Analysis: the Ofcom harmful content report, the regulator’s first statutory review of material harmful to children, finds children’s exposure has not fallen. Both sides of the under-16 ban debate can read something into it.
Ofcom’s first statutory report on content harmful to children, published on 22 October 2026, found no significant change in the proportion of UK children encountering harmful material online in the first nine months after new child safety duties took effect in July 2025. The regulator said technology firms needed to do more and faster. The findings arrive as the government prepares to ban social media for under-16s.
What the Ofcom harmful content report found
The report is required by section 63 of the Online Safety Act 2023, which obliges Ofcom to review how often children meet harmful content and whether the law’s categories of such content need changing. According to the Press Association’s report of the findings:
- Most UK children said they had seen at least one piece of harmful content in a four-week period.
- 14% of 11 to 17-year-olds had seen suicide or self-harm content in the previous four weeks, and 23% had seen eating disorder content.
- About half of teenagers who saw content about weapons said it made them feel less safe at school or in their neighbourhood.
- Ofcom found no new evidence that the severity of harm to children had changed.
Ofcom said firms “need to go much further and faster to protect children online”, and warned that those failing to meet their duties could expect enforcement action. It also pointed to what it called significant progress on age checks, protections against grooming and safeguards against child sexual exploitation.
On the law itself, legal publisher LexisNexis reported that Ofcom recommended adding content promoting body stigma and depression to the “priority” category, which would strengthen platforms’ duties to protect children from it. Ofcom did not recommend other changes to the categories at this stage.
Why it matters for the under-16 ban
In June 2026 the government announced plans to bar social media platforms from serving under-16s, modelled on Australia’s ban, with messaging, education, shopping and music services excluded. Reports by the Society for Computers and Law and DLA Piper said the first regulations could take effect in spring 2027, using powers in the Children’s Wellbeing and Schools Act 2026. Ofcom has also said it would give Parliament a rapid assessment of age-checking methods for the ban by the end of October.
How supporters of a ban read the report
For those who back an age limit, the report supports their central argument: rules requiring platforms to make their services safer have not yet reduced how much harmful material children see. The Commons Education Select Committee had already called in May 2026 for a statutory ban and limits on addictive design, arguing that platforms had not shown enough accountability. Campaigners such as Smartphone Free Childhood have also pressed for a higher minimum age. Children First’s Linda Jardine said the report painted a stark picture of the dangers children face.
How sceptics read it
A more cautious reading is that nine months is an early point at which to judge the Online Safety Act, and that Ofcom’s own response focuses on enforcing the existing duties harder rather than replacing them. Children’s charities have been divided on a ban. When the government’s consultation opened, the NSPCC and 5Rights Foundation warned that a blanket ban could create a false sense of safety and push children towards less regulated corners of the internet, while the Molly Rose Foundation urged ministers to follow the evidence rather than adopt simple fixes.
There is also a practical question. Any ban depends on platforms reliably identifying under-16s. Ofcom’s July 2026 report found that age checks were spreading fast, with the share of children meeting highly effective checks rising from 25% to 43% between July 2025 and January 2026. But, as summarised by the law firm Lewis Silkin, Ofcom also doubted that age-estimation methods used by some platforms could support a meaningful ban on their own.
What the evidence does and does not show
The report shows that, so far, the Online Safety Act’s child protection duties have not measurably reduced how often children meet harmful content. It does not show whether that is because the rules are too weak, because enforcement is still bedding in, or for other reasons. Nor does it test whether an age ban would work better; that will depend on the final regulations and on how well age checks perform.
