A dataset of average pence per litre and per gallon petrol and diesel fuel prices in the UK regions including England, Scotland, Wales, and Northern Ireland.

On June 16, 2025, the price of ultra-low sulfur unleaded petrol (gasoline) in the United Kingdom averaged 132.33 pence per liter. This compared to 139.03 pence per liter for diesel. Diesel prices were consistently higher than petrol/gasoline prices throughout this period, although the margin varied. Reasons for such differences in pricing lie in the refining process and molecular makeup of the products, with diesel requiring more complex refining processes and being an overall heavier liquid. As motor fuel pricing in the UK is not regulated by a monitoring body, there may also be notable differences in prices between retailers and regions. Supermarkets provide lowest fuel prices in the UK In the UK, much of the motor fuel is sold through supermarkets. Large supermarkets, or hypermarkets, account for more than 40 percent of all motor fuel sales in the country. The reason for their popularity often lies in the fact that they offer lower average prices. In the last four years, regular petrol/gasoline sold at supermarkets was up to six pence per liter cheaper than the national average. How UK fuel prices compare to the rest of the world Tied as they are to crude oil prices, motor fuels are generally cheapest in major producing countries, such as Iran, Venezuela, and Russia. In Europe, costs of importing the raw or finished products, in addition to taxes and levies, may hike up pump prices significantly. The UK is often among the countries with the highest petrol/gasoline prices, alongside other large European car markets such as France and Germany.

The price of unleaded 95 octane fuel in the United Kingdom has increased significantly in 2022. In September 2022, prices reached 165.3 pence per liter. This was a decrease compared to three months prior when they had climbed to a new high. Unleaded 95 octane is the most commonly used fuel in the UK. Unlike super unleaded, which is mostly used in high performance vehicles, it is suitable for most petrol engines. It is also the cheapest fuel option, when compared to diesel fuel prices.Supermarket vs. UK averageWhen comparing prices, supermarkets are consistently the cheapest option when refueling. The gap between the two has varied, but in 2022 it has closed to just two pence per liter. In 2021, Tesco had the largest market share of motor fuel sold in the UK, at nearly 16 percent. The combined market share of Tesco, Sainsbury’s, Morrisons and Asda amounted to 43.2 percent, which is unsurprising as supermarkets offer the cheapest prices. Petrol station numbersAlthough supermarkets have a large market share of the volume of petrol sold, it is major oil and gas companies that operate the greatest number of petrol stations. By the end of 2021, the British multinational oil and gas firm BP owned 1,218 sites across the country. The combined number of petrol stations of BP, Esso and Shell amounted to nearly 43 percent of all UK outlets. In comparison, Tesco, Sainsbury’s, Morrisons and Asda operated less than 20 percent.
