The UK is Europe’s most expensive country for the sale of diesel fuel next to Sweden. In both countries, diesel fuel costs averaged at 1.32 British pounds per liter. Taxes and duties in the UK account for 80 pence per liter, notably more than in any other European country, with the pre-tax price at merely 52 pence per liter. Diesel prices saw a net increase between early 2015 and early 2020, with a peak of 136.7 pence per liter paid during October 2018.
Supermarkets consistently offered the most competitive prices. In 2019, diesel bought at supermarket affiliated stores was on average three pence cheaper per liter when compared to the UK mean. It is thus unsurprising that supermarkets are also among the leading petrol stations for passenger cars and light commercial vehicles when looking at volumes sold. Of the leading five brands, four are supermarket chains, with Sainsbury coming in first, selling 11,768 kiloliters per annum in forecourts.
