Apple Brings In HSF Kramer to Fight the £3 Billion iCloud Class Action Here Is What UK iPhone Users Need to Watch

Apple has instructed Herbert Smith Freehills Kramer (HSF Kramer) to defend it in a class action brought before the UK Competition Appeal Tribunal — the first time it has done so for an opt-out collective action at that court. The case in question is Consumers’ Association (Which?) v Apple Inc and Others, Case No. 1689/7/7/24, and it directly affects tens of millions of people who use iCloud on an iPhone or iPad in the UK.

If you have ever paid for iCloud storage in the UK, this case may already include you — and you do not need to do anything right now to stay in it.

What Is the Which? v Apple iCloud Case About?

Consumer group Which? brought a damages claim on behalf of around 38.5 million UK iPhone and iPad users, alleging that Apple abused its dominant position in iOS by unfairly favouring its own iCloud service, restricting consumers’ ability to use rival cloud storage providers while steering them toward iCloud.

The claim rests on Section 18 of the Competition Act 1998 and (for the period before December 31, 2020) Article 102 of the Treaty on the Functioning of the European Union — the laws that prohibit dominant companies from abusing their market power. Which? argues that iOS has a monopoly over Apple’s operating system and that it is incumbent on Apple not to use that dominance to gain an unfair advantage in related markets, like the cloud storage market.

Which? previously indicated that the claim could be worth up to £3 billion in total damages, with an average payout per user of around £70. Beyond financial compensation, Which? is also asking the CAT to order Apple to structurally open up iOS so that users can freely choose any cloud storage provider — not just pay a damages cheque and carry on as before.

Why Apple Switching to HSF Kramer Matters for This Case

Until now, Apple used Gibson Dunn & Crutcher to defend its major UK opt-out class actions. It was Gibson Dunn that represented Apple in the landmark App Store collective action brought by Dr Rachael Kent — a case Hausfeld won on behalf of approximately 36 million iPhone and iPad users, resulting in a ruling that Apple could be liable for around £1.5 billion in damages.

That loss appears to have prompted a change of strategy. This is the first time Apple has instructed HSF Kramer for an opt-out collective action in the Competition Appeal Tribunal.

HSF Kramer is not a new name in this space — it is deeply embedded in it. The firm successfully represented Apple and Amazon in January 2025, when the CAT refused to certify a separate opt-out competition class action on the basis that the proposed class representative was not suitable — the first time the tribunal had ever refused certification on those grounds. That experience defending against CAT certification proceedings gives HSF Kramer direct knowledge of how these cases are built and where they can be challenged.

As of 2024, HSF Kramer had the highest litigation revenue in the UK of any law firm. Bringing in that firepower signals Apple is treating the Which? case as a top-tier threat.

Where the Which? v Apple Case Stands Right Now

Which? applied for a Collective Proceedings Order (CPO), a type of class action, in 2024, on behalf of UK iOS users who allegedly paid more for iCloud storage because of Apple’s behaviour. Apple argued that the claims were unsuitable as a basis for a CPO, but the CAT rejected those arguments and allowed the claim to proceed.

The CPO application hearing took place in November 2025. The Tribunal issued its judgment on the CPO application on 2 April 2026. A separate hearing on Apple’s strike-out application has also taken place, with the judgment pending. A further hearing is listed for 3 June 2026.

This means the case is now certified and active. Apple is fighting on two fronts simultaneously — contesting the CPO grant on appeal and pushing a strike-out application. HSF Kramer steps in at precisely this high-pressure stage.

No settlement exists. No claim form is open. Most UK iPhone and iPad users who used iCloud from 1 October 2015 onward are automatically included in the class unless they actively opt out.

This case follows a pattern of mounting legal pressure on Apple in the UK, including the App Store collective action that resulted in a £1.5 billion ruling against Apple in October 2025.

Are You Part of This Class Action?

You may be part of this class if:

• You are a UK resident who used iCloud on an iPhone or iPad at any point from 1 October 2015 onward
• You used paid iCloud+ storage — these are the most directly affected class members
• You used free iCloud storage only — you may still qualify for injunctive relief even if your financial claim is lower
• You no longer use Apple devices but did so during the qualifying period — former subscribers are still included

You are likely NOT included if:

• Your only Apple devices were a Mac, Apple Watch, or Apple TV — the class covers iPhone and iPad iOS users specifically
• You are not and were not a UK-based user during the relevant period — non-UK users must actively opt in rather than being automatically included

Because this is an opt-out collective action, most eligible UK consumers do not need to do anything to remain in the class. To register for updates or check your eligibility, visit cloudclaim.co.uk.

Frequently Asked Questions

Is there a class action lawsuit against Apple over iCloud in the UK? 

Yes. The Consumers’ Association (Which?) is pursuing a £3 billion collective action at the Competition Appeal Tribunal on behalf of approximately 38.5 million UK iPhone and iPad users. The CAT granted a Collective Proceedings Order on 2 April 2026, certifying it as a proper class action.

Do I need to do anything right now to be included?

 No. UK residents who used iCloud on an iPhone or iPad from 1 October 2015 onward are automatically included unless they opt out. You do not need to file a claim form or register at this stage.

Why has Apple switched to HSF Kramer? 

Apple previously used Gibson Dunn to defend UK opt-out class actions, including the App Store case which Apple lost in October 2025. This is the first time Apple has instructed HSF Kramer for a CAT opt-out collective action — a firm with direct experience in CAT certification proceedings.

When could UK consumers receive compensation? 

TBD — no trial date has been set. Apple is likely to appeal the CPO grant. Any compensation is realistically several years away, pending appeal outcomes, trial scheduling, and a liability finding against Apple.

Will HSF Kramer’s involvement change the outcome for consumers? 

No law firm guarantees an outcome. However, HSF Kramer’s experience defending at CAT certification stage means Apple now has defence counsel with specific expertise in how these cases are structured and challenged. Which? and its litigation funder Litigation Capital Management remain committed to seeing the case through.

Can I file my own individual lawsuit against Apple instead?

 You can consult a consumer rights lawyer about individual options, but for most UK users the collective action is the practical route. Individual competition damages claims are complex and expensive — that is precisely why Which? brought this as a group action.

How much could I receive if Which? 

Estimates an average of around £70 per eligible user, though the actual amount depends on the total number of valid claims, Apple’s conduct period, and the tribunal’s final damages calculation. No compensation will be paid unless Apple is found liable at trial.
