UK petrol and diesel prices: records broken again as prices skyrocket

Petrol and diesel pump prices have both reached record average highs for the second time in one week

The average pump prices of petrol and diesel in the UK have both hit record highs for the second time in the space of a week.

Unleaded petrol now costs an average of 168.24p per litre, while diesel stands at 181p per litre, according to the latest RAC Fuel Watch data.

Earlier in the week, petrol and diesel had reached then-highs of 167.64p and 180.29p per litre respectively. Before that, previous records had both been set in late March, when petrol cost an average of 167.30p and diesel was 179.90p per litre.

It now costs £92.53 to fill an average 55-litre family car with petrol, or £99.55 to do so with diesel. The average is even higher at motorway service stations, where petrol is an average of 186.68p and diesel is 197.3p per litre.

RAC fuel spokesperson Simon Williams said: “So far in May, a litre of unleaded has rocketed by more than 5p a litre and diesel by 3.5p. Since the start of the year, it’s a far bleaker picture as petrol is 22.5p higher and diesel an astronomical 32p.

“While wholesale prices dropped on Wednesday, indicating we may have passed the peak, drivers should brace themselves for further pump price rises as retailers who have had to buy new stock this week pass on their increased costs in the coming days. Drivers badly need further help from the Government, particularly as the Treasury is benefiting considerably from the windfall that 20 per cent VAT brings them on these record high prices.”

Why are diesel and petrol so expensive?

Russia is one of the world’s largest producers of oil and gas, so any disruptions to its production processes has a global impact.

With Russia having launched a full-scale invasion of Ukraine and facing international sanctions, there’s potential for significant disruption to supplies. Russia produces 4.5 million barrels of oil each day, and only Saudi Arabia produces more.

The sanctions levied against Russia so far have targeted banks and oligarchs rather than the country’s energy sector, but factors such as Germany’s postponement of the Nord Stream 2 gas pipeline will have an effect on the energy market overall. Russia also has the ability to reduce oil exports to Europe in a tit-for-tat response to economic sanctions, and experts suggest Saudi Arabian oil fields could struggle to increase production sufficiently to counter such measures.

“Opec, the oil producers’ cartel, is already struggling to meet its output targets as demand for crude rebounds following the easing of lockdown restrictions. This has pushed up prices, with analysts warning there is limited capacity to increase supplies if flows from Russia are affected by sanctions,” the Financial Times newspaper has reported.

What makes up the price of UK fuel?

The price of fuel can be divided into three sections; the taxes imposed by the Government, the costs of drilling, refining and transporting, and the profit margins for the fuel companies.

For petrol, diesel and bioethanols, the Government gets around 65 per cent of the overall cost through fuel duty and value added tax (VAT). The fuel duty represents the fixed price of fuel – it stays the same regardless how much overall oil prices fluctuate. Currently, the Treasury adds 57.95 pence to each litre of fuel through fuel duty, and another 20 per cent through VAT. How much you pay in VAT depends on how much fuel you purchase.

The second biggest chunk comes from the wholesale costs of the fuel itself. The wholesale cost is a combination of currency exchange rates, global oil prices, and even domestic supply and demand.

When will fuel prices go down?

Experts predict high fuel costs will be with us for the foreseeable future, and it’s not just down to the crisis in Ukraine - energy costs have been high for the best part of a year already as demand surged as the world emerged from lockdown.

Part of the problem is down to the fact that relatively low barrel prices in recent years have put plans to drill for new reserves on hold. That’s true in Africa, the US and South America, and while the current high prices may increase interest in exploring new reserves, it can take years for new wells to come on stream in volumes required to affect the market.

Why is supermarket fuel cheaper than an independent forecourt?

Supermarket forecourts usually offer the cheapest fuel prices and this is because of the market power supermarkets hold. Companies like Asda, Tesco, Sainsbury’s and Morrisons are all in competition with one another, so they keep fuel prices as low as possible hoping that when motorists come to fill their tank, they might do their weekly grocery shopping, too. 

There are persistent rumours that supermarket fuel contains fewer additives and is of lesser quality than fuel from traditional forecourts, but there’s little hard evidence of this. All fuel sold in the UK has to abide by the standards set in the Motor Fuel Regulation.

Why is fuel so expensive on motorways?

Motorway fuel stations argue the reason their prices are higher is that many of them are open 24 hours a day and offer more services than a regular forecourt. Motorway fuel stations also pay high rent prices for the buildings they operate.

In more remote areas, fuel is often more expensive because of the higher transport and supply costs, but according to RAC fuel spokesman Simon Williams, this doesn’t apply to motorway stations: “We can see no reason why motorway fuel should be so much more expensive. In fact, arguably it is much easier from a delivery point of view than it is getting fuel to urban filling stations.”

Why is diesel more expensive than petrol?

Although diesel and petrol are taxed the same by the Treasury, historically diesel has been more expensive than petrol, as domestic refineries have struggled to meet demand. This has forced the UK to import diesel from other countries at a greater rate than petrol. In addition, diesel prices are pushed up by the cost of the additives that go into the fuel.

Furthermore, the gap between UK petrol and diesel prices widens during the winter. The end of the US “driving season” means retailers have a surplus of petrol they can’t export, so they sell it here at a lower price. Diesel demand, meanwhile, increases across continental Europe, where the fuel is commonly used in heating oil.

Recently, the influx of cheap diesel from countries like Saudi Arabia has turned the tide, swinging diesel wholesale prices closer to that of petrol, and bringing the pump price down with it. However the fact that we get a higher percentage of diesel from Russia than petrol means the advantage has swung the other way again.
