British drivers are paying the most for diesel in Europe, new data from the RAC found.
On average, a litre of fuel in the UK costs 155p, 5p higher than Ireland and Belgium, the two countries with the second most expensive diesel in the continent.
Luckily for petrol drivers, unleaded fuel is slightly cheaper when compared to the rest of Europe, with a litre costing around 149p, making it the 11th most expensive country.
Breakdown and roadside assistance company RAC said there is “no good reason” for diesel prices to be so high as it struggled to understand why filling stations can’t cut them.
Fuel retailers have been found to operate with margins much higher than the long-term mean, the RAC added, pointing to a lack of competition as a key reason.
"It's important to note that in Northern Ireland, where there is greater competition for fuels in the absence of supermarket dominance, the average price of diesel is just 144.9p - 10p less than the UK average, and petrol is 6p cheaper at 142.4p," the automotive group said.
In 2022, the government introduced a cut to the 5p tax on fuels due to the war in Ukraine sending prices higher.
However, the RAC found that European countries that kept the fuel duty still pay less overall to fill up.
Earlier this month, research by the company found petrol and diesel rose by 10p a litre in 2024, adding £5.50 to the cost of filling up a family car.
The lowest prices for both fuels in 2024 were recorded on 16 January at 139.7p and 147.6p respectively and since then the cost has risen to 149.95p and 157.7p on average.
