UK to Ban Children Under 16 From Major Social Media Platforms
The new rule targets the platforms themselves, not the children. If a service fails to remove or block under‑16 accounts, it faces multimillion‑pound fines. The ban does not cover YouTube Kids or messaging apps such as WhatsApp and Signal, which the government says are already subject to separate safeguards.
Starmer said the decision follows a consultation that attracted 116,000 responses, more than 90 % of which supported a minimum age of 16. The consultation was the second‑largest public‑comment exercise in the UK since the 2012 same‑sex marriage debate. The government will use the data to shape the final regulatory framework.
The UK’s move mirrors Australia’s 2025 law that made it illegal for anyone under 16 to hold a social‑media account. Australia’s ban, which came into force on 10 December 2025, has already sparked a global conversation about child protection online. Canada, Brazil and Indonesia have also introduced or announced similar age‑based restrictions.
In addition to the account ban, the government will consider measures to prevent strangers from contacting children on gaming and livestreaming platforms. The policy package may also include overnight curfews and mandatory breaks in infinite‑scroll feeds for users under 18, according to a statement from the department.
Reactions were mixed. The NSPCC praised the government’s ambition but urged that platforms implement robust age‑verification tools and enforce the policy consistently. The Open Rights Group warned that age‑verification services could compromise user privacy and that the ban might drive children to less‑regulated, anonymous services. A spokesperson for YouTube said that blanket restrictions could push children away from supervised, curated experiences and toward anonymous, potentially unsafe platforms.
The United States has expressed concern that the UK’s regulation could impose additional burdens on American technology companies. The U.S. Embassy in London issued a statement urging that regulations remain narrow and respect free‑speech protections.
Starmer said he would discuss the policy with President Donald Trump and other world leaders at the Group of Seven summit in France, which begins on Monday.
The ban is part of a broader UK strategy to protect children from harmful content and excessive screen time. The Online Safety Act already requires platforms to remove or restrict content that is illegal, harmful or potentially harmful to minors. The new age‑restriction rule expands that duty to the very first step of account creation.
The policy will be enforced through a regulatory framework that includes fines for non‑compliance. The government has not yet released the detailed regulatory guidance, which is expected in the coming weeks.
The ban is likely to have significant implications for the technology sector. Companies that rely on a large under‑16 user base, such as TikTok and Instagram, will need to adjust their user‑verification processes and may face legal and financial penalties if they fail to comply.
The policy also raises questions about data privacy, as age‑verification systems will need to confirm users’ identities. The government has indicated that it will work with platforms to ensure that any data collected for verification purposes is handled in compliance with the UK General Data Protection Regulation.
In the short term, the ban will reduce the number of children who can create new accounts on the targeted platforms. The long‑term impact on child safety and mental health remains to be seen, but the government has framed the policy as a necessary step to protect children from harmful content and excessive screen time.
The UK will continue to monitor the implementation of the ban and may introduce further measures, such as restrictions on content that encourages risky behaviour or that is tailored to minors. The government has said it will keep the policy under review and will consult with stakeholders as it rolls out the new regulations.
The policy is part of a global trend toward stricter online‑safety laws for children. While the UK’s approach is similar to Australia’s, it is described by the Prime Minister as “Australia plus”, indicating that the UK will add additional safeguards and enforcement mechanisms.
The ban will take effect in early 2027, and the government will begin enforcement actions against platforms that do not comply. The policy is expected to influence the broader digital‑rights debate in the UK and internationally.
The policy’s success will depend on the effectiveness of age‑verification tools, the cooperation of technology companies, and the ability of regulators to enforce compliance. The government has signalled that it will not compromise on child safety and will take action against any platform that resists the ban.
