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.

Free in the UK, including CarPlay. No account, no subscription, no ads.

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.

The price gap +£1.68 40 litres at 171.7p instead of 175.9p
The drive there £0.65 2.6 extra miles, at your car's real mpg
What you keep £1.03 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.

The Channel doesn't change the maths

Plan Leeds to Monaco and back and it prices the whole thing in fuel — 2,141 miles, £572.97 — then tells you to fill at a BP on the way out at 179.9p and a Carrefour on the way home at €2.159, neither of them a mile off your route.

French prices in euros, the total in pounds. One payment of £4.99, not a subscription — and more countries are coming.

The Journey screen planning Leeds to Monaco and back: 2,141.1 miles, a round trip costing £572.97 or about €668.43, filling at BP on the way there and Carrefour at €2.159 on the way back.

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.

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.

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, split per car, with your best-ever saving. The annual projection stays hidden until there's enough history to mean anything — it says so, rather than guessing.

Favourites that tell you when

Pin the forecourts you actually use and get a notification the moment one cuts its price — instead of 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.

How long that price has held

Every grade at a station, the cost of filling your tank there, and how long the price has stood — a forecourt that hasn't moved in three weeks is stable, not stale.

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.

Price alerts

It tells you. You don't go looking.

Follow the forecourts you actually use. Pump Pence watches the feed and lets you know the moment one of them drops its price — so you fill up on the good day instead of finding out afterwards.

An iPhone notification from Pump Pence reading: Cheaper fuel at a station you follow — ASDA is down 2p to 153.7p for unleaded.

Notifications are optional, and there are never any of the other kind.

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 it tells you rather than inventing a figure. And it won't project an annual saving off two fills — in its own words, “anything less would be a guess dressed up as a projection.”

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.
