The United Kingdom (UK) has unveiled plans for one of the world’s most extensive restrictions on children’s online activity, proposing to prohibit those under the age of 16 from accessing major social media platforms while also limiting their use of certain gaming and artificial intelligence services.
Prime Minister Keir Starmer announced the proposed measures on Monday, arguing that the government must act to protect children from online content and features that are designed to be addictive and potentially harmful to their mental well-being.
Under the proposal, children younger than 16 would be barred from creating or maintaining accounts on platforms including TikTok, Instagram, Facebook, Snapchat, YouTube and X.
The restrictions would extend beyond traditional social media. Starmer said the government also intends to block under-16s from accessing features such as livestreaming and direct communication with strangers online. Certain gaming platforms would also be brought under the proposed framework.
The government has also announced plans to prohibit individuals under 18 from using artificial intelligence “romantic companions,” though details on how that restriction would be implemented have not yet been disclosed.
What Would Still Be Allowed?
Despite the proposed crackdown, not all online communication tools would be off limits.
Messaging services such as WhatsApp would remain accessible to children under 16, according to the government’s outline. The distinction reflects an effort to separate private communication services from platforms driven by public feeds, recommendation algorithms and engagement-based content.
The legislation would place responsibility on technology companies to verify users’ ages and prevent underage access. Companies that fail to comply could face substantial financial penalties.
The government hopes to secure parliamentary approval by the end of this year, allowing the restrictions to take effect by the spring of 2027.
Following Australia’s Lead
The U.K. move follows similar action in Australia, which became the first country to enact a nationwide ban on social media access for under-16s in December 2025.
However, Australia’s experience has highlighted enforcement challenges. A survey conducted by the country’s internet regulator earlier this year found that about 70 percent of parents believed their children were still accessing social media platforms by bypassing age-verification systems.
Starmer acknowledged those challenges but argued they should not deter governments from acting.
Growing International Momentum
The British proposal comes as governments around the world grapple with concerns about the impact of social media on young people.
Countries including France, Denmark, Malaysia and Ireland are considering or developing measures aimed at limiting children’s exposure to social media platforms.
The debate has intensified amid growing research linking excessive social media use among adolescents to increased rates of anxiety, depression, sleep disturbances, cyberbullying, body-image concerns and reduced attention spans. Mental health experts have also raised concerns about algorithm-driven content feeds, endless scrolling features and notification systems designed to maximize user engagement.
At the same time, researchers caution that the relationship between social media and mental health is complex. Some studies have found only modest links between social media use and psychological harm, suggesting that factors such as the type of content consumed, time spent online and individual circumstances play an important role.
Advocates of digital access also point to the benefits of social media, including educational opportunities, creative expression, peer support networks and social connections, particularly for young people who may feel isolated in their communities.
Critics of outright bans question whether age-verification systems can be effectively enforced and warn that restrictions could push children toward less regulated online spaces. The U.S. Embassy in London recently voiced concerns about the proposed British restrictions, arguing that age-gating technologies may not be effective and emphasizing that parents remain the primary line of defense in protecting children online while preserving freedom of expression.
Community Efforts Offer an Alternative
Even before governments began pursuing nationwide restrictions, some communities were experimenting with their own solutions.
In the Irish coastal town of Greystones, parents, schools and community leaders launched a voluntary initiative encouraging families to delay giving smartphones to children until secondary school. Educators involved in the effort reported concerns about rising anxiety levels among students following the COVID-19 pandemic and sought to reduce children’s exposure to social media while promoting alternative activities and digital literacy.
Supporters say the initiative has led to improved classroom focus, better sleep habits and increased face-to-face interaction among students, although participation remains voluntary rather than legally mandated.
The United Kingdom’s proposal could become a major test case for governments seeking to address concerns about children’s online safety. Supporters argue that stronger regulation is necessary to combat online addiction, cyberbullying, harmful content and the growing mental health challenges facing young people.
Some researchers and policy analysts contend that bans alone are unlikely to solve those problems and caution that effective solutions must also include parental involvement, digital literacy education and greater accountability from technology companies. The success or failure of Britain’s approach is likely to influence similar policy discussions already underway in countries around the world.
