The net saving, banded
Green, amber or red on what you'd really keep — with the working shown, the break-even distance, and the extra minutes behind the wheel.
Coming soon for iPhone
Everyone shows you the cheapest pump.
We show you if it's worth the drive.
A forecourt 5 miles away at 3p less isn't a saving until you've paid for the diesel to get there. Pump Pence does that sum — against your car, your tank and the journey you're actually making.

The difference
A cheaper pump isn't a saving yet
It's a saving minus what you burn getting there. Pump Pence does that subtraction — against your car, your tank and the fill you're buying — and tells you how far out of your way it stays worth it.

worth it up to 6.7 miles out of your way
Every other fuel app stops at the first number. That's the one that looks biggest and means least.
Free — not an upgrade
It's on your dashboard, not just your pocket
Pump Pence works with Apple CarPlay, so the decision is on the screen you're already looking at — the stations around you, ranked by what you'd actually save, and directions to the one you pick. No fishing your phone out at a junction.
Rivals charge for this. Ours is included free, in the UK and in France.
Most fuel apps rank forecourts by pence per litre and put a badge on the cheapest one. That's a price list. Pump Pence ranks them by what you'd actually keep — pump saving minus the fuel the detour burns, using your car's real-world mpg and the size of the fill you're buying. Sometimes the answer is "stay where you are", and it says so.
What's inside
Built around one honest number
Everything in the app exists to make that number more accurate, or to make it easier to act on.
Your car, from your number plate
Type your reg and it finds the make, model and engine, then matches tank capacity and real-world mpg from our own curated data. One field instead of six taps.
Ranked by real saving
The list isn't in price order. It's ordered by what each forecourt is worth once the drive is costed — and it tells you that's what it's doing.
Cost a whole journey
Put in where you're going and it prices the trip in fuel — 417 miles Leeds to London and back for £93.92 — then picks where to fill on the way there and on the way home.
Enough left to get there?
Tell it roughly how many miles are left in the tank and it won't send you past the point of no return to save forty pence.
Map view
The same results on a map, where each pin is the price — coloured by whether it beats staying local once the drive is paid for.
Bank what you saved
Log a fill and it keeps a running total, your best-ever saving, and a projection it only shows once it has enough history to be honest about it.
Home, work and favourites
Save the places you fill up near as one-tap chips, pin the forecourts you use, and keep every car you drive in the garage.
Told when the price drops
Pin the forecourts you actually use and get a notification when one of them cuts its price — rather than remembering to go and look.
MOT reminder
It already knows your registration, so it knows when your MOT runs out. A nudge in good time, not a fine and a scramble.
Across the Channel
Taking the car to France? The same maths works there on French pump prices. A one-off £4.99 unlocks it, and more countries are coming.
Litres or budget
Compare what 50 litres costs, or how much fuel £60 buys. Tap ¼, ½ or ¾ full and it works the fill out from your tank size.
Have a look
Five tabs, one question
Real screens from the iPhone app.
How it works
Three taps to an honest answer
Tell it what you drive
Your registration, or make and model. It fills in tank capacity and real-world mpg — both editable, and remembered next time.
Say where you are
Postcode, town, or current location. Add a destination if you're already heading somewhere, and set how far you'd go.
Get the verdict
Pick two forecourts and it tells you what you'd really save, whether the detour pays, and how far out of your way it stays worth it.
Where the numbers come from
No guesses dressed up as data
A fuel app is only worth using if you trust the figure. So here's exactly what's behind it.
8,000+UK forecourts
Dailyprice refreshes
2,300+engine variants
£0in the UK, CarPlay included
Statutory price data
Prices come from the UK government's Fuel Finder open data scheme — the same feed retailers are legally required to report to, refreshed several times a day. Not crowd-sourced, not estimated.
Real-world mpg, not lab mpg
Economy figures come from the Vehicle Certification Agency's published test data with a documented 15% knock-down, because nobody gets the brochure number. You can overwrite it with what your trip computer actually says.
It says when it doesn't know
No tank size API exists in the UK, so where a model can't be matched the app falls back to the picker and tells you. Where it can't cost a drive, it says the figure is pump-only rather than implying it's the real saving.
Nothing to sign up for
No account, no email, no password. Your car, your saved places and your fill history stay in your own browser — they're never sent anywhere.
Questions
The things people ask
When is it out?
It's in the final stages before submission to the App Store. There's no date to promise yet, and we'd rather not invent one.
Does it cost anything?
In the UK, no — free to download and free to use, CarPlay included, with no ads and no account. The only thing you can pay for is French coverage, which is a one-off £4.99 in-app purchase. That's a single payment, not a subscription, and it doesn't unlock anything on the UK side.
Does it work abroad?
France, for now, using French pump prices with the same net-saving maths. It's a one-off £4.99 in-app purchase. More countries are planned — if there's one you'd like next, tell us, because that's how the order gets decided.
Do I need anything special for CarPlay?
Just a car that supports CarPlay. There's nothing to buy and nothing to switch on — plug in or connect wirelessly as you normally would and Pump Pence appears alongside your other apps.
Is there an Android version?
The first release is for iPhone. Android isn't ruled out — if you'd like it, say so. Knowing how many people are asking is genuinely how that gets decided.
How up to date are the prices?
Prices are pulled from the Fuel Finder scheme several times a day, and the app shows you how old the data is. Retailers are only required to report when a price changes, so an older timestamp usually means a stable price rather than stale data. Always check the price on the forecourt before you buy.
Where does my registration go?
It's used to look your vehicle up against the DVLA and DVSA services so the app can find your make, model and engine. The lookup isn't stored on a server, and nothing about your vehicle is shared with anyone else. See the privacy policy for the detail.
Why is the cheapest station not always at the top?
Because the cheapest pump isn't always the best deal. Once the app knows your mpg it ranks by net saving — cheapest station minus the fuel it costs to reach it. It puts a line above the list telling you that's what it's doing.
What about electric vehicles?
Not yet. Per-kWh charging doesn't map cleanly onto pence per litre, and most charging happens at home, where "is it worth the trip" barely applies. The underlying cost-per-mile engine leaves the door open.
My car isn't in the list
Enter the tank size and mpg by hand — the app remembers them, and every calculation works exactly the same. If you'd like a model added, let us know and we'll get it into a future update.
