• Apple App Store lawsuit UK is a £1.5bn class action over allegedly unfair 30% commissions impacting 20m users.
• First tech giant class action trial in UK courts, with Google case in 2025.

Twenty million British iPhone and iPad users are taking Apple to court, claiming £1.5 billion in damages over what they describe as excessive App Store commissions. The lawsuit, filed at London’s Competition Appeal Tribunal, challenges Apple’s mandatory 30% commission on app developers – a fee structure that consumers argue ultimately inflates costs.

The case marks a significant milestone as the first mass lawsuit against a tech giant to proceed to trial under Britain’s emerging class action-style regime. At its core, the lawsuit challenges App Store practices in the UK, especially on the controversial 30% commission rate that Apple charges app developers, a practice that the plaintiffs argue ultimately impacts consumer costs.

British academic Rachael Kent leads the action, and whose legal team contends that Apple has exploited its market position to generate “exorbitant profits” by eliminating all competition in app distribution and in-app purchases. The plaintiffs’ position, articulated by lawyer Mark Hoskins in court filings, emphasises Apple’s complete market control, stating explicitly that “Apple is not just dominant […] it holds a 100% monopoly position.”

Apple’s defence presents a markedly different perspective, asserting that the lawsuit overlooks important benefits provided by its integrated iOS operating system approach. The company’s legal team, led by Marie Demetriou, maintains that the commission structure reflects “the enormous benefits conferred through Apple’s innovation by the iOS ecosystem as a whole.”

Apple’s court filings state that 85% of developers do not pay any commission, challenging the plaintiffs’ characterisation of their fee structure. The defence says the case fails to acknowledge Apple’s intellectual property rights. Demetriou explicitly addresses the plaintiffs’ position regarding developer access to Apple’s technology, describing it as an “expropriation of property rights masquerading as competition.”

The company maintains that its integrated approach prioritises important consumer interests, particularly security and privacy. The legal challenge in the UK emerges amid increasing regulatory scrutiny of Apple’s App Store practices globally, particularly in the United States and Europe.

The timing is significant as it coincides with similar actions against tech giants in Britain. Google faces a comparable $1.1 billion lawsuit scheduled for later in 2025, focusing on Play Store commission charges. Meta and Amazon are also set to contest high-value mass lawsuits in British courts.

The Apple App Store lawsuit UK represents more than just a challenge to one company’s practices; it serves as a test case for Britain’s evolving approach to consumer protection and the class-action legal model. The outcome could influence how similar cases are handled in the UK and internationally, particularly as governments worldwide grapple with regulating large technology platforms.

The trial, set to span seven weeks, will feature testimony from key Apple executives, including Chief Financial Officer Kevan Parekh, who is expected to take the stand later this week. Their testimony could provide important insights into Apple’s App Store operations and the rationale behind the company’s commission structure.

The lawsuit’s focus on commission structures and market dominance touches on issues that extend beyond Apple to the broader digital marketplace ecosystem. The implications of this case could be far-reaching, potentially influencing how digital marketplaces operate in the UK and potentially inspiring similar legal challenges at home and abroad.

As the trial proceeds, it will be closely watched by industry observers, legal experts, and other tech companies, all of whom recognise its potential to reshape the landscape of digital marketplace operations.
