The Competition and Markets Authority (CMA) is examining Trainline.com Limited (Trainline) over whether required charges appear in the first price shown to customers buying train and coach tickets in the U.K.
The CMA opened the case on Aug. 18, 2026. It is focused on whether Trainline includes mandatory ticket fees in the total visible at the start of a purchase. The regulator classifies the matter as a consumer-enforcement case in the transport sector.
The CMA says it will engage with Trainline and gather evidence to assess whether the company infringed consumer-protection law. The investigation remains open, and the agency has made no finding. It says the opening of the inquiry should not be treated as proof that Trainline broke the law.
The CMA’s timetable runs the initial evidence-gathering phase from August 2026 through January 2027, with the next case update scheduled for January 2027. The case page was first published Aug. 19, 2026, a day after the investigation opened. Its Nov. 9 update changed the project director and did not announce a new case finding.
