The UK government says it will ban social media for under-16s, restrict certain high-risk online features for under-18s and strengthen age checks. It expects the first regulations before the end of 2026, with implementation in spring 2027. [1]

A policy has to define its perimeter

A ban is not a single technical switch. The government says it plans to follow a model similar to Australia’s, covering platforms such as Instagram, YouTube, TikTok, Snapchat, Facebook and X, while not intending to include messaging services such as WhatsApp and Signal. [1] AP reported that the proposal has drawn both support and questions about whether a blanket restriction will work. [2]

That makes scope the first test. A rule must explain which services count, which features are restricted, what happens when one product mixes messaging, video and public feeds, and how the rule changes when a user turns 16.

Age assurance is the second test

Age assurance is not the same thing as knowing a person’s complete identity. The policy fact sheet says some adults may not need new checks because of an already-established account or existing age verification; it also mentions options such as facial-recognition checks for over-18s. [1]

The design question is therefore proportionality: collect enough information to apply the restriction, but no more personal data than needed. That is the link between child safety and digital identity. A system that blocks the wrong people, leaks sensitive data or is easy to bypass can weaken trust even if its goal is widely supported.

Enforcement will decide the outcome

TechCrunch reported that experts have questioned whether a blanket ban can be enforced, and the government has acknowledged the challenge. [3] The policy also has to contend with shared devices, false birthdays, new accounts, VPNs and migration to less visible services—problems that cannot be solved by a press release alone.

For readers, the useful question is not simply whether the UK should protect children online. It is whether the final rules can match a clear scope, reliable age assurance, privacy safeguards and accountable enforcement. Those details will determine what the announced ban actually becomes.
