The Competition and Markets Authority has opened investigations into Trainline, Virgin Atlantic, and Red Driving School for alleged drip pricing — the practice of advertising one price, then layering on mandatory fees late in the checkout process. The CMA's observed fees ranged from 50p to £2.79 per transaction. Small per-ticket, but the principle scales: drip pricing works precisely because each individual charge seems too trivial to abandon a purchase over. This is not a Burnham-era initiative. The CMA's consumer protection drive pre-dates the current prime minister and was enabled by the Digital Markets, Competition and Consumers Act of 2024, passed under the previous Tory government. That legislation gave the CMA direct enforcement powers — no more going to court under consumer protection laws. Eight cases were opened last November; driving schools AA and BSM plus StubHub UK have already been fined. The market heard the signal clearly. Trainline shares dropped 14% on the announcement — a disproportionate punishment for fees measured in pence, which tells you how much the market believes the ticketing platform's revenue model depends on pricing opacity. Trainline is the only publicly quoted company among the three targets, making it the visible example. Trainline's response was revealing in what it didn't say. The company stated it had "proactively engaged with the CMA over several months" and was "taking steps to enhance the presentation of certain fees." The obvious question: if you've been talking to the regulator for months, why didn't you just fix the display on day one? The fees apply to roughly 30% of journeys. Showing them upfront would cost nothing in engineering effort and almost nothing in conversion. There is a plausible technical defense. Trainline creates genuine value by navigating Britain's baroque fare structures — split tickets, obscure railcards, multi-leg optimizations. If the fee depends on which ticket type the algorithm finds, precise disclosure at the start of the booking flow may be structurally difficult. But this is exactly the kind of detail that months of CMA engagement should have resolved. The timing is brutal for Trainline. Great British Railways, the state rail body, is expected to launch its own fee-free ticketing app. A regulatory investigation for price opacity is the worst possible backdrop for arguing that your private-sector platform deserves to survive alongside a government alternative. The CMA can order refunds and fine up to 10% of turnover. The deeper pattern is encouraging. Direct enforcement powers mean regulators can move at the speed of the market rather than at the speed of litigation. Fining AA, BSM, and StubHub UK before even reaching Trainline creates a credible deterrent cascade. The question is whether this enforcement model gets applied consistently across sectors or remains a consumer-protection highlight reel.
