Compare Diesel Prices Now →Whether you drive a diesel car, van, or HGV, fuel costs add up fast. Tanki shows you the cheapest diesel within your chosen radius, sorted by price so you always know where to fill up for less.
With diesel often 8-12p more expensive per litre than petrol, finding a competitive price matters even more. On a 70-litre tank, a 5p difference saves you £3.50 every fill-up — that's over £180 a year if you fill up weekly.
Standard diesel containing up to 7% biodiesel (FAME). Available at every UK station and suitable for all diesel vehicles.
Enhanced diesel with cleaning additives (BP Ultimate, Shell V-Power Diesel). Typically 12-18p more per litre than standard.
Retailers must report price changes within 30 minutes. Tanki always shows the latest available price.
Sort by price or distance. Perfect for delivery drivers and fleet managers looking to reduce fuel costs.
Asda, Tesco, Sainsbury's, and Morrisons are consistently the cheapest for diesel. Use Tanki to see which supermarket near you has the best price today.
If you're a delivery driver or regularly drive long distances, plan your refuelling around cheaper stations on your route rather than stopping wherever's convenient.
Premium diesel (like Shell V-Power or BP Ultimate) costs significantly more but most modern diesel engines run perfectly well on standard B7. Check your vehicle manual — unless it specifically recommends premium, you're paying extra for minimal benefit.
Rather than running near-empty and filling up wherever's closest, top up when you pass a cheap station. Tanki makes this easy by showing you nearby prices at a glance.
Diesel prices in the UK are influenced by the wholesale cost of crude oil, refinery margins, fuel duty (currently 52.95p per litre), and 20% VAT on the total. The gap between petrol and diesel prices fluctuates based on global supply and demand for each product.
All prices on Tanki come from the GOV.UK Fuel Finder service, with fallback data sourced directly from retailers like Asda and Esso who haven't yet submitted to the government API.
