What is the cheapest way to get around London? With the Tube, buses, Overground, trams, river boats, cable cars and Santander Cycles all on offer, London’s transport menu is bewildering — and the price differences are enormous. The same journey can cost £1.75 or £7 depending on how you pay and what you ride. Here’s how to navigate it like a local and pay the minimum.

The golden rules

1. Never pay cash. Cash fares are the most expensive option on everything. Always use contactless or Oyster.
2. Buses (and trams) are the cheapest motorised transport: a flat £1.75 per journey, with the Hopper fare giving unlimited bus/tram journeys within an hour for that £1.75.
3. Daily capping saves you: contactless and Oyster automatically cap what you pay per day (and per week, Monday–Sunday, on contactless) — you’ll never pay more than the cap no matter how much you travel.
4. Avoid Zone 1 if you can — journeys avoiding central London are cheaper, and buses don’t have zones at all.

What is the cheapest way to get around London? By mode

Bus — the budget champion (£1.75)

Flat fare, no zones, Hopper fare for connections. Slower than the Tube, but you see the city — and for many central journeys the time difference is minimal. If you’re not in a hurry, the bus wins on price every time. (Note: buses are cashless — contactless/Oyster only.)

Tube/DLR/Overground — fast, zoned

Contactless/Oyster off-peak: Zone 1–2 from around £2.80–£3.40 depending on current fares; peak (6:30–9:30am, 4–7pm weekdays) costs more. Daily cap for Zones 1–2 is roughly £8–£9. Check current fares on the TfL fares page — they change most years. Key savings: travel off-peak, stay within fewer zones, and let weekly capping (contactless only) handle heavy-travel weeks.

Walking — free and often fastest

Central London is compact: Leicester Square to Covent Garden is a 4-minute walk that the Tube turns into a 15-minute faff. For Zone 1 hops, walking is frequently as fast as the Underground once you count stairs, waits and changes. Plus it’s, you know, London — look up occasionally.

Santander Cycles — £1.65 per 30 minutes

Brilliant for short hops: the hire scheme costs £1.65 per 30-minute ride (or £20/month for unlimited 60-minute rides). Docking stations are everywhere in central London. Faster than the bus for many journeys, cheaper than the Tube, and you get some exercise. E-bikes cost more — stick to the classic red bikes for value.

River bus (Uber Boat) — the scenic splurge

Not the cheapest, but worth knowing: the Thames Clippers are a legitimate (if pricier) transport option, and the views are unbeatable. Use contactless for a discount on the standard fare.

Oyster vs contactless

For most visitors, contactless (bank card or phone) is simplest — same fares as Oyster, no card to buy, plus Monday-to-Sunday weekly capping. Oyster (see how to use an Oyster card) makes sense if you don’t have contactless, want a physical card for kids, or have a railcard discount to link. Never buy a Travelcard unless you’ve done the maths — capping usually beats it.

Tourist traps to avoid

• Black cabs for routine journeys — iconic, comfortable, and roughly 5x the Tube price. Save them for late nights or treats.
• The Heathrow Express (£25+) vs the Elizabeth line or Piccadilly line (£5–£13) — the time saving rarely justifies triple the price.
• Hop-on-hop-off buses as transport — they’re tours, priced accordingly. Use them for sightseeing, not getting around.
• Uber at surge — check the Tube first; surge pricing in central London is brutal.

Getting to and from the airports (cheaply)

• Heathrow: Elizabeth line (~£13 peak/£5–£10 off-peak with contactless — check current fares) or Piccadilly line (cheapest, ~£5–£6, slower). The Heathrow Express (£25+) is rarely worth it. Heathrow’s transport pages list all options.
• Gatwick: Southern/Thameslink trains to Victoria or London Bridge (~£10–£20) beat the Gatwick Express (£20+) on value — often barely slower.
• Stansted: Stansted Express (£20+) vs National Express coach (£10–£15, slower). Book the coach ahead for the best prices.
• Luton: the DART shuttle + Thameslink; or the coach. Allow generous time — Luton’s transport links are the faffiest.
• London City: DLR straight in — the easiest airport transfer in London.

The pattern: the “Express” branded services are for people expensing it. Everyone else takes the regular trains.

London transport FAQs

Can two people share one contactless card? No — each person needs their own card or device. One card, one traveller. (Children under 11 travel free with a fare-paying adult on most TfL services.)

What are the peak hours? Weekdays 6:30–9:30am and 4–7pm. Off-peak fares are meaningfully cheaper on the Tube/Overground. If your schedule’s flexible, travelling at 9:45am instead of 9:15am saves money and sanity.

Is the Night Tube running? On select lines (Central, Jubilee, Northern, Piccadilly, Victoria) on Friday and Saturday nights. Otherwise, night buses cover the city — the bus network runs all night and the £1.75 fare (with Hopper) makes it the budget late-night option.

How do I get a refund for an overcharge? Through your TfL online account — register your contactless card or Oyster, and claim for incomplete journeys or errors. They’re generally fair about genuine mistakes. Check your journey history monthly; overcharges are more common than you’d think.

The weekly cap trick for longer stays

Staying a week or more? Contactless weekly capping (Monday to Sunday) is your best friend — it automatically limits what you pay across the week, equivalent to a weekly Travelcard but without buying one in advance. The strategy: use the same contactless card or device for every journey all week, and let the cap do its work. For most visitors doing 3–4 Tube journeys a day in Zones 1–2, you’ll hit the weekly cap by Thursday or Friday — then the weekend’s travel is effectively free. Combine with buses for short hops (£1.75 flat, Hopper fare) and walking for central journeys, and a week’s unlimited-feeling travel costs less than most people expect. The common mistake: mixing payment methods (phone one day, card the next) — this breaks the capping and you pay full whack. Pick one payment method on Monday and marry it for the week. Check your TfL online account to see the capping working — it’s weirdly satisfying watching Friday’s journeys cost £0.00.

The practical takeaway

The cheapest way to get around London: walk the short hops, take the bus (£1.75 flat, Hopper fare) for medium ones, use the Tube off-peak with contactless for speed (daily/weekly capping protects you), and try Santander Cycles for fun cheap rides. Never pay cash, avoid Zone 1 premiums where easy, and skip the Heathrow Express. For the card itself, read how to use an Oyster card in London — and plan your days with how many days you need.
