TikTok Under UK Investigation for Failing to Protect Children Online
Britain's media regulator has opened a formal probe into whether TikTok's age checks are good enough to stop children seeing content about self-harm, suicide and pornography.
Key points
- Ofcom, the UK's official media and communications regulator, launched a formal investigation into TikTok in 2025.
- The probe centres on whether TikTok's age verification, the system it uses to check how old its users are, is working.
- Ofcom has "particular concerns" that children can access self-harm, suicide and pornographic content on the platform.
- The investigation comes almost a year after the Online Safety Act, a UK law requiring platforms to shield children from harmful material, came into force.
Britain's media regulator, Ofcom, has opened a formal investigation into TikTok over fears the platform isn't doing enough to keep children safe.
The core concern is age verification: the checks TikTok runs to work out whether a user is a child or an adult. Ofcom believes those checks may be too weak, leaving younger users exposed to posts about self-harm, suicide and explicit content.
The investigation was first reported by The Guardian.
Why does this matter to parents?
It means regulators aren't satisfied TikTok is following rules that already exist. If your child uses TikTok, they may be seeing content the law was specifically designed to block.
The Online Safety Act, passed to force social media companies to protect children from the worst material online, has been in effect for nearly a year. A formal Ofcom investigation is serious: it can end in fines or other legal consequences if the regulator finds TikTok has broken the rules.
Age verification is the sticking point. TikTok, like most platforms, asks users to enter a birth date on sign-up. A child can simply type a false date and gain full access. Stronger checks exist, such as passport scans or bank-card confirmation, but TikTok hasn't made them standard.
The regulator hasn't reached a verdict. An investigation means Ofcom is formally gathering evidence, which can take months, and TikTok will have the chance to respond.
For parents right now: TikTok's "Family Pairing" feature lets an adult account link to a child's and set content limits. Checking what categories are restricted is the most direct action available while the investigation runs.
Should you expect more probes like this?
Almost certainly. We first covered the Online Safety Act's enforcement machinery on 16 July 2026, and this investigation is the sharpest move yet because it targets the very mechanism platforms rely on to prove they're protecting children at all. The EU is pushing similar pressure on different platforms; our earlier story on how European regulators threatened Meta over addictive design shows the direction of travel.
What to watch: whether Ofcom publishes interim findings before the investigation closes, and whether TikTok moves to roll out stronger age checks proactively to head off a fine. That's the tell. Platforms that wait for a verdict rarely come out of it looking good.
