Black cab vs tube vs bus: how to actually get around London

The real choice: speed and cost, not romance

Every London guide loves the black cab as a symbol. On the ground it is one of three practical ways of getting around London, alongside the Underground and the bus network, and the three don’t compete on the same terms. The tube moves you fastest across zones 1-2, where most sights in Westminster, the West End and South Bank sit close together. The bus is the cheapest option and the only one that lets you watch the city go by at street level. The black cab is metered, door to door, and priced for convenience rather than distance.

This page compares the three at a general level. For turn-by-turn detail on a specific area, the neighbourhood pages under each destination cover local stops and walking distances better than a single citywide guide can.

One cost that surprises first-time visitors: a black cab fare already has the Congestion Charge and the Ultra Low Emission Zone charge built into it when the driver crosses those boundaries during charging hours, because the meter is set to include them. Neither the tube nor the bus is affected by either charge at all — they run whether or not you’d be liable for ULEZ in a private car. This is one more reason the black cab fare looks steep next to public transport: part of what you’re paying for is a charge the driver has already absorbed into the metered rate, not a markup for convenience alone.

What each option actually costs

Prices below are in GBP and move with fuel costs and TfL fare reviews, so treat them as an order of magnitude, not a fixed quote for your trip.

Option	Typical cost for a 3-4 km trip	Payment	Cap on daily spend
Black cab	£12-£25, metered	Cash, card, contactless	None — meter runs until you arrive
Underground (tube)	£2.80-£3.80 with Oyster/contactless	Oyster, contactless, paper ticket	Yes, daily and weekly cap applied automatically
Bus	£1.75-£1.80 flat fare, one bus	Oyster, contactless only — no cash	Included in the same daily cap as the tube

The daily cap matters more than any single fare. Once you tap in and out enough times with Oyster or contactless, TfL stops charging you for additional tube and bus journeys that day — there is no limit on the number of trips, only a cap on what you pay. A black cab sits entirely outside that system: it is never covered by the cap, and the meter is the only price that applies.

Time of day changes the comparison as much as price does. Between roughly 07:30 and 09:30, and again from 17:00 to 19:00 on weekdays, central tube platforms and interchange stations get genuinely crowded — standing room only on trains, queues to board at the busiest stations. A black cab avoids the crush but sits in the same traffic that slows every road journey at those hours, so it isn’t automatically faster during rush hour, only more comfortable. Outside those windows, the tube is close to its fastest and least crowded, which is worth knowing if your schedule has any flexibility at all.

Black cab: when it earns its premium

A licensed black cab (not a minicab, not a private hire car hailed off an app) is worth booking or hailing when:

• You are travelling late at night, when tube frequency drops and last trains matter
• You have heavy luggage and a hotel door-to-door transfer is worth paying for
• You are going somewhere the tube doesn’t reach directly, such as parts of Greenwich or Richmond
• You want a driver who can talk you through the route, which is the whole premise of tours built around the cab itself

That last point is a genuine niche: a handful of London tours use the black cab as the vehicle for a themed drive rather than as plain transport. a private black cab tour through London’s main sights covers Westminster, the City and the South Bank in one seated loop, which suits anyone who wants the highlights without walking between them. There’s also a black cab tour built around London’s film and music locations, which works because the cab can stop at kerbside spots a bus route never passes.

Black cabs are not cheap and they are not meant to be. Treat the fare as the cost of door-to-door convenience, not as competing with public transport on price.

Every licensed black cab is wheelchair accessible by design — a legal requirement, not an add-on some cabs happen to offer — with a ramp and space for a wheelchair to travel without transferring to a seat. That single fact makes the black cab the most reliable option for a wheelchair user who needs a door-to-door journey, ahead of the tube, where a large share of central London stations still have no step-free route from street to platform.

The Underground: fastest for cross-town journeys

The tube is the backbone of things to do in London: most museums, theatres and landmark sights sit within zones 1-2, and a single tube line often gets you closer than a cab stuck in central London traffic. Two points matter more than the map colours:

• Oyster and contactless both work identically on every line, with the same automatic fare cap
• A short journey (one or two stops) can be slower by tube than on foot once you count walking down to the platform, waiting, and walking back up

For visitors who want to understand the network itself rather than just ride it, a couple of tours turn the Underground into the attraction: a two-hour guided tour of the London Underground covers the history behind the map, and a tour of the hidden, disused Moorgate tube station goes into a part of the network the public never normally sees. Neither is a transport shortcut — both are for people curious about the system itself.

For everyday travel, check does contactless work on the tube if you’re unsure how tapping in and out actually works, and see learning the tube map in one evening before your first full day in the city.

