London is genuinely expensive to sleep in and unusually cheap to spend a day in, because the thing that costs most in other capitals — the major museums — is free here.
The free list
All with free general admission, all world-class:
The British Museum — the Rosetta Stone, the Parthenon sculptures, the Egyptian galleries.
The National Gallery on Trafalgar Square, open late on Fridays.
The Natural History Museum and Science Museum in South Kensington, 300 metres apart.
The V&A, next to them, and the better choice for most adults.
Tate Modern and Tate Britain.
Special exhibitions are ticketed; the permanent collections are not. The British Museum and Natural History Museum benefit from a free timed slot booked online.
Also free: the Sky Garden with advance booking, Greenwich Park and the Royal Observatory grounds, Borough Market to walk through, and the changing of the guard.
The contactless cap
Tap a contactless bank card or phone. It is the cheapest fare available and caps automatically.
| Cap | Approx |
|---|---|
| Daily, zones 1–2 | £8.90 |
| Weekly, zones 1–2 | £44.70 |
| Daily, bus only | £5.25 |
There is no reason for a visitor to buy an Oyster card or a Travelcard.
Two rules that cost money if broken: tap out on rail, or you are charged a maximum fare, and use the same card all week, since alternating between a phone and a physical card splits the total and neither caps.
Buses cap separately and lower, which makes them the cheap option for a day of short hops. The top deck of routes 11, 15 or 24 is a sightseeing tour at bus fare.
Where to stay
| Area | Zone | Character |
|---|---|---|
| Whitechapel / Bethnal Green | 2 | East, well connected, cheap |
| Peckham / Camberwell | 2 | South, good food, cheap |
| Brixton | 2 | Market, nightlife, Victoria line |
| Stratford | 2/3 | Modern, excellent transport |
| Bloomsbury / South Bank | 1 | Central, walkable, pricier |
Zone 2 with a good Tube line is the value answer — fifteen to twenty minutes from the centre and meaningfully cheaper.
Avoid anywhere marketed as "near London" in zones 5 and 6. The nightly saving is erased by the commute and by fares outside the zone 1–2 cap.
Eating for less
Markets. Borough for quality, Maltby Street and Broadway Market for lower prices, Brixton Village for genuinely cheap and good.
Pub lunch deals and Sunday roasts, which are better value than dinner.
Chain lunch meal deals at £4–6, which is what most Londoners actually eat at midday.
Ethnic food corridors — Whitechapel for Bangladeshi, Green Lanes for Turkish, Southall for Punjabi — where a full meal costs £8–14.
What genuinely needs booking
The Tower of London, Westminster Abbey, the London Eye, and theatre. That is the list.
For theatre, the official TKTS booth in Leicester Square sells genuine same-day discounts; the street sellers nearby are not the same thing.
The London Pass only pays off at three or more paid attractions a day, every day. Since the flagship museums are free, it mostly covers things many visitors would skip.
