Fleet managers have more information at their fingertips than ever before - the tricky bit is working out what actually matters. Fuel and charging transactions, mileage, routes, vehicle usage and driver trends can all tell you something useful about how your fleet is performing. But staring at a dashboard full of numbers isn't going to save you money on its own. The real value comes from spotting patterns, understanding what’s driving them, and taking action based on what you find.
And there can be real savings on the table. The RAC estimates that fleets could cut fuel costs by up to 15% by using telematics data to tackle things like excessive idling, harsh acceleration and braking, and inefficient route planning.
So, where should you start?
1. Look beyond your total fuel and energy spend
Knowing how much you're spending on fuel and charging is useful, but it doesn't tell you the whole story. Looking at spend by vehicle, driver or journey can start to show where costs are creeping up and, more importantly, why.
For example, if two similar vehicles covering similar routes are using very different amounts of fuel, it's worth digging a little deeper. It could come down to the route, the vehicle itself or the way it's being driven. That's the kind of insight that gives you something practical to act on rather than simply knowing that this month's bill is higher than last month's.
Tools such as bp's Online Account Manager can help fleet managers keep a closer eye on fuel spend, transactions and activity across the fleet, making it easier to spot trends or anything that looks unusual.
2. Check whether you're getting enough from your vehicles
When things are busy, it’s easy to assume every vehicle in your fleet is earning its keep. But the data may tell a different story.
Looking at mileage and vehicle utilisation can help identify vehicles that are sitting around more than expected, as well as those being worked particularly hard. That could lead to something as simple as moving vehicles between teams or routes, or it might help inform bigger decisions about what your fleet needs in the future.
For mixed fleets, it's also worth comparing how petrol, diesel and electric vehicles are being used. Understanding which vehicles work best for different journeys can help you make better use of what you've already got.
3. See what driver trends are telling you
Driver data shouldn't just be about keeping tabs on people. Used well, it can help identify where drivers might benefit from extra support and where small changes could make a difference to both efficiency and safety.
Repeated idling, harsh acceleration and braking or regular detours can all push up costs over time. Instead of looking at one journey in isolation, look for recurring patterns. If the same behaviours keep cropping up, there may be an opportunity to offer useful feedback or rethink a route.
This is where the RAC's findings are particularly interesting. Its 2026 analysis suggests that smarter use of telematics and driver data could help fleets save up to 15% on fuel, showing how seemingly small habits can add up when they're repeated across an entire fleet.
4. Find the miles you don't need to be driving
A route might have worked perfectly well a year ago, but that doesn't mean it's still the best option today. Looking at journey times, mileage and regular stopping points can highlight routes that consistently take longer than expected or add unnecessary miles. You might also find that drivers are regularly going out of their way to find somewhere to refuel or charge.
That’s where better journey planning can help. For EV drivers, the bp Fuel & Charge app can help with day-to-day planning by showing nearby charge points and live availability. The Fuel & Charge card also gives drivers access to more than 3,400 fuel sites and around 53,000 charge points across the UK, giving fleets more options when planning journeys and helping drivers avoid unnecessary detours.
5. Don't overlook transaction data
Regularly reviewing transactions can reveal unusual spending, repeated purchases or differences between vehicles and drivers that are worth a closer look. It’s also a useful opportunity to check whether card settings still reflect how your fleet operates today.
bp’s online tools give fleet managers visibility over card activity and let them manage spending limits and purchase restrictions in one place. Alerts can flag unusual activity too, reducing the need to manually check every transaction.
The key is to use reporting proactively. Rather than waiting until there’s a problem, look for patterns that could point to unnecessary costs or opportunities to tighten up how your fleet operates.
So, what should you do with all that data?
You don’t need to track every number to run a more efficient fleet. In fact, too much data can make it harder to see what really matters. Instead, start with the questions that matter to your business. Where are we spending more than expected? Which vehicles aren't being used enough? Where are drivers regularly losing time? Are the same problems cropping up again and again?
From there, you can focus on the data that helps answer those questions and make changes that have a real impact. Because ultimately, good fleet data isn't about having more numbers. It's about making better decisions with the ones you've already got.
