The UK government is under growing pressure to take stronger action against social media platforms following mounting concerns about the impact of online harms on children and teenagers.
After meeting bereaved families and campaigners earlier this week, Prime Minister Sir Keir Starmer said the government would take “decisive” action and promised reforms that would be a “game-changer”.
Options under consideration reportedly include a social media ban for under-16s, stronger age verification measures, app curfews, and restrictions on features such as infinite scroll and autoplay.
While the political debate currently centres on child safety, regulation, and platform accountability, there is another question beginning to emerge in the background: Could the UK eventually see large-scale legal claims linked to alleged social media harms?
Why pressure on social media companies is increasing
For years, concerns around social media were often framed as parenting or wellbeing issues. But that conversation is now changing rapidly.
Campaigners, doctors, politicians, and regulators are increasingly focusing on whether some platform features are intentionally designed to maximise engagement in ways that may create risks for younger users.
Much of the current debate focuses on:
- Addictive design features such as endless scrolling and autoplay
- Algorithmic recommendation systems
- Exposure to harmful or distressing content
- Online bullying and harassment
- Inadequate age verification
- The impact of excessive social media use on mental health and sleep.
The government’s consultation reportedly received more than 80,000 responses from parents, children, charities, and campaign groups. That level of public engagement reflects how mainstream these concerns have now become.
The language used by parts of the medical profession is also becoming noticeably stronger.
This week, the Academy of Medical Royal Colleges described social media as a public health issue comparable to smoking or seatbelts, warning that “unfettered exposure” to technology and devices was causing increasing harm to children and young people.
According to the Academy, more than half of doctors surveyed reported seeing potential technology-related harm in children at least weekly, with concerns ranging from exposure to violent or sexual content through to sleep disruption, anxiety, trauma, and other mental health impacts.
The Online Safety Act already places new duties on platforms operating in the UK, particularly around protecting children from harmful content. But some campaign groups argue the legislation does not go far enough. The current consultation suggests the government may now be considering additional restrictions beyond the existing framework.
Questions are also being asked about whether the platforms themselves are doing enough to limit the harm they allegedly cause. And whether they should be held accountable.
The legal landscape is also evolving
At the moment, the UK has not seen the same scale of social media litigation that has emerged in parts of the United States. However, globally, legal pressure on technology companies is increasing.
In the US, there have already been lawsuits alleging that social media platforms knowingly designed products to encourage compulsive use among children and teenagers. Some cases have focused on whether companies adequately understood — and responded to — the potential mental health impacts of their platforms.
In California, a jury awarded $6m (£4.5m) in damages to a claimant who alleged that social media use during childhood contributed to serious mental health harm. Jurors found that platform design played a role in that harm. In a separate case in New Mexico, Meta was ordered to pay $375m (£279m) following findings related to child safety and exposure to harmful content.
Meanwhile, in the UK, the wider collective actions market continues to grow
Over the last few years, group claims relating to data breaches, competition law, consumer rights, and digital markets have become increasingly common. Courts and regulators are also placing greater scrutiny on how large organisations manage risk, transparency, and consumer protection.
That does not automatically mean social media harm claims are imminent in the UK. These cases would likely face complex legal and evidential challenges. But the direction of travel is becoming harder to ignore.
Could this become the next major area of group litigation?
It is still too early to say. But history shows that large-scale litigation often follows periods of growing public concern, regulatory scrutiny, and increased awareness of potential harm.
If stronger restrictions are introduced — particularly around addictive design features or child safety protections — it could also influence how future legal claims are framed.
The government is expected to publish its response to the consultation later this year, with potential measures for under-16s expected before the end of 2026.
Whatever approach is ultimately adopted, one thing is becoming increasingly clear. The debate around social media is shifting away from whether platforms influence young people’s wellbeing — and towards how much responsibility technology companies should bear when harm allegedly occurs.
