Starmer's government will bar under 16s from Snapchat, TikTok, YouTube, and X and extend the rules to online games, livestreams, and AI chatbots. How, when, and by whose standards that actually gets enforced remains undefined.
The UK government on Monday announced it will bar children under 16 from opening accounts on Snapchat, TikTok, YouTube, Instagram, Facebook, and X, packaging the move as one of the strictest youth-internet restrictions in the world, according to The Verge and the government's own announcement. Messaging apps WhatsApp and Signal are explicitly exempt.
The package, announced by Prime Minister Keir Starmer, reaches well beyond the six named platforms. It also blocks under-16s from talking to strangers inside online games and on livestreaming services, forces so-called romantic companion chatbots to enforce a minimum age of 18, and restricts "intimate functionalities" on general AI tools for minors, The Verge reported. Restrictions on these functionalities will also apply by default to 16- and 17-year-olds to prevent a cliff-edge at the age boundary.
Starmer framed the law as going further than any other country, citing Australia's prior under-16 social media ban — which took effect in December 2025 — as the benchmark. That "further than any other country" framing is a government assertion; the announcement does not specify in which categories the British rules are stricter than the Australian baseline, or how compliance will be measured. The UK government says it will introduce more highly effective age assurance (HEAA) measures, learning from Australia's experience, to make it harder for children to bypass safeguards.
The government plans to use secondary legislation under the Children's Wellbeing and Schools Act to introduce the protections, bypassing the need for new primary legislation. The first set of regulations could be in effect in Spring 2027, with the legislation expected to reach Parliament before Christmas 2026, according to the GOV.UK announcement. Ofcom, the UK's media regulator, is expected to play a central role, conducting a rapid study on effective age assurance and reviewing its enforcement capabilities. The specific enforcement tools — fines, app-store removals, prosecution — regulators will use against non-compliant platforms have not yet been spelled out.
Australia's ban is the closest international comparison, and the UK announcement frames itself as going further without spelling out which provisions would qualify as "further" in a measurable sense. Australia's own rollout has surfaced enforcement and definitional questions around age assurance, the boundary between "social media" and adjacent services, and the practical limits of blocking determined teenagers, and the British package will inherit those questions.
The Starmer government's stated rationale leans on a familiar critique of attention-capture design. "Infinite scroll: they're designed to lock you in for hours," Starmer said of the products his government now wants minors off. That critique is shared by researchers and child-safety advocates, but it does not by itself resolve the implementation gap between political ambition and a working compliance regime.
What to watch next: the text of the secondary legislation, Ofcom's rapid study on effective age assurance, the list of accredited age-verification providers, the government's further announcement on overnight curfews and infinite-scroll breaks for under-18s expected in July, and the first round of platform responses once the legal language is in front of the companies that would have to build it.