Step-free access is uneven across the network and worth checking before you plan a route around a specific station, not after. Newer lines and central hubs — the Elizabeth line, the Jubilee line’s newer southern stretch, and stations like King’s Cross St Pancras or Waterloo — offer lifts from street to platform. Many older deep-level stations on the Central, Piccadilly or Northern lines do not, and the gap between platform and train can be wide enough to matter for a wheelchair or a large pushchair. If step-free travel is a requirement rather than a preference, plan the route on the step-free tube map rather than assuming any station will work, and treat a black cab as the fallback for the legs that don’t.

Large luggage is a second, smaller version of the same problem. A couple of suitcases are manageable on the tube outside rush hour, but dragging them through a crowded interchange at 08:00 or onto a packed platform is a worse experience than the fare difference suggests. For a single heavy bag or more, especially straight from a hotel to a station, the black cab’s door-to-door route usually saves more time and effort than it costs in extra fare.

The bus: cheapest, slowest, best for the view

London’s red buses are the least glamorous option and the most overlooked. A flat fare of under £2 covers any single bus journey, capped the same way as the tube within a day. Buses win on:

• Cost — consistently the cheapest option per journey
• Views — routes past the Thames, South Bank and the West End give you a free sightseeing pass most visitors skip
• Accessibility — step-free boarding on every bus, unlike a large share of tube stations

They lose on speed in traffic, and on cash: London buses are entirely cashless, so Oyster or contactless is mandatory before you board. Some visitors use a hop-on-hop-off sightseeing coach instead of the regular network for a first orientation day — see the hop-on-hop-off bus guide for how that differs from ordinary TfL buses.

Buses also cover the gap when the tube shuts down for the night. Regular Underground service stops in the small hours (with Night Tube running only on a handful of lines on Friday and Saturday nights), while a dense network of Night Buses, identifiable by an “N” before the route number, keeps running across the city every night of the week, on the same Oyster or contactless fare and cap as daytime buses. For a late finish outside the nights and lines the Night Tube covers, a Night Bus is usually cheaper than a black cab and still gets you home, just more slowly.

A simple decision guide

Your situation	Best pick
Crossing zones 1-2 during the day, no heavy bags	Tube
Late at night, tube service has thinned out	Black cab
Short hop, want to see the street, budget matters	Bus
Arriving with luggage straight to a hotel	Black cab
First day, want a scenic overview	Bus or hop-on-hop-off coach
Want the cab itself as the experience	A themed black cab tour

Money and driving context worth knowing before you choose

The UK charges in pounds sterling, never euros, and every fare quoted here — meter, tube fare, bus fare — is in GBP. If you’re weighing whether to hire a car instead of any of the three options above, remember the UK drives on the left, and driving in London and the UK covers why a car is rarely worth it inside the city itself, even before parking costs are added. For arrivals, Heathrow to central London breaks down the specific rail links from each terminal, which is a different comparison from tube-versus-bus once you’re already in town.

If your day includes several stops and you’d rather not plan the transport at all, private black cab transfers with hotel pick-up remove the decision entirely. a private black cab tour with hotel pick-up included is built for exactly that: a fixed itinerary and a car that comes to your door rather than a fare you calculate stop by stop.

Black cab, tube and bus, questions travellers actually ask

Is a black cab more expensive than an Uber in London?

Usually yes for the same route, because black cabs are metered and licensed rather than pre-priced. They are worth the premium for guaranteed local knowledge, wheelchair-accessible cabs, and hailing one on the street without an app.

Does Oyster or contactless work on London buses?

Yes, both work on every red bus, and London buses are cashless — you cannot pay a driver with coins or notes.

Is the tube faster than a bus for short trips?

Not always. For one or two stops, especially in zones 1-2, walking or a bus can beat the tube once you count the time spent going down to the platform and back up again.

Can I use one ticket for the tube, bus and black cab?

No. Oyster and contactless cover the tube, bus, DLR, Overground and Elizabeth line under one daily cap, but a black cab is paid separately by meter, in cash or card.

Is there a daily cap on how much I pay for tube and bus journeys?

Yes. TfL automatically caps the total fare per day and per week when you pay with Oyster or contactless, so you never need to work out the cheapest ticket yourself.

Are black cabs safe at night compared to the tube?

Licensed black cabs are a reasonable choice late at night when tube frequency drops, especially for solo travellers or anyone carrying luggage between a station and a hotel door.

Do black cabs take cards?

Most licensed black cabs now accept contactless and card payment as well as cash, though it is worth confirming before the journey starts if you have no cash as a backup.

Is every black cab wheelchair accessible?

Yes. Every licensed black cab is legally required to carry a wheelchair without the passenger transferring to a seat, which makes it the most reliable door-to-door option for step-free travel, ahead of many older tube stations.

Does the tube run all night in London?

No. Regular Underground service stops in the small hours, and Night Tube only runs on a handful of lines on Friday and Saturday nights. Night Buses, marked with an N before the route number, cover the rest of the network every night of the week.
