Britain’s Transport Minister Keir Mather said on Friday the country’s diesel supply remains “robust” and “resilient” despite record prices and growing concerns over global fuel supplies.
The average price of diesel in the UK reached £2 (nearly $2.7) per liter on Wednesday amid rising pressure on global energy markets linked to the conflict between the US, Israel and Iran.
“I want to reassure people this morning that the UK has got a diverse range of supply when it comes to diesel,” Mather told Sky News.
“We have resilience built into our system for that reason,” he added, saying Britain was working with the US, the International Energy Agency and European partners to sustain diesel flows.
Mather also pointed to the government’s decision to keep fuel duty frozen, saying people “shouldn’t be concerned about shortages because of the inherent resilience that is built into that system.”
The RAC motoring organization said diesel prices reached a record 199.33 pence per liter earlier this week, surpassing the previous record of 199.09 pence set in June 2022 following Russia’s invasion of Ukraine.
Diesel prices have risen by 59 pence per litre, or nearly 40%, since the US-Israel conflict with Iran began at the end of February.
More than half of the UK’s diesel is imported, with 31% of those imports coming from the US.
Separately, G7 leaders have agreed to work “in a coordinated manner” to ease diesel prices. Measures include making production more flexible, releasing strategic reserves of up to 100 million barrels within four months, and avoiding energy restrictions among partner countries.
The developments come after US President Donald Trump said he could ask European countries to release diesel reserves while considering restrictions on US fuel exports.
