Since the war started in Ukraine petrol and diesel has more than doubled at supermarket forecourts.
The RAC has said there has been an increase of around 10p per litre which has led to higher fuel costs at the pumps.
According to analysis by the RAC, Sainsbury’s, Morrisons, Tesco and Asda were making in February 2022 when Russia invaded Ukraine, an average of 4.7p per litre and in 2016 supermarket margins were 2.3p per litre.
RAC fuel spokesman Simon Williams said, “While we accept the cost of running forecourts might have increased, these bloated margins must make difficult reading for the millions of drivers who are already battling the rising cost of living.
“In short, this means everyone is paying more than they should be to a lesser or greater extent depending on where they live.
“We hope artificially high pump prices will become a thing of the past due to the actions promised by the Government resulting from the Competition and Markets Authority (CMA) report earlier this month that showed supermarkets had overcharged drivers to the tune of £900 million last year.
“Their recommendation that a price monitoring body is set up and that retailers are mandated to provide live prices for fuel finder apps is very welcome and long overdue.”
A spokesperson for Asda said, “Asda is proud to be a fuel price leader – and an Asda petrol station in a local area keeps prices down for all motorists.
“In support of calls for greater transparency in fuel pricing, we will be making our prices visible for all of our fuel stations in the coming weeks so motorists can be confident they are getting the best prices when filling up at Asda.”
