TikTok UK Investigation: Age Checks and Child Safety Risks 2026

TikTok is facing a formal UK investigation over concerns it has failed to protect children from harmful content, with the online regulator Ofcom citing age check failures as a key issue. The social media platform’s approach to verifying user ages may have put minors at risk of exposure to dangerous posts about disordered eating, self-harm, and pornography.

Why Ofcom Is Investigating TikTok

Ofcom announced the investigation under the Online Safety Act, which came into effect nearly a year ago. The regulator said TikTok’s method of inferring children’s ages through signals may not correctly identify a significant proportion of underage users. This could violate legal obligations to protect minors from harmful content.

Potential Penalties for Non-Compliance

If TikTok is found in breach, it could face fines of up to £18 million or 10% of qualifying worldwide revenue. In severe cases, Ofcom can apply to block or restrict the platform in the UK. The investigation aims to determine whether age assurance measures are “highly effective” at distinguishing children from adults.

How TikTok Currently Checks Ages

TikTok requires users to enter a date of birth when creating an account. It also uses technology that analyzes signals to detect if someone may not meet the minimum age requirement. However, Ofcom believes these methods may be insufficient, especially as AI-generated threats evolve.
