The Department for Energy Security and Net Zero (DESNZ) has published a report, detailing the contributions of the UK Support Programme (UKSP) to the International Atomic Energy Agency (IAEA) Safeguards from 2021 to 2024. Between 1 April 2021 and 31 March 2024, the UKSP provided over £5m in in-kind and financial support to over 35 tasks within the IAEA's Development and Implementation Support Programme for Nuclear Verification. Key areas of assistance included the routine analysis of safeguards inspection samples, provision of open source information, delivery of training events for IAEA staff, promotion of UK technology solutions, and extra-budgetary financial contributions to critical IAEA projects, such as 'Keeping Safeguards IT Updated' and 'COMPASS', which aims to build State capacity on safeguards implementation.

The Department for Energy Security and Net Zero (DESNZ) has published a report, reviewing different approaches to emissions measurement and reporting, and how these approaches support decarbonisation outcomes. The report makes five main recommendations to overcome the challenges to, and increase the effectiveness of, emissions reporting in driving decarbonisation in the public sector, including clear and consistent guidance, emisson database and tools, and capacity building, among other aspects. The research was conducted by the Energy Saving Trust on behalf of the DESNZ.

The Department for Energy Security and Net Zero (DESNZ) has published a research report examining the technical readiness, cost implications and deployment barriers associated with hydrogen-based power generation technologies in the UK. Commissioned from Baringa, the report analyses a range of plant archetypes, including turbines, internal combustion engines and electrochemical systems. It covers several key topics, including: (1) the cost of retrofitting or repowering existing unabated gas plants to run on 100% hydrogen; (2) the cost of blending hydrogen into existing unabated gas plants; (3) barriers to deployment and scale-up and (4) how costs are expected to evolve over time as the technology matures.

The Department for Energy Security and Net Zero (DESNZ) has published a resource page, outlining the UK's carbon capture, usage and storage (CCUS) regulatory framework and the government's efforts to advance CCUS development and deployment both domestically and internationally. The page provides links to a collection of key policy documents, consultation outcomes, and business models, covering a range of CCUS-related topics, including the government’s Cluster Sequencing approach, recent milestones such as the £21.7bn funding commitment announced in October 2024, and international collaboration initiatives. The page also highlights the UK's hydrogen strategy and the role of the CCUS Council, among other topics.

The Department for Energy Security and Net Zero (DESNZ) has published its response to the consultation on extending the Energy Company Obligation 4 (ECO4) scheme, confirming a nine-month extension to 31 December 2026. The extension will maintain the current obligation for larger energy suppliers to achieve annual bill savings through energy efficiency and heating measures in households. However, DESNZ has confirmed that there will be no extension to the Great British Insulation Scheme, no increase in targets and no carry-over arrangements to support remediation or facilitate an orderly scheme closure.

The Department for Energy Security and Net Zero (DESNZ) has published the response to section 2 of its call for evidence on solar canopies and electric vehicle (EV) charging (which ran from 7 May 2025 to 18 June 2025), focusing specifically on EV charging infrastructure and planning. The response revealed that the vast majority of respondents supported simplifying the installation process for EV chargepoints. There was also broad support for extending Permitted Development Rights (PDRs) for EV charging and for providing enhanced training and guidance for both industry professionals and local authority officers.

The Department for Energy Security and Net Zero (DESNZ) has published its response to the consultation on extending recognition of Conformité Européenne (CE) marking for ecodesign regulations and confirms that it will lay a statutory instrument in summer 2026 to extend CE marking recognition to products regulated under Regulation (EU) 2024/1781 (the Ecodesign for Sustainable Products Regulation (ESPR)). DESNZ states that the change will allow products that meet both Great Britain (GB) and EU ecodesign requirements to continue to be placed on the GB market without requiring an additional UK Conformity Assessed (UKCA) marking, reducing costs and administrative burdens for businesses while providing regulatory certainty. The measure will apply in GB and is expected to take effect from 2027, when the first EU ecodesign measures under ESPR come into force. Respondents supported the proposal, highlighting benefits including lower compliance costs, reduced complexity, continuity of existing arrangements and fewer barriers to trade. DESNZ states that the measure will not align GB product standards with those of the EU, but will continue to recognise the CE mark for products that meet both GB and EU ecodesign requirements.

The Department for Energy Security and Net Zero (DESNZ) has published its response to the consultation on proposed amendments to the Plugs and Sockets etc. (Safety) Regulations 1994, SI 1994/1768, and the Plug-in Solar Device Interim Product Specification (IPS), confirming that it will proceed with both measures, subject to targeted refinements. The government states that the amendments will establish a limited approval route for standard plugs used with compliant plug-in solar devices without battery storage, while the IPS will set out interim technical and safety requirements pending the development of permanent standards. DESNZ also confirms that the final IPS has been strengthened by clarifying product scope, installation requirements, consumer information, circuit identification, mounting, compliance arrangements and fire safety measures. It further states that consumer guidance will be published alongside the regulatory changes to support the safe deployment of plug-in solar devices.

The Department for Energy Security and Net Zero (DESNZ) has published the response to its March 2023 consultation on updates to the 2009 Carbon Capture Readiness (CCR) requirements. The summary of responses outlines the feedback received on expanding and updating the CCR requirements, which will now be referred to as Decarbonisation Readiness requirements. It also addresses the transition of these requirements from the planning consent process to environmental permitting.

The Department for Energy Security and Net Zero (DESNZ) has published the response to its December 2023 consultation on a market intervention to support hydrogen to power (H2P) deployment. Following stakeholder feedback, the government confirmed that it will introduce a market intervention in the form of a Hydrogen to Power Business Model (H2PBM), incorporating elements of the Dispatchable Power Agreement, to de-risk investment and accelerate H2P deployment. DESNZ intends to consult with stakeholders on H2PBM design principles in Spring 2025 and seeks to facilitate H2P participation in the Capacity Market as soon as practicable.

The Department for Energy Security and Net Zero (DESNZ) has published the response to its December 2023 consultation on the proposed Heads of Terms for the Carbon Capture and Storage (CCS) Network Code. The Code is part of the new regulatory regime governing the arrangements between CO2 network users and transport and storage companies. DESNZ intends to publish the full text of the Code in early 2025, along with additional explanatory materials in due course, providing further details on policy responses and the policy rationale on specific topics. Alongside the response, DESNZ has also published a spreadsheet with an example calculation of the transport and storage charging formula.

The Department for Energy Security and Net Zero (DESNZ) has published the response to its March 2024 consultation on adjusting the introduction date of the Clean Heat Market Mechanism (CHMM) scheme. Following stakeholder feedback, DESNZ confirmed that the CHMM will launch on 1 April 2025. The response also outlines two key adjustments to the scheme design: the payment-in-lieu level for missing credits in the scheme's first year has been reduced from £3000 to £500, and the period for counting boiler sales has been aligned with the new launch date.
