Fuel Prices & Forecasts Price Direction

When will fuel prices go down in the UK?

Q: When will fuel prices go down in the UK?

There is no confirmed date for UK fuel prices to fall. Pump prices are driven by global crude oil costs, the sterling-dollar exchange rate, fixed fuel duty of 52.95p per litre, and retailer margins — all of which can move in either direction. The most reliable way to pay less today is to compare live prices at stations near you, where the gap between cheapest and most expensive can be 8–12p per litre.

There is no fixed date when UK fuel prices will fall — they are driven by global crude oil markets, sterling exchange rates, fuel duty, and retailer margins, all of which change continuously. What is predictable is that prices vary significantly between stations right now, and comparing before you fill up is the fastest way to pay less today.

What Drives UK Pump Prices

Crude oil is the biggest factor: Around 40–50% of what you pay at the pump reflects the wholesale cost of crude oil, priced in US dollars. When oil rises or sterling weakens, pump prices follow within days. 5

Fuel duty is fixed by government: Fuel duty is currently 52.95p per litre for both petrol and diesel, frozen at that level since 2011. A duty change requires a Budget decision and gives no short-term relief without government action. 3

Retailer margins add to the cost: The CMA found that retailer margins widened significantly after 2021 and have not fully returned to historical norms, meaning pump prices have not always fallen as quickly as wholesale costs. 4

What the Data Shows About Recent Trends

Prices fluctuate weekly: DESNZ publishes weekly average pump prices, and year-on-year data shows petrol and diesel have both risen and fallen by 20p+ per litre within a single year depending on oil market conditions. 2

No reliable long-term forecast exists: Fuel price predictions depend on geopolitical events, OPEC supply decisions, and currency movements — none of which can be forecast with confidence over months. 5

Supermarkets are consistently cheaper: Even when average prices are high, supermarket stations typically undercut branded forecourts by 3–8p per litre. That gap is consistent regardless of the direction of the market. 1

How to Pay Less Without Waiting for Prices to Drop

The spread between stations is significant: In any given town, prices at different stations can vary by 8–12p per litre. Filling a 50-litre tank at the cheapest local station rather than the most expensive saves up to £6 per visit. 1

Supermarkets lead on price: Tesco, Asda, Morrisons, and Sainsbury's consistently offer the lowest pump prices. Checking which is cheapest near you before a journey takes seconds. 1
