Starmer faces pressure to narrow UK under-16 social media ban to high-risk platforms

Campaigners are urging Keir Starmer's government to abandon a blanket social media ban for users under 16 in favour of a more targeted approach focused on platforms with demonstrably harmful features, warning that sweeping restrictions risk overreach without addressing the root causes of online harm.

The Online Safety Act 2023 gave the media regulator Ofcom the power to require age-verification measures from social media companies serving UK users, with enforcement mechanisms due to come into force over the coming year. The legislation was framed as a landmark step in protecting children from harmful content, but its implementation has generated mounting controversy over whether a one-size-fits-all prohibition is the right tool for the task.

Child safety advocates who have engaged with the government's consultation process argue that the current framework conflates all social media platforms with equal risk, despite evidence that harm profiles vary significantly depending on a platform's design features. The alternative they are pushing — what one coalition described as a "risky features" model — would allow under-16s continued access to platforms without the identified risk factors while blocking those that demonstrably contribute to harm.

The case for targeting specific platform features

Proponents of the narrower approach point to research suggesting that design decisions — algorithmic content amplification, infinite scroll mechanics, push notification frequency, and engagement-maximising recommendation systems — correlate more strongly with adverse outcomes for young users than social media use per se. Under this framing, a platform that hosts moderated community discussion carries a fundamentally different risk profile from one that pushes extreme content through unconstrained recommendation pipelines.

The UK Safer Internet Centre and several affiliated organisations have argued in submissions to Ofcom that a feature-based framework would be more enforceable and more effective than attempting to impose blanket age-verification requirements. Age assurance technology remains imperfect, they note: facial-age estimation systems can be circumvented, and mandatory government ID checks raise separate privacy concerns that the Information Commissioner's Office has flagged as significant.

Research commissioned by the Department for Science, Innovation and Technology in 2024 found that only a minority of adolescents who experienced serious harm online encountered it on platforms without algorithmic content promotion or high-engagement design mechanics. The finding, if reflected in final guidance, would support a narrower regulatory focus.

Criticism of the blanket ban approach

Opponents of sweeping restrictions argue that a blanket ban would be both disproportionate and practically difficult to enforce. Platforms serving UK users already operate in dozens of jurisdictions with varying requirements; enforcing a hard boundary at 16 would require verification infrastructure that does not yet exist at the necessary scale or reliability.

The Open Rights Group, which submitted evidence to the Online Safety Act implementation consultation, warned that age-verification requirements could create surveillance infrastructure with implications far beyond their intended scope. Requiring users to submit identity documents to access legal adult content — or social platforms broadly — normalises data collection that threat actors could exploit.

There is also a concern that a strict prohibition, rather than removing harm, simply displaces it: teenagers denied access to mainstream platforms may migrate to lesser-moderated spaces where the very risks the legislation aimed to address are more acute. Several campaign groups have drawn parallels with prohibition-era dynamics in other policy domains.

Implementation challenges and regulatory tension

Ofcom has published draft guidance on how platforms should comply with the age-assurance requirements, but the guidance has been criticised by both industry and advocacy groups — for different reasons. Tech companies argue the requirements are technically undeliverable within the proposed timelines without compromising functionality. Child safety campaigners argue the guidance is too permissive in what it counts as sufficient compliance.

The regulator is expected to publish revised guidance following the consultation period, but it faces a structurally difficult task: balancing the government's political commitment to demonstrable action on child safety with technical constraints that make airtight age verification near-impossible without invasive data collection.

Several major platforms — including Snapchat, TikTok, and Instagram — have engaged with the consultation process, proposing self-regulatory measures including default private accounts for under-18 users, content restriction systems calibrated by age, and parental supervision tools. These proposals have drawn scepticism from groups who note that the same platforms have previously failed to honour voluntary commitments on child safety.

What the government faces ahead

The Online Safety Act was a flagship initiative of the previous Conservative government, but Starmer's administration has broadly endorsed its framework while signalling it may revise implementation timelines and guidance. The pressure from campaigners represents a challenge to the binary choice between a comprehensive ban and voluntary industry measures.

Whether the government moves to carve out a feature-based exemption — effectively creating a two-tier system for social media regulation — will depend on whether ministers believe the political optics of protecting children justify the technical complexity. Child safety groups have made clear they view the current trajectory as insufficient; platforms that have engaged constructively with Ofcom are watching for signals about what compliance looks like in practice.

The outcome will shape how Ofcom exercises its new powers and how platforms worldwide structure their age-gating systems. For teenagers who have grown up with social media as a default environment — for social connection, for educational resources, for civic participation — the scope of the restrictions will determine which kind of internet they encounter as they cross into adulthood.

This publication approached the story with emphasis on the implementation critique from child safety advocates rather than the government's framing of the legislation as a landmark protection measure.
