Fuel Cards
Single-brand or multi-network fuel card?
A single-brand card usually gives the better price per litre. A multi-network card gives you somewhere to fill up. Which matters more depends entirely on your routes.
Fuel cards fall broadly into two camps. Single-brand cards are issued by one fuel supplier and work at that brand's sites. Multi-network cards are issued by an intermediary and work across many brands, including supermarkets and truck stops.
The trade-off is consistent: concentration buys you a better rate, breadth buys you coverage. The right choice comes from where your vehicles actually stop, not from the brochure.
Side by side
| Single-brand | Multi-network | |
|---|---|---|
| Price per litre | Usually better | Usually slightly worse |
| Site coverage | That brand only | Wide, often thousands of sites |
| Risk of a detour | Higher | Lower |
| Supermarket access | Rarely | Often |
| Truck stop / bunkered access | Depends on the brand | Often included |
| Invoicing | One supplier | One consolidated invoice |
| Best for | Predictable routes near that brand | Mixed or unpredictable routes |
Do the route analysis first
Pull three months of fuel receipts and map where your drivers actually fill up — not where you assume they do. Then check each card's site list against those locations, and against the roads between them.
A card saving four pence a litre at sites your drivers pass twice a month is worth less than a card saving one penny everywhere they already stop. Detours cost fuel and paid driver time, and both are usually left out of the sales comparison.
Where single-brand wins
Predictable routes. A fleet that runs the same corridors, or is based near a strong cluster of one brand's sites, can take the better rate without the coverage penalty.
It also suits operations that already fuel at a depot or a preferred site by policy, where the card is really about invoicing and control rather than finding fuel.
Where multi-network wins
Anything unpredictable — reactive service work, national distribution, drivers covering wide territories. The value is not needing to think about it.
It also suits mixed fleets. Cars and vans do well on wide forecourt and supermarket coverage; HGVs need truck stops with the right access. A multi-network card can cover both, where a single brand rarely does.
Two cards is a legitimate answer
Plenty of fleets run a single-brand card for the bulk of predictable fuelling and a multi-network card as backup for everything else. You get the better rate where volume is concentrated and coverage where it is not.
The cost is a second account and a second invoice, which is minor. Ask each provider whether they mind — most do not, because they would rather have part of your volume than none.
The short answer
Predictable routes with a strong cluster of one brand: single-brand, and take the better rate.
Unpredictable routes, national coverage, or a mixed car-and-HGV fleet: multi-network.
High volume with a clear core route: consider both, and stop treating it as one choice.

Common questions
Is a single-brand card always cheaper?
Usually on the pence per litre, but not once detours are counted. Price it against your actual fuelling locations rather than the headline rate.
Can I have more than one fuel card?
Yes, and mixed fleets often do. There is no obligation to put all your volume on one account.
Do multi-network cards work at supermarkets?
Many do, which matters for car and van fleets where supermarket fuel is often already the cheapest available.
How do I compare coverage properly?
Map three months of real fuelling locations, then check each network's sites against them and against your routes. Total site count nationally tells you nothing.

Fuel Cards
A fuel card is sold on a saving per litre. Whether that saving exists depends entirely on which pricing model you are on and where your drivers actually fill up.
