In recent weeks, motorists across the UK have been feeling the pinch at petrol stations, particularly those operated by major supermarkets. Despite their reputation for offering competitive fuel prices, new data suggests that these retail giants might not be passing on savings from lower wholesale costs to consumers. Let’s take a look at what’s happening with supermarket fuel prices at the moment.
The Current Fuel Landscape
According to recent findings by the RAC, the UK’s largest supermarkets—Asda, Morrisons, Sainsbury’s and Tesco—are currently maintaining profit margins of approximately 15p per litre on both petrol and diesel. This comes at a time when drivers are paying average prices of 160.96p per litre for unleaded petrol and 184.41p for diesel at these outlets.
While supermarket fuel prices remain lower than other retailers by about 2p per litre for petrol and 3p for diesel, the RAC argues that these prices could be significantly reduced if supermarkets were willing to lower their margins.
The Potential for Lower Supermarket Fuel Prices
The RAC’s analysis suggests that if supermarkets were to reduce their average margin to 10p per litre on both fuel types, we could see prices drop to around 152p for petrol and 173p for diesel. That’s a potential saving of 9p per litre on petrol and 11p on diesel—a significant difference that could make a real impact on motorists’ wallets.
Simon Williams, the RAC’s fuel spokesman, expressed concern over the situation: “With many people struggling to put fuel in their cars, it’s very sad to see the biggest fuel retailers taking advantage of their customers by charging far higher prices than they should be.”
Why Focus on Supermarket Fuel Prices?
The RAC’s research centred on supermarket fuel prices due to the dominant position of these retailers in the UK fuel market. Traditionally, these large retailers have sold petrol and diesel at lower prices, thanks to the high volumes they sell. However, the current situation suggests a departure from this practice.

How to Save on Fuel Costs
While we wait for supermarkets to potentially lower their prices, there are several steps you can take to reduce your fuel expenditure:
- Shop around: Don’t assume your local supermarket is the cheapest option. Independent forecourts may offer more competitive prices. Use websites like PetrolPrices.com to compare fuel costs in your area.
- Use a cashback credit card: When paying for supermarket fuel, or fuel anywhere, consider using a cashback credit card. These cards offer a percentage back on your spending, which can add up to significant savings over time. Just be sure to pay off the balance in full each month to avoid interest charges.
- Improve your car’s fuel efficiency: Simple steps like removing roof rack when not in use and keeping your tyres properly inflated can help your car use fuel more efficiently.
- Drive more efficiently: Gradual acceleration and natural braking can help reduce fuel consumption. Avoid sudden starts and stops where possible.
- Consider alternatives: When feasible, consider carpooling, using public transport, cycling or walking. These options not only save money but also benefit the environment.
The Supermarkets’ Response
In response to the RAC’s findings, Asda stated, “Asda is the price leader in the supermarket fuel sector and we remain focussed on providing our customers with the best value at the pumps.”
The British Retail Consortium (BRC), representing major UK retailers including Sainsbury’s, added that “Retailers understand the cost pressures facing motorists and will do everything they can to continue to offer the best value-for-money across their forecourts, passing on cost reductions as they feed through the supply chain.”
The BRC also pointed out that government analysis has shown that the presence of a supermarket can lower fuel prices in the surrounding area.
Supermarket Fuel Prices Going Forward
As fuel prices continue to be a hot topic, it’s clear that supermarket fuel remains a complex issue. While these retailers still offer lower prices compared to many other outlets, the question remains: could they be doing more to help motorists during these challenging economic times?
For now, the best approach for consumers is to stay informed, compare prices and implement fuel-saving strategies where possible. By being savvy about where and how we buy our fuel, we can ensure we’re getting the best value for our money at the pump.
Remember, every penny saved on fuel is money back in your pocket. So next time you’re filling up, take a moment to consider if you’re really getting the best deal on your supermarket fuel.
