Choosing the best fuel card company in the UK comes down to four things: where your drivers actually refuel, what the card costs once fees and deposits are counted, whether it handles EV charging and non-fuel spend, and how much admin it leaves your finance team. The headline pence-per-litre rate is the least useful number on the page.
The UK fuel card market is set to reach £840 million by 2035, and fleet vehicles already account for 81.2% of the 3.6 million active fuel cards in the country — so the choice matters. This guide compares seven leading UK providers plus fuelGenie as the cheapest supermarket pick, using the metrics that decide whether you actually save money.
Best UK fuel card companies in 2026, at a glance
| If you want… | Best pick | Why |
|---|
| The widest UK network | Allstar | Around 7,600 sites — roughly 90% of UK forecourts |
| Cheapest supermarket fuelling | fuelGenie | No fees; supermarket pump prices (Tesco, Morrisons) |
| Motorway and A-road routes | bp Plus | Built around bp and partner sites on major roads |
| Fixed, predictable weekly pricing | UK Fuels / Esso | A set diesel price each week |
| A familiar brand with EV support | Shell Fleet Solutions | Recognisable network, SME app, integrated EV |
| Help comparing providers | iCompario | Marketplace that shortlists cards for you |
| One card for fuel + EV + tolls + expenses (UK & EU) | Rally | 99% Visa acceptance, app-free receipts, no deposit |
We build Rally, so we are not pretending to be a neutral publisher. That is why this guide gives the network crown to Allstar, the cheapest-supermarket pick to fuelGenie, and the all-in-one category to Rally. The right answer depends on route coverage, fees, EV charging, admin and whether your fleet crosses borders.
Traditional fuel cards vs modern fleet platforms
The market splits into two camps. Legacy cards tie drivers to a brand's forecourts, which can force detours and list-price surcharges. Modern Visa-backed platforms aim for near-universal acceptance and fold EV charging, tolls, parking and expenses into one account.
| Feature | Traditional fuel cards | Modern fleet platforms |
|---|
| Acceptance | Specific brands/networks, often UK-only | ~99% acceptance across UK and EU |
| Spend covered | Usually fuel only | Fuel, EV charging, tolls, parking and more |
| Driver app | Often a dedicated app per provider | App-free receipts via WhatsApp |
| EV charging | Separate card or network | Integrated across 20+ countries |
| Pricing | Pump-price or list-price, variable fees | Transparent, no deposit or credit check |
| Admin | Manual receipts and data entry | Automated capture, direct accounting sync |
The practical difference is hours, not just pennies: consolidating tools and automating receipts saves most teams 10+ hours a month.
Rally — best all-in-one card
Rally is a Visa-backed platform that works at roughly 99% of fuel stations, plus EV chargers, tolls, parking and approved business spend, across the UK and 20+ European countries. Drivers submit receipts over WhatsApp with no app to install; finance gets one invoice, real-time controls, and a direct sync to Xero, QuickBooks and Sage. There is no deposit and no credit check.
Best for: Fleets that want one card for fuel, EV, tolls, parking and expenses — especially across the UK and EU.
Watch out: Pricing is quote-based, and if you only ever buy supermarket petrol in one town, a free card like fuelGenie will be cheaper for that narrow case.

Allstar — widest UK network
Allstar covers around 7,600 sites — roughly 90% of UK forecourts, including supermarkets, and the Allstar One Electric card adds public EV charging for mixed fleets. It is the default when acceptance matters more than anything else.
Best for: UK fleets that prize maximum site acceptance and route flexibility.
Watch out: Pricing is bespoke and account fees apply; the back office stays traditional, and reviews sometimes flag account-management friction.

Shell Fleet Solutions UK
Shell brings a globally recognised brand and access to over 3,600 UK stations (Shell, Esso, Texaco, Gulf). The Shell Fleet App targets SMEs with up to 30 vehicles and same-day setup, while the standard Fuel & EV Card adds access to tens of thousands of UK charge points.
Best for: SMEs whose routes fit the Shell network and want a familiar brand with integrated EV.
Watch out: Best savings sit inside the Shell network, and the SME app has eligibility rules (registered over a year, director as account holder).

bp Plus — best for motorway routes
bp Plus runs across more than 3,400 UK sites — all bp locations plus partners such as Esso, Texaco and Gulf — with strong motorway and A-road coverage, HMRC-compliant invoicing and real-time consumption monitoring.
Best for: Motorway-heavy fleets that want a conventional card with clear controls.
Watch out: EV charging usually means a separate bp pulse arrangement rather than one integrated card.
Website: bp Plus
Esso Card (by WEX Europe)
The Esso Card covers all UK Esso stations plus acceptance at BP and Shell sites, with real-time tracking, spending limits, card blocking and HMRC-ready invoices. Periodic fee holidays make it easy to trial, and a fixed weekly price helps budgeting.
Best for: Diesel-heavy fleets that want broad UK reach and a predictable weekly price.
Watch out: It is fuel-first; confirm EV support by plan, and broader spend lives in other tools.
Website: Esso Card
UK Fuels (Radius)
UK Fuels offers a range of cards — Fuelplus, Fleetone, Truckone — across supermarket and independent sites, with fixed weekly diesel pricing on some, and the Radius One card pairs fuel with tens of thousands of EV charge points. The Velocity portal and e-route planner give granular control.
Best for: UK fleets that want multi-brand choice, route planning and fixed-weekly options.
Watch out: Coverage and surcharges vary by card type, so you must match the right card to your routes.

iCompario (comparison marketplace)
iCompario is not a card but a marketplace that shortlists fuel cards from many providers — Shell, bp, Esso, UK Fuels and more — based on your routes and vehicles. A useful starting point if you would rather not research every provider yourself.
Best for: Buyers who want a guided shortlist before applying.
Watch out: It is owned by Radius, and final pricing comes from the provider you choose, so read the terms before signing.

The cheapest fuel card in the UK
For pure cost, fuelGenie wins: no account, transaction or card fee, accepted at roughly 1,370 supermarket forecourts where pump prices run a few pence below the national average. We cover it in depth in our best small business fuel card guide.
The honest caveat: "cheapest" is fees plus detours plus admin. A free supermarket-only card is the cheapest option for drivers who already fuel at supermarkets, but for fleets that range across motorways and borders, near-universal acceptance (Rally's 99% Visa coverage) usually wins on total cost by keeping drivers on-route and cutting reconciliation work.
Fuel cards for personal use
Most "fuel cards" are business products, not consumer cards. If you are a sole trader or self-employed driver, you qualify for business cards like fuelGenie, Right Fuel Card or Rally (no deposit, no credit check). If you are a private motorist after pump discounts, supermarket loyalty schemes and cashback fuel apps are the realistic route — a business fuel card needs a business behind it.
How to choose the right card
- Map where drivers refuel. Supermarket-only points to fuelGenie; everywhere points to Allstar or Rally.
- Cost the whole thing. Fees, deposits, low-usage penalties and admin hours, not just the pump rate.
- Count the non-fuel spend. EV, tolls, parking and expenses point to an all-in-one like Rally.
- Check the accounting. Insist on VAT-ready invoices and a clean export to your accounts.
- Protect cash flow. Prefer no deposit and no credit check while you grow.
The bottom line
For the widest UK network, choose Allstar. For the cheapest supermarket fuelling, choose fuelGenie. For motorway routes, bp Plus; for a predictable weekly price, Esso or UK Fuels. And if you want to stop juggling fuel, EV charging, tolls, parking and expenses across separate providers — across the UK and Europe — Rally is the all-in-one to benchmark them against, with 99% acceptance, no deposit and receipts handled over WhatsApp.
