In Britain, the idea of stopping children under 16 from using social media is moving from a public argument to a real policy debate. But as of March 25, 2026, the UK does not have a national under-16 ban. A proposal for such a ban was defeated in the House of Commons on March 9, 2026. Instead, the government has launched a national consultation called “Growing up in the online world,” which asks whether the UK should set a minimum age for social media, restrict addictive features like autoplay and infinite scroll, and even raise the digital age of consent. The consultation closes on May 26, 2026, and the government says it will respond in summer 2026. (commonslibrary.parliament.uk)
Still, important rules are already in force. Since July 25, 2025, the Online Safety Act has required platforms to protect under-18s from harmful content such as pornography, suicide and self-harm material, and eating-disorder content. Ofcom says platforms must use “highly effective” age checks where needed, and its child-safety codes include 50 measures covering age assurance, content moderation, and recommender systems. In other words, the UK is already moving toward tighter control, even without a full ban. (gov.uk)
Why is the pressure so strong? Because many children are already online far earlier than the rules suggest. Ofcom’s 2025 report found that 55% of children aged 3 to 12 were using at least one social media app or site, despite the common minimum age of 13. It also found that 34% of children aged 8 to 15 had a profile on at least one online service with a minimum user age of 16 or above. (ofcom.org.uk)
So what is the best way to protect children? The strongest answer is probably not one simple ban. A government-commissioned evidence review published on January 20, 2026, warned that serious harms to some children are real and urgent, but also said the evidence is still weak on whether simply cutting social media time improves mental health across the whole population. That suggests the smartest policy is a layered one: enforce age limits properly, redesign apps to reduce addictive features, give parents clearer tools, and teach children how to judge what they see online. A ban may sound strong, but safety will depend on better systems, not just stricter slogans. (gov.uk)
