fuelfinder.ai vs Supermarket Fuel Apps
One brand's prices, or every brand near you, ranked together.
Supermarket apps are good at what they are designed for: showing you that retailer's own prices, applying that retailer's loyalty scheme, and getting you into that retailer's forecourt. What no supermarket app will ever do is tell you that the independent garage half a mile away is 4p cheaper today.
fuelfinder.ai is brand-neutral by construction. Every forecourt that reports to the UK Government's CMA Pump Watch scheme appears in the same list, ranked by pence per litre, regardless of who owns it. Supermarkets often win that ranking — that is a real pattern, not a slight — but they do not win it everywhere, and on a given day a Costco, a Jet or a local independent may lead your area.
The sensible combination is to use fuelfinder.ai to decide where to go, and your supermarket app to collect whatever points or vouchers apply once you get there. Loyalty value is real and we do not model it; a few pence per litre of points can change the answer when two forecourts are within a penny of each other.
How It Works
- Step 1: Search a postcode — No account, no app install, no email required first.
- Step 2: Compare every brand — Supermarkets, branded majors and independents in one ranked list — Supermarket apps such as those from the major grocers show prices at that retailer's own forecourts.
- Step 3: Navigate and fill — Hand off to your usual maps app with the forecourt already set.

Frequently Asked Questions
Are supermarkets always the cheapest fuel?
Usually but not always. Supermarket forecourts typically sit several pence below the branded majors, but warehouse clubs, some independents and price wars between neighbouring sites regularly change the local ranking. That is exactly what the live list on this site is for.
Does fuelfinder.ai account for loyalty points?
No. Rankings are pure pence per litre. If a scheme is worth a meaningful amount to you, factor it in yourself when two forecourts are close on price.
Is supermarket fuel lower quality?
No. All UK petrol and diesel must meet the same British and European standards. Branded fuels add their own detergent packages, which is a genuine difference in additives, not in the base fuel.
Which supermarkets does fuelfinder.ai cover?
All of them that report to the Government scheme, alongside the branded majors and independents. Each retailer also has its own page on this site if you want to track one brand specifically.
