Drivers are set to enjoy the cheapest Christmas fuel prices since the pandemic, figures suggest.

This is despite a slight rise in November when petrol went up by a penny to 136.5p but it is still 10.5p cheaper than a year ago, according to the latest data from RAC Fuel Watch.

Diesel went up by 1.8p to 142.25p but remained 12p cheaper than the same time last year.

The prices take the cost of full tanks for 55-litre family cars to £75 for petrol and £78 for diesel. This is £5.75 and £6.60 less than a year ago respectively.

Compared to two years ago, nine months after the price of oil rocketed due to Russia invading Ukraine, petrol is now 23.4p or £12.90 a tank less, while diesel is 41.7p or £22.90 a tank cheaper.

Fuel prices set to be cheapest at Christmas since coronavirus pandemic

At the end of November, a litre of petrol bought at one of the big four supermarkets cost 133.2p, 3.3p cheaper than the UK average, while diesel was 138.6p, 3.6p less than the average price paid on UK forecourts, the RAC reported.

Prices at the end of the month were cheapest in Northern Ireland with petrol averaging 130.6p and diesel 135.2p which is 6p and 7p less than the UK average.

England was most expensive for fuel in UK in November

England was the most expensive with petrol at an average of 136p and diesel at 141.7p, while Scotland and Wales were 134.5p and 134.9p for petrol and 140.6p and 140.2p for diesel respectively.

The cost of oil had remained broadly stable, averaging 73 US dollars a barrel, leading to little change in wholesale prices.

However, the RAC’s figures follow the competition watchdog warning last week that drivers were still paying more for fuel than they should due to “stubbornly high” margins.

The Competition and Markets Authority (CMA) said fuel margins remained higher than historic levels and it remained concerned about weakened competition in the sector.

Supermarket fuel margins increased from 7% in April to 8.1% in August while non-supermarket fuel margins rose from 7.8% in April to 10.2% in August, the watchdog said.

RAC head of policy Simon Williams said: “Heading up to the most expensive time of year for families, it’s good to see that this Christmas is set to be the cheapest for fuel since the pandemic.

“Despite both petrol and diesel rising by a penny and two pence respectively in November, the difference to a year ago is considerable with petrol 10.5p lower and diesel 12p less.

“This is great news for people making long festive journeys to visit friends and families as it should save them around £6 on a tank of fuel compared to last year.

“While conditions are clearly better for drivers this Christmas than previous ones, we’re still conscious that prices at the pumps could be slightly cheaper if retailer margins were lower.

“So, it was disappointing to see last week that the Competition and Markets Authority has once again expressed concern about a lack of competition among fuel retailers. This comes on the back of the CMA concluding drivers were overcharged by £1.6bn in 2023.

“We hope the Government’s commitment at the Budget to introducing a mandatory fuel price finding scheme next year will spark competition and lead to a fairer fuel retailing landscape that delivers better value for drivers wherever they fill up.”
