Fuel prices often feel like live data, but in reality every price you see has a limited lifespan.
Understanding how long prices usually remain accurate can help avoid frustration when you arrive at the pump.
Prices do not update constantly
Most UK petrol stations do not update prices minute by minute.
Some update once per day, others only when nearby competitors move. A small number update more frequently, but this is not typical.
Retailer size plays a role
Larger chains usually update prices more often because their systems are automated.
Independent stations may update less frequently, which can sometimes result in prices lagging behind wider market changes.
Time of day can matter
Prices seen early in the morning are often different from those later in the day.
Stations on commuter routes may adjust prices around peak travel times, while quieter locations remain unchanged.
How to use price data sensibly
- Check prices shortly before travelling
- Compare several nearby stations
- Be cautious with prices that are several days old
