Supermarket forecourts are undercutting the national average
By Anthony Sharkey, Chief Operating Officer, New Reg Limited
Drivers filling up at supermarket forecourts are paying around 1.9p a litre less for unleaded than the UK national average, according to official UK fuel price data.
Filling up at a supermarket forecourt saves drivers a small but real amount on every tank, with official UK fuel price data showing supermarket sites averaging 159.4p a litre for E10 unleaded against a national average of 161.3p across 7,817 forecourts.
That gap of 1.9p a litre works out at roughly 8p a gallon, or around £1.08 on a 57-litre family car tank. At a time when household budgets remain tight, that difference adds up over a year of regular fill-ups, particularly for drivers who cover a high mileage.
The figures, drawn from live prices at 1,487 supermarket sites, reflect a consistent pattern in which the larger supermarket chains use their buying power and high site volumes to keep pump prices below the broader market. Diesel is not part of the supermarket advantage story here: the national average for diesel stands at 181.2p a litre, and no comparable supermarket saving on diesel is indicated in the official data.
