The Treasury amended the 2025 Commencement No. 10 Regulations to save specific permissions granted by the PRA under the Capital Requirements Regulation and maintained the PRA's power to amend related delegated technical standards past January 1st, 2026.

The Treasury enacted these Regulations using powers under the Financial Services and Markets Act 2023 to amend the Financial Services and Markets Act 2023 (Commencement No. 10 and Saving Provisions) Regulations 2025.

The primary goal is to modify how permissions granted by the Prudential Regulation Authority (PRA) under provisions of the Capital Requirements Regulation are treated after their scheduled revocation takes effect on January 1st, 2026, by ensuring certain permissions continue to have effect under relevant sections of the Financial Services and Markets Act 2000 (FSMA 2000) and preserving the PRA’s power to update related delegated technical standards.

The regulations amended several customs regulations to update DCTS origin criteria, reclassified Vanuatu's trade status, adjusted regional cumulation groups, and revised version numbers for numerous supporting tariff and trade preference documents.

These Regulations, made by the Treasury and the Secretary of State under the Taxation (Cross-border Trade) Act 2018, introduce various amendments to UK customs regulations, primarily focused on updating the Developing Countries Trading Scheme (DCTS) origin rules and linked preferential arrangements, effective January 1, 2026.

Key changes involve differentiating origin rules for Enhanced Preference (EP) and Standard Preference (SP) countries, updating the criteria for 'economically vulnerable countries,' reclassifying Vanuatu from a Least Developed Country (LDC) to an 'other eligible developing country,' and updating the version numbers of several foundational customs reference documents.

The Regulations amended the 2023 Regulations to introduce deemed compliance pathways based on the Japan JC-STAR STAR-1 and Singapore Cybersecurity Labelling Scheme for product security and statements of compliance.

These Regulations amend the Product Security and Telecommunications Infrastructure (Security Requirements for Relevant Connectable Products) Regulations 2023 by introducing provisions that allow manufacturers of relevant connectable products to be treated as complying with UK product security requirements and the obligation to provide a statement of compliance if they meet specific criteria linked to existing cybersecurity labelling schemes from Japan (JC-STAR STAR-1) and Singapore.

The Merchant Shipping (Polar Code) (Safety) Regulations 2025 were enacted, implementing updated IMO requirements for polar navigation, extending compliance to smaller vessels, and amending preceding survey, certification, and fee regulations.

These Regulations, titled the Merchant Shipping (Polar Code) (Safety) Regulations 2025, update UK domestic law to incorporate the latest amendments from the International Maritime Organization (IMO) Resolutions MSC.532(107) and MSC.538(107) concerning ships operating in polar waters, effectively replacing the 2021 Regulations.

The new rules come into force on 1st January 2026 and apply to United Kingdom ships and specific non-UK ships operating in Arctic and Antarctic waters, extending mandatory safety requirements, including detailed structural, navigational, and training provisions from the Polar Code, to additional categories of ships such as smaller cargo ships, fishing vessels, and pleasure vessels, while also amending several existing pieces of maritime legislation relating to surveys, certification, and training fees.

The Regulations amended Part A of Annex 2 to Regulation (EU) 2017/852 by inserting new entries and associated phase-out dates for mercury use in several categories of devices, effective from December 23rd, 2025, across England, Wales, and Scotland.

The Secretary of State made The Control of Mercury (Amendment) Regulations 2025, obtaining consent from the Welsh and Scottish Ministers, to amend Part A of Annex 2 of Regulation (EU) 2017/852 on mercury.

These Regulations, which extend to England, Wales, and Scotland, introduce specific amendments to phase-out dates for mercury content in various products, including certain lighting types, sensing devices, and electronic components, aligning UK law with recent decisions made by the Conference of the Parties to the Minamata Convention on Mercury.

The Order amended the 2001 Block Exemption Order to remove its sunset clause, revised definitions for connecting services and vehicle classification, eliminated the definition of "working day," and set a new mandatory review schedule beginning in 2031.

This Order, enacted in exercise of powers under the Competition Act 1998, amends the Competition Act 1998 (Public Transport Ticketing Schemes Block Exemption) Order 2001 following a recommendation from the Competition and Markets Authority.

The key changes involve removing the fixed expiration date for the exemption, thereby making it permanent unless reviewed, adjusting definitions related to connecting services—specifically regarding trunk bus services—and removing the definition of a "working day" to align with the main Act.

The document confirms the amendments extend across England, Wales, Scotland, and Northern Ireland, and sets a new mandatory review date of 1st January 2031.

The Treasury amended Part 8C of the Corporation Tax Act 2010 to exclude low-rate simple interest from the 45% restitution interest tax charge and adjusted the assessment time limit for chargeable interest.

These Regulations, enacted by HM Treasury, amend Part 8C of the Corporation Tax Act 2010, which imposes a 45% corporation tax rate on restitution interest paid by HMRC. The amendments primarily serve to exclude simple interest awarded at a rate equivalent to or lower than a statutory rate from this special tax charge and modify the time limit for assessing this tax, allowing assessments to be made later if payments are accounted for before a final determination has been reached.

Legislation amended the 2017 Radio Equipment Regulations as they apply in Northern Ireland to incorporate additional essential safety and security requirements for internet-connected radio equipment originating from an EU Delegated Regulation.

The Radio Equipment (Amendment) (Northern Ireland) Regulations 2025 amend the 2017 Regulations specific to Northern Ireland to implement Commission Delegated Regulation (EU) 2022/30, which introduces new essential requirements for internet-connected radio equipment concerning network integrity, fraud protection for financial transactions, and user data/privacy protection.

The instrument also updates the necessary conformity assessment procedures to reflect these new security standards, enacted under the powers granted by the European Union (Withdrawal) Act 2018 and approved by resolution of both Houses of Parliament.
