Business Credit Cards for Company Cars: What to Know

10 Sep 2026

If you run a company car, a van, or a small fleet, the chances are you've already got a business credit card sitting in your wallet or your driver's glovebox. They're handy for the odd garage bill, a parking meter that only takes cards, or a motorway toll when you're miles from the office. But business credit cards are often misunderstood, especially when it comes to buying a vehicle outright, and the protection you think you have might not exist at all. Here's a proper look at where they fit, and where they don't.

What actually counts as a business credit card

A business credit card works in the same basic way as a personal one: you spend, you get a statement, and you either clear the balance or carry it forward and pay interest. The difference is who the card is issued to. Personal cards are issued to an individual for their own spending. Business cards are issued to a sole trader, a partnership or a limited company, and the spending sits against the business rather than the individual.

For a sole trader, the line between 'you' and 'your business' is thin, so a business card still tends to affect your personal credit file if things go wrong. For a limited company, the card is a separate legal borrower, though most providers will still ask a director for a personal guarantee before they hand over a credit limit.

Where a business credit card genuinely earns its keep on vehicle costs

Used sensibly, a business card is a decent tool for the smaller, more frequent costs of keeping a vehicle on the road. Things like:

Servicing, an MOT, or a set of tyres at a garage that takes card payment
Parking, tolls, and the London congestion charge or a local clean air zone fee
An insurance excess if you need to claim
Parts and consumables bought on the move

The appeal is simple: one statement, one point of expense tracking, and a bit of breathing room between the purchase and the payment date if you clear the balance in full each month. That last point matters. Business credit cards are a form of borrowing, and if you don't clear the balance, the interest charged on the outstanding amount tends to be considerably higher than you'd pay on a car finance agreement or a business loan, so they suit short-term spending far better than they suit spreading a big cost over time.

Fuel: card or fuel card?

For fuel specifically, plenty of fleets still use a general business credit card because it's simple and accepted everywhere. But if you're running more than a handful of vehicles, a dedicated fuel card is usually worth a look. Fuel cards are built to capture the fuel spend by vehicle and driver, roll everything into one invoice, and in many cases offer discounted pump prices or a fixed weekly rate. A business credit card gives you the merchant name, the date and the total, which is fine for one van but gets messy fast once you're managing a proper fleet.

Business credit cards and buying a used vehicle: the protection gap

This is the bit that catches business owners out. Many people assume that paying for something on a credit card gives them automatic protection if it goes wrong, through what's known as Section 75 of the Consumer Credit Act. That's broadly true for individuals, but it doesn't stretch as far as most people think when a business card is involved.

According to MoneyHelper, you need to use a credit card to pay for something costing more than £100 and up to £30,000 to qualify for cover, and the card company then shares liability with the seller if things go wrong. The catch for businesses is that this protection is built for private consumers. A sole trader using their own name generally still counts as a consumer for this purpose, but a card issued to a limited company typically falls outside the regulated consumer credit rules altogether, which means that Section 75 cover simply isn't there if you use a company card to pay a dealer deposit and the deal later falls apart.

That's exactly why it pays to do your own homework on a used vehicle before you hand over any card details, rather than relying on the payment method to bail you out. Running a free check on our reg lookup tool gives you the car's full MOT history, DVLA details, any outstanding safety recalls and a market valuation in seconds. If you want more depth before committing company money, our vehicle check goes further, revealing whether the car is recorded stolen, has been written off, is still carrying outstanding finance, how many previous keepers it's had, and whether it's been imported, exported or scrapped.

Business credit cards versus finance for buying the vehicle itself

A business credit card is not designed to buy a car or van outright, and trying to use one that way rarely makes financial sense. Credit limits on business cards are usually far too low for a vehicle purchase, and the interest rate on any balance you don't clear is generally much steeper than on a proper vehicle finance agreement. If you're looking to fund the purchase of a company vehicle rather than just its running costs, a dedicated finance product structured around the asset is usually the better route. MotifyMe can introduce you to car finance through an FCA-authorised credit broker, with any agreement subject to status and affordability, so it's worth comparing that route before you consider stretching a credit card limit to cover a purchase it was never really built for.

Keeping vehicle spend under control on a business card

A few habits make a genuine difference if you do use a card for running costs:

Set a rule to clear the balance in full every month wherever possible, so the card is a payment tool rather than a borrowing tool
Give each driver a clear list of what can and can't go on the card, particularly for fuel and parking
Reconcile statements against receipts monthly rather than letting them pile up at year end
Review whether a fuel card or a fleet management account would save time once you're running more than two or three vehicles
Keep the card away from vehicle purchases and use it purely for the smaller day-to-day costs of ownership

The bottom line

Business credit cards have a real, useful role in running a company vehicle: they're quick, they're accepted almost everywhere, and they make it easy to keep track of the small stuff. What they're not built for is buying the vehicle itself or protecting you the way you might expect if a used car purchase goes wrong. Check any car properly before you buy it, keep your card for running costs rather than the purchase price, and look at proper vehicle finance when it's the asset itself you need to fund.

Section 75 thresholds and business credit rules can change, and card providers set their own interest rates, fees and eligibility criteria, so check the current position with MoneyHelper or the FCA register before relying on either for a business purchase.
