UK Social Media Ban for Under-16s: Start Date and Affected Apps
The UK is preparing one of the most far-reaching online safety reforms in the world. On 15 June 2026, Prime Minister Sir Keir Starmer confirmed that children under the age of 16 will be banned from using major social media platforms, describing the move as “a line in the sand” for future generations. The announcement has sparked an immediate wave of questions from parents, teenagers, schools, advertisers and the tech companies themselves.
If you are trying to work out exactly when the UK social media ban for under-16s starts, which apps are affected, and what it means for your family, this guide breaks down everything confirmed so far.
What has the UK government announced?
The government has confirmed plans to block social media platforms from offering their services to anyone under the age of 16 in the UK. The policy was unveiled by the Prime Minister alongside Technology Secretary Liz Kendall, and it forms the centrepiece of a wider crackdown on online harms aimed at protecting children’s mental health, curbing addictive platform design and reducing excessive screen time.
Crucially, the UK plans to go further than a simple blanket ban. Alongside the age restriction, ministers intend to introduce additional “world-leading” controls on high-risk features such as livestreaming and the ability of strangers to contact children. These functionality restrictions will apply to a broader range of online services beyond traditional social media, including gaming platforms.
The government says the package is designed to respond to how children experience harm online, not just where it happens. In the words of the Prime Minister, tech giants “had their chance and failed,” and the state is now stepping in to put decision-making power back into parents’ hands.
When does the UK social media ban for under-16s start?
This is the question on most people’s minds, so here is the clearest answer available.
The ban is expected to come into force in Spring 2027. The government plans to bring the necessary regulations before Parliament before Christmas 2026, with the first set of protections taking effect the following spring.
The timeline is realistic because ministers have already secured the legal powers they need through the Children’s Wellbeing and Schools Act 2026. This allows the government to introduce targeted protections using secondary legislation, rather than having to draft and pass an entirely new Act from scratch — a process that would have taken considerably longer.
Importantly, nothing changes overnight. For now, under-16s can continue using social media platforms as normal while the legislation and enforcement framework are finalised. The June 2026 announcement confirms the direction of policy, but several practical details — including exact implementation dates, compliance requirements and penalties — are still to be published in the coming weeks and months.
A short summary of the timeline:
- 15 June 2026 — Government confirms the under-16 social media ban
- July 2026 — Further detail expected on AI chatbots, overnight curfews and infinite-scroll limits
- Before Christmas 2026 — Regulations expected to be brought to Parliament
- Spring 2027 — First protections expected to come into force
Which apps are affected by the ban?
The government intends to mirror the model used by Australia, which introduced the world’s first under-16 social media ban in December 2025. The rules will capture user-to-user platforms whose core purpose is social interaction, that allow people to post material, and that use algorithms to serve content.
The government has officially named the following platforms as being caught by the ban:
- TikTok
- Snapchat
- YouTube
- X (formerly Twitter)
Following the Australian template, reporting suggests the final list is also likely to include other major content-sharing and social platforms such as Reddit, Twitch, Threads and Kick. Ministers are expected to confirm the complete, definitive list of affected apps in the coming weeks, so families should treat the current list as indicative rather than final.
The common thread is clear: if a platform is built around algorithmic feeds, social posting and user-to-user interaction, it is very likely to fall within scope.
Which apps are NOT affected?
Not every app a teenager uses will be swept up by the ban. The government has indicated that private messaging services are not the target of this particular policy.
At present, the following are not expected to be included:
- Signal
The reasoning is that these are messaging services rather than algorithm-driven social media platforms. The government’s focus is squarely on content-sharing and social networking apps where real-time content is harder to moderate and where recommendation algorithms can intensify a child’s exposure to distressing, dangerous or excessively engaging material.
That said, ministers have made clear that broader online safety measures are still being developed, so the boundaries could shift as the detailed regulations are drafted.
Beyond the ban: extra restrictions on features and AI chatbots
One of the most significant aspects of the UK’s approach is that it does not stop at an age limit. The government plans a series of additional protections that, taken together, it says go further than any other country.
