UK Fuel Prices Skyrocket as Iran Conflict Disrupts Global Oil Supply
Petrol and diesel costs in the UK have surged dramatically since the onset of the Iran conflict, with new data revealing a widening price gap among suppliers. Supermarkets, traditionally known for offering slightly cheaper fuel, are now leading the market with significantly lower prices, but this advantage comes with challenges such as queues and temporary shortages.
Supermarkets Offer Best Deals Amid Rising Prices
According to the AA, the price difference between supermarkets and other forecourts has increased notably. Before the Middle East conflict began, the gap was 5.4p per litre, but last week, supermarket petrol was an average of 7.6p cheaper, and diesel was 8.8p lower. However, high demand has led to issues like closed pumps and shortages, with Asda warning of temporary supply disruptions and Sainsbury's and Tesco experiencing similar problems over the weekend.
The AA notes that pressure on supermarket fuel supplies tends to occur predictably during weekends and in urban areas, but disruptions are generally not widespread and are resolved quickly.
Impact of Iran Conflict on Fuel Prices
The surge in UK fuel prices is directly linked to supply chain disruptions in the Middle East, particularly Iran's selective blockade of the Strait of Hormuz. This vital waterway handles approximately 20% of the world's oil and natural gas, causing global instability in fuel markets. The RAC Foundation estimates that since the conflict started, motorists have paid an additional £409 million for diesel and £135 million for petrol.
Why Supermarkets Can Offer Lower Prices
Supermarkets benefit from high-volume purchasing and lower operational costs, allowing them to price fuel competitively. Personal finance expert Freddie Winter explains that fuel often serves as a loss leader or near-loss strategy to attract shoppers who then spend more on other items. "Petrol and diesel prices are prominently displayed, making it easy for consumers to compare and for supermarkets to stand out with lower rates," he tells Metro.
This pricing strategy has drawn many drivers to supermarkets, contributing to supply pressures. A similar trend is observed in France, where online maps show that most forecourts with limited or no fuel are supermarket or discount store sites, with 1.6% reporting low supplies and 0.2% completely out.
How to Find the Cheapest Fuel Near You
While supermarkets are a reliable option for cheaper fuel, prices can vary, and they may not always be the cheapest. To secure the best deal in real-time, use online price trackers. The UK government's Fuel Finder scheme, launched in February, requires all petrol stations to report prices, with updates within 30 minutes. Websites like Confused.com, DriveScore, and PetrolPrices.com utilize this data to help consumers compare prices.
Recently, MoneySuperMarket introduced its own tool, allowing users to input their postcode and travel distance to receive an instant list of up-to-date fuel prices. "Small savings add up over time. Saving 5p per litre can mean up to £156 annually for regular drivers," says Alicia Hempsted, Car Insurance Expert at MoneySuperMarket.
Freddie Winter advises drivers to practice economical driving habits, such as gentle acceleration and reduced braking, to further cut costs. "Gamifying fuel efficiency by monitoring miles per gallon can make a significant difference," he adds.
