The Aviation Safety (Amendment) Regulations 2025 enact changes to UK retained EU aviation safety legislation, primarily by amending Commission Regulations (EU) No 1321/2014 and 2018/1139.

These amendments focus on correcting cross-references and terminology within continuing airworthiness (Part-M), maintenance standards (Part-145), and maintenance licensing (Part-66 Appendix 8).

Key changes include updating rules for maintenance data access, refining conditions for acceptable component release documentation (like substituting Form 1 with a 'declaration of maintenance accomplished'), clarifying record-keeping mandates for maintenance organisations, and adjusting rules for re-taking Category L aircraft maintenance licence examinations.

These Regulations, made by the Secretary of State under the Data Protection Act 2018 (DPA), specify which public bodies qualify as 'qualifying competent authorities' to engage in joint processing of personal data with intelligence services under Part 4 of the DPA, a power enabled by the Data (Use and Access) Act to assist in safeguarding national security; the instrument lists various government departments, police forces, customs, and judicial/monitoring bodies as qualifying authorities, citing consultation with the Information Commissioner and Parliamentary approval, and stipulates that the regulations come into force twenty-one days after being made and extend across the UK.

These Regulations bring into force specific parts of the Economic Crime and Corporate Transparency Act 2023 concerning corporate governance, director duties, and the regime for People with Significant Control (PSCs), setting the main commencement date for these provisions as 18th November 2025.

Furthermore, the Regulations establish detailed transitional rules, particularly regarding the verification of identity for directors already in office before the commencement date and for existing registrable persons, specifying staggered deadlines based on birth month or existing notification statuses.

These Regulations, made by the Secretary of State for Transport under powers derived from Regulation (EU) 2018/858, introduce mandatory compliance with UNECE Regulations No. 155 (concerning cyber security and cyber security management systems) and No. 156 (concerning software updates and software update management systems) for vehicles seeking Great Britain (GB) type-approval.

The amendments update Annexes II, IV, and XII of Regulation (EU) 2018/858 to incorporate these UN requirements and specify implementation deadlines, and also amend Implementing Regulation (EU) 2020/683 to update the associated information documentation and certificates of conformity templates.

The Regulations come into force on 13th November 2025 and extend across England, Wales, Scotland, and Northern Ireland.

These Regulations amend existing UK legislation deriving from EU Regulations (EU) 2018/1139, specifically affecting Commission Delegated Regulation (EU) 2019/945 and Commission Implementing Regulation (EU) 2019/947 concerning Unmanned Aircraft Systems (UAS).

The amendments introduce UK-specific branding for drone classes (replacing 'C' with 'UK'), clarify scope by excluding UAS under 100g MTOM or those operated wholly indoors, and impose new technical requirements for direct remote identification and geo-awareness on certain classes, with most technical changes commencing in January 2028.

Furthermore, the rules delegate authority for approving conformity assessment bodies from the Secretary of State to the market surveillance authority.

These Regulations, made by the Treasury under powers in the Financial Services and Markets Act 2000, make technical amendments and transitional provisions concerning the Public Offers and Admissions to Trading Regulations 2024.

Specifically, they substitute a new provision for FCA investigation powers concerning entities subject to the 2024 Regulations, establish temporary arrangements for existing authorised persons applying to conduct the newly regulated activity of operating an electronic system for public offers, and introduce consequential amendments across various pieces of legislation, including primary and subordinate legislation and numerous UK sanctions regulations, to align them with the new framework.

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.

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.
