Apple faces £2 billion UK class action over App Tracking Transparency

A £2 billion claim against Apple

Apple faces a collective action worth around £2 billion in the United Kingdom, filed on September 3, 2026 at the Competition Appeal Tribunal (CAT). The claim concerns App Tracking Transparency (ATT), the framework that requires apps to ask permission before tracking a user across other apps and websites.

Still at the certification stage

According to The Mac Observer, Apple had published no response to the ATT claim as of September 13, 2026, and had not said whether it would contest certification. The next concrete step is certification of the claimant group, which the tribunal has not yet scheduled.

Background: ATT since 2021

Introduced with iOS 14.5 in April 2021, ATT requires developers to obtain explicit consent before using the advertising identifier. It has been the subject of several legal battles in Europe ever since.
