Briefings
UK household energy bills hit a record high in October 2026, reaching a cap of £1,723 annually, driven primarily by wholesale gas costs and network investment costs. A surge in wholesale costs from the Iran war accounts for over 80% of the bill increase since 2020, while network charges rose 50% between 2025 and 2030 due to Ofgem-approved investments totaling £29bn. The price cap for January 2027 is forecast to rise by 25%, potentially pushing annual bills toward £2,200. Uncertainty remains regarding whether policy costs or climate transition strategies will significantly impact future bill levels.
Key points
- Wholesale gas costs, tied to international energy prices, account for more than 80% of the rise in UK household energy bills since 2020.
- Network charges increased by approximately 50% between 2025 and 2030 following Ofgem's approval of £29bn in upfront grid investment.
Context
Carbon Brief analyzes the drivers of high UK energy bills, noting that while policy costs are a minor component, they are underrepresented in public narratives. The findings highlight the tension between energy security investments and climate goals, with the Iran war acting as a key external factor in recent price spikes.
Limitations
The analysis relies on data from Nesta and Ofgem reports available up to October 2026. Specific forecasts for 2027 are projections based on current trends, and the exact impact of the Iran war on future bill levels is not quantified beyond the 80% wholesale cost attribution.
