You can now use your contactless debit card, Apple Pay or Android Pay to pay for London transport services. If you don’t have these, you can also purchase an Oyster card or a traditional ticket in any underground station for use on Transport for London (TfL) buses, Underground and Overground train services. There is a fare cap of £9.70 per day. Fare prices can be found on the TfL website tfl.gov.uk.
Make sure you tap in and out using the same contactless card or Oyster card to avoid penalty charges.
There is an extensive bus network in London with a flat rate of £1.50 per journey. If you switch buses within an hour of taking the first, you will not be charged again. You can easily plan your bus travel using Google Maps or Citymapper.
Leave extra travel time at rush hour as the Underground gets extremely busy between 8 and 9am.
London also has a network of city bikes (the red Santander bikes), tfl.gov.uk will help you find your nearest docking station.
