The United Kingdom has successfully avoided the necessity for gas imports valued at £5.9bn since the onset of the Hormuz crisis, largely driven by unprecedented levels of renewable energy generation from wind and solar sources, according to comprehensive new analysis published by Carbon Brief.
While international wholesale gas prices are surging to heights not witnessed since the crippling 2022 global energy crisis, the UK power grid has experienced a dramatic expansion of homegrown clean energy. Generation from wind and solar installations has surged by 14% year-on-year, fundamentally altering the country’s immediate fuel demands.
This historic clean-power output has directly suppressed the requirement for gas-fired electricity generation, which has dropped by nearly 10% year-on-year throughout 2026. Cumulatively, wind and solar have accounted for a record-breaking 41% share of the UK’s total electricity requirements so far in 2026, substantially outpacing gas-fired generation, which sits at 25% over the same timeframe.
The financial and logistical scale of these savings is immense. The £5.9bn in avoided gas imports—calculated since the outbreak of conflict between the United States and Iran in February 2026—represents the energy equivalent of more than 100 additional tanker deliveries of liquefied natural gas (LNG). For September 2026 alone, monthly import savings have reached approximately £1.3bn, propelled by nearly 10 terawatt-hours (TWh) of combined wind and solar output intersecting with soaring market prices.
These latest figures update previous analyses released by Carbon Brief earlier in the year, tracking a compounding trend of renewable resilience against foreign supply shocks.
Escalating Gas Prices and Global Market Pressures
The broader macroeconomic environment remains deeply strained. Wholesale gas prices in the UK have stayed structurally elevated ever since Russia curtailed and ultimately cut off pipeline supplies to Europe following its invasion of Ukraine in 2022.
Following that initial shock, UK gas prices averaged 90 pence per therm from 2023 through the end of last year—roughly triple the baseline seen in 2019 prior to the convergence of the Covid-19 pandemic and the Ukraine conflict. However, the outbreak of war in the Middle East in March pushed prices up further, averaging 134 pence per therm, or nearly four times 2019 levels.
By September 2026, average prices climbed to 189 pence per therm, marking the highest sustained monthly average since the peak of the 2022 global energy crisis. Market analysts attribute this latest spike to the seasonal approach of winter, which naturally drives up heating demand, combined with an ongoing lack of resolution to the Hormuz crisis.
Compounding the problem, European natural gas storage inventories remain critically low heading into the colder months. This shortage forces European nations into a fierce international tug-of-war with Asian markets to secure the constrained cargoes of LNG required to maintain domestic heating and industrial operations.
The Divergence Between Gas and Electricity Bills
The impact of these soaring wholesale costs is filtering unevenly through the domestic economy. In the UK, high wholesale gas prices are immediately hitting household heating bills under the regulatory price cap set by energy regulator Ofgem. Conversely, household electricity bills have remained remarkably stable.
Beginning October 1, typical household gas bills are slated to jump 33% higher than they were in April, adding roughly £200 per year to consumer expenses, according to independent analysis from the thinktank Nesta. By stark contrast, typical household electricity bills are projected to rise by only 4% over the same period, heavily cushioned by the massive influx of zero-carbon generation feeding into the national grid.
Commenting on these shifting market dynamics, Andrew Sissons, director for sustainable future at Nesta, noted on social media that the traditional economic coupling between electricity and gas prices has definitively begun to break down.
The vulnerability, however, extends beyond domestic heating. The UK and other fossil-fuel importing nations are absorbing steep cost increases across the entire spectrum of refined hydrocarbons, including oil and diesel. The European Union has reportedly incurred over €100bn in extra fossil-fuel import expenses since the crisis began, with these burdens falling with particular severity on low- and middle-income nations.
Domestically, UK diesel prices have surged to record highs of approximately £2 per litre. This contrasts sharply with recent Carbon Brief analysis showing that driving an electric vehicle remains up to nine times cheaper per mile than operating a comparable petrol or diesel car.
Political Response and the Path Forward
Addressing these challenges at the Labour Party conference, Energy Secretary Miatta Fahnbulleh emphasized that domestic energy bills remain unacceptably high precisely because the nation has spent decades exposed to the volatility of global fossil-fuel markets.
Prime Minister Andy Burnham echoed these sentiments during his conference address, highlighting the rapid expansion of renewables as a vital buffer against international price shocks.
"We are already taking more control of our electricity prices with a massive expansion of home-grown renewables and nuclear," Burnham told delegates. "I have asked Miatta to speed up the breaking of the link between what we pay for power at home and the international gas market, to get bills down."
