Getting a Fuel Card for Your Small Business Fleet

Many small businesses assume fuel cards only make sense once a fleet gets bigger.

In practice, they can be even more useful when time is tight, every pound matters and there is no spare admin team to lean on. For smaller fleets, the right card helps you keep spending under control and gives you one less task to chase later.

What counts as a small fleet?

A small fleet, sometimes called a mini fleet, usually has between 1 and 20 vehicles, although there is no formal industry definition. It might be a few vans, a handful of company cars or a mixed group of vehicles used by employees who drive for business. Whatever the setup, the challenge is the same: control fuel spend, cut admin and keep drivers from being out of pocket, and a clearer picture of where spend goes.

How does a fuel card work for small businesses?

A fuel card for small businesses is simple. Drivers fill up at approved stations and pay with the card instead of cash or a personal card. The cost is billed directly to the business, so there are no upfront payments, no expense claims and no chasing receipts.

At the end of each billing period, you receive a single HMRC-compliant invoice covering all transactions, making VAT reclaim, for eligible businesses, straightforward and keeping your records accurate. Drivers can pay using Chip and PIN, swipe or contactless, depending on the card setup.

Allstar cards can also be used to pay at the pump, opening up even more stations and letting drivers refuel out of hours without going inside. Once the transaction is complete, payment is taken directly from the named business account. There is no need for employees to use personal funds, and no risk of fuel costs getting mixed up with personal spending, keeping your accounts easy to reconcile from day one.

What is the best fuel card for small businesses?

The best fuel card for a small business depends on how and where your drivers operate. There is no single right answer, but there are a few things worth checking before you choose the right one:

Wide network coverage: Your drivers should not have to go out of their way to find a compatible station. Allstar's network covers 90% of UK fuel stations, including supermarkets, motorway services and local chains, so there is usually a site nearby when drivers need it.

Competitive pricing: Look for a card that offers genuine savings at the pump. Allstar's Discount Diesel network lets you save up to 8p on every litre of diesel purchased across 1,600+ sites.* For smaller fleets where every litre counts, those savings could add up quickly.

Supermarket access: If low cost is the priority, the Allstar Supermarket+ card limits drivers to supermarket forecourts where fuel prices can be among some of the cheapest available. Use our site locator to check coverage in your area.

Spending controls: The ability to set limits by card, driver or vehicle helps prevent unauthorised spending and helps reduce the risk of unexpected purchases, while keeping spend predictable.

Simple account management: Visibility of all transactions through Allstar Online means you always know what is being spent and by whom, without waiting for end-of-month statements.

Key benefits of a fuel card for small businesses

Better cashflow: Without a fuel card, many small businesses rely on a pay-and-reclaim system where employees pay for fuel themselves and submit expenses later. That creates cashflow uncertainty; you may not know what you owe until weeks after the fact, especially if claims are submitted late. A fuel card helps remove that pressure. Costs are billed directly to the business on a defined schedule.

Less admin: Fewer receipts to manage, fewer expense forms to process and less manual reconciliation. Everything appears on one invoice, giving more time to focus on the work that keeps the business moving.

Control over what drivers spend: Cards can be restricted to specific fuel types, oil or AdBlue and specific spending limits can be set. Drivers only buy what they are authorised to buy, helping keep fleet spend in check without extra admin every month.

More than just fuel: Many cards cover other vehicle-related expenses such as toll fees, car washing and oil changes, bringing more of your vehicle costs into one place. Find out more about the benefits of fuel cards for fleets of all sizes, too.

Is a fuel card worth it for a small business?

This is a question many small business owners ask before making the switch. The short answer is yes, and often more so than for larger fleets.

Larger businesses have dedicated finance teams to handle expense reconciliation. Small business owners typically do not. Every hour spent chasing receipts, processing claims or manually reconciling fuel spend is time taken away from running the business. Our research of 300 UK SMB owners and directors who manage 4-20 vehicles revealed that nearly 48% spend 4-6 hours per month resolving fuel and EV charging payment admin.

A fuel card could significantly reduce that burden. Everything is consolidated onto one invoice, making reconciliation much simpler.

There is also the VAT angle. Every business owner will know that sinking feeling when an employee hands in crumpled, barely legible receipts, or worse, has lost them entirely. With a fuel card, all transactions are consolidated onto one HMRC-compliant invoice, helping eligible businesses reduce the risk of lost VAT and end-of-month uncertainty.

Do employees pay tax when using a company fuel card?

This is worth understanding before you set up a fuel card scheme. If employees use a company card to pay for private fuel, including commuting or personal journeys, this is treated as a taxable benefit. Both the employee and the business may face Benefit in Kind tax as a result.

The simplest way to avoid this is to ensure employees pay back the cost of any private fuel using the Government's Advisory Fuel Rates. HMRC also provides an online car fuel benefit calculator to help work out any liability.

It is also worth noting that businesses are subject to Class 1A National Insurance on the value of any fuel benefit provided to employees. The simplest way to avoid this is to ensure your fuel card is used strictly for business mileage and that users promptly reimburse any private fuel costs using the Advisory Fuel Rates (AFRs).
