Tfl is Transport for London’s official website for public transport in the capital. It covers travel on the Tube, buses, London Overground, DLR, Elizabeth line, trams and river services, and it also provides information on cycling, driving and congestion charging.

On tfl.gov.uk, savings tend to come from fare caps and discounted travel products rather than sales. You can compare pay as you go fares with Travelcards, check daily and weekly capping, and find eligibility details for concessions such as child, student, apprentice, 18+ Student Oyster, Jobcentre Plus and older person or disabled travel schemes.

The site is a public service portal rather than a retail shop, and it is where you can manage Oyster and contactless accounts, apply for certain travel cards and pay road user charges. It also publishes live service updates, planned works and journey planning tools.
