These Regulations, issued by the Minister for the Cabinet Office with the consent of the Department of Finance for Northern Ireland, update specific financial threshold amounts within the Procurement Act 2023, effective from January 1, 2026.

The primary goal is to ensure the UK's public procurement rules, particularly those governed by the GPA, align with current international standards, while also correcting an inconsistency in below-threshold contract procedures and detailing specific threshold columns related to contracts regulated by the Welsh Ministers.

These Regulations amend the Clean Heat Market Mechanism (CHMM) Regulations 2025, which established the mandatory scheme requiring boiler manufacturers to meet escalating targets for installing low-carbon heat pumps proportionate to their fossil fuel boiler sales in the UK. The amendments officially designate the Microgeneration Certification Scheme (MCS) as the sole approval scheme for CHMM compliance, update the criteria for what qualifies as a hybrid heating system, and most significantly, increase the required low-carbon heat installation target for scheme years beginning April 1, 2026, from 6% to 8% of relevant boiler sales.

These Regulations, made by the Secretary of State with consent from the Scottish Ministers and the Department of Justice for Northern Ireland, exercise powers under the Private International Law (Implementation of Agreements) Act 2020 to extend the 'operative period' for making associated regulations by five years.

The instrument formally extends the deadline for creating subordinate legislation under Section 2 of the 2020 Act from 13th December 2025 until the end of 12th December 2030, applying across England, Wales, Scotland, and Northern Ireland.

The Secretary of State enacted these Regulations using the power granted by the Trade Act 2021 to extend the deadline for making regulations necessary to implement international trade agreements to which the UK is a signatory.

Specifically, the five-year period during which this regulation-making power can be used is extended, meaning no regulations under section 2(1) of the Act can be made after the end of ten years beginning with IP completion day.

Statutory approval from both Houses of Parliament preceded the coming into force of these regulations on December 30th, 2025, and they apply across England, Wales, Scotland, and Northern Ireland.

This statutory instrument, made by the King in Council under the powers granted by the Education Act 2005, formally appoints the individuals listed in the accompanying Schedule to serve as His Majesty’s Inspectors of Education and Training in Wales (or Arolygwyr Ei Fawrhydi dros Addysg a Hyfforddiant yng Nghymru), and it stipulated that the Order comes into force on November 20th, 2025.

The Control of Mercury (Enforcement) (Amendment) Regulations 2025 amend the 2017 Regulations to implement new restrictions on mercury, focusing specifically on dental amalgam within Northern Ireland as required by the 2024 EU amendment regulation concerning mercury.

These changes update customs enforcement powers regarding import and export prohibitions and clarify temporary exemptions for existing use and import of dental amalgam by registered dental professionals in Northern Ireland until the end of 2034, while also adding corresponding reporting duties.

This Order, made by the King in Council under powers granted by the Government of Wales Act 2006, officially names itself the Welsh Parliament (Disqualification) Order 2025 and revokes the previous 2020 Order, although the 2020 Order remains effective for any Senedd election polling before April 6, 2026.

The primary function of the 2025 Order is to designate specific public offices listed in the Schedule whose holders are disqualified from being elected or remaining as a Member of the Senedd (MS), with the disqualification commencing its full effect for elections held on or after April 6, 2026.

These Regulations, made by the Secretary of State for Northern Ireland using powers under the Northern Ireland Troubles (Legacy and Reconciliation) Act 2023, formally amend a previous commencement regulation (S.I. 2024/584).

Specifically, they extend the transitional deadline for investigating bodies to prepare or complete investigation reports or take subsequent actions from October 31, 2025, to April 30, 2026.
