From 2000 to 2020, over 35 percent of UK petrol stations closed, although the rate at which numbers decreased had slowed by 2010. Figures fell to their lowest point by late 2020, when only 8,380 sites were operational or in development. The independent distributor Certas Energy saw the most petrol station closures of any brand, with 21 stations being made obsolete between 2019 and 2020. By comparison, Go had opened 27 new petrol stations, more than any other brand.
The UK is the most expensive country for the diesel fuel sales in Europe next to Sweden. In both countries, diesel fuel costs averaged around 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. The average UK diesel price saw a net increase in the last five years, reaching 121.8 British pence per liter in January 2021.
Supermarkets consistently offered the most competitive prices. In 2020, diesel bought at supermarket affiliated stores was on average four pence cheaper per liter when compared to the UK mean. It is thus unsurprising that supermarkets are also among the leading UK petrol station brands when looking at fuel sales for passenger cars and light commercial vehicles. Of the leading five brands, four are supermarket chains, with Sainsbury coming in first, having sold 11,781 kiloliters per forecourt in 2020.
