Millions of children across Britain are set to lose access to some of the world’s most popular social media platforms under sweeping new legislation that ministers are describing as the most significant child protection measure of the internet era.
Prime Minister Sir Keir Starmer has announced plans to ban under-16s from accessing major social media services including TikTok, Instagram, Snapchat, Facebook, X and YouTube, arguing that governments can no longer stand by while technology companies exert unprecedented influence over children’s lives.

The legislation, expected to be passed before Christmas and come into force in spring 2027, marks one of the most ambitious attempts by any Western government to fundamentally reshape the relationship between young people and digital technology.
Declaring that he was “not prepared to compromise on the safety and happiness of our children”, Starmer framed the move as a defining intervention in what has become one of the most contentious public policy debates of the modern age.
The Prime Minister’s decision follows years of growing concern over the impact of social media on childhood, with mounting evidence linking excessive platform use to anxiety, depression, sleep disruption, cyberbullying, exposure to harmful content and addictive online behaviours. While previous governments focused primarily on regulating content, Starmer’s administration has concluded that more radical action is required.

The result is a policy that could remove millions of British teenagers from social media platforms entirely until they reach the age of 16.
Under the proposals, social media companies will be required to implement robust age-verification systems to prevent children from accessing their services. Adults over 16 may also face age checks, although ministers say many users will be exempt because their identities have already been verified through linked payment methods, email authentication or existing account histories.
The measures extend beyond traditional social media platforms. The Government has also announced a ban on intimate and sexual conversations between under-18s and artificial intelligence chatbots, reflecting growing concern about the rapid emergence of AI-powered companion technologies.
Restrictions will additionally be placed on some features commonly used by younger audiences. Children under 16 will be prevented from livestreaming on certain services and from being contacted by unknown adults through online platforms. Although gaming platform Roblox and messaging services such as WhatsApp and Signal will remain accessible, some safety-related limitations are expected to apply.
Ministers are also examining whether 16 and 17-year-olds should face restrictions on features such as infinite scrolling and late-night access, amid increasing evidence that platform design itself contributes to excessive screen use.
The announcement represents a dramatic shift in Britain’s approach to online safety and places the country at the forefront of an international movement seeking to impose stricter limits on children’s digital lives.
Australia became the first major democracy to introduce a nationwide social media ban for under-16s in 2024, a move that attracted global attention and inspired similar discussions across Europe and North America. Britain is now following that path, although some elements of the proposed legislation may go further than the Australian model.
The decision follows an extensive three-month consultation that attracted more than 116,000 responses, making it one of the largest public consultations in recent government history. The results revealed overwhelming support among parents for tougher measures. Nine out of ten parents who participated backed a social media ban for under-16s, while more than 83 per cent said the risks associated with social media outweighed its benefits.
For ministers, those figures provide a powerful democratic mandate.
Technology Secretary Liz Kendall said the reforms were designed to “take power away from the tech giants” and represented a necessary response to years of inadequate action by major technology companies. The Government argues that platforms have repeatedly promised to improve child safety but have failed to address fundamental concerns about harmful content, addictive algorithms and online exploitation.
“This is not one and done,” Kendall warned, signalling that further regulation may follow.
The policy has been welcomed by many campaigners who have spent years pressing for stronger protections. Among them is Joe Ryrie, co-founder of the Smartphone Free Childhood movement, which has become one of the most influential grassroots campaigns in Britain on children’s digital wellbeing.
“This social media ban won’t solve every problem overnight,” he said, “but it is a major step forward.”
Supporters argue that social media platforms were never designed with children’s developmental needs in mind and that young people are effectively participating in a vast, uncontrolled experiment involving algorithms engineered to maximise engagement.
For bereaved families who have lost children following harmful online experiences, the announcement carries particular emotional significance.
Esther Ghey, whose daughter Brianna was murdered in 2023, welcomed the move and suggested it could save lives.
One of Brianna’s killers reportedly became fascinated with violent online material, including videos depicting murder and torture.
Ghey described the Government’s intervention as a potentially transformative step but cautioned that children affected by the ban would require support as society adjusts to a fundamentally different digital landscape.
Despite broad public support, the legislation has sparked fierce debate among child welfare experts, digital rights advocates and technology companies. Major social media firms have responded with unusual force.
Meta, the parent company of Facebook and Instagram, warned that blanket restrictions could isolate teenagers from valuable communities, educational content and support networks.Snapchat similarly argued that while it supports efforts to improve online safety, banning access altogether risks creating unintended consequences.
YouTube mounted one of the strongest defences, describing itself as an important educational resource used by students, teachers and parents.
The company argued that removing children from supervised and curated online environments may simply push them towards less regulated and potentially more dangerous alternatives.
“Blanket bans push kids towards anonymous, less safe servces,” the company said.
The criticism highlights a central challenge facing policymakers worldwide.
While concerns about social media harms are widespread, experts remain divided on whether access bans represent the most effective solution. Several prominent child protection organisations have expressed reservations.
Rocio Cifuentes, the Children’s Commissioner for Wales, argued that the policy places excessive emphasis on children’s behaviour rather than platform accountability.
Her counterparts in Scotland and Northern Ireland voiced similar concerns, warning that the measures may prove difficult to enforce and could allow technology companies to evade responsibility for making their services safer.
The Molly Rose Foundation, established following the death of 14-year-old Molly Russell after exposure to harmful online content, has also questioned whether bans alone address the root causes of digital harm. Research from Australia has reinforced those concerns.
Despite that country’s social media restrictions, studies suggest many young people continue to access prohibited platforms. One survey found that 61 per cent of 12-to-15-year-olds with existing accounts retained access even after restrictions were introduced.
Those findings have fuelled scepticism among critics who argue that determined teenagers will inevitably find ways around technological barriers. Supporters insist that focusing solely on enforcement misses the broader objective.
Government ministers increasingly view the legislation not simply as a policing measure but as an attempt to reshape social norms. Just as smoking bans transformed public attitudes towards tobacco, proponents believe social media restrictions could gradually alter expectations about childhood, screen use and digital engagement. The political significance is therefore viewed as extending beyond child protection.
The announcement comes at a time when governments across the Western world are grappling with growing public anxiety over the influence of large technology companies. Once celebrated as engines of innovation and connection, social media platforms now face accusations that they have prioritised growth and profit at the expense of user wellbeing.
The Prime Minister’s intervention also reflects a remarkable transformation in public attitudes.Only a decade ago, social media was widely celebrated as a tool for empowerment, creativity and connectivity. Today, many parents view it with suspicion, and increasing numbers of young people themselves report feeling overwhelmed by the pressures it creates.
T The practical challenges of age verification, enforcement and technological circumvention are formidable. Legal battles with technology firms appear likely. Critics warn of unintended consequences, while supporters insist the risks of inaction are greater still.
Social media has become an almost permanent feature of daily life for the first generation who grew up entirely online. Starmer’s reforms seek to interrupt that reality and redefine where childhood ends and the digital world begins.
If implemented successfully, the legislation could become one of the most consequential child protection reforms of the twenty-first century. If it fails, it will nevertheless mark a historic moment when a government decided that the age of unrestricted access to social media for children had gone too far. The battle over childhood in the digital age has been building for years. With this announcement, Britain has chosen a side.
