Briefings
UK household energy bills hit a record high in October 2026, reaching a price cap of £1,723 annually, driven primarily by wholesale gas costs and network investment costs. Analysis indicates that over 80% of the recent bill surge is due to expensive gas, while network charges account for 44% of the cap. Policy costs contribute only 7% to the total bill. The cap is forecast to rise further in January 2027, potentially pushing annual bills toward £2,200.
Key points
- In October 2026, UK household energy bills reached their highest level in three years, with the price cap for typical homes hitting £1,723 per year.
- Wholesale costs for electricity and gas make up 44% of the current £1,723 price cap, while network charges account for 24% of bills.
Context
Carbon Brief analyzed data from thinktank Nesta to identify drivers of high energy bills. The UK spent over £60bn on consumer support following the 2022 Russian invasion, but recent gas prices and grid investment costs are the primary factors driving the 2026 surge.
Limitations
Analysis relies on Nesta figures and Ofgem investment plans; wholesale costs are tied to gas prices via marginal pricing. Data covers gas and electricity transmission and distribution but excludes electricity distribution charges. Forecasted 2027 cap rise is based on current trends and may vary.
