Fuel Card Savings & Benefits: 3 UK Business Case Studies
Fuel cards can do much more than provide a convenient way to pay for diesel. For businesses that rely on vehicles, they can help reduce fuel costs, improve visibility over spending, simplify administration and make expenses easier to manage.
At UK Business Buddy, our 2026 year-to-date average Inc VAT saving is currently 11.66ppl compared with the RAC UK average pump price.
That means a business using 1,000 litres of diesel could have saved an average of approximately £116.60 based on our 2026 pricing data.
Below are three business examples showing how fuel cards and better fuel management can deliver benefits beyond the price paid at the pump.
Case Study 1: Red Bull UK – Reducing Mileage and Improving Fuel Control
Case Study 1: Red Bull UK – Reducing Mileage and Improving Fuel Control
Red Bull UK needed greater control over fuel costs across its vehicle operations while also looking for opportunities to reduce unnecessary mileage.
By combining fuel cards with mileage monitoring, the business was able to improve visibility over how vehicles were being used and where fuel costs were being generated.
Reported results included:
• 12% reduction in business mileage within six months
• 15% reduction in cost per mile
• improved VAT reporting and fuel expense administration
The wider benefit was not simply a lower fuel bill. Better data gave the business more information to support decisions around vehicle usage, driver behaviour and operating costs.
Case Study 2: The Hendy Group – Better Oversight of Fleet Fuel Spending
Case Study 2: The Hendy Group – Better Oversight of Fleet Fuel Spending
For businesses operating multiple vehicles, managing fuel expenses can quickly become an administrative burden.
The Hendy Group used fuel cards to provide greater consistency and visibility across its fleet fuel spending.
Instead of relying on individual receipts and fragmented payment records, fuel-card transaction data made it easier to monitor expenditure and understand fuel usage across the business.
Key benefits included:
• easier fuel expense tracking
• improved financial oversight
• simpler budgeting and forecasting
• reduced manual administration
• better visibility over fleet fuel usage
For larger fleets in particular, these operational benefits can be just as valuable as the direct saving made on each litre of diesel.
Case Study 3: Marlowe Fire & Security – Simplifying Fuel Administration
Case Study 3: Marlowe Fire & Security – Simplifying Fuel Administration
Marlowe Fire & Security needed an efficient way to manage fuel expenditure across vehicles operating in different locations.
Fuel cards provided a centralised method of purchasing and recording fuel, helping the business reduce the amount of manual administration associated with individual fuel receipts.
Benefits included:
• consolidated fuel transaction records
• simpler invoicing
• easier VAT administration
• improved control over fuel expenditure
• greater visibility of fleet costs
For businesses with drivers regularly travelling between customer sites, reducing administrative workload can save significant time while providing better financial control.

Fuel Card Benefits Go Beyond the Price Per Litre
Fuel Card Benefits Go Beyond the Price Per Litre
A competitive diesel price is important, but businesses often gain additional value from the way fuel cards simplify fuel management.
These benefits can include:
• consolidated HMRC-compliant fuel invoices
• less reliance on paper receipts
• clearer transaction records
• improved visibility over driver fuel spending
• easier VAT record keeping
• better control over business fuel expenditure
• access to online account and fuel-management tools
For businesses operating several vehicles, having fuel expenditure recorded in one place can significantly reduce administration.
Transparent Weekly Diesel Pricing
Transparent Weekly Diesel Pricing
Fuel-card savings can change as wholesale and pump prices move, which is why we believe customers should be able to see how their fuel-card price performs over time.
UK Business Buddy publishes its weekly diesel price openly online.
Every customer using the same fuel card receives the same weekly price, and our full historical pricing data is available through our interactive diesel price graph.
Customers can compare our fuel-card prices with the RAC UK average pump price and see how pricing has changed over time.
This means you do not have to rely on a headline introductory saving. You can see the actual pricing history for yourself.
Choosing the Right Fuel Card
Choosing the Right Fuel Card
The cheapest headline price is not always the only consideration when selecting a fuel card.
Businesses should also consider:
• where their vehicles regularly travel
• which fuel stations are available on those routes
• the card’s station network
• fuel usage
• payment terms
• account-management tools
• invoicing requirements
Our online application page includes tools, guidance and instructional videos designed to help businesses understand the available options and select a suitable card themselves.
If additional help is required, our team is also available.

Are Diesel Fuel Cards Worth It for UK Businesses?
Fuel cards can help businesses reduce diesel costs, but their value extends beyond a saving at the pump.
Better transaction data, consolidated invoicing, improved fuel-cost visibility and simpler administration can all help businesses manage vehicle expenses more effectively.
UK Business Buddy’s 2026 year-to-date average Inc VAT saving is currently 11.66ppl compared with the RAC UK average pump price, equivalent to an average difference of £116.60 per 1,000 litres.
Because we publish both our current weekly diesel price and our historical pricing data, businesses can monitor those savings over time rather than relying on a one-off headline price.
