Britain's competition regulator isn't messing around anymore. On August 18, 2026, the Competition and Markets Authority (CMA) launched three new investigations targeting some of the country's most recognizable consumer brands over suspected drip pricing violations. Trainline, Virgin Atlantic, and Red Driving School now face formal probes into how they display mandatory charges to customers, and the stakes couldn't be higher. The investigations focus on a practice regulators hate with a passion: showing customers a low headline price, then dripping in unavoidable fees as they progress through checkout. For Trainline, the CMA is scrutinizing booking fees ranging from 50 pence to £2.79 for train tickets, plus a £1.50 charge for coach journeys that allegedly weren't displayed upfront on the app and website. Virgin Atlantic is under the microscope for how it presents mandatory resort fees and local taxes on package holidays. Red Driving School faces questions about a mandatory booking fee plus a so-called digital fee, typically £7 per booking, that may not have been properly disclosed when customers tried to book driving lessons. These aren't the CMA's first rodeo. The regulator has been on an absolute tear since gaining new direct enforcement powers under the Digital Markets, Competition and Consumers Act 2024 (DMCCA), which took effect in April 2025. The law explicitly bans drip pricing and gives the CMA the power to issue fines of up to 10% of global annual turnover without needing to go through the courts first. That's a nuclear option compared to the old regime, where the CMA had to persuade companies to change voluntarily or drag them through lengthy court battles. The results speak for themselves. In April 2026, the CMA imposed its first fine under the new powers: a £4.2 million penalty against AA Driving School and BSM Driving School (both owned by Automobile Association Developments Limited) for hiding a mandatory £3 booking fee from more than 80,000 learner drivers. The company also had to refund over £760,000 to affected customers. That fine was actually reduced by 40% from an original £7 million because the AA admitted liability early and agreed not to appeal. In June 2026, the CMA fined StubHub UK nearly £900,000 and ordered more than £590,000 in refunds for similar violations involving event ticket sales. The message is clear: cooperate early or pay more. All three companies under investigation have issued carefully worded statements emphasizing their commitment to transparency. A Trainline spokesman said the company has been proactively engaging with the CMA for several months and is taking steps to enhance how certain fees are presented. Virgin Atlantic Holidays said it takes customer responsibility seriously and wants to ensure people can make informed purchasing decisions. The companies are playing nice because they've seen what happens when you don't. At this stage, no findings of wrongdoing have been made, but the CMA has already put these firms on notice before opening formal investigations, so the regulator clearly thinks it has a case. The CMA's broader campaign against dodgy pricing practices is unprecedented in scope. Since launching its consumer protection drive in November 2025, the watchdog has investigated eight businesses for online pricing violations, sent enforcement letters to 100 companies, and reviewed more than 400 businesses for price transparency compliance. Executive director for consumer protection Emma Cochrane summed up the regulator's philosophy: clear pricing helps people compare offers confidently and choose what works best for them, while unexpected mandatory charges make that much harder. The current investigations into Trainline, Virgin Atlantic, and Red Driving School will now move into an evidence-gathering phase, with the CMA engaging directly with each company to determine whether consumer protection law was actually broken.
