March has been another active month at Join the Claim.
From tracking developments in major group claims to publishing practical guides on everyday consumer rights, our focus remains the same: helping people understand what’s happening, what it means, and what their options might be.
Here’s a look at what we’ve been working on this month.
New claims added to the website
We added several potential new claims to jointheclaim.com, so UK consumers can quickly understand what’s happening and whether they might be due compensation.
This month, we highlighted:
CarGurus data breach
Online car marketplace CarGurus is the latest company to be targeted by the hacking group known as ShinyHunters.
Some reports suggest the dataset may contain more than 12 million email addresses. CarGurus is already facing several lawsuits in the United States following the cyberattack.
TfL data breach
Transport for London (TfL) suffered a major cyber-attack in 2024 that exposed a large database of customer information. Investigations have since revealed that the breach may have affected around 10 million people, making it one of the largest known data breaches involving a UK public body. Was your data exposed?
ManoMano data breach
ManoMano, the French DIY and home-improvement marketplace, has warned customers that their personal data may have been accessed in a cyberattack. A hacker has claimed responsibility online, alleging that approximately 37.8 million user accounts were affected, including in the UK. If you are a UK customer and your personal data was compromised, you may be entitled to compensation.
Apple iCloud subscription claim
A new £3 billion claim by Consumer group Which? alleges Apple restricted competition and overcharged up to 40 million UK Apple customers who obtained iCloud services. If approved, this claim is expected to proceed as an ‘opt-out’ collective action. That means, if you meet the criteria, you don’t need to take any action for the claim to be brought on your behalf.
Op-out claims explained – a new guide
Across the UK, global corporations are being challenged through collective actions worth billions of pounds.
These cases are part of a legal system designed to return money to consumers when large companies are accused of overcharging or abusing their market power. But despite the scale of these claims, most people have no idea they could be affected.
At Join the Claim, we have published a new consumer guide explaining what opt-out claims are.
Following major developments in the PlayStation competition case
This month we covered a major milestone in the long-running PlayStation competition claim, as the case against Sony Interactive Entertainment moved into the trial stage.
The proceedings are now being heard at the Competition Appeal Tribunal, where lawyers for the claimants argue that PlayStation’s digital marketplace may have restricted competition and led UK gamers to pay higher prices for digital games and in-game purchases. Sony strongly denies the allegations and says its platform rules are necessary to protect players and maintain security.
Because the case has been certified as an opt-out collective action, millions of UK PlayStation users who bought digital games or add-on content during the claim period could automatically fall within the group. As the trial progresses, we are continuing to track the case and explain what the legal arguments mean for players who may be affected.
Raising awareness of the digital ID debate
We also looked at the government’s decision to relaunch plans for a national digital identity system.
However, the announcement has already reignited wider debate around privacy, data security and public trust.
While supporters argue digital ID could make accessing services quicker and more convenient, critics have raised concerns about how large identity databases are protected and how voluntary systems can gradually become embedded across everyday services.
Useful explainers to educate and inform
Legal terms can be confusing, headlines don’t always tell the full story, and small details often make a big difference to what consumers can actually do.
That’s why we continue to publish practical explainers alongside our claim updates
These guides break down complex topics in clear, everyday language so people can better understand their options and make informed decisions.
This month, we looked at:
- Signed a “no win, no fee” claim and having second thoughts? Here’s what to know
- Is it “just” your name and email? Why so-called simple data breaches still matter
- Parents who had children between 1978 and 2010 could be owed thousands in state pension backpay
- Smart meter problems: the new 90-day rule that could mean £40 compensation
Breaking down the Amazon ruling
This month, Amazon failed in its latest attempt to stop two major UK competition claims worth up to £4 billion from moving forward.
The Court of Appeal refused Amazon permission to appeal earlier rulings that allowed the cases to proceed. That means both lawsuits – one brought on behalf of retailers and another on behalf of consumers – will now continue through the courts.
For millions of shoppers and thousands of UK businesses, this is a significant moment.
We broke down what the ruling meant and what will happen next.
Shining a spotlight on breaking data breaches
At Join the Claim, we keep a close eye on these developments and break them down in clear, practical terms. This month, we highlighted several significant data security incidents.
Companies House data breach: millions of UK businesses potentially exposed
A security flaw at Companies House may have exposed sensitive company and director information. The issue, linked to a technical error in its WebFiling system, has now been fixed. However, with investigations still ongoing, businesses are being urged to check their records and stay alert.
Massive breach exposes around 45 million French records
A huge database containing tens of millions of French citizens’ records has been discovered sitting openly on a cloud server. According to researchers, the archive appears to combine data from at least five separate breaches – including voter information, healthcare registries, financial profiles and vehicle data. In total, it is believed to contain around almost 45 million records.
Banking app glitch lets customers see other users’ transactions (Lloyds, Halifax, and Bank of Scotland)
Customers using mobile banking apps for Lloyds, Halifax, and Bank of Scotland reported a serious technical issue that appeared to display transactions belonging to other people.
Questions remain about how the error occurred and whether any personal financial information may have been exposed.
