Energy Bills in Great Britain to Jump £276 a Year from January 2026

Energy bills in Great Britain are forecast to jump by £276 a year from January, pushing the typical household bill to £1,999, according to Cornwall Insight. The 16% rise in the price cap would be the biggest quarterly increase since January 2023.

Why Energy Bills Are Rising

The forecast increase is driven by a surge in wholesale gas prices, which have reached three-year highs due to ongoing tensions in the Middle East. The government’s energy price cap, which limits how much suppliers can charge per unit of gas and electricity, is set to rise from January, affecting millions of households.

Cornwall Insight’s latest prediction is significantly higher than its previous forecast of a 9% rise. Analysts warn that the impact will be felt hardest during the coldest months of winter, when energy consumption typically peaks.

Impact on Households

For a typical dual-fuel household, the increase means an extra £23 per month on energy costs. This comes on top of a 4% rise in the price cap from October, which already pushed bills to their highest level in three years.

Craig Lowrey, principal consultant at Cornwall Insight, said: “These prices are going to hit households hard. January is already a difficult month for many, with cold weather and bank balances still recovering from Christmas, and now they face the biggest price cap rise we’ve seen in four years.”

Simone Rossi, chief executive of EDF Energy, warned that the UK is “walking into a second energy crisis.” The combination of high wholesale prices and a rising price cap is putting unprecedented pressure on household finances.

How to Prepare for Higher Energy Bills

With bills set to rise, households can take steps to mitigate the impact. Energy efficiency measures, such as insulating lofts and draught-proofing, can reduce consumption. Switching to a fixed-rate tariff may also offer protection if prices continue to climb, though it’s essential to compare offers carefully.

Government support schemes, such as the Warm Home Discount and Winter Fuel Payment, provide targeted help for vulnerable households. Checking eligibility and applying early can make a significant difference.

• Check your eligibility for government support schemes like the Warm Home Discount.
• Improve energy efficiency by insulating your home and using smart thermostats.
• Compare fixed-rate tariffs to lock in current prices before January.
• Reduce standby power by unplugging devices when not in use.
• Monitor usage with a smart meter to identify savings.

Comparing Energy Price Forecasts

What Experts Say

Analysts attribute the sharp rise to geopolitical instability and its effect on global gas markets. The UK’s reliance on imported gas makes it particularly vulnerable to price shocks. While the government has intervened with the price cap, it only limits unit rates, not the total bill, which depends on usage.

Consumer groups are calling for more targeted support, especially for low-income households and pensioners. The energy crisis of 2022-2023 led to a significant increase in fuel poverty, and charities warn that another spike could push more families into debt.
