The UK's under-16 social media ban: What it means for the young people you work with

On 15 June 2026, the government did something it had been circling for years: it announced plans to bar social media platforms from offering their services to children under 16. Prime Minister Keir Starmer called it a line in the sand. Technology Secretary Liz Kendall framed it as a decisive step towards a safer, healthier life online for children and the generations that follow.

For anyone working in talking therapies, this is more than a policy story. Mental health sits at the very centre of the government's case, which means the debate now playing out in Parliament and the press is, in large part, a debate about the young people you sit with each week.

This article looks at what the proposals actually cover, why mental health has become the heart of the argument, what the research genuinely supports (and what it does not), and what all of it might mean for your practice.

What the proposals actually cover

Under the government's proposals, the ban would apply to user-to-user platforms built around social interaction, the kind that let people post content, together with the algorithms that decide what everyone sees next. The government has named TikTok, Snapchat, Instagram, Facebook, X and YouTube, though how each service is finally classified, YouTube included, will hinge on the detail of the regulations. Private messaging apps such as WhatsApp and Signal are not in scope, and YouTube Kids is excluded. In broad shape, the plan follows Australia, which switched on its own under-16 ban in December 2025.

Ministers have signalled they want to go further than a simple age gate. Expect additional limits on higher-risk features such as livestreaming and contact from strangers, reaching a wider set of services including gaming sites. To avoid a sudden cliff-edge the moment a child turns 16, these feature-level restrictions are likely to stay switched on by default for 16 and 17 year olds. Overnight curfews and a brake on infinite scrolling for under-18s are also on the table, with more detail expected in July. Separately, AI companion chatbots designed to simulate romantic or sexual relationships will have to enforce a minimum age of 18.

The legal route is already in place. The Children's Wellbeing and Schools Act 2026, which received Royal Assent on 29 April 2026, inserted a new power into the Online Safety Act 2023. It lets the Secretary of State bring in age-based or feature-based restrictions through secondary legislation, sidestepping the need for a fresh Act of Parliament each time. The government has committed to a progress report within three months of Royal Assent, and to laying regulations within twelve months after that. Measures could reach Parliament before Christmas, with the first regulations potentially in force by spring 2027. Ofcom, meanwhile, has been asked to run a rapid study on workable age assurance and to review how it would enforce the rules.

The announcement followed one of the largest public consultations the government has run, Growing up in the online world, which ran from March to May 2026 and drew more than 116,000 responses. According to the government, around nine in ten parents who took part backed a ban for under-16s, and roughly two-thirds of young people agreed that under-16s should be kept off at least some platforms. It is worth reading these figures for what they are: responses from a self-selecting consultation rather than a representative national poll, so they capture the views of those who chose to engage.

Why mental health is doing the heavy lifting

The policy rests on a worry that has been building for years across paediatrics, psychiatry, psychology and general practice: that the steady rise in anxiety, depression and distress among young people is being shaped, at least in part, by social media's always-on presence in their lives.

Clinicians have not been quiet about it. A group of UK practitioners, writing in Child and Adolescent Mental Health in 2025 (Skinner and Foljambe), argued that social media feeds into a whole spectrum of harm, anxiety, depression, eating disorders, body dysmorphia, self-harm and suicidality, and that the children who can least afford it, including neurodivergent young people and those facing socioeconomic disadvantage, tend to be hit hardest. Drawing on WHO and HBSC survey data, they noted that around 11 per cent of adolescents show signs of problematic, addiction-like patterns of use, and that in England around one in five 11-year-old girls already meets survey-based criteria for problematic social media use (a measure that, importantly, is not the same thing as clinical addiction).

Researchers have proposed several mechanisms by which social media might contribute to poorer wellbeing, and they will be familiar to anyone who works with young clients: disrupted sleep from late-night use, compulsive checking driven by variable rewards such as likes, comments and fresh content, exposure to distressing or extreme material through algorithmic feeds, and the reinforcement of vulnerabilities a young person already carries. Evidence for some of these pathways is growing, but the relative weight of each is still debated, and none should be treated as a settled causal route.

What the evidence really shows

For a practitioner audience, it is worth being straight about the science, because it is messier than the headlines let on.

