Split four ways, a Heathrow taxi to central London works out at roughly £11-£33 per person, against a £45-£130 total fare depending on whether you take a pre-booked minicab or a metered black cab. For a group of three or four with luggage, that's often cheaper than separate Elizabeth line, Tube or coach tickets once you add up every ticket and factor in getting bags on and off trains. Figures checked against Heathrow Airport Guide's own taxis page, 2026.
The maths: taxi fare split by group size
Using the typical Heathrow-to-central-London ranges (£45-£75 for a pre-booked minicab, £75-£130 for a metered black cab):
| Group size | Minicab (£45-£75) per person | Black cab (£75-£130) per person |
|---|---|---|
| 1 | £45-£75 | £75-£130 |
| 2 | £23-£38 | £38-£65 |
| 3 | £15-£25 | £25-£43 |
| 4 | £11-£19 | £19-£33 |
The more people you're travelling with, the more a taxi closes the gap on, or beats, public transport, especially once luggage, step-free access and the hassle of changing between the Elizabeth line and the Tube or a bus are factored in rather than just the ticket price.
When does the Tube or Elizabeth line still win?
For a solo traveller or a pair with light luggage, public transport is usually still cheaper and, on the Elizabeth line, often comparably fast into central London. The calculation shifts once you're three or more people, carrying hold luggage, or travelling somewhere that needs a change of train or a final bus or walk at the other end, since each of those adds friction a taxi avoids entirely.
Does a bigger car change the per-person maths?
If your group needs an estate, MPV or minibus rather than a standard saloon, the total fare is higher than the saloon ranges above, but the per-person cost can still work out favourably once you're five or six people splitting one vehicle rather than buying five or six individual train tickets. Request the right vehicle size when you book rather than at the rank, since larger vehicles are in more limited supply and may need to be arranged in advance.
Pre-booked vs rank for a group
For a group, a pre-booked minicab has two advantages beyond the lower headline fare: the price is fixed and split cleanly before you travel (useful if you're dividing costs with people who aren't paying the driver directly), and the car is confirmed for your exact flight rather than depending on rank queue length when several flights land together. Our recommended pre-booked operator is 247 UK Airport Taxi, part of the Tick Taxi group, which fixes the price before you travel and tracks your flight so a late landing never changes what you owe. We recommend a transport partner and may earn a referral fee; it never changes the price you pay.
A metered black cab at the rank remains the simpler option if you land without a booking and want a car immediately, and most black cabs comfortably seat four to five passengers with luggage.
Worked example: a family of four
A family of four landing at Heathrow with a few checked bags, heading to central London:
- Minicab, pre-booked: £45-£75 total, or roughly £11-£19 per person
- Black cab from the rank: £75-£130 total, or roughly £19-£33 per person
- Four Elizabeth line tickets: priced per journey and per person, so compare the total against the taxi fare before assuming the train is automatically cheaper, particularly once you add the time and hassle of moving four sets of luggage through two sets of barriers
For many families, a pre-booked minicab ends up close to, or cheaper than, four individual rail fares once the full group and luggage picture is considered, while also being door-to-door.
What this doesn't cover
This page compares taxi fares split across a group against the headline cost of going by road; it doesn't price every public transport combination for every destination, since onward fares vary by exact station and ticket type. For a straight look at rail options, see our public transport page, and check current Elizabeth line, Heathrow Express or Tube fares directly before comparing against the taxi figures here.

Frequently asked questions
How much does a Heathrow taxi cost split between four people?
Roughly £11-£19 per person for a pre-booked minicab (£45-£75 total), or £19-£33 per person for a metered black cab (£75-£130 total).
Is a taxi from Heathrow cheaper than the train for a group?
Often, yes, for three or more people with luggage, once you add up individual train tickets and the hassle of changing trains or buses. For one or two people travelling light, rail is usually still cheaper.
Can a standard taxi fit a family of four with luggage at Heathrow?
Most black cabs and standard minicabs comfortably seat four passengers with luggage; for more passengers or extra bags, request a larger vehicle when you book.
Is it cheaper to pre-book a minicab or use the black cab rank for a group?
A pre-booked minicab is usually cheaper and fixes the price before you travel, which also makes splitting the cost between group members simpler.
Does booking a bigger vehicle cost proportionally more per person?
Not necessarily. A larger vehicle costs more in total, but splitting it between five or six people can still beat buying that many individual train tickets, particularly with luggage.
