RAC head of policy Simon Williams said: “It's very concerning that margins on fuel remain historically high, competition is still lacking and that some retailers were deemed not to have reduced prices as quickly as they should have when the diesel wholesale price fell earlier in the summer.
“We're therefore pleased the CMA is going to be taking a closer look at retailer pricing strategies and whether wholesale price changes are reflected at the pumps fast enough.
“We also urge the watchdog to compare fuel retailing in Northern Ireland with the rest of the UK, as petrol and diesel are currently being sold there for an average of 8p less a litre – meaning the cost of filling a family car in Northern Ireland is around £4.40 less than elsewhere.
“If fuel can be sold there at lower prices, then it seems drivers elsewhere aren't being treated fairly.
“It's positive that drivers can now find prices for 99 per cent of fuel sold in the UK on Fuel Finder.
“We urge every driver to use fuel comparison tools such as the myRAC app to make sure they buy the cheapest fuel near them.”
