The proposals come amid growing concerns about the impact of social media on young people's mental health, sleep patterns, safety, and overall development. Government officials are currently evaluating a range of options, including age-based bans, screen-time limits, overnight curfews, and restrictions on platform features designed to encourage prolonged engagement.
Growing Pressure for Action
Calls for stronger regulation have intensified in recent years, driven by bereaved families, health experts, campaign groups, and lawmakers who argue that existing safeguards are insufficient.
The issue gained further momentum after Prime Minister Keir Starmer met with parents whose children died after being exposed to harmful online content. Campaigners have long accused social media companies of failing to adequately protect young users, while ministers have signaled their willingness to take decisive action following extensive public consultations involving tens of thousands of participants.
If implemented, the measures would place the United Kingdom alongside Australia, which recently introduced a landmark law preventing children under 16 from accessing most social media platforms.
UK officials are examining mechanisms such as age verification systems, app usage restrictions, and mandatory safety standards aimed at reducing risks for children online.
What Does the Science Say?
At the center of the debate is a growing body of research suggesting that excessive social media use may pose significant risks to children's physical and mental well-being.
The Academy of Medical Royal Colleges has described social media as an emerging public health concern, citing evidence linking heavy usage to anxiety, depression, poor sleep quality, cyberbullying, exposure to self-harm content, and participation in dangerous viral challenges.
Numerous studies have found associations between extensive social media use and increased rates of depression, anxiety, loneliness, self-harm, and suicidal thoughts among adolescents. Research has also identified a relationship between constant smartphone engagement and rising levels of psychological distress.
Several reviews suggest a "dose-response" effect, meaning the risks tend to increase as screen time rises. One study found that children spending more than three hours per day on social media were significantly more likely to experience symptoms of anxiety and depression, with sleep disruption identified as a major contributing factor.
Sleep has emerged as a key concern for policymakers. Researchers have found that social media use can delay bedtime, reduce sleep quality, and contribute to irregular sleep schedules. Studies also indicate that children spending four or more hours per day on screens are more likely to experience anxiety, depression, behavioral difficulties, and attention-related problems.
Experts further note that adolescence is a critical developmental period during which self-esteem, emotional regulation, and impulse control are still forming. Excessive social media exposure may interfere with these processes.
However, the scientific picture remains complex. Some researchers argue that the nature of online experiences may matter more than the amount of time spent online. A large study involving approximately 25,000 young people found no clear evidence that social media use alone directly causes worsening mental health outcomes. Instead, factors such as cyberbullying, harmful content, social comparison, and algorithm-driven pressures may play a more significant role.
Potential Measures Under Consideration
While ministers have not finalized any proposals, Technology Secretary Liz Kendall has suggested that stronger restrictions on platforms such as TikTok, Instagram, and Snapchat remain under active consideration.
According to government figures, nearly 90 percent of parents who responded to the Online Safety consultation supported stricter age limits, similar to those introduced in Australia.
Speaking to the Sunday Mirror, Kendall said parents are increasingly worried about issues such as excessive scrolling, late-night phone use, and peer pressure, while recognizing that social media also offers benefits.
More than 100,000 people participated in the consultation process, including approximately 40,000 parents. The government is expected to review the findings before making a final decision in the coming weeks.
Kendall confirmed that a ban for under-16s remains "on the table," emphasizing that parents are seeking measures that deliver meaningful protection for children.
She acknowledged that young people may attempt to bypass restrictions, comparing the challenge to age limits on smoking and alcohol. Nevertheless, she argued that this does not diminish the need for clear rules and stronger enforcement.
In addition to age verification requirements, the government is exploring educational initiatives to help children navigate online environments more safely and critically assess digital information.
The consultation also examined issues such as AI chatbot age restrictions, stranger-matching features in online games, live-streaming controls, and overnight usage curfews.
Holding Tech Companies Accountable
The government has made clear that social media companies will be expected to comply with tougher safety standards.
Kendall stated that platforms must prevent illegal content from reaching users and ensure harmful material is not accessible to children. She stressed that technology companies would face consequences if they fail to meet legal obligations.
The Technology Secretary also defended the UK's Online Safety Act, arguing that weakening the legislation would undermine years of work aimed at improving online protections.
At the same time, she emphasized that technology and artificial intelligence can deliver significant benefits, including advances in healthcare and disease diagnosis. However, she maintained that public trust depends on ensuring that these technologies are safe, particularly for children.
What Happens Next?
The government appears to be pursuing a middle-ground approach that combines stronger age verification, limits on addictive features such as infinite scrolling and autoplay, overnight curfews, daily usage caps, and stricter enforcement against non-compliant platforms.
Whether ministers ultimately choose an outright ban for under-16s or a package of targeted restrictions, one thing is clear: the political conversation around children's social media use has shifted dramatically, and the UK is preparing to take a far more interventionist approach to online safety.