Livestreaming and stranger contact. Under-16s will face blocks on high-risk functions such as livestreaming and the ability of strangers to communicate with them. These restrictions will extend beyond social media to a wider range of online services, including gaming sites.
Preventing a “cliff-edge” at 16. To avoid a sudden jump in risk the moment a teenager turns 16, several of these functionality restrictions will be switched on by default for 16- and 17-year-olds, who can presumably adjust them as older teens.
AI “romantic companion” chatbots. AI chatbots designed to simulate sexual relationships or romantic roleplay will be required to enforce a minimum age of 18. Similar intimate functionalities will be restricted for under-18s on AI chatbots more broadly — a notable acknowledgement of how quickly generative AI tools have entered young people’s online lives.
Curfews and infinite scroll. The government is also examining overnight curfews and “breaks” in infinite scrolling for under-18s. More detail on these measures is expected in July 2026.
How will the under-16 ban be enforced?
A key principle underpinning the policy is that responsibility will sit with the platforms, not with children or their parents. Companies — rather than individual users — will face penalties for failing to comply.
This mirrors the Australian system, which requires platforms to take “reasonable steps” to verify users’ ages and prevent underage access. To make this work, the government wants to introduce what it calls “highly effective age assurance” (HEAA) to make it far harder for children to bypass the rules.
A range of age-verification technologies could be used, including:
- Government-issued ID checks
- Facial age estimation
- Voice recognition
- Behaviour-based age inference tools
- Other age-assurance technology
To get the detail right, the regulator Ofcom has been asked to carry out a rapid study into what counts as effective age assurance for confirming whether a user is over 16. The Technology Secretary has also written to Ofcom’s new Chair requesting an urgent review of the regulator’s enforcement capabilities, with a clear enforcement strategy to follow. The government has pledged to ensure Ofcom has the funding required to take on these new responsibilities, on top of its existing work enforcing the Online Safety Act.
Will existing accounts be deleted?
This is one of the areas where details are still pending. The government has not yet confirmed how existing accounts held by under-16s will be treated.
For reference, Australia’s approach requires platforms both to prevent children from creating new accounts and to deactivate existing accounts belonging to under-16s. Whether the UK follows exactly the same path remains to be confirmed in the forthcoming regulations.
Why is the government introducing the ban?
The decision follows one of the largest public consultations the government has run on the issue, attracting more than 116,000 responses from parents, children and experts. The findings revealed strong public appetite for tougher action:
- Around 9 in 10 parents said they would support a social media ban for children under 16.
- A reported 85% said the risks of social media outweigh the benefits.
- Roughly two-thirds of young people agreed that under-16s should not be allowed to use at least some social media platforms.
The government argues that real-time content makes harmful material harder to moderate, while algorithmic feeds can amplify exposure to dangerous or distressing content. The announcement also builds on a separate challenge to tech firms to make it impossible for children to take, share or view nude images, alongside investment in after-school clubs and enrichment activities intended to give children alternatives to screen time.
Is everyone in favour?
Not entirely. While public support is high, some campaigners and researchers have raised concerns. Human rights groups have argued that the core problem is platform design rather than children’s mere presence online, suggesting that regulating manipulative features — profiling, autoplay, infinite scroll and hyper-personalised recommendations — may be more effective than excluding young people altogether.
Critics also warn of unintended consequences, such as pushing children towards less-regulated corners of the internet, or limiting the ability of marginalised young people to find supportive online communities. Public health experts have broadly welcomed action while stressing that implementation and evidence-gathering will be critical. These debates are likely to intensify as the detailed regulations take shape.
What does this mean for parents and teenagers?
In the short term, very little changes. Until the regulations take effect in Spring 2027, under-16s can keep using their existing accounts.
Looking ahead, parents may want to:
- Stay informed about the final list of affected apps, due to be confirmed by ministers.
- Talk to children early about the upcoming changes so the transition is less jarring.
- Explore alternatives for the parts of social media teenagers value, such as staying connected with friends through messaging apps that fall outside the ban.
- Watch for the July 2026 update, which should clarify rules on AI chatbots, curfews and scrolling limits.
