Both petrol and diesel reduced by over a penny a litre in January making it three consecutive months of falling fuel prices.
Data from RAC Fuel Watch* shows the UK average price of unleaded came down by 1.32p to 120.92p while diesel dropped 1.27p to 130.01p.
This means it now costs an average of £65.78 to fill up a 55-litre family car with petrol – £6 less than it did at the end of October. A tank of diesel, however, has only come down £3.78 to £71.50 over the same period.
Prices at the country’s four biggest supermarkets are an average of 3p a litre lower at 116.66p for petrol and 125.43p for diesel. At motorway service areas, however, a litre of unleaded sets drivers back 138.87p and diesel 147.55p.
RAC Fuel Watch figures show the wholesale price of petrol stayed flat in January while diesel increased by 2p a litre, but when compared to retail prices they were low still low enough to demand pump price reductions during the month. Sadly for drivers though, retailers decided not to pass these on.
The RAC says this explains why the UK average price of fuel has fallen despite the wholesale market being static for unleaded and rising for diesel. If retailers were to pass on existing savings in their wholesale costs the price of petrol ought to reduce by 3p a litre in the next two weeks, and diesel by 2p a litre.
RAC fuel spokesperson Simon Williams said: “While it’s obviously good news the price of fuel has fallen for three months in a row, the story behind the simple forecourt average figures is quite disturbing. Looking at the wholesale data over the last two months reveals that we should have been paying far less for our petrol and diesel than we have been.
“Unfortunately, three of supermarket fuel retailers appear to have changed their pricing policies for the long term by increasing the margin they take on a litre of petrol to about 2p. This has meant the average price of unleaded has not reduced by as much as it should have because smaller retailers nearby haven’t had to lower their prices as much in order to compete.
“The wholesale fuel market operates very transparently, but the same can’t be said of the retail market. We understand retailers are free to charge what they like for their fuel and that it’s then up to consumers whether they’re prepared to pay their prices or not. Unfortunately, consumers don’t have an easy way of knowing whether they are being charged a fair price so they have to trust they aren’t being ripped off. That’s why we always encourage drivers to check the current average price of petrol and diesel, and see if they can beat that price when paying for fuel locally.
“Combine this with the fact some bigger retailers vary their prices from location to location, fuel is an essential purchase for most people and that shopping around is not that easy, and you have the perfect recipe for drivers being charged over the odds for what is essentially a commodity.”
