Supermarket fuel now 3.2p cheaper per litre than UK average

Drivers who fill up at supermarket forecourts are currently paying noticeably less for unleaded petrol than those using other filling stations, with official UK fuel price data showing a gap of 3.2p per litre between the two.

Across all 7,806 forecourts tracked in the official figures, the average price for E10 unleaded sits at 151.4p a litre, which works out at roughly £6.88 a gallon. Supermarket sites, covering 1,492 locations nationwide, are averaging 148.2p a litre, or about £6.74 a gallon. On a typical 50-litre fill, that difference amounts to £1.60 saved each time you visit a supermarket pump rather than an independent or branded forecourt.

Diesel remains considerably more expensive than petrol regardless of where you buy it, with the national average sitting at 165.0p a litre according to the same official data. The figures reflect live prices and can shift day to day, so the precise saving will vary, but the pattern of supermarkets offering lower prices than the wider market has been consistent for some time.

For most drivers, the practical takeaway is straightforward: if a supermarket forecourt is on your route, it is worth stopping there rather than pulling into the nearest available station. Over a year of regular driving, the saving adds up to a meaningful amount.
