Keyfuels
The UK's leading bunkered diesel card — fixed weekly price, 3,500+ truck sites
Keyfuels is the UK's largest bunkered diesel card and the default choice for HGV operators chasing the lowest pence-per-litre. Instead of paying pump price, Keyfuels customers pay a fixed bunker price set every Sunday, which typically runs 10–15p/L below forecourt diesel — worth £4,000–£12,000 per truck per year on a 100,000-mile annual mileage. The trade-off: bunker sites are HGV-only and don't include motorway service stations, so most operators pair Keyfuels with a branded card.

Who is the Keyfuels card for?
Keyfuels is built for haulage operators, owner-drivers and trunk-route fleets that plan their refuelling around bunker sites. If your trucks run regular routes between depots or distribution centres, you can route them via Keyfuels sites and pocket 10–15p/L vs pump on every fill. It's not the right card for ad-hoc motorway refuelling, sales fleets, or any vehicle running petrol — those need a branded or multi-network card instead.
Keyfuels pricing — how the fixed weekly price works
Every Sunday, Keyfuels publishes the bunker diesel price for the week ahead. That price is locked in for all transactions Monday through Sunday, regardless of what happens at the pump in between. This protects you from mid-week price spikes and makes weekly fuel cost forecasting genuinely accurate. The price is typically 10–15p/L below the national pump average, with bigger savings during periods of pump-price volatility. Card fees start at £0.50 per card per week.
How to apply for a Keyfuels card
Apply through Fuel Card Store and we'll handle the application end-to-end. You'll need company name, registration number, fleet size, estimated monthly diesel litres and bank details for Direct Debit. Keyfuels runs a credit check on the business; established hauliers are typically approved within 48–72 hours. Cards arrive in 5–7 working days. New limited companies without trading history are usually better served by a prepaid card initially (FuelQ Platinum, UK Fuels prepaid).
Keyfuels — frequently asked questions
How much does a Keyfuels card save?
Typically 10–15p per litre vs forecourt diesel. On a 40-tonne truck doing 100,000 miles a year (~36,000L of diesel), that's £3,600–£5,400 saved per truck per year. A 10-truck fleet saves £36,000–£54,000 annually.
Where can I use a Keyfuels card?
At over 3,500 bunkered truck sites across the UK. The network includes all major haulage routes and depot areas. It does NOT include motorway service stations or branded forecourts — for those, pair Keyfuels with a Shell, BP or Allstar card.
Can owner-drivers get a Keyfuels card?
Yes, single-truck owner-operators can apply. You'll need to be a registered limited company or sole trader with sufficient trading history for the credit check. Owner-drivers without established credit usually start on UK Fuels prepaid or FuelQ Platinum and move to Keyfuels later.
What's the difference between Keyfuels and UK Fuels?
Both are owned by DCC plc and share most of the same bunker site network. Keyfuels tends to suit larger fleets with established credit and direct relationships; UK Fuels (sold via Radius) often offers more flexible terms for smaller operators and bundles telematics or EV charging on the same account.
Does Keyfuels cover AdBlue?
Yes — most Keyfuels bunker sites have AdBlue pumps available on the same card, billed on the same weekly invoice. Some sites also sell IBC AdBlue containers on account for fleets that bulk-fill at depot.
