FillUp
Free · UK beta · By 42Analytics
A cheaper fill-up, with the journey included.
A lower pump price can mean a more expensive trip. FillUp compares the estimated cost of the fuel you buy and the journey to get it, so you can see whether travelling further is worthwhile. Find a station nearby or a fuel stop on a journey you already plan to make.
Open FillUp ↗What you can do
Compare the whole trip
Compare your fill-up and the fuel used getting there and back. Enter your fuel economy and how much you want to buy; optionally include a value for your time.
Find fuel along your route
Enter a start and destination to compare stations along the way. See the selected detour on the map and open the journey in Google Maps with the station as a stop.
Include your discounts
Apply an eligible offer or enter your own voucher to see how it changes the comparison. Savings depend on the offer terms and the amount of fuel you buy.
See the evidence
Price dates, when a reading was last observed, and station-detail sources stay visible. Older prices and unconfirmed closure status are clearly flagged.
Clear about what the data can tell you
FillUp uses the official UK Fuel Finder feed. It is an independent 42Analytics project, with no government endorsement. Comparisons are estimates based on reported prices, routing and your inputs. A recent observation means a price was still in the feed; it does not mean the retailer reconfirmed it. Check the displayed dates and station warnings before setting off.

How we built FillUp
From official fuel data to route-aware comparisons: how the updates, calculations and monitoring work, and what the estimates leave out.
