Version 2.2 remains the current guidance. The relevant amendments are contained in the Green Gas Support Scheme (Amendment) Regulations 2026, SI 2026/1051. Most provisions come into force on 16 October 2026, with certain provisions relating to scheme years and reconciliation coming into force on 1 April 2027.

Ofgem has published guidance for participants of the renewables obligation (RO), feed-in tariffs (FIT), renewable energy guarantees of origin (REGO) and smart export guarantee (SEG) schemes who are thinking of co-locating electricity storage facilities with their accredited RO or REGO generating station, FIT installation or SEG installation. In light of the expected increased uptake of co-located storage, the purpose of the guidance is to provide clarity to participants about the treatment of storage facilities within the framework of the schemes.

Ofgem has published its final decision and direction on two key regulatory documents for the National Energy System Operator (NESO), to take effect from 1 April 2025. The documents—the Performance Arrangements Governance document and Licence Expectations document—establish the framework for NESO's performance assessment and licence obligations during the RIIO-2 Business Plan 3 period. Following a February 2025 consultation that received six responses, Ofgem maintained its core policy positions while making targeted clarifications to improve document clarity, particularly regarding strategic energy planning expectations and assessment processes. The framework will apply until 31 March 2026.

Ofgem has published the final Regulatory Instructions and Guidance (RIGs) for the Successor Licensee of the Smart Meter Communication Licence. This follows its June 2025 consultation, conducted as part of the ongoing review of the Data Communications Company (DCC)'s regulatory framework ahead of the current licence's expiry in September 2027. The RIGs will support the implementation of the first ex-ante cost control cycle for the DCC Successor Licensee. Key changes include: (1) a shift from ex-post to ex-ante reporting; (2) the introduction of service families and budget ringfencing; and (3) the inclusion of uncertainty mechanisms, among other updates.

Ofgem has published its final decision to implement the Supplier of Last Resort (SoLR) Levy Offset, following policy and statutory consultations held in 2024.

The changes aim to reduce the impact of supplier failures on consumers and form part of Ofgem’s wider programme to strengthen financial resilience in the retail energy market.

Ofgem has confirmed a five-year investment package, covering the period 2023–2028, for six electricity Distribution Network Operators (DNOs) across 14 local networks to allow then to deliver cheaper, cleaner, and more reliable grids at no extra cost to customers. The RIIO-ED2 price control will also aim to move away from importing fossil fuels and relying on expensive gas. The announced RIIO-ED2 final determinations will be followed by a statutory consultation on the licence modifications that are necessary to implement the RIIO-ED2 settlement in December 2022. The licences and associated price control financial instruments will be confirmed in February 2023 and the RIIO-ED2 price control will commence on 1 April 2023.

Ofgem has published its final determinations on the National Energy System Operator (NESO)’s Business Plan 3 (BP3), setting out its expectations for NESO’s performance, reporting requirements, and position on how the plan delivers value for money to consumers. The final determinations confirm the positions outlined in Ofgem’s earlier draft, including the performance metrics NESO should use to measure success. Ofgem will evaluate NESO’s performance under BP3 in a Performance Assessment Report, expected to be published in summer 2026.

Ofgem has published its final template for a future code modification process and the establishment of connected stakeholder advisory forums (SAFs). The text was finalised following stakeholder engagement on a draft released as part of Ofgem's earlier decision on implementation of energy code reform under the Energy Act 2023 (TEA 2023). The outcome provides a summary of stakeholder input on the previously released text alongside the final templates and Ofgem's next steps in relation to delivery of a new governance framework for the Balancing and Settlement Code (BSC) and Retail Energy Code (REC), which together form Phase 1 of the TEA 2023 reforms. Reform of the Electricity Commercial Code (ECC) and Gas Network Code (GNC) is to follow beginning later this year in Phase 2, with Phase 3 of reform (covering the Electricity Technical Code (ETC) and Smart Energy Code (SEC)) commencing next year.

Ofgem has published its first good practice guidance on the ethical use of artificial intelligence (AI) in the energy sector, aimed at energy companies, industry stakeholders, and consumer groups. It encourages all energy companies to adopt the guidance as they implement AI-enabled systems. The guidance promotes the ethical deployment of AI technologies that are safe, secure, fair, and environmentally sustainable. It also outlines best practice frameworks covering governance, accountability, risk assessment and mitigation, and organisational competence, and features sector-specific examples of AI use in practice.
