Kendall sets UK overnight social-media curfew for older teens

Britain's new set of default protections for 16 and 17-year-olds is more interesting for what it opts against than for what it opts in. Technology Secretary Liz Kendall's announcement, reported by Reuters and picked up widely across UK press, sets a default overnight social media curfew from midnight to 6am, switches off infinite scroll and algorithmic feeds, and forces regular break reminders on under-18s using AI chatbots. Critically, older teenagers will be able to switch these default settings off.

That 'default on, opt-out' design is doing most of the work. The UK is not banning anything at 16 or 17; it is nudging the platform architecture in a direction that assumes rest and disengagement rather than attention capture. Kendall's framing, that 'even as young people gain greater independence at 16, they should still be protected from the most addictive online features that can have a harmful impact on their wellbeing,' positions this as design regulation of the products themselves rather than a rights restriction on the teens.

The chatbot piece is the part product teams should read carefully. Alongside break reminders for under-18s, the government is targeting AI services that offer 'dangerous, misleading or unverified mental health advice,' with ministers reportedly considering banning chatbots that pose a serious threat to children. If you ship a general-purpose assistant in the UK, 'the user asked' is not going to be a defense for mental-health-adjacent outputs to minors.

The honest caveat is the one critics have already raised: opt-out defaults are trivially defeated by the very demographic they target, and the evidence base cited is a government pilot involving 'more than 300 teenagers and parents' across the UK, which is thin for a nationwide design mandate. What the reporting does not give you is a firm start date, an enforcement mechanism, or which specific platforms and chatbot providers fall in scope.

The forward-looking piece is who benefits from writing the compliance playbook first. Whichever major platform or chatbot provider ships credible default-safe UK teen modes before the statutory detail lands is likely to shape what 'reasonable' ends up meaning when the harder rules arrive.
