Case opening

18 August 2026: The CMA has opened an investigation into compliance with consumer protection law by Trainline.com Limited (‘Trainline’).

The CMA is investigating Trainline over its presentation of mandatory fees, specifically whether these fees are included in the total price the consumer sees at the beginning of the process for purchasing train and coach tickets.

The CMA will now engage with Trainline and gather evidence to consider whether the CMA thinks Trainline has infringed consumer protection law.

At this initial stage, it should not be assumed that Trainline has infringed consumer protection law and no finding has been made.
