The UK is launching a real-world experiment to claw back childhood from the grip of social media, testing outright bans, strict daily time limits, and overnight digital curfews on hundreds of teenagers across the country.
Announced on Wednesday (25 March), the six-week pilot will involve 300 families with teenagers aged 13 to 17.
Participants will be divided into four groups: one facing a full home ban on selected social media apps via parental controls; another limited to just one hour per day on platforms like Instagram, TikTok, and Snapchat; a third subject to a “digital curfew” blocking access between 9 pm and 7 am; and a control group with no changes.
The goal is to gather hard evidence on how these restrictions affect sleep, family interactions, school performance, and overall well-being – data that will feed into a broader national consultation on children’s digital safety.
“We are determined to give young people the childhood they deserve and to prepare them for the future,” said Technology Secretary Liz Kendall.
“This is why we are listening to parents, children and experts with our consultation, as well as testing different options in the real world. These pilots will give us the evidence we need to take the next steps, informed by the experiences of families themselves.”
The trial comes amid growing alarm over social media’s impact on youth mental health, including links to anxiety, sleep disruption, bullying, and exposure to harmful content.
It runs in parallel with the “Growing up in the online world” consultation, which has already drawn nearly 30,000 responses from parents and children and remains open until 26 May.
A separate, larger scientific trial funded by the Wellcome Trust, involving 4,000 students aged 12-15 in Bradford schools, will examine broader effects on anxiety, body image, school absences, and more.
Families in the pilot will be interviewed before and after the six weeks to capture practical realities: How easy (or hard) is it to enforce controls? Do teens find workarounds? Does family life improve when the scroll stops after dinner?
Professor Amy Orben, a University of Cambridge psychologist co-leading the Bradford trial, highlighted the evidence gap when it comes to making policy decisions around social media.
“We currently lack critical insights about how different types of social media policies might work in practice. Large randomised controlled trials will allow us to both better understand the impact of social media and select interventions that work for young people as well as their families,” she said.
The move builds on the UK’s existing Online Safety Act but signals a willingness to go further, potentially toward mandatory age restrictions or platform design changes.
It echoes debates in Australia, which has pursued an under-16 ban, and in the US and Europe, where lawmakers grapple with addictive algorithms versus free expression and practical enforcement challenges.
