British Energy Networks Set for £24bn Pound Grid Upgrade as Consumer Bills Rise

In a landmark decision, Britain’s energy watchdog Ofgem has authorised an unprecedented £24 billion investment in the nation’s electricity grid infrastructure. The investment package includes £15 billion for gas transmission and distribution networks through to 2031, whilst £8.9 billion is earmarked for high-voltage electricity network expansion—marking the most significant grid enhancement since the 1960s.

The ambitious programme will facilitate 80 major energy infrastructure projects by 2030, reflecting the government’s strategic push towards renewable energy development and enhanced energy security. However, British households will bear the financial burden, with bills projected to increase by £104 by 2031—comprising £30 for gas networks and £74 for electricity grid improvements.

Ofgem’s Chief Executive, Jonathan Brearley, emphasised the critical nature of this investment, stating that inaction would result in higher costs for consumers. The regulatory body maintains that the investment will ultimately prove cost-effective by enabling better utilisation of renewable energy sources and reducing dependence on expensive gas plants.

The timing coincides with Ofgem’s quarterly price cap adjustment, which has reduced typical annual dual-fuel bills by 7% to £1,720. Industry analysts at Cornwall Insight project a further modest decrease of £22 in October, bringing the typical dual-fuel consumer’s annual costs to £1,698.

The investment framework includes an increased return on equity for grid companies, rising to 6% from the previous 4.55%. While major utilities had sought returns of up to 6.9%, market reactions were positive, with shares in National Grid, SSE, and Iberdrola all trading higher following the announcement.

Energy Networks Association chief executive Lawrence Slade highlighted the unprecedented scale of investment, emphasising its crucial role in shaping Britain’s future energy system. The final decision on this comprehensive energy network spending plan is expected by year-end, with Ofgem promising strict oversight of project delivery and budgetary compliance.
