On 6 March 2026, Ofgem published its decision on its second consultation on the implementation of energy code reform, which set out proposals to modernise Great Britain's regulatory energy codes. Phase 1 of the reform is expected to be implemented by the end of 2026.

Central to energy code reform are Ofgem's new powers under the Energy Act 2023 (EA 2023) to appoint and license code managers. Code managers will assume roles previously fulfilled by code panels and administrators, ensuring that industry codes evolve in line with Ofgem's annually published Strategic Direction Statement (SDS). The additional introduction of new Stakeholder Advisory Forums (SAF) will allow industry stakeholders to more actively contribute to the decision-making process.

Futureproofing Data Centres: How To Navigate Grid Constraints And Alternative Power Strategies

Scotland's Hydrogen Opportunity: Why Land, Infrastructure and Regulatory Certainty Matter

Scotland's hydrogen sector is advancing rapidly as developers and investors navigate the complex landscape of land rights, infrastructure requirements, and regulatory frameworks needed to achieve ambitious production targets. With 5GW targeted by 2030 and 25GW by 2045, the intersection of real estate, planning, and evolving EU standards will determine which projects successfully deliver low-carbon hydrogen production and export capabilities.
