Managing business vehicle costs: fuel cards, mileage and fleet expenses in the UK

Keeping business vehicles moving

If your business relies on cars or vans, you already know that the cost of getting from A to B can extend well beyond the vehicle itself. Fuel, mileage, maintenance and everyday administration can all add up, so keeping those expenses organised can make a noticeable difference to your finances. Whether you manage a small team or several vehicles, you can gain a clearer picture of your spending when you bring the different parts of your motoring costs into one manageable system.

Fuel prices also deserve attention when you are planning regular business journeys, as even small changes can have an effect across a busy fleet. GOV.UK’s latest weekly figures show the average UK pump price for petrol reached 168.14p per litre for the week beginning 14 September 2026, while diesel reached 190.72p.

How a fuel card can simplify spending

A fuel card can give you a dedicated way to handle business fuel spending, so you can keep work-related transactions organised across your vehicles or drivers. That can be useful when several employees travel regularly, as you can bring their fuel purchases into a more structured system while reducing the amount of paperwork associated with individual expenses. You can also use transaction information to see where money is going, giving you a more useful view of your running costs.

Allstar offers fuel card solutions for businesses, accepted at 7,700 fuel sites across the UK, representing more than 90% of UK fuel sites. You can also use the Allstar Co-Pilot app to find participating fuel sites around your location, a town, city or postcode, making planning journeys more straightforward when you or your employees are regularly on the road.

Keep business mileage under control

Mileage can become difficult to track when your team is travelling between customers, projects and different work locations, so having accurate records is important. You can use mileage information to understand how much individual vehicles are being used, while your business can also make more informed decisions about expenses and travel policies. If you know how far your vehicles are travelling, you have a much clearer starting point for reviewing fuel consumption and wider running costs.

For the 2026/27 tax year, HMRC’s approved mileage rate for cars and vans is 55p per mile for the first 10,000 business miles, followed by 25p for each additional business mile. The same 55p rate applies to the first 10,000 miles under the simplified mileage rules for self-employed people, with 25p applying after that threshold.

Spend less time dealing with expenses

Vehicle expenses can create a surprising amount of administration, particularly when you have several drivers submitting receipts or claiming mileage. You need to know what was purchased, who made the transaction and whether the spending relates to legitimate business travel, so a clear record can save you considerable time. A more organised payment process also gives you useful information when you review your vehicle costs at the end of each month.

Allstar provides online account management that gives businesses spending visibility, while its platform allows you to set limits, track spending and view reports for individual employees. That means you can look at fuel expenditure in greater detail, so you have more information when reviewing your fleet costs or setting internal spending policies. For a growing business, that visibility can make routine financial administration feel considerably more manageable.

Give drivers clearer spending boundaries

When employees are using business vehicles, clear spending rules can make everyday journeys easier for everyone. You can set expectations around fuel purchases, review transactions regularly and give drivers a straightforward payment method, while your finance team gets a more consistent record of expenditure. That structure can also help you identify unusual spending patterns, so you can investigate them before they become recurring costs.

A dedicated business payment solution can become useful when you want greater control without making everyday driving unnecessarily complicated. Allstar’s online tools let businesses set spending limits and track expenditure, while reports can provide a more detailed view of employee transactions. That combination gives you practical information to work with, so you can review how your vehicles are being used alongside the costs associated with keeping them moving.

Plan for electric vehicles too

Your vehicle costs can also change as your business introduces electric cars or vans, so it makes sense to consider charging alongside traditional fuel. A mixed fleet can create additional administration when some drivers need petrol or diesel while others need access to public or home charging. Bringing those requirements into a more coherent system can help you avoid creating separate processes for every type of vehicle.

Allstar offers Allstar Chargepass and Homecharge,bringing public charging, home charging and traditional fuelling together under one account. That gives businesses a way to consider changing fleet requirements while keeping payment management connected. If you are gradually introducing electric vehicles, having fuel and charging options within the same business-focused approach can make the transition easier to manage.

Make everyday vehicle costs easier to manage

You cannot control every factor affecting business motoring costs, as fuel prices, mileage and vehicle use will naturally fluctuate. You can control how clearly you track those costs, however, so a more structured approach can give you better information when decisions need to be made. A fuel card can help simplify payments, while online reporting can give you greater visibility over transactions and employee spending.

For businesses that depend on regular driving, Allstar offers a practical combination of fuel cards, electric charging options, account-management tools and more. You can use those services to bring more structure to everyday vehicle spending, so your drivers have a straightforward way to pay while your business has clearer information to work with. When vehicle costs are easier to monitor, you can spend less time chasing paperwork and more time running the business.
