Diesel came down by almost 7p to 154.40p but is also being overcharged by 5p a litre due to savings from lower wholesale costs not being passed on by retailers to drivers at the pumps.
The RAC’s analysis shows that average retailer margin on petrol is now 17p a litre and 13p for diesel. The long-term averages are 7p for petrol and 8p for diesel.
This news comes as drivers are still supposed to be benefitting from a 5p-a-litre duty cut implemented in March 2022. Instead, the figures show it’s major retailers which are gaining from this.
The RAC estimates drivers have lost out to the tune of a staggering £184m over the last two months as a result of retailers not passing on the 5p duty cut.
What should fuel cost in the UK?
The RAC believes petrol should be sold for an average of 137p and diesel for 150p, based on retailers taking a fairer margin. This means drivers are currently paying around £5 more than they should be to fill up an average 55-litre family car (£80.62 v £75.35). For diesel, the figure is around £2.50 (£84.92 v £82.50).
In stark contrast, membership-only retailer Costco is currently selling unleaded for an average of 133.7p and diesel for 144p – 14p and 11p less than the UK average respectively. In Northern Ireland unleaded is being sold for an average of 141.4p and diesel for 149.5p – 5.5p and 5p less than the UK average.
The fuel finder feature in the free myRAC app shows independently run forecourt Grindley Brook in Whitchurch, Shropshire, is only charging 131.9p for petrol – matching Costco’s cheapest price, and 15p cheaper than the UK average – and 143.9p for diesel, 10.5p lower than the UK average. By comparison the average price of unleaded at the big four supermarkets is 143.37p and 151.48p for diesel.
RAC Fuel Watch data shows that the wholesale price of petrol dropped by 9p a litre in November and diesel by 7p on the back of oil averaging $84 across the month and the pound gaining ground on the dollar closing November at $1.26, up from $1.21 at the start. A litre of unleaded currently costs retailers just 106p and diesel 117p.
What does it mean for drivers?
RAC fuel spokesman Simon Williams said: “While the price of fuel fell in November, the truth is there is no reason whatsoever for drivers to be jubilant as the data clearly shows they are continuing to get a rough deal at the pumps, unless they live in Northern Ireland. Wholesale fuel costs have been falling for months, so they should be paying around 137p for petrol, instead of a whopping 147p. Diesel is also overpriced at 154.40p when it should be on sale for under 150p.
“This is extremely worrying as the biggest retailers don’t seem to have heeded the warnings levelled at them by Energy Secretary Claire Coutinho at the end of October saying she wouldn’t hesitate to call out those that rip off the public.
“While the Energy Secretary’s action may have encouraged retailers to begin reducing their prices, it’s undoubtedly a case of far too little, far too late. The wholesale market data the RAC analyses shows the true picture and unfortunately, for the Government and drivers, it shows the 5p-a-litre duty cut is not getting to drivers at all, and prices aren’t falling nearly fast enough yet again.
“We’ve contacted her department to explain what’s really going on with a view to prompting greater and more effective intervention. If a price monitoring body had already been set up by now – as recommended by the Competition and Markets Authority and accepted by the Government – then this might have been prevented and people might finally be getting a fairer deal at the pumps.
“We reiterate our call to the biggest retailers to significantly cut their prices to mirror what’s happening with greatly reduced wholesale costs.”
Drivers wanting to save as much as they can on the forecourt should download the free myRAC app from the App Store or Google Play and start using its fuel finder feature as it can save up to 6p a litre.3
Up to five searches a day over a two, five or 10-mile radius can be made, with each giving the five cheapest prices.
The RAC Fuel Watch web page has more information about the average price of petrol and diesel at the big four supermarkets and at motorway services. It also features graphs showing average prices since 2000 as well as a daily financial breakdown of the cost of a litre of petrol and diesel.
