On September 8, 2025, the price of ultra-low sulfur unleaded petrol (gasoline) in the United Kingdom averaged 133.72 pence per liter. This compared to 141.58 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.

Hong Kong has some of the highest diesel prices in the world. As of August 4, 2025, drivers in Hong Kong paid an average of 3.49 U.S. dollars per liter of automotive diesel. This was more than three times the amount paid by drivers in Mainland China. Lower prices are often linked to substantial domestic crude oil production and government subsidies, as is the case in countries such as Venezuela, Iran, and the United States.

Diesel prices in the United Kingdom rose to more than *** pence per liter in early 2024. The March national average was ***** pence per liter, compared with a price of ***** pence per liter for diesel sold at supermarkets. Hypermarkets dominate motor fuel sales Hypermarkets such as Sainsbury's, Asda, and Tesco have the greatest market share of motor fuel sold in the UK. In 2023, roughly ** percent of all motor fuels were sold at hypermarkets. Diesel more expensive than regular gasoline Although gasoline and diesel are both refined petroleum products, their refining process differs, thus also impacting manufacturing and retail prices. Diesel sold in the UK is required to have an ultra-low sulfur content and also contain a biodiesel component of seven percent. The extra steps required in the production process make diesel a more expensive commodity than gasoline, which trades around ** pence lower.

Fuel wholesalers' revenue is hugely influenced by trends in the world price of oil. OPEC+ manipulates oil prices by controlling the global oil supply, adjusting production quotas, communicating strategically and collaborating with other major oil producers. Plummeting demand for fuel during the COVID-19 outbreak led to historically low oil prices over 2020-21, causing a sharp dip in revenue and profit. However, cuts to production by OPEC+ led to prices recovering to pre-pandemic levels in February 2021. Oil prices surged to a 14-year high in March 2022 amid supply chain disruptions following key oil exporter Russia's invasion of Ukraine, leading to petrol prices surpassing 180p per litre for the first time. As a result, fuel wholesalers’ revenue surged in 2021-22 and 2022-23. In 2023-24, wholesale prices remained inflated on pre-conflict levels, although they were significantly lower than their peak in June 2022. In 2024-25, prices have returned to pre-conflict levels, driving an expected 0.2% boost in revenue. The industry faces increasing competition from renewable energy sources and the robust growth in alternatively fuelled vehicles (AFVs), as the government has encouraged the purchase of AFVs through government subsidies since 2011. Fuel duty was frozen for the 15th consecutive year in the October 2024 Budget. However, energy consumption in the UK has dipped as technology has become increasingly fuel-efficient. Still, over the five years through 2024-25, revenue is anticipated to grow at a compound annual rate of 0.5% to reach £71.5 billion. Fuel prices will inevitably continue to be dictated by OPEC+ over the coming years. However, geopolitical volatility will threaten this alliance. The prospective ban on new petrol and diesel vehicle sales — part of a wider government policy to target net-zero emissions by 2050 — also threatens future fuel sales. Increasingly stringent environmental regulations will constrain fuel demand. Over the five years through 2029-30, revenue is expected to edge upwards at a compound annual rate of 0.8% to £74.4 billion.

The price for diesel fuel from supermarkets in the United Kingdom stood at 179.3 pence per liter in September 2022, which was around two pence lower than the UK average. It was the second consecutive month that prices had decreased, falling from a peak of 195.6 pence per liter in July 2022 - when crude oil prices (the most important determinant for motor fuel prices) reached 15-year highs. Northern Ireland is the UK region with the lowest diesel fuel prices. It was the only region which had diesel prices below 180 pence per liter in the month of September.

The 2025 annual OPEC basket price stood at ***** U.S. dollars per barrel as of July. This would be lower than the 2024 average, which amounted to ***** U.S. dollars. The abbreviation OPEC stands for Organization of the Petroleum Exporting Countries and includes Algeria, Angola, Congo, Equatorial Guinea, Gabon, Iraq, Iran, Kuwait, Libya, Nigeria, Saudi Arabia, Venezuela, and the United Arab Emirates. The aim of the OPEC is to coordinate the oil policies of its member states. It was founded in 1960 in Baghdad, Iraq. The OPEC Reference Basket The OPEC crude oil price is defined by the price of the so-called OPEC (Reference) basket. This basket is an average of prices of the various petroleum blends that are produced by the OPEC members. Some of these oil blends are, for example: Saharan Blend from Algeria, Basra Light from Iraq, Arab Light from Saudi Arabia, BCF 17 from Venezuela, et cetera. By increasing and decreasing its oil production, OPEC tries to keep the price between a given maxima and minima. Benchmark crude oil The OPEC basket is one of the most important benchmarks for crude oil prices worldwide. Other significant benchmarks are UK Brent, West Texas Intermediate (WTI), and Dubai Crude (Fateh). Because there are many types and grades of oil, such benchmarks are indispensable for referencing them on the global oil market. The 2025 fall in prices was the result of weakened demand outlooks exacerbated by extensive U.S. trade tariffs.
