A new RAC Fuel Watch analysis has has found that UK motorists are still paying more on average than they should be for petrol and diesel - despite being overcharged last year. Petrol and diesel in the UK in July have remained 'stubbornly static' despite calls to lover the threshold, according to a new study conducted by RAC Fuel Watch. The figures from a new analysis published on Tuesday (July 6) show the average fuel prices remained at 145p (144.

76p) for petrol and 150p (149.8p) per litre for diesel last month. It comes after fuel retailers were exposed by the Competition and Markets Authority (CMA) to have been over charging drivers by £1.

6bn this same time last year. Despite the wholesale prices bringing down the cost at pumps, drivers are still on average paying 5p more than they should be for petrol and 8p more for diesel. This equates to almost £3 a tank (£2.

75) for petrol and £4.40 for diesel amid the cost of living crisis. Fuel Watch, the RAC's petrol and diesel price monitoring initiative, helps ensure retailers charge a fair price at all the UK’s forecourts.

Their analysis of wholesale prices shows average retailer margins are coming in at 13p a litre for unleaded, up 3p in July, and at 14.5p for diesel. Both of these prices are well above the long-term averages of 8p and means drivers should actually be paying 140p for unleaded and 142p for diesel.

Meanwhile, drivers in Northern Ireland are paying 5p lower in petrol and 8p less in diesel per litre compared to.
