The UK government has unveiled plans to introduce a default overnight social media curfew for 16- and 17-year-olds as part of a broader effort to strengthen online safety and encourage healthier digital habits among young people. The proposal forms part of the government's wider strategy to reduce excessive screen time and limit exposure to features designed to keep users engaged for extended periods.

Under the proposal, social media platforms would automatically restrict access for affected users between midnight and 6 a.m. by default. Teenagers would still be able to change these settings themselves, but the government believes default protections will encourage better sleep, improved concentration, and healthier online behaviour.

In addition to the overnight curfew, platforms would be required to disable certain "addictive" features by default for older teenagers. These include functions such as infinite scrolling, autoplay videos, and continuously personalised content feeds that encourage prolonged use. Officials say the measures are intended to create a safer digital environment while allowing older teens to retain greater independence online.

The announcement follows earlier proposals to restrict social media access for children under the age of 16. Government officials argue the new rules will ensure that protections continue as young people move into later adolescence rather than ending abruptly when they turn 16. The initiative also includes plans to strengthen media literacy education in schools, with greater emphasis on artificial intelligence, misinformation, and responsible digital citizenship.

While many parents and child safety advocates have welcomed stronger safeguards, the proposals have also prompted debate over their effectiveness. Some critics argue that teenagers may simply opt out of the default settings, while others have raised concerns about implementation and enforcement. Despite differing opinions, the government maintains that the policy strikes a balance between protecting young people and preserving personal choice.

The proposed regulations are expected to be introduced in Parliament later this year, with implementation planned for 2027 if approved. Technology companies will be required to comply with the new standards as part of the UK's evolving online safety framework.