The broad picture is this: heavier social media use is linked to poorer mental health through small but fairly consistent associations, and those associations are sharpest among young people who meet the threshold for problematic use. Small individual effects matter more than they sound, because exposure is now close to universal. OECD PISA data suggests 15 year olds spend more than 30 hours a week on digital devices for learning and leisure combined, and WHO and HBSC survey data finds that around a third of 11 to 15 year olds describe themselves as more or less permanently connected.

What the evidence has not pinned down is causation. Much of the research is cross-sectional and measures how long young people spend online rather than what they actually do there, which makes cause and effect hard to untangle. A child who is already anxious or low may simply use social media differently, rather than the platform being the source of the pain. This is why many researchers describe the case for a ban as precautionary rather than proven: the potential scale of harm, they argue, justifies acting before the science is fully settled, much as public health has acted on other risks.

And there is another side worth holding onto. Social media also offers real benefits, connection, identity exploration, peer support, a way to keep relationships alive, especially for young people who feel isolated offline. Which is why a growing number of researchers insist that how a young person uses these platforms matters as much as how much. It is also the backbone of the strongest argument against a blanket ban: for some young people, LGBTQ+ teenagers, neurodivergent teenagers, those who are geographically cut off, online communities can be a primary source of belonging. Take that away without offering anything in its place, and you may have removed a lifeline rather than a hazard.

For that reason, some clinicians and academics are wary of prohibition as a tool. Some commentators have drawn parallels with adolescent alcohol use, arguing that prohibition alone may not eliminate access and could simply push children towards the less regulated corners of the internet. Expert reactions to the announcement have pressed the point that policy affecting millions of children ought to be evidence-led, and have warned against reaching for a technological fix to what are, in part, social problems.

So, will it actually work?

Here is a distinction that tends to get flattened in the public conversation. The evidence that problematic use is associated with poorer mental health is considerably stronger than the evidence that an age-based ban will improve mental health across the population. The worry about online harm is widely shared; direct proof that nationwide age limits reduce that harm in practice is thin, partly because very few comparable bans have run long enough to study. Showing that social media can contribute to harm is not the same as showing that a ban will reduce it, and that gap is much of why the debate rumbles on among researchers and clinicians who otherwise agree the underlying concern is genuine.

What this means for your practice

Whatever you make of the proposals, they are likely to reshape the ground on which you work with young people, and they raise a few questions worth sitting with now.

The first is the gap between regulation and care. Restricting access does not, by itself, create a single extra hour of mental health support, and for some young people an online space has been the first, or only, place they went looking for help. Where a digital community disappears, the need it was meeting does not. You may well find this surfacing in the room, especially with clients who have used online networks to make sense of identity, neurodivergence or experiences they could not yet name elsewhere.

The second is the opening the policy creates to talk about use rather than simply access. Questions around digital literacy, sleep, help-seeking and online behaviour are likely to remain relevant regardless of where policymakers eventually draw the line, and they are questions therapists, families and schools all have a stake in. For anyone seeing children and adolescents, asking routinely about social media use, alongside the presenting concern, is increasingly part of a thorough assessment.

The third is the conversation with parents. Families have been among the loudest voices behind this change, and many will walk in carrying strong feelings: relief for some, anxiety about enforcement and workarounds for others. Helping a parent hold a measured, developmentally informed view, rather than a purely restrictive one, is likely to be some of the most valuable work of the months ahead.

Questions worth keeping in mind

When you are sitting with a young person against this backdrop, a few questions can help anchor the work:

• How central are online communities to this young person's support network, and what would actually be lost if they vanished?
• Is social media disrupting sleep, or feeding late-night patterns that drag on mood and functioning?
• Might algorithmic feeds be reinforcing anxiety, body-image worries or self-harm-related content?
• How does the young person themselves feel about the proposed restrictions, and do they experience their own use as helpful, harmful, or both?
• What offline sources of connection and belonging exist, and how might they be strengthened?

Holding both things at once

The proposed under-16 ban is a genuinely significant moment in how this country thinks about children and technology, and it has been argued, above all, on mental health grounds. The clinical concern behind it is real, and widely shared. Yet the evidence base is still maturing, the question of causation remains open, the proof that a ban will actually help is thinner still, and prohibition brings risks of its own.

For practitioners, the task may be to hold both truths in the same hand: to take young people's distress entirely seriously, while resisting the comforting idea that any single measure will fix it. The real work, understanding each young person's relationship with the online world and helping them find their way through it, will matter every bit as much after a ban as it does today.
