London is one of the world’s most accessible and fascinating cities, but its sheer size, unique etiquette, and high costs can easily trip up first-time visitors. From costly transport errors to social gaffes, a few simple missteps can drain your energy and your wallet.
Here is your essential guide to the most common mistakes tourists make in London and the smart ways to avoid them.
1. Underestimating Walking Distances (The “It Looks Close on the Map” Mistake)
On the Tube map, the journey between Covent Garden and Leicester Square is a single stop. In reality, it’s a 20-minute walk above ground. Many new visitors underestimate the sheer size of Zone 1.
-
The Mistake: Trying to walk two or three Tube stops that are misleadingly close on the map, exhausting yourself before noon.
-
The Fix: Use Google Maps or CityMapper for walking time, not the Tube map. If a walk is over 25 minutes, save your energy—take the bus or Tube. Alternatively, always choose comfortable, broken-in shoes; you will be walking miles daily.
-
Bonus Tip: The distance between the Leicester Square and Covent Garden Tube stops is famously short; always walk this one!
2. Breaking Tube Etiquette (The Cardinal Sin)
Londoners have evolved a highly specific set of unspoken rules for using the Underground. Breaking them earns silent, yet profound, disdain.
-
The Mistake: Blocking the flow of people and causing delays. The four cardinal sins are: standing on the left of the escalator, stopping abruptly after exiting a train, making prolonged eye contact, and attempting to board before letting passengers off.
-
The Fix:
-
Stand on the Right, Walk on the Left: This is the most crucial rule on escalators. The left is the passing lane.
-
Keep Moving: When getting off a train or reaching the top of an escalator, walk forward to the side of the platform to check your map.
-
Silence is Golden: Avoid unnecessary conversation or loud phone calls on the Tube.
-
Take Off Your Backpack: If the carriage is busy, take your backpack off and hold it by your side (or between your legs) to create space.
-
3. Buying Paper Tickets or Using Cash (The Costly Transport Error)
London’s transit network is based on a smart digital system that punishes cash users.
-
The Mistake: Buying expensive, single-use paper tickets or trying to pay cash on a bus (which is impossible, as buses are cashless).
-
The Fix: Use Contactless Payment. Tap the same credit/debit card or phone pay device (Apple Pay/Google Pay) for every journey. TfL automatically “caps” your spending (daily and weekly) so you always pay the cheapest possible fare.
-
Bonus Tip: Always remember to tap in AND tap out when using the Tube, Overground, and Rail networks. If you forget to tap out, you’ll be charged the maximum zone fare.
4. Taking a Taxi from Heathrow (The £100+ Mistake)
Taxis are a great convenience, but not from the airport.
-
The Mistake: Taking a Black Cab directly from Heathrow to a central London hotel, resulting in a fare of £70 to £100+ due to traffic and distance.
-
The Fix: Use the Elizabeth Line (30-40 mins, approx. £13) or the Piccadilly Tube Line (60 mins, approx. £5.60) to get into Central London. Once there (e.g., at Paddington or King’s Cross), take a much cheaper, shorter taxi ride to your hotel.
5. Expecting Table Service in Pubs (The Awkward Wait)
Pubs operate on a different service model than restaurants.
-
The Mistake: Sitting down at a pub table and waiting for a server to come and take your drink order.
-
The Fix: Order and pay at the bar. Pubs are counter-service establishments for drinks. If you are ordering food, you often order at the bar, pay, and are given a table number for the food to be delivered.
-
Bonus Tip: Check the bill at restaurants. A Service Charge (typically 10-15%) is often already included. If it is, tipping extra is not necessary.
6. Not Booking Major Attractions In Advance
London’s most famous paid attractions (and some free ones) are in high demand globally.
-
The Mistake: Showing up at the Tower of London or the London Eye without a ticket, only to face massive queues or find the day is sold out.
-
The Fix: Book Online and Book Early. This is vital for the Tower of London, the London Eye, the Warner Bros. Studio Tour (Harry Potter), and the free Sky Garden (which requires a free timed ticket released weeks in advance).
7. Looking the Wrong Way When Crossing the Street
Traffic flows on the left, which is an immediate safety hazard for those used to driving on the right.
-
The Mistake: Looking left, then right, then stepping out and realizing you looked the wrong way for the immediate lane of traffic.
-
The Fix: Look for the block letters on the pavement! At major crossings, London has the words “LOOK LEFT” or “LOOK RIGHT” painted onto the road. Trust the painted instruction and always wait for the Green Man pedestrian signal.
