Ofcom publishes first review of content harmful to children

Ofcom, the UK communications and online safety regulator, published its first statutory review under section 63 of the Online Safety Act on 22 October 2026, finding that 73 percent of UK children aged 11 to 17 encountered harmful content online during a four-week period and that there was no significant change in exposure during the first nine months after children's safety duties came into force in July 2025. The review also found that generative AI search services returned harmful content, including depression and body stigma material, in a small proportion of queries, and that 14 percent of 11 to 17-year-olds reported exposure to suicide or self-harm content in the previous four weeks while 23 percent saw eating disorder content.

Before children encounter self-harm ideation or eating-disorder content in their feeds, targeted detection can intervene. Pattern-based monitoring surfaces children already in acute distress to a parent, school counsellor or crisis service and flags escalating contact from unknown adults who precede grooming or sextortion by months. Where a blanket duty imposed on platforms has not yet demonstrated a reduction in child exposure to harmful material, real-time monitoring at the point of contact intercepts the conversation or content before it reaches the child, without the privacy cost of handing regulators or employers a database of what every user said, and enables rapid professional response when a child already in crisis signals intent or method.
