Better fuel price data should move fleets beyond searches for the cheapest nearby forecourt towards refuelling decisions based on freshness, confidence and route fit, says Robbie Benardout, founder of PetrolSavings.com.
The cheapest pump price on a screen is not always the cheapest refuelling decision for a fleet. Once detour mileage, driver time, route disruption and the age of the price are considered, a small saving can disappear before the vehicle reaches the forecourt.
The arrival of Fuel Finder gives fleets a better starting point. Under the government scheme, fuel retailers must report pump prices within 30 minutes of any change, giving operators more timely data. For fleets, though, the question is not simply whether more data exists. It is whether that data is being used in a way that reflects how fleet vehicles operate.
A consumer looking at fuel prices may only need to know what is cheapest within a few miles. Fleets have a different calculation. Vehicles are working assets, not casual shoppers. A van on a timed delivery route or a service vehicle booked across several calls cannot always chase the lowest number on a map.
That is where headline savings can mislead. A forecourt that is 4p per litre cheaper may look attractive. On a 60-litre fill, that is £2.40. If reaching that station means extra mileage, a longer stop, a missed break window or a small delay to the next job, that saving can disappear before it is ever made.
The point is not that drivers should ignore cheaper fuel. Far from it. Local price variation can be a clear opportunity for fleets to control a material cost, particularly for van operators and mixed fleets likely to be running petrol and diesel vehicles for years. But the saving has to survive contact with the route.
Price freshness matters for the same reason. A low price is only useful if it is likely to be there when the vehicle arrives. Old or uncertain data can create a wasted stop and a frustrated driver, not a genuine cost reduction.
A fuel price is not just a number in a database. For a fleet, it can become an instruction that sends a vehicle to a specific location.
That frustration has a policy cost. Drivers quickly learn whether central instructions are reliable. If they are repeatedly sent towards changed prices, or stations that do not fit the route, they may stop following the policy consistently. Sometimes their judgement will be sensible. Sometimes it will mean using the most convenient forecourt, whatever the price.
Fleets therefore need to think about fuel price data in the same way they think about other operational data: with confidence levels, not blind certainty. A price with a clear update time, an on-route location and a saving large enough to matter is much more useful than a marginally cheaper price that sits five miles out of the way.
Refuelling policy should reflect this. A policy that simply tells drivers to use the cheapest station is too blunt. It pushes awkward trade-offs onto the driver. A better policy sets thresholds: how far a driver should reasonably divert, when a lower price is worth acting on, and when the value of time and consistency outweighs a few pence per litre.
For multi-stop vans, the better question is not “what is cheapest near the depot?” but “where does this route create a natural refuelling opportunity?” For motorway users, a planned stop before joining may be more cost-effective than a reactive stop at services.
The specifics vary by fleet type, but the underlying principle holds: route context should shape the decision, not just proximity to a low number.
The best fuel decisions will often be unremarkable. A driver fills at a station that is not the cheapest in the county, but has a fresh, credible price, sits close to the route and is materially cheaper than the obvious alternative. That will not create a dramatic saving on a single transaction. Across a fleet, repeated hundreds or thousands of times, it is exactly the sort of disciplined decision that protects margin.
Better price transparency is a step forward. But fleets will benefit most when they treat price as one input, not the whole decision. Price, place, freshness and confidence need to work together. A cheaper number on a screen is only worth acting on when the context around it stacks up.
