United Kingdom: Office of Communications released final guidance on super-complaints under Online Safety Act

On 10 February 2026, the Office of Communications (Ofcom) released guidance on super-complaints under the Online Safety Act 2023. The guidance specifies how an eligible entity can submit a written, evidence-backed super-complaint regarding features of regulated services, provider conduct, or both. Such complaints may be made where these features or conduct are, appear to be, or present a material risk of causing significant harm, significantly adversely affecting freedom of expression within the law, or otherwise having a significant adverse impact on UK users or the public. The guidance also outlines eligibility criteria, admissibility requirements, the submission form, evidential expectations, and restrictions on submitting illegal content. It describes Ofcom’s process and timelines, including normally determining eligibility within 30 calendar days (or 15 in limited repeat-eligibility cases) and responding and publishing a response within 90 calendar days after determining eligibility if the super-complaint is admissible.
