Supermarkets Hiked Fuel Prices, Costing UK Motorists Nearly £1 Billion, Regulator Finds

Average supermarket fuel margins rose by 6p per litre between 2019 and 2022, resulting in an estimated additional cost of £900 million for customers of Asda, Tesco, Sainsbury's, and Morrisons.
Margins on diesel across all fuel retailers increased, costing drivers an extra 13p per litre in the first five months of this year.
The UK government plans to introduce a new law requiring fuel retailers to provide up-to-date pricing information to third parties, potentially leading to the creation of price comparison apps and websites.
The government will grant new powers to a public organization to monitor pump prices and alert ministers if intervention is necessary.
Asda was fined £60,000 for failing to provide relevant information in a timely manner, and the CMA emphasized the need to reignite competition among fuel retailers.
