For a parent, the proposal is easy to picture. The account a fourteen-year-old might open on a Saturday morning would no longer be theirs to open. For the platform on the other side of that sign-up screen, the change is harder to deliver, because it has to tell a fifteen-year-old apart from someone a year older, reliably and at the scale of every new account.
On 15 June 2026 the government set out plans to stop under-16s from holding social media accounts in the UK. The proposal sets a minimum age of sixteen for named platforms, with the duty falling on the companies rather than on children or their parents. It was framed by the government as a move to give children “their childhood back”, and it goes further than the Australian model that came into force in December 2025.
What is in scope
The plans name the large social platforms where most under-16s spend their time, including Snapchat, TikTok, YouTube, Instagram, Facebook and X. Private messaging apps such as WhatsApp and Signal are not intended to be covered. Alongside the account ban, the government has proposed extra limits on specific features for under-16s, including livestreaming and contact from adults the child does not know.
Enforcement is aimed at platforms, not families. Companies that fail to take reasonable steps to keep under-16s off their services would face significant fines. The government has not published the penalty levels for the new regime, so the figures attached to existing online safety enforcement are the better guide to how seriously this is being taken.
The consultation behind the announcement
The proposal follows a national consultation, “Growing up in the online world”, which ran until 26 May 2026 and drew 116,211 responses, one of the largest public responses the government has had on a question of this kind. Ninety per cent of parents who responded said they would support under-16s not being allowed on social media. More than eight in ten said the risks of social media for children outweigh the benefits.
Those numbers matter because they change the political weather. A measure that looked contested a year ago now has a large, documented public mandate behind it, and that is what the government has chosen to act on.
How Parliament arrived here
The idea has taken a winding route. In January 2026 the House of Lords backed an amendment that would have required platforms to block under-16s within a year. The House of Commons preferred more flexible powers for ministers and sent the question to the national consultation instead. The June announcement is the government acting on the result, adopting a firmer position than it held for much of the past year.
The proposal is not yet law. It needs legislation to take effect, and the detail will be shaped as a bill moves through Parliament. Platforms planning ahead should treat the direction as settled and the specifics as still moving.
What the under-16 plans mean for age verification
Whatever final shape the policy takes, platforms are left with one concrete task. They have to establish how old a user is, accurately enough to satisfy a regulator, without pushing away the adults who are entitled to use the service.
This is not new ground. Under the Online Safety Act, sites that can be accessed by children have already had to use age assurance Ofcom considers highly effective, a duty that has applied to pornography services since July 2025. Ofcom has since opened investigations into dozens of services and issued several fines, so the enforcement around age checking is live rather than theoretical.
The under-16 proposal extends that same underlying requirement to the mainstream social platforms. The debate in Westminster is about who should be kept off these platforms. The task it leaves with the platforms themselves is more concrete: establishing, accurately and at scale, who is being let in.
Under-16 social media ban: common questions
Is the under-16 social media ban law yet? No. It is a government proposal announced on 15 June 2026 and it needs legislation to take effect. The detail will be settled as a bill passes through Parliament, so the direction is firm while the specifics are still moving.
Which platforms are in scope? The plans name the large social platforms, including Snapchat, TikTok, YouTube, Instagram, Facebook and X. Private messaging apps such as WhatsApp and Signal are not intended to be covered by the under-16 account rule.
Who is responsible for enforcing it? Enforcement is aimed at the platforms, not at children or parents. Companies that fail to take reasonable steps to keep under-16s off their services would face significant fines under the regime once it is in force.
