The UK is banning children under 16 from social media platforms including TikTok, Instagram, Snapchat, YouTube, Facebook, and X, with legislation expected to pass before the end of 2026 and enforcement beginning in spring 2027. Prime Minister Keir Starmer announced the ban on Sunday, calling it “a line in the sand.” “Tech giants had their chance and failed, but we’re stepping in to protect children, back parents and set a new normal for future generations,” he said in a speech at Downing Street.
Platforms will have to disable access for under-16 users by default — blocking account creation for that age group rather than relying on self-declaration of age. The restrictions go beyond social media: children under 16 will also be barred from chatting with strangers in gaming apps, from livestreaming, and from using romantic chatbots. Messaging apps like WhatsApp and Telegram fall outside the scope of the ban. The government is also weighing separate rules for under-18s, including overnight usage curfews and mandatory breaks in infinite-scrolling feeds. Ofcom, the UK’s communications regulator, will write the detailed enforcement rules in consultation with lawmakers.
The UK’s approach follows Australia, which enacted a comparable ban on December 10, 2025. UK ministers visited Australia to examine how the law was being enforced before proceeding with their own version. Within a month of Australia’s ban taking effect, Meta had shut down around 550,000 accounts to comply. The UK government’s own “Growing up in the online world” consultation, launched in January, found nine in ten parents support a minimum age of 16 for social media access.
Starmer pre-empted the obvious objection — that teenagers will simply find workarounds — by comparing it to the argument that alcohol shouldn’t be restricted for minors because some manage to obtain it anyway. “Our laws are rules, but they’re also an expression of our values. They shape the social contract, and so this will change the conversations that parents have and the expectations of children over time,” he said. The government’s press release describes the UK’s scope as going “further than any other country,” citing the combination of social media restrictions, gaming rules, and livestreaming limits. Starmer also pushed back on any suggestion the ban signals hostility to the tech sector: “I do not accept, and I will never accept that you can’t be both pro tech and AI, and at the same time say we must protect our children.”
The practical test now lands with Ofcom. The UK’s Online Safety Act had already required platforms to meet age-assurance standards, but technical enforcement at scale — verifying that a user is genuinely over 16 without requiring a government ID check from every new account — has proven contentious. Platforms like TikTok and Snapchat, which depend heavily on their under-20 user base for engagement, face the largest compliance burden. The spring 2027 enforcement date gives them roughly a year to build or adapt age-verification systems to meet the new standard.
