The average price of a litre of petrol and diesel rose in September to make a tank £12 more expensive than a year ago, according to new RAC Fuel Watch data.

Unleaded increased by 1.5p to 136.83p while diesel rose by 2.5p to 139.25p, making the price of petrol 22p a litre more expensive than a year ago (114.61p 30 September 2020) and diesel 21p dearer (118.10p).

RAC said both fuels are at prices last seen eight years ago in autumn 2013, with petrol only being 5.65p off the all-time high of 142.48p and diesel 8.68p off the record of 147.93p.

The rise at the pumps has not been driven by the fuel delivery crisis but by a 10.65% increase in the price of oil from $71.29 to $78.88 throughout September, said the RAC. 

Simon Williams, fuel spokesman at the RAC, said: “Not only are motorists struggling to put fuel in their vehicles, but they are also having to pay through the nose for it as the rising cost of a barrel of oil is causing further pain at the pumps.

“As life moves ever closer to normal as the world gets to grips with Covid-19, demand for oil is outpacing supply, and with producer group OPEC+ deciding on Monday not to release more oil, the barrel price has now broken through the $80-mark for the first time in more than three years.

“This looks likely to spell further misery for drivers at the pumps as we head towards Christmas, especially as some analysts are predicting the price could even hit $90 before the end of the year.

“If this were to happen, we could see the average price of unleaded hit a new record of around 143p per litre. Diesel would shoot up to 145p which is only 3p off the record high of 147.93 in April 2021.”

According to the RAC, for those who have filled up a 55-litre family car with petrol at the end of September, they would have paid £75.26 – up 85p in September and £12.22 on 12 months ago.

A full tank of diesel is now £76.59 – up £1.40 in September and £11.63 more than a year ago, the data found. 

The RAC said prices at four major supermarkets were 4p a litre cheaper than the UK average while at motorway services they were 15p more expensive for petrol at 151.55p and 156.35p for diesel.

Asda sold the cheapest unleaded at 132p while Sainsbury’s offered the lowest price diesel at 134.28p.

Williams added: “Drivers have had to endure the average price of petrol going up for 10 out of the last 12 months and now, because of the supply crisis, many have had great difficulty getting hold of it just so they can go about their daily lives.

“While we’ve heard of some smaller retailers taking advantage of the situation by charging very high prices for their fuel, these cases appear to be few and far between, with most retailers acting responsibly.

“As forecourts’ fuel stocks return to normal drivers will inevitably switch from worrying about whether they can get the petrol or diesel they need to just how much a fill-up is costing them.

“Drivers in London and South East will undoubtedly feel particularly hard done by as they are still experiencing problems with getting hold of fuel while also paying the highest prices in the UK.”
