The United Kingdom has successfully avoided the need for natural gas imports worth an estimated £5.9bn since the outbreak of the Hormuz crisis, new energy analysis reveals. According to comprehensive data published by Carbon Brief, an unprecedented surge in domestic generation from wind and solar farms has insulated the country from the worst shocks of a rapidly escalating global fossil-fuel crunch.

While international wholesale gas prices surge to levels not witnessed since the height of the 2022 European energy crisis, the UK’s green energy sector has expanded dramatically. Output from wind and solar installations has jumped by 14% year-on-year, fundamentally altering the country’s energy landscape and directly dampening the demand for fossil fuels.

This record-breaking clean-power generation has cut the requirement for gas-fired electricity by nearly 10% year-on-year through the first three quarters of 2026. In total, wind and solar technologies have accounted for an unprecedented 41% share of the UK’s overall electricity needs so far in 2026. By comparison, gas-fired power stations have contributed just 25% of the national mix over the same period, illustrating a profound shift away from hydrocarbons in the power sector.

The financial and logistical impact of this green transition has been substantial. Carbon Brief’s modeling shows that the £5.9bn in avoided gas imports since the onset of the US-Iran conflict in February 2026 represents a massive saving for the national economy. To put that figure into perspective, acquiring that volume of gas through alternative means would have required the UK to secure the equivalent of more than 100 additional tanker deliveries of liquefied natural gas (LNG) on fiercely competitive international markets.

During September 2026 alone, monthly import savings reached £1.3bn. This exceptional monthly saving was driven by a powerful combination of record-breaking wind and solar output—surpassing nearly 10 terawatt-hours (TWh)—and sharply rising wholesale gas prices driven by geopolitical instability in the Middle East.

A Decade of Volatility and Surging Market Prices

The current market turmoil compounds years of structural volatility in European energy markets. Wholesale gas prices across the UK have remained persistently elevated ever since Russia severely restricted supplies to Europe in the wake of its 2022 invasion of Ukraine.

Following that geopolitical shock, UK gas prices averaged 90p per therm from 2023 through the end of last year. While lower than the peak of the 2022 crisis, this baseline remained roughly three times higher than the prices recorded in 2019, before the compounding disruptions of the COVID-19 pandemic and the war in Ukraine.

However, the outbreak of war in the Middle East in March 2026 pushed prices even higher. Since the conflict began, gas prices have averaged 134p per therm—nearly four times the pre-crisis levels seen in 2019. The market pressure intensified further heading into autumn, with gas prices averaging 189p per therm during September 2026, marking the highest sustained price point since the global energy crisis four years ago.

Analysts note that UK gas prices are spiking once again due to the seasonal approach of winter, which naturally triggers higher demand for domestic and commercial heating, combined with the ongoing and open-ended nature of the Hormuz crisis. Compounding these pressures, European natural gas storage inventories remain unseasonally low. As a result, European nations are locked in a high-stakes international tug-of-war with Asian buyers to secure the scarce LNG cargoes necessary to maintain adequate heating reserves through the colder months.

The Divergence Between Gas and Electricity Bills

While the large-scale expansion of wind and solar generation has successfully protected the UK power grid from complete exposure to these soaring wholesale costs, the broader economy remains vulnerable. High wholesale gas prices are transmitting directly into household gas bills under the strict price cap regulated by Ofgem.

From 1 October, typical household gas bills are slated to rise by 33% compared to April levels, adding roughly £200 per year to consumer expenses, according to analysis by the energy think tank Nesta. In stark contrast, household electricity bills have barely budged, rising by a mere 4% over the same timeframe.

Andrew Sissons, director for a sustainable future at Nesta, highlighted the changing dynamics of the market in a public statement, noting that the historic link between electricity prices and gas prices has begun to structurally break down thanks to the proliferation of renewables.

The shockwaves from the international fossil-fuel crunch extend far beyond the UK borders. Fossil-fuel importing nations across the globe are grappling with inflated prices for oil, diesel, and other refined fuels. Reports indicate that the European Union has been forced to absorb an extra €100bn in fossil-fuel import costs since the start of the current crisis, with low- and middle-income countries bearing an especially heavy economic burden.

Within the UK, diesel prices have climbed to record highs of around £200 per litre. Conversely, recent analyses underscore the insulating effect of electrification, showing that operating electric vehicles remains up to nine times cheaper than driving petrol or diesel cars.

Political Response and the Push to Decouple Prices

Addressing delegates at the annual Labour Party conference, Energy Secretary Miatta Fahnbulleh emphasized that domestic energy bills remain unacceptably high precisely because the UK economy continues to be dangerously exposed to volatile global fossil-fuel markets.

Prime Minister Andy Burnham echoed these sentiments during his own conference address, pointing to the rapid expansion of renewable infrastructure as the primary mechanism for shielding consumers from international market shocks.

"We are already taking more control of our electricity prices with a massive expansion of home-grown renewables and nuclear," Burnham told party members. He added that he has directed the energy secretary to accelerate efforts to break the direct pricing link between consumer electricity costs and the international gas market in order to drive bills down permanently.
