Group litigation is having a moment, with more and more people banding together to take on big organisations.
Whether seeking justice for data breaches or fighting misleading financial practices, group litigation demands wrongdoers take accountability and change their ways. But what’s driving this surge? And why are so many seeing the value in standing together?
We explore what’s behind the growth of group litigation, how it’s making justice more accessible, what makes it work, and the role technology is playing in helping people find and join claims faster than ever before.
Why group litigation is growing in popularity
Group litigation is no longer niche. It’s now one of the most powerful ways for consumers to challenge wrongdoing and level the playing field with big business.
Here’s why it’s growing fast:
Justice has become increasingly accessible
Several factors have made group litigation a more accessible path to justice, empowering people to stand up against large organisations.
Shared legal costs: Taking on a major company alone can be financially impossible. In group litigation, claimants share costs, reducing the financial burden for everyone involved.
Access to top-tier solicitors: Pooling resources attracts experienced law firms with the skills and funding to take on complex, high-value cases.
A more equal fight: With expert legal teams behind them, consumers can face corporate defendants on much fairer terms.
Digital access: Online platforms now make it simple to check eligibility, get updates, and join collective claims — all without needing to pick up the phone or visit a solicitor’s office.
No-win, no-fee has opened doors
No-win, no-fee arrangements have been a game-changer. They mean people can join claims without paying upfront, and pay nothing if the claim isn’t successful. For many, this removes the biggest barrier to justice: financial risk.
No-win, no-fee means you won’t pay your solicitor’s legal fees if your claim is unsuccessful. However, if you cancel after the cooling-off period or breach your agreement, some fees may apply. If your claim succeeds, the law firm will either deduct its pre-agreed fee from your compensation or recover costs from the defendant. All terms are explained clearly before you decide to join.

The UK legal system is catching up
While the US has long embraced class actions, the UK has been slower to adapt. That’s changing. Courts are now more open to large-scale collective claims, making it simpler for people to pursue justice together instead of filing individually.
People want accountability
Public trust has been shaken by major scandals — from the Post Office Horizon case to the M&S data breach. These events have fuelled public appetite for justice and shown that collective pressure works. When victims unite, their stories are harder to ignore.
Real-world examples of collective power
Group litigation is delivering real change and real results.
Diesel emissions claims
After it was discovered that several car brands had installed software to manipulate emissions readings, making vehicles appear more environmentally friendly than they actually were, car owners came together to sue the offending automobile manufacturers. Some ‘dieselgate’ claims are still ongoing.
This high-profile case not only empowered individual car owners but also shed light on the need for stricter environmental and consumer protection regulations.
British Airways data breach
When British Airways suffered a 2018 cyber-attack affecting 400,000 customers, victims joined a group claim over the loss of personal and financial data. The airline later agreed to settle — a clear signal that companies must take data protection seriously.
The Horizon Post Office scandal
Between 2000 and 2014, hundreds of Post Office employees were wrongfully accused of theft, fraud, and false accounting due to errors in Fujitsu’s Horizon IT system. A group litigation claim led to a £58 million settlement, further compensation payouts, and the quashing of criminal convictions for affected postmasters. A BBC programme amplified public awareness of the scandal, helping to cement its place in the national conversation.
PPI mis-selling claims
According to MoneySavingExpert, Martin Lewis, “PPI mis-selling is the UK’s single biggest financial scandal in living memory.” Widely mis-sold to customers who were either ineligible or unlikely to benefit from it, with banks and lenders failing to disclose the terms and limitations of the product, PPI was often added to loans and credit agreements without explicit consent. By 2019, compensation payouts for PPI mis-selling reached over £38 billion.
Technology is changing everything
The surge in group litigation popularity is closely tied to the evolution of digital platforms and social media, which have transformed the way people learn about and join collective claims.
Online hubs bring people together
Websites like Join the Claim give consumers a central place to learn about current cases, check eligibility, and connect with the law firms running them. This transparency helps remove confusion, builds trust, and gives people a clear path to act.
Social media spreads awareness
When high-profile cases are discussed on platforms like X, Facebook, and TikTok, they reach people who may have been affected but were unaware of the legal action. Social media also helps to unite people who may otherwise feel isolated or powerless against large corporations by providing a space for discussions and shared experiences. This collective momentum makes it easier for law firms to organise collective claims, further driving the popularity of group litigation.

Smarter systems for law firms
Behind the scenes, legal technology helps firms manage thousands of claimants efficiently — ensuring updates, data, and documents are handled securely. These tools make large-scale claims smoother for everyone involved and encourage more firms to take them on.
Ready to join forces and make your voice heard?
When people unite, they do more than seek compensation. They send a message that unfair practices won’t be ignored. Group litigation empowers consumers, challenges corporate behaviour, and can even influence law and policy for the better.
If you’ve been affected by wrongdoing, don’t face it alone. Collective action can give you the support and strength you need to hold powerful organisations to account.
