestion Charge, since that one isn't about emissions at all.

What this actually means when you book a taxi

None of this is charged to you as a passenger directly by TfL — you're never going to get a penalty notice in the post for sitting in the back of someone else's car. Any cost only ever reaches you if the operator chooses to pass it on in the fare they quote. That's exactly why a fixed, all-in price shown before you book matters: whatever applies to a given journey is either already reflected in the number you see, or it simply doesn't apply, because the vehicle is compliant. Either way, there's no line item that shows up for the first time after you've already got in the car.

If you're planning a journey across London — an airport transfer, a cross-city run, or anything in between — get your fixed quote up front and you won't need to think about ULEZ, the Congestion Charge, or anything else that might otherwise turn up as a surprise.
