UK To Bar Under-16s From Mainstream Social Media From Early 2027 — What Will Change

The UK government has announced plans to ban children under 16 from mainstream social media platforms, with rules due to take effect in early 2027. Ministers say the move aims to reduce online harms to children, while also introducing new default restrictions on the riskiest platform features for older teens.

Which Platforms Will Be Affected?

The government specifically named major apps such as Snapchat, TikTok, Instagram, Facebook and X. YouTube will be included in the ban for under-16s, although YouTube Kids — the child-friendly version of the service — will remain available. A full list has not been published, but officials say the rules will apply to services "whose purpose is to enable social interaction and which allow users to post material." Messaging-only services such as WhatsApp and Signal are not intended to be included.

Feature-Level Restrictions

Rather than banning every platform used by children, the government plans to target high-risk features. Livestreaming and the ability for strangers to contact users will be switched off by default for under-17s — a measure designed to avoid a sudden change at age 16. For gaming sites such as Roblox, the platforms themselves may remain accessible but specific features (for example, chat) could be restricted.

Additional Safeguards Under Consideration

Officials are also exploring further protections for under-18s, including an overnight curfew and breaks or pauses to disrupt endless, algorithm-driven scrolling. Ministers said more detail on these measures would be published in July.

AI, Age Checks and Enforcement

The government wants "highly effective age assurance" to prevent under-16s from using covered services. That could include biometric face-scans or requests for identity documents. Ofcom has been asked to run a rapid study to identify the most reliable verification methods. AI chatbots marketed as "romantic companions" will need to verify users are 18 or over, and broader AI systems must disable or restrict intimate functions for under-18s.

Practical concerns: Regulators and campaigners highlight privacy risks from sharing ID data and warn that workarounds such as VPNs could undermine enforcement.

Timing and Political Context

Ministers aim to lay regulations before Christmas, creating a legal framework that would allow implementation by spring 2027. The proposal follows a public consultation that attracted more than 116,000 responses and echoes a model introduced in Australia in December 2025.

Reactions

Bereaved parents and online-safety campaigners welcomed the announcement. Some tech companies — including YouTube and Meta (owner of Facebook and Instagram) — warned a blanket ban could push teens toward less regulated services and suggested device-level age verification instead of asking users to provide ID to many separate apps. Teenagers have expressed concerns that a ban could limit social connection and self-expression.

International Picture and Implementation Challenges

The Organisation for Economic Co-operation and Development notes about 25 countries have age-based social media restrictions under consideration or in force. Australia's rollout has encountered enforcement problems: many young users remained active and regulators have been slow to issue fines. Officials in the UK say they will take those lessons into account when designing enforcement mechanisms.

For parents and caregivers, regulators and charities provide guidance on keeping children safe online; the government and Ofcom have promised further detail on enforcement and technical approaches in coming months.
