The government of the United Kingdom has introduced a nationwide restriction preventing children under 16 from accessing social media platforms, in what officials describe as a major overhaul of online safety rules.
Prime Minister Keir Starmer announced the policy on Monday through a video statement published on his official X account. He said the measure is intended to reduce exposure to harmful online content and address growing concerns about youth mental health, online harassment, and exploitation.
Starmer said the decision follows extensive consultations with parents and child welfare groups, many of whom reported concerns about compulsive social media use and its impact on sleep, education, and family life. He added that the government would be prepared to enforce the law even against large technology companies.
According to the Prime Minister, the new rules are designed to limit what he described as algorithm-driven engagement patterns that keep young users continuously active on platforms. He argued that current digital environments expose minors to risks that are not adequately controlled by existing safeguards.
The policy targets major user-driven platforms, including TikTok, Instagram, Snapchat, Facebook, and X, which will be required to block users under 16. The legislation is expected to rely on mandatory age-verification systems, with enforcement overseen by the UK’s communications regulator, Ofcom.
Officials say more than 90% of parents consulted during the policy review supported stricter age limits, citing concerns about cyberbullying, harmful content exposure, and excessive screen time.
Under the new framework, companies that fail to comply could face significant financial penalties or be blocked from operating in the UK market. The government has also indicated that enforcement trials will begin immediately to test verification systems before full implementation.
