TikTok UK Investigation: Age Checks and Child Safety Risks 2026

TikTok is under a formal investigation by Ofcom over concerns it has failed to protect children from harmful content, highlighting critical age check failures. The UK regulator announced the probe, citing worries that TikTok's method of inferring ages may miss a significant proportion of children, exposing them to posts about disordered eating, self-harm, suicide, and pornography.

Why TikTok Faces Ofcom Investigation

Ofcom launched this investigation under the Online Safety Act, which took effect almost a year ago. The watchdog says TikTok's age assurance approach—using signals to estimate user age—may not be highly effective at correctly determining whether a user is a child. This puts minors at risk of encountering harmful content that the law aims to prevent.

Potential Penalties for Non-Compliance

If TikTok is found in breach, penalties could include fines up to £18 million or 10% of qualifying worldwide revenue, whichever is greater. In severe cases, Ofcom can apply to have sites blocked or restricted in the UK. The regulator emphasized it has not reached conclusions yet but is investigating whether TikTok failed to comply with legal obligations.

How TikTok Currently Checks Ages

TikTok states it requires users to enter a date of birth when creating an account. It also uses technology that looks at information, called signals, to check for indicators that someone may not meet the minimum age requirement. However, Ofcom believes these methods may be inadequate, especially as the UK government prepares to launch a social media ban for under-16s early next year, increasing scrutiny on age verification.

AI and New Threats to Children

The investigation comes as AI creates new frontiers of threats. Meta recently announced steps to alert parents and emergency services if children discuss suicide or self-harm with its AI chatbots on Instagram and Facebook. This highlights the growing need for robust safety measures across platforms.
