The UK’s Ban on Social Media for Under-16s: Rules, Platforms, and Key Criticism

Which platforms are covered

The government’s fact sheet names ten platforms that will be off-limits to anyone under 16: TikTok, Snapchat, Instagram, YouTube, Reddit, Twitch, X (formerly Twitter), Threads, Facebook, and Kick . The list deliberately mirrors the Australian model, which also includes services such as Facebook, Instagram, TikTok, Snapchat, X, YouTube, Reddit, and Twitch among its restricted platforms . Messaging apps like WhatsApp and Signal are explicitly excluded, and child-focused products such as YouTube Kids will remain accessible .

When the ban takes effect

Starmer told reporters that the government intends to finalise the necessary regulations before Christmas 2026, allowing enforcement to begin early the following year, probably around spring 2027 . Technology Secretary Liz Kendall had earlier signalled that regulations for under-16s would be enacted by the end of 2026 . Companies will be required to deploy “robust age assurance” to prevent underage access, with Ofcom overseeing compliance .

How does the UK ban compare to Australia’s?

The UK government has been explicit: it plans to “use the same model for a social media ban as Australia” . Australia’s Online Safety Amendment (Social Media Minimum Age) Act 2024 came into effect on 10 December 2025 and already deactivated millions of accounts held by under-16s on platforms including Facebook, Instagram, TikTok, and Snapchat . Under that law, tech firms face fines of up to A$50 million (roughly £25.7 million) if they fail to take reasonable steps to block underage users .

Where the UK departs from the Australian blueprint is in its bolt-on restrictions for older teens. Alongside the under-16 social media ban, the government is prohibiting livestreaming and the ability for strangers to contact children on other online services for under-18s, and will outlaw romantic or sexual AI chatbots for the same age group . These measures sit on top of the UK’s existing Online Safety Act, giving regulators tools that Australia’s framework does not yet include .

The path to a ban: consultation and parliamentary process

The road from proposal to policy was anything but smooth. Here is how the key events unfolded:

• January 2026 – The House of Lords voted 261 to 150 to attach an amendment banning under-16s from social media to the Children’s Wellbeing and Schools Bill .
• March 2026 – MPs rejected that Lords amendment, voting 307 to 173 against an outright ban at that stage, while the government launched its own three-month national consultation called “Growing up in the online world” .
• March–May 2026 – The consultation attracted 81,283 responses, including 42,410 from parents and 13,890 from young people . The results were emphatic: 9 in 10 parents backed a social media ban for under-16s, and two-thirds of young people agreed that under-16s should not be on at least some social media platforms .
• Late March 2026 – The House of Lords voted again in favour of the ban, this time by 266 to 141, increasing pressure on the government .
• April 2026 – MPs rejected the ban for a second time, voting 256 to 150 against the Lords’ proposal, though ministers openly committed to introducing “some form” of age or functionality restrictions .
• June 2026 – Starmer ended the stalemate by announcing the government would proceed with a full ban, stating it was time to “give kids their childhood back” .

Key reactions from critics

The ban’s announcement was met with immediate pushback from children’s rights groups, digital privacy organisations, and the platforms themselves.

Amnesty International UK offered the most succinct critique. Chief Executive Kerry Moscogiuri called it “the right diagnosis but the wrong prescription,” warning that a blanket ban “risks driving children’s internet use underground, cutting them off from vital support networks, and failing to address the root causes of harm” . Amnesty was one of several human rights bodies to argue the problem lies with exploitative business models and algorithmic design, not the mere presence of children on platforms .

Other dissenting voices included:

• Scotland’s Children’s Commissioner, Nicola Killean, who warned there is “inadequate evidence” a ban would make children safer and argued it could push teens toward “less regulated or more dangerous sections of the internet” .
• Big Brother Watch, which said in a parliamentary briefing that the proposal would “fail to keep children safe and introduce serious unintended consequences” affecting the privacy rights of all internet users .
• A coalition of 42 children’s organisations and experts, who pointed out that evidence on whether bans improve young people’s mental health remains limited . Cambridge researcher Amy Orben, whose team studied the evidence for a government-commissioned report, noted there is little reason to expect “substantial boosts to well-being or mental health in the short term” from a ban alone .
• The Open Rights Group, which warned that enforcing the ban would require building a mass age-verification system carrying “serious risks to privacy, data protection, and freedom of expression” .

The tech industry has also pushed back strongly. Meta, TikTok, Snap, and YouTube all argued that the ban is disproportionate, that they already invest heavily in age-appropriate protections, and that a blanket approach could push young users “towards less safe services” .

The policy is now locked in, but the debate over whether it represents a necessary step-change in child safety or a blunt instrument with serious unintended side-effects is only just beginning. With regulations expected before the end of 2026, attention will soon shift to how Ofcom plans to enforce the age-assurance measures and whether the ban achieves its stated goal of making children meaningfully safer online.
