On 15 June 2026 the Prime Minister, Keir Starmer, announced that the UK government would introduce a social media minimum age of 16, backed by "highly effective" age assurance and enforced by Ofcom under the Online Safety Act 2023. Regulations are expected before Parliament by the end of 2026, with protections expected to come into force in spring 2027.
As of 29 September 2026, the restrictions themselves are not yet in force. Parliament has required the government to act, but the regulations that put them into effect, the final list of platforms and the compliance deadlines are still being finalised. That matters because what changes for a Year 9 student's daily phone use depends on those specifics.
This piece walks through what has been announced, what is still open, and what parents, students and schools can sensibly do now.
Status as of 29 September 2026: Parliament has already required the government to bring in an under-16 restriction (through the Children's Wellbeing and Schools Act 2026), but the regulations that set out how it works have not yet been laid or approved, so nothing has changed for users yet. The specific commencement date, exempted services list, and enforcement thresholds are still being drafted. Everything below is what has been proposed, not settled law.
What was announced on 15 June 2026
The 15 June 2026 announcement set out a plan for a minimum age of 16 to hold an account on major social media platforms in the UK. Six platforms were named at the announcement: Facebook, Instagram, TikTok, Snapchat, YouTube, and X (formerly Twitter). The stated mechanism is age assurance, meaning platforms will need to verify users are over 16 using "highly effective" methods; Ofcom is assessing which methods work for over-16 checks.
The announcement also said under-16s would be blocked from livestreaming and from being contacted by strangers across platforms, including gaming sites.
Messaging services, including WhatsApp and Signal, were not included in the announcement. Those apps continue to operate under existing Online Safety Act rules, which apply their own duties around illegal content and safety by design without an age gate at 16.
Government framed the ban as protecting children's wellbeing and childhood; it did not publish a target for outcomes, so anyone claiming the ban "will cut teen anxiety by X percent" is guessing.
Which platforms are covered, and which aren't
| Service | Named in announcement? | Notes |
|---|---|---|
| Yes | Meta's main social platform | |
| Yes | Meta, covered separately from Facebook | |
| TikTok | Yes | Short-form video |
| Snapchat | Yes | Camera-first messaging + Stories |
| YouTube | Yes | Includes YouTube accounts; passive viewing rules to be clarified |
| X (Twitter) | Yes | Named in the 15 June 2026 announcement |
| No | Messaging service, not covered | |
| Signal | No | Messaging service, not covered |
| iMessage / SMS | No | Not covered |
| Discord, Reddit, Twitch | Not confirmed | Announcement did not specifically name; scope to be set by regulations |
One detail worth calling out: the announcement did not mention any parental consent route, and the regulations will confirm whether there is one.
When the ban comes into force
The government's stated timeline is regulations before Parliament by the end of 2026, with protections expected to come into force in spring 2027. That is an ambition, not a specific commencement date. The government has asked Ofcom, the regulator that will enforce age assurance under the Online Safety Act 2023, to report by the end of October 2026 on which age assurance methods can reliably check whether a user is over 16. That report will shape the regulations.
Until the regulations are laid, no platform is legally required to remove under-16 accounts, and no student is doing anything unlawful by holding one. If you are reading this in autumn 2026, treat the ban as a signalled policy change rather than an active rule.

How age verification is likely to work
Ofcom's "highly effective age assurance" framework, which already applies to adult content services under the Online Safety Act, sets a standard that a self-declared date of birth is not enough. Methods that meet the threshold typically include photo ID checks, credit card verification, facial age estimation (using AI to estimate age from a selfie), and open banking-based checks.
How platforms implement this at the scale of a TikTok or an Instagram is the open question. Facial age estimation is currently the most-discussed approach because it does not require handing over a passport, but it has known accuracy variance across age bands and demographic groups. Ofcom's assessment (due by the end of October 2026) and the regulations are where acceptable methods get pinned down.
What this could change day-to-day for students
Even in the version of the policy that ministers have described, quite a lot of what students use platforms for at school-age still works. A few worth thinking through:
Messaging in group chats mostly moves to WhatsApp and iMessage, which are not covered. That is where a lot of school year-group chat already lives, so this may not feel like a big shift.
Watching YouTube revision videos without a logged-in account is a grey area in the announcement. Passive viewing of YouTube content is technically different from holding an account, and the regulations will need to clarify whether age-gated logged-in access is required for all YouTube use.
TikTok study creators and Instagram revision accounts would be inaccessible to under-16 account holders. If your GCSE revision routine leans on a specific TikTok creator, that habit changes. Cognito's own GCSE Combined Science course for AQA Higher is a self-contained option that sits outside social platforms.
Group study coordination that currently happens via Instagram DMs would need to move. That is a habit shift more than a content one.
Mental health and wellbeing effects are the reason ministers gave for the policy in the first place, but the causal picture on teen mental health and social media is contested in the academic literature. We would avoid strong claims about outcomes until there is UK-specific evidence post-implementation. Our back-to-school anxiety guide covers the well-supported ground on revision-season wellbeing without leaning on the ban's stated benefits.
How the UK approach compares to Australia's
The Australian precedent is the one to know, because it is the longest-running under-16 ban. France has also passed an under-15 ban, due to be phased in from September 2026 and January 2027, subject to review by France's Constitutional Council. Australia's Online Safety Amendment (Social Media Minimum Age) Act 2024 was passed on 29 November 2024 and took effect on 10 December 2025. The Australian eSafety Commissioner enforces it, and the covered platforms include Facebook, Instagram, Reddit, Snapchat, TikTok, X, Threads, Twitch, Kick, and YouTube.
Two things worth noting from the Australian rollout. First, the covered list is broader than the UK's June 2026 announcement, particularly for Reddit, Threads, Twitch and Kick. The UK regulations may or may not follow suit. Second, the Australian model does not include a parental consent route; the UK announcement did not address the question. If your household relies on Australian polling numbers or early Australian enforcement data, remember the samples and the app mix are not directly comparable.
What parents and schools can do now
- Have a household conversation about which apps your child uses and why, so the shift (if it happens) is not a surprise
- Check school policies on phone use and app-based homework, since some depend on Instagram or TikTok in ways that may need rethinking
- Watch for Ofcom's report on age checks for under-16s, due by the end of October 2026
- Follow the gov.uk Online Safety Act collection page for regulations as they are laid
- Talk to your school's safeguarding lead if you want to know how they plan to adjust digital citizenship teaching
- If revision routines rely on social platforms, have a backup that sits outside them (revision websites, textbooks, structured courses)
None of these are urgent yet. The ban is not in force, and there is no penalty for continuing existing use while the regulations are drafted. What we would avoid is over-reacting to headlines before the specifics are set. Our how to revise effectively guide is a better use of a Year 10's attention this term than pre-emptively deleting apps.
