Prime Minister Sir Keir Starmer intends to ban under-16s from major social media platforms including TikTok, Snapchat and Instagram, BBC News reported on 14 June 2026.

The move would go further than the Online Safety Act 2023, which already requires social media companies to protect children by detecting and managing harmful content. That Act created a duty-of-care framework — a set of obligations on platforms to safeguard users. The government now appears to be considering a harder measure: simply preventing under-16s from accessing these platforms altogether. Ofcom, the regulator enforcing the Online Safety Act, was asked in November 2024 to study social media's effects on children; those findings will now inform policy discussions that have shifted considerably since that commission was given.

The scale of use is substantial. A joint UK-US statement from October 2024 found that more than six in ten 13 to 17-year-olds in both countries reported using TikTok, Snapchat and Instagram. That figure — agreed between Technology Secretary Peter Kyle and his US counterpart as part of the first formal UK-US online safety cooperation agreement — has become central to how the UK government frames the problem. An age ban for under-16s would affect a very large share of current adolescent social media use.

The wider youth policy picture

This announcement does not stand alone. Since July 2025, the government has opened Young Futures Hubs in eight areas experiencing high rates of knife crime and antisocial behaviour, offering support to vulnerable young people. A second wave launched in April 2026, designed to reverse the long-term decline in statutory youth services available to teenagers.

The December 2025 National Youth Strategy set out a 10-year plan to give 500,000 more young people access to a trusted adult outside the home and build their life skills. The strategy explicitly named online safety regulation — including enforcement of the Online Safety Act — as one of its main pillars. This frames digital policy within a broader youth welfare agenda rather than treating it as a technology question alone.

Culture Secretary Lisa Nandy holds departmental responsibility for the youth strategy. Any social media ban, however, would fall primarily under the Technology Secretary's remit. The practical detail of a ban — how age verification would work, what liability platforms face, how people could appeal — may require new primary or secondary legislation beyond what the Online Safety Act's existing framework can accommodate.

The technical challenge

Age-based exclusion sounds straightforward but enforcement is not. Age verification at scale requires either government-issued identity infrastructure, asking platforms to verify users themselves, or a hybrid approach — each raises data-protection concerns under UK GDPR. Australia passed a comparable ban for under-16s in late 2024, and its rollout has exposed these tensions between rigorous verification and protecting privacy.

The government has not yet published draft legislation. The BBC report notes that the Prime Minister's intention has been reported, but a timeline has not been confirmed. At this stage, the ban remains a stated policy direction rather than a committed legislative schedule.

What is clear is the government's direction of travel. The Online Safety Act, Ofcom's children's research, the UK-US cooperation agreement, the National Youth Strategy, and now the reported intention to legislate an age ban together form the most comprehensive policy apparatus on children's online safety that any UK government has assembled. Whether the regulatory machinery can keep pace with the policy ambition remains an open question.
