Should I buy a diesel car in 2021?

Fuel prices in the UK have reached record highs in 2022, with the average price of petrol currently 168.67 pence per litre (ppl) for petrol and 181.15p for diesel.

In the Spring Budget on 23 March 2022 the Chancellor Rishi Sunak reduced fuel duty by 5p a litre until March 2023 in an attempt to counter previous record prices of 167.3p for petrol and 179.9p for diesel. 

This, along with the price of oil dropping, contributed to a decline in average pump prices in April 2022, although drivers did not feel the full benefit of the savings. 

The average price of petrol was 162.75p by the end of April 2022, falling by 0.5p a litre from the start of the month, according to the RAC. Diesel stayed the same at 177p in April 2022 (it was 177.44p on 1 April 2022 and 177.31p on 30 April 2022). 

April's average prices followed three months of fuel prices consistently reaching new record levels. March 2022 saw the largest ever increases in fuel prices. The average price of a litre of unleaded petrol went up by 11.62p and ended the month at 163.28p, while diesel rose 22.06p, ending the month at 177.29p, according to the RAC. 

It said the previous biggest monthly increase for petrol was in October 2021 when the prices rose by 7.43ppl. Diesel's previous worst month was May 2008, when the cost of a litre went up by 8.43ppl.

In 2021, the record was 147.72p for petrol and 150.96ppl for diesel on 22 November. Wholesale and retail prices dropped in December but began climbing again in January 2022.

Why are fuel prices going up?

The simple explanation why fuel prices in the UK have been going up is that the cost of a barrel of oil has risen. In 2020 the wholesale price of a barrel of crude oil was around $40, it more than doubled in 2021 with the ongoing impact of the Covid-19 pandemic affecting supply and demand.  

At the start of January 2022 the cost of oil was $79 but this had risen to $92 by the end of the month and went above $100 per barrel after Russia (the second largest oil producer in the world) invaded neighbouring Ukraine on 24 February 2022, making traders worried about disruption to the global supply chain. 

On 1 March 2022 the price of oil had jumped by $10 to $112.99 a barrel in response to the Russia-Ukraine crisis. The RAC predicted this was likely to take the average price of petrol towards 155p a litre and diesel to 160p.

The price of oil went on to hit $137.72 a barrel on 8 March - the highest it has been since 2008, although it fell to $109.98 by the end of the month. 

In April 2022 the price of oil dropped under $100 on three occasions but finished the month on $108.62 a barrel.

In May 2022, fuel prices have continued to fluctuate and are currently around  $113 a barrel. 

When the price of oil rises, fuel retailers often pass on the cost to consumers at the pumps although they can absorb some of the increases, as they did in January 2022 (wholesale prices rose by 4.9p for petrol and 3.6p for diesel but did not rise by as much as that at the pumps).

Fuel retailers have an important role to play in fuel prices. Competition between the 'big four' supermarkets Asda, Tesco, Morrisons and Sainsbury's has helped to reduce prices in the past - when one supermarket giant cuts their fuel prices others often follow. But in 2021 fuel retailers were heavily criticised for not cutting the cost of fuel at the pumps when the price of oil dropped towards the end of the year.

During February 2022, the average margin was 8p for each litre of petrol and just under 6p for each litre of diesel, compared to 16p and 12p respectively during December.

In April 2022 retailers' margins were far higher than in March 2022, according to the RAC Fuel Watch. It estimates retailers took around 4p more a litre in April than they did in March. 

The UK Government also has a major influence on fuel prices as both fuel duty (currently 52.95pp) and VAT (standard 20% rate) make up the majority of the price of petrol and diesel. 

Fuel duty was frozen from March 2011 to March 2022, bringing some relief for drivers in the midst of rising prices, while the Chancellor lowered it by 5ppl in the Spring Budget 2022. 

When the Government introduced E10 petrol in September 2021 it had an impact on fuel prices as ethanol is more expensive than petrol.

Other factors which influence wholesale prices, according to the RAC, are: oil refinery production and capacity, the pound to dollar exchange rate, as refined fuel is sold in US dollars per metric tonne; and distribution costs.

Where can I find the cheapest fuel prices near me?

Supermarkets, in general, have the cheapest fuel prices. The big four supermarkets - Asda, Morrisons, Sainsbury's and Tesco - all lowered prices after the 5p fuel duty cut.  BP-owned and Shell-owned fuel stations also applied the 5p cut (6p including VAT).

Asda had the lowest price petrol in April 2022 at 159.38p on average, and the cheapest diesel at 173.12p, on average. 

In contrast, the average price of a litre of petrol at motorway fuel stations rose by 0.67p in April 2022 to 182.08p while diesel increased by 0.83p to 192.34p.

When will fuel prices go down?

Fuel prices have been rising in the wake of Russia's invasion of Ukraine on 24 February 2022. With the oil price above $100 a barrel and retailers keen to pass on the increase in wholesale fuel quickly, new records were being set on an almost daily basis in the following weeks, as experts predicted.

Average petrol prices rose to 167.30p, while diesel climbed to 179.72 on 22 March 2022 before the Chancellor cut fuel duty by 5ppl.

Although average prices fell in April, motorists did not feel the full benefit. RAC fuel spokesman Simon Williams suggested that the biggest retailers were "protecting themselves from future rises".

"They will no doubt feel they were justified in not lowering their forecourt prices as wholesale costs are now rising again, in part due to the pound losing ground on the dollar, making it more expensive for retailers when they buy new stock," he said. 

The exchange rate worsening, combined with market uncertainty and the news that the EU is planning to phase out Russian oil are all likely to cause the price of a barrel of oil to rise, he warned.

Already in May 2022, March's record fuel prices have been broken. The latest fuel prices are 168.67p for petrol and 181.15p for diesel.
