Tesco, Asda, Morrisons, Sainsbury's drivers warned they have been 'seriously overcharged'

Fuel prices have spiralled with a 10p per litre hike as petrol and diesel drivers demand an end to "unfair" costs. Tesco, Asda, Morrisons, Sainsbury's motorists have faced increased costs at the pump, alongside BP, Texaco, Shell and Esso motorists.

Drivers are now paying £5.50 more every time they fill up compared to January. According to RAC Fuel Watch, the average price of a litre of petrol increased by 3p to 150p in April alone with average diesel prices rising by 2p per litre to 157.8p last month.

Simon Williams, fuel spokesman at RAC, said: “Drivers are once again having to dig deep just to go about their daily lives. Our data shows petrol and diesel have now gone up 10p a litre so far this year on the back of further increases in April of 3p and 2p respectively.

“Some of this is down to the oil price and the pound-to-dollar exchange rate making wholesale petrol more expensive for retailers to buy. But unfortunately, it’s also very apparent that retailers are making massive margins on diesel.

"Worryingly, the CMA’s warning shot about higher retailer margins at the end of March appears to have fallen on deaf ears, meaning drivers are once again being seriously overcharged for diesel.” Gordon Balmer, executive director of the Petrol Retailers Association warned that petrol retailers and supermarkets in the UK are operating on "razor thin margins" in a highly competitive market.

He said: “It is disappointing that we are constantly having to devote time and resource to correcting the inaccurate narrative offered by some commentators about pump price increases." Mr Balmer went on, saying: We are doing all we can through the appropriate policy channels to address this issue, while others would prefer to offer criticism without taking the time to understand how the industry works."
