LONDON—Ofcom, the United Kingdom’s digital regulator, announced Wednesday that it is investigating TikTok as it released its first report on age-verification use since the country’s Online Safety Act took effect last summer.
Over the past year, major digital platforms operating in the U.K. have rolled out age checks at what Ofcom described as an “unprecedented scale.” The regulator said more than 69 million checks have been completed across 32 platforms.
Ofcom said the measures are an important step as the country considers a ban on social media use for people aged 16 and under. Among adult-entertainment platforms and pornography websites, the 10 most popular sites in the U.K. and most of the top 100 porn sites have introduced age checks. Ofcom said the share of minors asked to verify their age before accessing a site rose from 25 percent in July 2025 to 43 percent in January 2026.
Ofcom noted, “Among the minority of online children who attempt to access pornography (8%), the presence of age checks acts as an effective deterrent. Half of these children only reached sites with age checks in place. Nearly nine in ten of these children’s visits (87%) to porn sites were for under 30 seconds, and 65% were for less than 10 seconds.”
Dame Melanie Dawes, Ofcom’s chief executive, praised the agency’s work.
“Age checks are a cornerstone of the U.K.’s online safety laws,” she said. “When implemented properly, our evidence shows that age checks are helping to create a safer life online for children in the U.K.
“But the job is not done, and tech companies need to go further. Too many services have no or inadequate age checks in place, which is not good enough,” Dawes added.
Dawes said Ofcom has opened an investigation into TikTok. The video-sharing platform is also used by adult-industry creators and companies to promote scenes and productions. The new enforcement effort also includes search engines such as Google and Bing.
She explained, “We’ve today launched an investigation into whether TikTok’s age checks are effective in preventing children from seeing harmful content on its platform. And search engines must urgently work with us to solve the problem of children finding porn sites without age checks too easily via their results pages.
“As the U.K. prepares for further new social media restrictions at 16, the age check landscape is already shifting towards a stronger, whole-of-system approach, which is important to avoid any single point of failure,” Dawes concluded.
“We want to see continued innovation from the wider tech industry to strengthen protections for children—including from operating systems and at an app store and device-level.”
A TikTok spokesperson said the company “strictly enforces age-appropriate experiences through expert-informed platform rules and advanced age inference technologies, in line with major industry peers.” The spokesperson added that TikTok is “confident” it complies with the requirements.
