London in 2 Days on a Budget (With Daily Costs)
Two days holds the free Westminster walk and Buckingham Palace on day one, then the free British Museum and the one paid splurge of this whole trip, the Tower of London, on day two. It’s tight but genuinely budget-able: roughly GBP 85-105 total across two days, food and transit included. Need more room? See the 3-day or 7-day version of this same route.

Day 1: Westminster, Buckingham Palace and the South Bank, free
Land, get to the hotel, and spend day one on foot without booking a single ticket. Walk Westminster while the queues haven’t formed yet: Big Ben’s exterior and the Houses of Parliament, then Westminster Abbey’s west front (it’s closed to tourists on Sundays, worship only, so check the day of the week if you want to go inside later in the trip). Cut through St James’s Park toward Buckingham Palace for the Changing of the Guard, free to watch, provisionally Monday, Wednesday and Friday around 11:00 (the schedule is weather-cancellable, so check the week you’re there).
Is the Changing of the Guard actually worth getting up early for?
Yes, and it costs nothing. Arrive by 10:30 to get a sightline along the railings; the ceremony itself runs 30-45 minutes and needs no ticket, no booking and no queue beyond finding a spot to stand. It’s the single best free spectacle on this list, and skipping it to save time is the one mistake budget itineraries make.
Cross Westminster Bridge (ignore anyone running the three-cup game near the London Eye, it’s a rigged street hustle, keep walking) and pick up the South Bank walk toward Tate Modern and Borough Market, roughly Monday-Friday 10:00-17:00 and Saturday 9:00-17:00. Grab a Boots or Pret meal deal for lunch, GBP 3.60-7, and if the budget stretches to an evening splurge, check Thames river cruise prices on Viator rather than paying for the London Eye. Tap in with contactless or Oyster all day; the Zone 1-2 cap is GBP 8.90, and today should run roughly GBP 35-45 all in, food and transit, zero paid sights.
Day 2: The free British Museum and the one paid splurge
Book a free timed slot at the British Museum before you leave home if it’s a weekend, a school holiday, or anytime through summer, since the Bayeux Tapestry’s first loan outside France opens there in autumn 2026 and will only tighten availability further. The Rosetta Stone and the Parthenon sculptures alone can fill a morning, and it costs nothing.
Is the Tower of London worth GBP 37 on a tight budget?
Yes, once. It’s the one paid sight in this itinerary worth the money: the Crown Jewels and the White Tower cover nearly a thousand years of continuous royal history that no free museum duplicates. Book online through hrp.org.uk or check skip-the-line Tower of London tickets on GetYourGuide rather than queuing at the gate.
Walk across Tower Bridge afterward, free, and finish with dinner grazing through Borough Market rather than trekking back to the West End. Today runs roughly GBP 50-60 with the Tower ticket included, the most expensive day on this itinerary and the only one that needs to be.
Before you go
A contactless bank card or phone charges the same fare as an Oyster card and shares the same daily cap, GBP 8.90 for Zone 1-2, so most visitors don’t need a physical Oyster at all. Restaurant service charges of 12.5% are often added automatically; if it’s already on the bill, no further tip is expected. Two days is enough for one free museum and one paid sight, not enough to add Greenwich or South Kensington without rushing, extend to our 4-day budget itinerary if this is your only London trip for a while.
