Switched the inflation indexing for renewable electricity buy-out prices and mutualisation caps from RPI to CPI effective April 2026.

This Order amends the Renewables Obligation Order 2015 to change the inflation index used for adjusting the buy-out price and the mutualisation cap for electricity suppliers in England and Wales.

It replaces the Retail Prices Index (RPI) with the Consumer Prices Index (CPI) for all obligation periods starting on or after 1 April 2026.

These changes apply to all licensed electricity suppliers who must either produce Renewables Obligation Certificates (ROCs) or make cash buy-out payments to the Gas and Electricity Markets Authority (Ofgem).

Modified the legal framework for how local authorities and the Secretary of State revoke or prepare joint minerals and waste planning documents in England.

These regulations amend previous 2026 legislation to modify the Planning and Compulsory Purchase Act 2004 as it relates to minerals and waste plans in England.

The instrument establishes specific requirements for minerals and waste planning authorities to revoke existing documents when new plans take effect and clarifies the legal framework for joint plans.

It directs how the Secretary of State may intervene or revoke documents at the request of local authorities and specifies that joint plans must be adopted by all participating authorities to be valid.

The Regulations appointed April 1, 2026, as the date when the UK Aggregates Levy ceases to apply in Scotland under the provisions of the Scotland Act 2016.

These Regulations, made by HM Treasury, formally establish 1st April 2026 as the appointed day for the commencement of amendments made under Section 18 and Schedule 1 of the Scotland Act 2016, which will stop applying the UK Aggregates Levy to the commercial exploitation of aggregate occurring within Scotland on or after that date.

The Regulations amended six existing sets of health and safety legislation to explicitly include definitions, licensing rules, operator responsibilities, and safety case requirements for Carbon Capture, Utilisation and Storage (CCUS) and offshore hydrogen production activities.

These Regulations, made on 10th March 2026 and effective 6th April 2026, introduce amendments across six major pieces of UK health and safety legislation governing offshore installations and pipelines, primarily to formally incorporate activities related to Carbon Capture, Utilisation and Storage (CCUS) and offshore hydrogen production into existing safety, management, regulatory, and reporting frameworks, ensuring these nascent energy sectors are regulated under consistent safety standards previously applied to the offshore oil and gas industry.

The regulations amended the 2005 Climate Change Levy Regulations to specify electricity used in hydrogen electrolysis and natural gas used in sodium bicarbonate production as non-fuel uses exempt from the levy.

The Treasury enacted these Regulations on March 11, 2026, immediately amending the Climate Change Levy (Fuel Use and Recycling Processes) Regulations 2005 to specify certain industrial uses as exempt from the Climate Change Levy.

Specifically, the amendments introduce hydrogen production via electrolysis and the use of natural gas as a carbon dioxide source in sodium bicarbonate production as 'wholly non-fuel uses', thereby removing the levy charge on the energy inputs for those specific processes.

The regulations specified the mandatory disclosure periods for protected carbon storage and offshore petroleum information and samples obtained by the OGA, and amended a related 2018 disclosure regulation.

The Oil and Gas Authority (Carbon Storage and Offshore Petroleum) (Specified Periods for Disclosure of Protected Material) Regulations 2025 specify the regulatory windows following data collection during which the Oil and Gas Authority (OGA) or subsequent holders can disclose protected material, including information and samples, related to carbon capture and storage (CCS) and offshore petroleum activities.

These regulations establish different disclosure timelines based on the sensitivity and nature of the material—some information can be published immediately, while detailed technical data, well information, injection/production records, and physical samples are subject to defined confidentiality periods, often contingent on reporting deadlines, system closures, or licence determination events.

Furthermore, the instrument amends a 2018 regulation concerning offshore petroleum data to align its disclosure deadline with the "reporting deadline" specified by the OGA.

The Secretary of State made an Order granting development consent for the Helios Renewable Energy Project after examination by the Examining Authority and consideration of all relevant environmental and policy matters.

The Helios Renewable Energy Project Order 2025 grants development consent under the Planning Act 2008 for the construction, operation, and decommissioning of a solar generating station and battery energy storage system in the North Yorkshire Council area, defining the scope of the authorised development, granting the undertaker powers for compulsory acquisition of land or rights, and establishing detailed preliminary provisions, street works, and specific protective requirements for various statutory undertakers including electricity, gas, water, drainage, and railway interests.

The Secretary of State approved a non-material change application, resulting in this Order which amended the 2022 DCO via defining Defra, specifying the undertaker, and altering the HHW SAC compensation requirements to include an option for Marine Recovery Fund payments.

This Order enacts non-material changes to the Norfolk Vanguard Offshore Wind Farm Order 2022, effective from December 19th, 2025, following an application for amendment.

Key revisions include adding a definition for 'Defra,' clarifying the named 'undertaker' as Norfolk Vanguard West Limited, and significantly modifying Part 3 of Schedule 17, which relates to compensation for impacts on the Haisborough, Hammond and Winterton Special Area of Conservation (HHW SAC) by introducing the Marine Recovery Fund Payment as an alternative management measure to specific marine debris removal tasks.
