The Regulations brought into force specific sections of the Online Safety Act 2023, primarily mandating CSEA content reporting duties for regulated user-to-user services effective April 7, 2026.

These Regulations, known as the Online Safety Act 2023 (Commencement No. 7) Regulations 2026, are made by the Secretary of State under the authority of the Online Safety Act 2023 to bring specific provisions of that Act into force on April 7, 2026, primarily focusing on establishing the mandatory duty for providers of regulated user-to-user services to report Child Sexual Exploitation and Abuse (CSEA) content to the National Crime Agency, alongside related offenses, supplementary reporting requirements, and powers for the regulator to obtain information.

The Regulations added offences related to encouraging serious self-harm and specific digital sexual offences to Schedule 7 of the Online Safety Act 2023 and revoked the 2024 amending regulations.

These Regulations amend Schedule 7 of the Online Safety Act 2023 by designating specific criminal acts as 'priority offences,' which imposes specific duties on online service providers to tackle content related to these crimes.

Specifically, the Regulations introduce an offence concerning encouraging or assisting serious self-harm and update provisions regarding offences under the Sexual Offences Act 2003 related to sharing intimate images, having been approved by Parliament and extending across the UK. The legal instrument also revokes the previous related amendment regulations from 2024.

The regulations specified the threshold figure for Online Safety Act 2023 fees as £250 million, effective for the charging year commencing April 1, 2026, and extended across the UK.

These Regulations, made by the Secretary of State following advice from Ofcom under the powers granted by the Online Safety Act 2023, establish the "threshold figure" at £250 million.

This figure determines which providers of regulated online services must notify Ofcom and pay fees to cover the regulator's online safety functions, with the threshold taking effect from the charging year beginning on 1st April 2026.

The Secretary of State revoked the Online Safety (CSEA Content Reporting by Regulated User-to-User Service Providers) Regulations 2025 under powers granted by the Online Safety Act 2023.

These Regulations, enacted by the Secretary of State using powers under the Online Safety Act 2023, officially revoke the earlier Online Safety (CSEA Content Reporting by Regulated User-to-User Service Providers) Regulations 2025, effective from November 2nd, 2025, across the whole of the UK, following consultation with the NCA and OFCOM.

The instrument revoked the prior regulations that scheduled specific child protection reporting duties under the Online Safety Act 2023 to commence on November 3rd, 2025.

These Regulations, made by the Secretary of State under the Online Safety Act 2023, revoke the Online Safety Act 2023 (Commencement No. 5) Regulations 2025, thereby preventing specific provisions of the Act that mandate certain user-to-user service providers to report child sexual abuse and exploitation content to the National Crime Agency from coming into force on their scheduled date of November 3rd, 2025; this legislative action extends across England, Wales, Scotland, and Northern Ireland and is stated not to require a full impact assessment.

The Online Safety Act 2023 (Qualifying Worldwide Revenue) Regulations 2025 were enacted, defining the calculation of qualifying worldwide revenue for online service providers to determine fees payable to Ofcom and maximum penalty amounts.

These regulations, effective October 8, 2025, define how to calculate qualifying worldwide revenue (QWR) for online service providers under the UK's Online Safety Act 2023.

The QWR determines fees paid to Ofcom and the maximum penalties for violations.

Part 2 details QWR calculation for fee-setting, focusing on revenue directly related to regulated services.

Part 3 defines QWR for calculating maximum penalties for groups of entities, considering all revenue (regardless of service relation).

The regulations aim for financial transparency and consistent enforcement.

The Online Safety Super-Complaints (Eligibility and Procedural Matters) Regulations 2025 were enacted, establishing eligibility criteria and procedures for super-complaints regarding online safety to OFCOM.

These regulations, effective December 31, 2025, govern the submission of super-complaints regarding online safety to OFCOM under the Online Safety Act 2023.

They define eligibility criteria for entities submitting complaints, specifying requirements for supporting evidence and the information to be included in the complaints.

The regulations also outline grounds for rejecting complaints, procedures for OFCOM's response, and restrictions on complaint submissions.

Section 210 of the Online Safety Act 2023 was brought into force, repealing Part 4B of the Communications Act 2003 and ending a transition period for online video-sharing platforms.

These regulations bring into force section 210 of the Online Safety Act 2023 on July 25, 2025.

This section repeals Part 4B of the Communications Act 2003, ending a transition period that began in January 2024.

The change puts video-sharing platforms under the Online Safety Act's updated duties of care.

The regulations apply across England, Wales, Scotland, and Northern Ireland.
