UK under-16s social media ban: which apps will be blocked and how will it work?

Keir Starmer has announced plans to bar under-16s from major social media platforms in the UK, setting up one of the most significant online-safety interventions yet proposed for children.

The government says the policy is aimed at services it classifies as high risk for children. It follows a consultation that drew more than 116,000 responses, with ministers saying about 90% of parents who replied backed raising the minimum social media age to 16.

The move is not expected to take effect immediately. The ban is slated for spring 2027, and Liz Kendall said Ofcom has been asked to produce plans for online age verification by October, giving regulators and platforms months to work through the practical details.

Which apps are covered

The headline platforms named so far include Snapchat, TikTok, YouTube, Instagram, X and Facebook. The government has not yet published the full final list, so some of the exact boundaries of the ban remain to be set out in the consultation response expected next month.

Messaging services such as WhatsApp and Signal are reported to be exempt. That distinction suggests ministers are trying to separate social networks built around public feeds and recommendation systems from services used mainly for private communication.

The policy is also broader than a simple social media ban. The government says it will introduce wider restrictions on features such as livestreaming and contact with strangers on some other online services, including gaming platforms.

How enforcement may work

The exact enforcement model is still being worked out. The central issue is how platforms will verify age without creating excessive privacy risks or forcing children and adults through checks that are too easy to game or too intrusive to accept.

Ofcom is expected to set the practical framework for age assurance, but ministers have not yet named a single approved method. That leaves scope for different companies to use different systems depending on how their services collect data and how users access them.

A further challenge is circumvention. The government is expected to address workarounds such as VPN use, but it has not yet published a detailed enforcement plan showing how it intends to stop children from reaching blocked services through other routes.

What changes for older teens and AI chatbots

The plans are not limited to a binary under-16 block. Ministers are still considering what should apply to 16- and 17-year-olds, with current reporting indicating possible default safety settings and limits on features such as late-night scrolling or infinite scrolling.

That suggests the final system may end up tiered: a strict barrier for younger teens, and a separate set of design limits for older adolescents. The government has not yet said exactly how those rules would be written into law or platform policy.

The package also reaches into the fast-growing market for AI companions. Ministers plan an 18-plus age limit for romantic or sexual AI chatbot functions and other intimate chatbot features, extending the policy beyond conventional social media.

Political and industry reaction

Tech companies including Meta, YouTube and Snapchat have already criticised blanket bans. Their argument is that pushing teenagers off mainstream platforms could send them toward less regulated services rather than making them safer.

The government is framing the policy differently, as a child-protection measure rather than an anti-tech move. That argument rests on the view that social platforms can expose children to harmful content, addictive design and contact from strangers.

The political stakes are high because the policy could reshape how major platforms operate in the UK, especially if it requires more intrusive age-assurance systems. It also raises privacy questions about what data companies may need to collect and how much friction users will face.

What happens next

The government is expected to publish the full consultation response next month. That should clarify which services are formally in scope, what exemptions remain and how the new age limits will be framed in practice.

Ofcom is expected to follow with implementation advice on age verification by October. Until then, the biggest unresolved questions are how the ban will be enforced, how VPN circumvention will be handled and what limits will ultimately apply to 16- and 17-year-olds.

For now, the announcement marks a sharp shift in UK online-safety policy. Ministers are moving from broad principles to a rules-based age barrier for some of the country’s biggest digital platforms, while leaving the technical and legal details to be settled over the coming months.
