Heathrow Airport sits inside London's Ultra Low Emission Zone, which surprises some travellers who assume ULEZ is a central-London-only rule. Here's what it actually means for your taxi or minicab fare.
The quick answer
Heathrow has been inside the ULEZ since it expanded to cover all of Greater London on 29 August 2023. Licensed black cabs are exempt from the daily £12.50 ULEZ charge, and private hire minicabs are generally unaffected too, since operators run ULEZ-compliant fleets. The London Congestion Charge, by contrast, does not reach Heathrow at all; it applies only to central London.
ULEZ and Heathrow: the basics
The Ultra Low Emission Zone now covers every London borough, including the London Borough of Hillingdon, where Heathrow sits. Non-compliant vehicles driving into the zone pay a daily charge of £12.50, which applies 24 hours a day, every day except Christmas Day. For a private car driving yourself to the airport in an older, more polluting vehicle, this is a genuine cost to check before you travel.
Does this affect your taxi fare?
For most passengers, no additional charge shows up on the fare, for two main reasons:
- London black cabs (licensed taxis) are exempt from ULEZ, provided the vehicle is no more than 12 years old, because they're purpose-built, wheelchair-accessible vehicles under a different regulatory scheme.
- Private hire minicabs are not automatically exempt, but the vast majority of licensed operators run ULEZ-compliant vehicles (petrol cars meeting Euro 4 standards or newer, diesel meeting Euro 6 or newer) as standard, since non-compliant vehicles would cost the operator money on every single London journey. Reputable pre-booked operators build any such cost into their standard pricing rather than passing it on as a separate line item.
In practice, this means a pre-booked, fixed-price transfer to or from Heathrow should already reflect any ULEZ considerations in the quoted fare, with nothing extra to pay on the day. If you're unsure, it's worth asking your operator directly when you book.
What about the Congestion Charge?
The separate London Congestion Charge zone covers only central London and does not extend to Heathrow. Unless your journey specifically routes through the Congestion Charge zone itself, for example travelling right into the West End at a chargeable time, it has no bearing on a standard Heathrow transfer. Current charge amounts and operating hours are set by Transport for London, so check tfl.gov.uk for the latest figure before assuming a rate.
If you're driving yourself
If you're driving your own car to Heathrow rather than taking a taxi, check whether your vehicle is ULEZ-compliant using the checker on tfl.gov.uk before you travel, since the daily charge applies regardless of how briefly you're in the zone. This is separate from any Heathrow drop-off or parking charge; see our drop-off page and parking page for those costs.
The straightforward option
If you'd rather not think about any of this, a pre-booked transfer with 247 UK Airport Taxi fixes the price before you travel, with your flight tracked, so ULEZ, traffic and drop-off charges are all already reflected in the fare you're quoted. See our taxis page for current pricing.
