New UK regulations came into force on April 7, 2026 requiring user-to-user service providers to report all detected child sexual exploitation and abuse content to the National Crime Agency rather than just removing it. Providers must register with the NCA's reporting portal, classify reports into three priority levels with corresponding timeframes, and retain report reference numbers for five years, with non-compliance potentially resulting in penalties up to 10% of worldwide revenue or £18 million.
