The Department for Science, Innovation and Technology said on 15 June that social-media platforms would be blocked from offering services to under-16s. The government said legislation was expected before Christmas and that protections were expected to come into force in spring 2027.
That timetable turns a broad child-safety pledge into a delivery test for ministers. By spring 2027, the public will be able to judge not only whether a law exists, but whether the system can distinguish children from adults without creating excessive data risks.
The plan goes beyond a headline ban. A government fact sheet said certain harmful features on other online services, including livestreaming and contact from strangers, would be restricted for under-18s. It also said 16- and 17-year-olds would receive default protections, while platforms would be expected to use rigorous age checks.
That makes Ofcom central, because the communications regulator already enforces the Online Safety Act framework and would have to translate ministerial policy into rules platforms can follow. The Guardian reported that Technology Secretary Liz Kendall wanted Ofcom to design age-verification plans by October and report annually to parliament on how effectively platforms keep under-16s off their services.
The consultation gives ministers a political mandate but not an implementation manual. The government said 9 in 10 parents backed a social-media ban for under-16s and that two-thirds of young people agreed under-16s should not be allowed to use at least some social-media platforms. Those figures explain why ministers are willing to legislate. They do not answer how age checks should work without collecting too much personal data or pushing teenagers to less visible services.
The platform response is the main practical counterweight. The Guardian reported that Meta, YouTube and Snapchat criticised the proposal, warning that a ban could drive young people toward less regulated online spaces. That argument should not be accepted as neutral public-interest analysis from companies whose services would be restricted. It is still a real implementation risk: a ban that moves teenagers from mainstream platforms to smaller or offshore services could weaken oversight.
