In the early stages of a high-profile UK consumer claim, one seemingly small detail can surprise any legal team. Your funding is secured, counsel appointed and the legal theory sound. Yet weeks after launch, claimant numbers are lagging well behind expectations. Nothing was ‘wrong’ legally. The issue was simpler: too few people understood the claim, trusted it, or saw themselves in it.
That moment reflects a growing reality in the UK market. Class action communications have become one of the decisive factors in whether mass litigation stalls or scales.
What is a class action?
A class action is a legal claim brought by one or more claimants on behalf of a wider group who have suffered the same or similar harm.
In the UK, these cases often take the form of group litigation orders, opt-out competition claims or large-scale collective actions supported by litigation funders. They exist to make redress possible where individual claims would be impractical or uneconomic.
The mechanism sits in law. The momentum sits elsewhere.
Why class actions are accelerating in the UK
Mass claims have moved firmly into the mainstream of UK litigation, and economic pressure plays a major role. During downturns, scrutiny intensifies; consumers question fees and contracts, employees push back on working practices, and investors and regulators demand accountability. Collective action feels both necessary and justified.
Structural change has also lowered barriers. The UK’s collective action regime has matured, particularly in competition law with the Competition Appeal Tribunal, while London’s global standing continues to attract international claimants. At the same time, public awareness has grown. Claimants now understand that collective redress exists and that participation carries limited personal risk.
Class actions in the UK are increasingly diverse. They can involve consumer rights, where large groups of customers seek redress for unfair pricing or contract terms; environmental cases, holding companies accountable for damage or regulatory breaches; employment disputes, where systemic workplace issues are challenged; or sector-wide financial and service-based claims. Each type carries its own challenges and communications considerations, from building awareness to sustaining engagement among large claimant groups.
These forces combine to create fertile conditions for mass litigation, but only for claims that gain traction beyond the courtroom.
When legal strength is not enough
Many mass claims falter not because of weak legal arguments, but because they fail to mobilise.
Claimants do not join cases simply because they exist. They join when they recognise themselves in the harm, understand the process and believe the claim will be handled responsibly. Media, campaign groups, and defendants all influence this perception. Without a clear narrative, the story fragments. Misunderstanding spreads, and trust erodes.
This is where class action communications shift from a support function to a strategic lever. It shapes how claims are understood, discussed and remembered.
Economic pressure changes how claims are received
In periods of financial strain, collective claims take on wider meaning. They come to represent fairness, accountability and access to justice at a time when many people feel systems are working against them.
That visibility brings sharper scrutiny. Questions quickly follow about who benefits, how claims are funded and how much compensation ultimately reaches those affected. As mass litigation becomes more mainstream, public awareness is increasingly driven by digital channels such as paid search, social advertising and targeted outreach that promise potential financial returns.
These ads work, but they also shape perception. Messaging that leans too heavily on headline figures or implied windfalls can raise expectations that no legal process can guarantee. When reality fails to match the promise, credibility suffers not just for the claim but for those leading it. Critics point to cases where legal fees and litigation funders’ returns appear to dwarf individual payouts, challenging the idea that mass claims always deliver meaningful redress.
For law firms, the biggest challenge that arises from class action communciations is balance. Claimants need clarity and reassurance, not hype. The wider public expects transparency without oversimplification. Integrated communications helps align digital activity with legal reality, ensuring that awareness-building does not undermine trust as scrutiny intensifies.
Integrated communications play a critical role here by aligning legal strategy with public understanding, ensuring consistency across media, digital channels and claimant touchpoints as scrutiny intensifies.
Claimant confidence is built, not assumed
Claimant confidence does not emerge automatically, even in opt-out actions.
People engage when they trust the organisation behind the claim. They stay engaged when updates feel timely and credible, and this turns to advocacy when they feel informed, rather than marketed to.
This applies across consumer, environmental and competition claims. It also applies across jurisdictions, particularly in cases involving international harm, but UK courts, such as with the UK’s largest environmental class action over the Mariana Dam collapse.
Firms that treat communications as part of case architecture, rather than a bolt-on, tend to build stronger and more resilient claims.
What this means for law firm leaders
For partners and senior lawyers leading mass litigation, communications now sit alongside funding and legal theory as a core consideration. As competition for claimant attention increases, firms that invest in class action communications early tend to control the narrative rather than react to it.
That control increasingly shapes outcomes beyond the courtroom.
The UK is likely to see continued growth in mass claims, particularly during ongoing economic uncertainty. The firms that succeed will be those that combine legal rigour with a clear, responsible public narrative that supports claimants, withstands scrutiny and evolves with the case.
In mass litigation, momentum is rarely accidental.
More from us
PHA works alongside law firms, funders and claimants on complex, high-profile disputes where reputation, trust and public understanding shape outcomes as much as legal process.
As an earned-first integrated communications agency, we help cases cut through crowded, fragmented landscapes with clarity and credibility, combining litigation communications, media strategy, digital and stakeholder engagement into one joined-up approach.
Our experience spans consumer, competition and environmental litigation, including communications support for a landmark environmental class action following the collapse of the Mariana dam in Brazil. This work required long-term, sensitive storytelling focused on accuracy, human impact, and multi-jurisdiction engagement, including PR support for the Dead River podcast, which detailed the case and amplified the voices of those affected.
If you’re leading or preparing a mass claim and need communications support that evolves with the case, our team of specialists are ready to help. Get in touch at hello@thephagroup.com to get the conversation started.
