Energy bills: What is happening to gas and electricity prices?

Executive summary

Ofgem's latest energy price cap sees typical annual energy bills rise by £60 to £1,723 from October, affecting millions in England, Scotland, and Wales. This increase is primarily driven by higher wholesale gas costs, with further significant rises forecast for the coming winter.

Why it matters

For UK AI infrastructure, rising energy costs present a direct challenge to operational expenses, particularly for energy-intensive data centres. The underlying drivers of these price changes, such as wholesale gas costs and infrastructure investment, indicate a volatile energy market and underscore the long-term importance of stable, affordable electricity supply for continued AI sector growth and competitiveness.

Sector impact

Analysis by AI Energy Intelligence UK

UK electricity demand

The article states that the cost of maintaining and strengthening energy network infrastructure, including power lines and cables, is rising, with a £28bn investment approved to improve the electricity and gas grids. This investment aims to strengthen energy supplies and reduce dependence on gas, which could indirectly support increased electricity demand from sectors like AI by enhancing grid resilience and capacity.

UK energy security

The primary driver for the October price cap increase is higher wholesale gas costs, which have been influenced by geopolitical events. This highlights the UK's ongoing vulnerability to international gas market fluctuations. However, significant investment in grid infrastructure is underway, partly to reduce Britain's dependence on gas and strengthen energy supplies, which signals a long-term strategic effort towards greater energy security.

Businesses

Businesses operating data centres or other energy-intensive AI infrastructure will face higher energy costs due to the increased price cap, impacting operational budgets. The article also mentions a long-term investment in grid infrastructure, partly funded by an additional £108 on bills by 2031, which will contribute to overall energy costs for businesses over time, though it aims to provide a more robust and less gas-dependent supply.

Consumers

Millions of households in England, Scotland, and Wales face an increase of £60 in their typical annual energy bills, reaching £1,723 from October. Most of this increase is due to an 8% rise in gas prices, with further significant rises forecast for the winter. Consumers will also contribute to grid infrastructure upgrades, adding approximately £6 a month to bills from April 2026.

Quotations

"The price rise for October to December was technically 3.6%, Ofgem always rounds the number which is why it publicised the 4% figure."

Long-term implications

The UK energy landscape faces continued volatility driven by wholesale gas prices and geopolitical factors, suggesting ongoing cost pressures. However, substantial long-term investment in electricity and gas grid infrastructure, partially funded by consumer bills, aims to enhance energy security, reduce gas dependence, and strengthen supply reliability for future demand, including from the AI sector.

Frequently asked questions

What is the new typical annual energy bill?

The new typical annual energy bill for England, Scotland, and Wales will be £1,723 from October.

Why are energy bills rising?

Energy bills are rising primarily due to higher wholesale gas costs, which have been pushed up by geopolitical events.

What is happening with standing charges?

Average standing charges for direct debit customers from October to December 2026 will be 54.83p a day for electricity and 29.68p a day for gas. The electricity charge is slightly lower than the previous period, while the gas charge is largely unchanged.

How will grid infrastructure investment affect bills?

A £28bn investment to improve the electricity and gas grids, aimed at strengthening supplies and reducing gas dependence, will add approximately £108 to energy bills by 2031, starting with around £6 a month from April 2026.
