Diesel prices have reached a record high, with the average cost of a litre now standing at 199.18p as of Monday (September 28), according to new data compiled by the RAC.
This surpasses the previous record of 199.09p, set in June 2022, and marks a rise of 56.8p since the start of the US-Iran war on February 28 this year.
Cost of filling up a family car
The RAC says the cost of filling up an average family car is now almost £110, which is £31 more than it was at the start of the US-Iran conflict.
Diesel prices have climbed steadily in recent weeks due to the impact on global supplies from the ongoing conflict between Russia and Ukraine, and from renewed hostilities in the Middle East.
Russian exports of diesel have dropped sharply after many of the country’s oil refineries were targeted by Ukraine, with a key facility near Moscow damaged earlier this month as part of a huge drone operation.
Global supply pressures
This has led to extra demand for fuel from other diesel-exporting countries, causing wholesale prices to rise.
Meanwhile, the ongoing war between the US and Iran is continuing to disrupt the global trade in refined oil and other petroleum materials, with Iran’s effective blockade of the Strait of Hormuz limiting the production and supply of fuel needed by consumers.
The RAC data is based on the average price of diesel at a range of supermarkets, motorway service stations and independent retailers.
Petrol prices also climbing
The cost of unleaded petrol has also been climbing in recent weeks and currently stands at an average of 174.13p per litre, up by 41.3p since the start of the US-Iran war.
RAC head of policy Simon Williams said: “The average price of a litre of diesel has now reached the highest level in UK history, in what will be a financial blow to households and businesses that use their vehicles regularly.
“The cost of filling up an average family car is now almost £110, £31 more than it was at the start of the US-Iran conflict.
“This spells pain not only at the pumps for drivers, but for everyone who buys goods or services that rely on diesel lorries and vans; undoubtedly these increased costs will be passed on to consumers.
“Only a sustained lower oil price – over several weeks, not days – will lead to cheaper prices at the pumps.”
Vehicle numbers on UK roads
A total of 15.1 million diesel-fuelled vehicles were licensed to be on UK roads at the end of June this year, down from 15.7 million 12 months earlier, according to the latest figures from the Department for Transport.
There were 9.8 million diesel cars, down year on year from 10.4 million. Some 20.4 million petrol vehicles were licensed to be on roads this June, including 18.8 million cars.
