TfL/Sadiq Khan the Mayor of London have today announced that with effect from January 2024 (precise date pending) TfL will cease to retail or accept 1 day Travelcards. This is because they feel they are not getting a sufficient revenue share from them.

7-day, monthly, and longer Travelcards will remain offered.
