London is one of the most expensive cities in the UK to travel by taxi, but the price you pay is far from fixed. Where you start, the time of day, the type of vehicle and whether you book ahead or hail on the street all move the number. This guide breaks down the levers that actually make a difference.
Prices mentioned here are illustrative estimates and will vary — the licensed taxi partner always sets the final fare.
Black cab or private hire?
London has two very different licensed options, and choosing the right one is the single biggest cost decision.
- Black cabs (hackney carriages) run on a regulated meter you can’t know in advance. You can hail them on the street or pick them up at a rank, which is convenient, but a long or slow journey can climb quickly because you pay for time as well as distance.
- Private hire (minicabs) must be booked in advance through a licensed taxi partner and can usually quote a price up front. For longer or predictable journeys — an airport run, a cross-town trip — a pre-agreed price is often cheaper and removes the meter anxiety.
If you want certainty, comparing a private-hire estimate first is the way to go. If you’re in a hurry in the centre and a cab is right there, the black-cab convenience may be worth it. For airport runs specifically, see our Heathrow to London and Heathrow taxi guide for typical fares and timings.
Timing is money
London traffic is the enemy of a cheap fare. A few timing tricks help:
- Avoid the 08:00–09:30 and 17:00–18:30 peaks where you can — a crawl through central London adds time-based cost and slows private-hire turnaround.
- Late evening runs are often quicker (and therefore cheaper per mile), though a night surcharge can apply between roughly 22:00 and 06:00.
- Build in buffer for events — a match at Wembley or a concert at the O2 spikes demand across whole swathes of the city.
Watch the zones and charges
Central London journeys can attract the Congestion Charge and, for older vehicles, ULEZ charges. Licensed taxi partners handle these differently, so ask how they’re applied when you book — it can change the total more than the mileage does.
Compare before you commit
The easiest saving is also the simplest: get an estimate for your exact journey before booking, rather than accepting the first number offered. Small changes — a slightly different pickup point, a saloon instead of an executive car, an off-peak departure — add up.

The bottom line
- Book private hire ahead for a quoted price on longer trips.
- Travel off-peak where you can.
- Choose the smallest vehicle that fits your group and luggage.
- Ask how the Congestion Charge and ULEZ are handled.
- Always compare an estimate first.
