Some UK fuel stations change pump prices eight times a day

A handful of UK fuel stations are changing their unleaded pump prices as many as eight times within a single 72-hour period, according to official UK government fuel price data, meaning the price you saw on the way to work could be very different by the time you fill up on the way home.

Most forecourts in Britain update their prices once a day and leave them there. However, official UK government fuel price data covering the 72 hours to the morning of 18 July shows that at least six stations moved their unleaded price three or more times in that window. A BP station in Hull changed its price eight times, swinging between 159.9p and 170.9p a litre, which is a difference of 11p or roughly 50p on a typical 45-litre fill. A Shell station in Goole also recorded eight price changes over the same period, moving between 150.9p and 154.9p a litre. Two further BP stations, one in Cottingham and one in a different part of Hull, each changed their price seven times.

For everyday drivers, this matters because a 10p-per-litre swing across a full tank adds up to around £4.50 more or less than you might expect to pay. If you regularly use one of the stations that adjusts prices frequently, filling up at the wrong hour could cost you noticeably more than filling up a few hours earlier or later. The data does not yet point to a clear pattern of when prices tend to be lowest at these particular forecourts, but the swings recorded suggest prices can move at almost any hour, including late at night and in the early hours of the morning.

The practical takeaway is straightforward: if you are near a forecourt that you know tends to be price-active, it is worth checking the current posted price before you pull in rather than assuming it matches what you saw on your last visit. Official UK government fuel price data is updated regularly and covers stations across the country, so you can look up a specific postcode to see what a station is currently charging and how recently that figure changed. Keeping an eye on prices in your local area, even briefly before a longer journey, is one of the simplest ways to avoid paying over the odds at the pump.
