July 15 (UPI) — Britain announced plans Wednesday for a midnight social media curfew for older teens aimed at preventing them from staying up late into the night on apps such as Instagram, TikTok and YouTube, with the new measures expected to take effect in Spring 2027.

Targeted at 16- and 17-year-olds and following on from a full social media ban for children younger than 16 announced in June, the package of measures calls for a 12 a.m. to 6 a.m. curfew to be set by default within the apps and that other “addictive features” such as autoplay and customized feeds be automatically disabled, the government said in a news release.

However, unlike the total ban for under-16s, restrictions on the older teens will be discretionary, meaning they will be able to override them, or turn features back on again, at will.

The Science, Technology and Innovation Department said the move was designed to ease young people’s transition into the online world and ensure there was “no cliff edge” when the full social media restrictions they will have been under, in some cases for their entire life, were suddenly lifted when they turn 16.

It said the protections, which came out of a nationwide pilot that found they improved sleep and focus, struck a balance between protecting older teenagers while giving them age-appropriate independence to change the settings, trusting that they will make good choices.

“Our consultation provided a clear message from parents and teenagers alike — 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,” said Technology Secretary Liz Kendall.

“These measures will be crucial in helping young people get the sleep they need, focus on school and college, and spend more quality time with family and friends, all of which are fundamental to building a happy, healthy and fulfilling adult life,” she added.

The first set of regulations will be introduced to parliament by the end of this year, with measures expected to come into force in spring 2027, timed to coincide with when the social media ban for children younger than 16 comes into force.

The opposition Conservative Party’s shadow education secretary Laura Trott described the move as “absurd.”

“Either Labour think 16 & 17 year olds should be on social media or they don’t, but curfews they can switch off won’t achieve anything. They should stop tinkering and get on with getting u16s off social media,” she wrote in a post on X.

Ellen Roome, who alleges her 14-year-old son lost his life in an online dare that went awry in 2022, was also highly critical.

“I just think it’s not good enough really just to have a product you can switch off; it’s a bit like offering a 17-year-old a bottle of alcohol and then moving it slightly out of arm’s reach, they can just drag it back in, I really wish they could go stronger and harder on these things,” she told the BBC.

Kendall said measures were also in the pipeline to help children younger than 18 use AI chatbots safely, including regular breaks, and tackling bots or apps pushing “dangerous, misleading or unverified” mental health tips with ministers open to all solutions, including banning chatbots that put children at serious risk.

Wednesday’s development follows announcements in June giving Apple, Google and other tech firms three months to stop explicit images from being shot, shared or viewed on children’s mobile phones and in April on planned legislation to ban children from using smartphones in schools in England.
