Do Proposed UK Restrictions on Under‑16s Reduce Online Harm, or Reframe It?

Proposals to restrict under-16s from accessing social media have shifted from policy debate to active legislative consideration. Governments across the UK, Ireland and Australia are facing rising concerns about children’s mental health, exposure to harmful content and platform designs that encourage compulsive use.

‍In the UK, the Government has so far avoided committing to a blanket ban. Instead, it has adopted a consultation-led approach, supported by provisions in the Children’s Wellbeing and Schools Bill that would allow restrictions on specific platform features. This reflects practical experiences identified by the House of Commons  social media use among teenagers is universal, age limits are widely avoided, and enforcement under the Online Safety Act has initially focused on the most extreme harms rather than systemic design issues.

‍Northern Ireland’s debate provides an instructive contrast. In February 2026, the Assembly passed a motion recognising the growing evidence linking social media use to harm, while also explicitly warning that restrictions alone are insufficient. The amended motion cautioned that an outright ban introduced prematurely or in isolation could push young people into less regulated online spaces, encourage widespread VPN use, and generate new safeguarding risks. It placed clear emphasis on holding multinational platforms accountable through regulation and sanctions.

Evidence from ARK’s Young Life and Times survey  reinforces this position. More than half of 16-year-olds in Northern Ireland report experiencing illegal or harmful behaviour online, with disproportionate impacts on girls, LGBTQ young people, and those from disadvantaged backgrounds. Young people consistently identify platform design features such as anonymity, disappearing messages and algorithmic amplification as key contributors to harm.

Similar concerns are being raised in the Republic of Ireland. Speaking at a meeting of the Oireachtas children’s committee representatives from youth organisations said teaching people digital literacy is a better approach. Child protection experts and policymakers have warned that a social media ban could push under-16s into darker, less visible online spaces. Irish debate has increasingly focused on platform accountability, digital literacy, and alignment with the UN Convention on the Rights of the Child, rather than reliance on access bans alone.

Australia’s experience offers tangible early evidence. Research commissioned by the Molly Rose Foundation  shows that while millions of under-16 accounts were removed following the December 2025 ban, three in five (61%) Australian 12–15-year-olds who had accounts on restricted platforms before the ban came into force, still have access to one or more accounts.

The core policy challenge is not whether harm exists, but whether age-based bans meaningfully reduce it. Without tackling platform design, accountability, enforcement and digital education, restrictions risk becoming tokenistic gestures that leave the structural causes of online harm largely untouched.
