CMA Opens Consumer Protection Investigation Into Trainline Over Mandatory Fee Presentation in Ticket Sales
The Competition and Markets Authority has launched a consumer protection enforcement case against Trainline, investigating suspected infringements of consumer law relating to how mandatory fees for train and coach tickets are presented to customers in the UK. The CMA's concern is that fees which must be paid are not being displayed as part of the total price shown to consumers at the point of sale. The investigation is at an early stage and no findings of infringement have been made.
Why this matters
The CMA's move against Trainline signals that mandatory fee transparency is now an active enforcement priority, not merely a compliance expectation. The timing follows the entry into force of consumer protection provisions under the Digital Markets, Competition and Consumers Act 2024, which gives the CMA stronger direct enforcement powers without requiring court action. Online ticketing platforms across travel and entertainment sectors face heightened scrutiny of how they present unavoidable charges. A finding against Trainline could set a precedent that cascades across the sector.
On the Ground
Consumer protection and regulatory practices will advise platform clients to audit fee-display flows immediately against the CMA's published enforcement priorities. Competition counsel will monitor the investigation's scope and timelines to assess litigation risk. A trainee would be tasked with mapping the client's checkout journey against CMA guidance, preparing a compliance memo, and tracking the case page on gov.uk for procedural updates.
