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.

Unleaded 95 octane fuel (regular gasoline) prices have been consistently cheaper at supermarkets than fuel stations in the United Kingdom. In March 2024, the gap between both price averages was 3.1 pence per liter, with supermarket prices standing at 142.2 pence per liter.

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.

In September 2022, the average super unleaded fuel price in the United Kingdom was 177.8 pence per liter. This was more than 20 pence lower than the peak of 200 pence per liter recorded in June and July 2022. Super unleaded is a premium gasoline and has been the most expensive motor fuel choice in almost every month. However, in some months of 2022, diesel prices had surged past super unleaded prices.

Retail price of super unleaded fuel for private cars in the United Kingdom is estimated to continuously increase from 124.9 to 147.8 British pence per liter, respectively between 2020 and 2035.

As of September 2022, unleaded 95 octane fuel price stood at 159.8 pence per liter in Northern Ireland and 164.4 pence per liter in London. Prices for unleaded 95 fuel rose across all United Kingdom regions in the early months of 2022. This was a reflection of the price rise for crude oil benchmarks, such as Brent, which serve as the greatest determinant of motor fuel prices. Prices tend to be highest in the capital.

In September 2022, super unleaded fuel prices ranged between 165.6 and 179.3 pence per liter across UK regions. There was a very notable gap between super unleaded prices in Northern Ireland and elsewhere in the country. Figures reached a peak in the summer of 2022 as crude oil benchmarks were carried to 15-year highs.

Super unleaded fuel from supermarkets has sold for around six pence less than the UK average. In September 2022, prices for super unleaded amounted to 171.3 pence per liter at supermarkets, compared with 177.8 pence per liter for the UK average. The price hike noted for 2022 reflects growing energy costs and rising inflation.

In the United Kingdom, the total taxation share in the end consumer price of unleaded 95 octane was 64 percent in 2020. This was a slight decline compared to the previous three years, when taxation made up 65 percent of the end price. The overall price of unleaded 95 octane in the UK plummeted earlier this year, as a result of the coronavirus pandemic and mobility restrictions.

Fuel wholesalers have come up against hugely volatile markets in recent years. The COVID-19 outbreak and subsequent travel restrictions and lockdowns led to a standstill in global transport activity, driving a sharp drop in fuel prices and sales in 2020. Air passenger numbers tanked by 73% in the EU in 2020, according to the European Commission, driving a sharp drop off in demand for jet fuel. OPEC+ manipulates world crude oil prices by adjusting production quotas and collaborating with other producers. OPEC+ worked to cut production in early 2021 to raise prices back to their pre-pandemic level, which gave fuel wholesalers a big boost. Then, Russia’s invasion of Ukraine led to a string of sanctions being placed on Russia by the EU and other Western nations, including the UK. Bans on Russian fuel exports drove prices and wholesalers’ revenue through the roof. For example, according to vehicle insurer RAC, the average price of unleaded in the UK shot up by 23.8% between 2021 and 2022. Over the five years through 2024, fuel wholesalers’ revenue is forecast to fall at a compound annual rate of 3.8% to reach €1.1 trillion, including an expected 5.8% tumble in 2024 as supply cuts push prices up. Rising levels of environmental awareness will encourage fuel wholesalers to stock a growing range of low-carbon fuel options like biofuels and hydrogen (when they become more financially viable) in the future. In many European countries, the push to decarbonise transport is accelerating, with electric vehicles gaining ground on petrol vehicles, having already surpassed the market share of diesel vehicles in terms of new car registrations. The long-term fall in investment in oil and gas will also push up prices. Over the five years through 2029, revenue is anticipated to fall at a compound annual rate of 1.3% to reach €1.2 trillion.

Average price of unleaded gasoline (95 RON) in Great Britain fluctuated. Between 2000 and 2020, figures increased by 0.16 euros per liter, peaking at 1.67 euros per liter in 2012. Prices reached the lowest in 2003, at 1.10 euros per liter. The average price for unleaded gasoline amounted to 1.48 euros in 2020.

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.
