A confluence of global conflicts and supply chain disruptions has driven diesel prices in the United Kingdom to near-record levels, significantly impacting motorists, small businesses, and key sectors reliant on the fuel. The sharp rise in costs is linked to damage sustained by oil refineries in Russia and the Middle East, coupled with geopolitical tensions affecting energy production and transport routes.
In recent weeks, British diesel prices have surged by 38%, reaching an average of 196.28 pence per litre, with some forecourts already exceeding £2 per litre—a psychological threshold. This increase follows attacks on Russian refineries, including a recent strike on the Kapotnya facility near Moscow, attributed to Ukrainian forces. The scale of such attacks has reduced Russia’s refinery output by nearly one-third over the past year, contributing to a supply shortage of refined fuels globally.
The situation is further complicated by instability in the Middle East, where the conflict involving Israel and Iran has disrupted production and blockade of the Strait of Hormuz, a critical artery for Gulf oil exports. Middle Eastern refineries, which historically supplied roughly 10% of the world’s fuel, have faced significant damage, limiting their output capacity. Chinese limits on exports of refined products have also tightened supply in international markets, despite the country’s large refining infrastructure.
The shortage affects more than crude oil availability; it centers on refinery capacity to convert crude into essential products like diesel and gas oil. The International Energy Agency notes that the global refining capacity crunch has led to an unusual widening of the “crack spread” — the price gap between crude oil and its refined derivatives — which recently surpassed $100 per barrel in some regions, a historic mark.
The resulting cost pressure has tangible effects across the UK economy. Independent tradespeople, farmers, haulage operators, and other diesel-dependent businesses face sharply higher operating expenses. Jon Barden, a handyman in north London, described diesel costs as consuming about half his daily earnings, forcing him to increase prices despite concerns for his customers’ limited means. Similarly, the Road Haulage Association highlights the direct link between rising diesel prices and increased costs of goods, as virtually all supermarket products rely on diesel-powered transport.
Diesel remains vital in the UK despite a decline in diesel passenger vehicle sales, which have shifted toward petrol, hybrids, and electric models. Diesel fuel use persists in commercial and rural sectors, serving as the backbone for haulage, deliveries, and essential services. Taxi drivers in London, many of whom operate diesel-powered black cabs, are grappling with elevated fuel expenses. Although fare increases were granted earlier this year, ongoing inflation driven by fuel price spikes continues to strain drivers’ incomes.
The UK’s refining capacity has diminished substantially over the past two decades, decreasing from nine operational refineries in the early 2000s to four today. This decline has increased dependence on imported diesel, which now accounts for more than half of the domestic supply. Elizabeth de Jong, chief executive of Fuels Industry UK, stressed that the combination of refinery closures and intensifying geopolitical disruptions underscores the strategic importance of maintaining robust domestic refining infrastructure.
The persistent rise in diesel prices presents broader economic challenges by inflating transportation and logistics costs, thereby contributing to sustained inflationary pressures beyond the direct impact on consumers at the pump. Analysts and industry representatives warn that without mitigation, the strain on businesses and households dependent on diesel could intensify in the coming months.
