Ofcom Launches Formal Investigation into TikTok’s Child Protection Measures

The UK’s communications regulator, Ofcom, has opened a formal investigation into TikTok to determine if the platform is failing to adequately protect children, as required under the UK’s Online Safety Act. The regulator is scrutinizing whether TikTok’s age-assurance technologies are sufficient to prevent minors from accessing harmful content, including material depicting self-harm, eating disorders, and pornography. If found in breach of the law, TikTok faces potential fines of up to £18 million or 10% of its global annual turnover, whichever is greater, alongside the possibility of restricted access within the UK.

Regulatory Scrutiny of Age-Assurance Technology

Ofcom’s investigation centers on the efficacy of the age-estimation methods currently employed by TikTok. While the platform requires users to provide a date of birth during the registration process and utilizes automated systems to identify minors, the regulator is concerned that these measures fail to account for a significant number of underage users. According to Ofcom’s latest research, TikTok remains the third most popular platform for children aged 8 to 14 in the UK, trailing only YouTube and WhatsApp. On average, these children spend nearly nine hours per week on video-sharing platforms.

The regulator has not yet reached a conclusion regarding compliance. TikTok has stated that it maintains age-appropriate policies and believes it has fulfilled its obligations under the Online Safety Act. The company continues to argue that its proprietary technology is designed to restrict access to inappropriate content based on the user’s verified age profile.

Broader Context of Online Safety Enforcement

This inquiry occurs amid intense political pressure in the UK to tighten restrictions on social media use for those under 16. The government is currently evaluating policies that could mandate stricter age-verification processes across the tech sector. Ofcom’s research suggests that even with existing measures, technological gaps persist across the industry. For example, the regulator noted that despite the introduction of age checks on dating apps, an estimated 10% of 15- to 17-year-olds are expected to continue using three of the most popular services through December 2025.

The scope of the investigation extends beyond video-sharing platforms to include the wider internet infrastructure. Ofcom has highlighted that children frequently bypass age restrictions by using search engines to locate uncensored websites. Data indicates that approximately one-third of first-page results on Google and 54% of results on Bing lead to websites that do not implement robust age-verification procedures.

Potential Consequences for Platform Providers

The UK’s Online Safety Act grants Ofcom significant enforcement powers to ensure compliance. Beyond the substantial financial penalties, which are calculated based on a percentage of global revenue, the regulator maintains the authority to issue enforcement notices. In extreme cases of non-compliance, these notices could lead to the recommendation of technical measures, including the blocking or limitation of a service within the UK. As the investigation progresses, Ofcom intends to determine whether TikTok’s current safety architecture provides a sufficient barrier against the risks of grooming, bullying, and exposure to sexually explicit or psychologically harmful material.
