United Kingdom: Office of Communications adopted notification guidance for online safety fees

On 21 November 2025, the Office of Communications (Ofcom) adopted the notification guidance for online safety fees. The guidance explains how regulated service providers must notify Ofcom and provide evidence of their qualifying worldwide revenue. The guidance applies to social media platforms, search engines, and pornography services with links to the United Kingdom that exceed the revenue threshold set by the Secretary of State. Providers must submit qualifying worldwide revenue returns through Ofcom's Online Safety fees portal during designated notification windows. They must provide evidence substantiating their regulated services and qualifying worldwide revenue. The guidance covers practical notification processes, required evidence standards, and data handling procedures. Ofcom also issued a single statement pointing out the complementarity of the notification guidance with its guidance on qualifying worldwide revenue.
