UK petrol and diesel prices: four straight months of price rises


The average prices of both petrol and diesel increased in May due to continuously rising wholesale costs

Drivers in the UK received another blow to their wallets at the pumps last month, with May becoming the fourth consecutive month of petrol and diesel price rises.

The average price of petrol increased by 2.34p to 130.57p per litre, while diesel rose 1.74p to 135.54p per litre – increases of 11p and 7p respectively since the start of February – according to RAC Fuel Watch data.

This means the price of refuelling an average 55-litre family car is £71.81 for petrol – £1.29 more than April and £6 more than the start of February – and £74.55 for diesel – £3.80 more than February.

The rise in pump prices was driven by a continuing increase in the wholesale cost of fuel, with May seeing oil prices rise to more than $70 (£55) per barrel and the pound weakening four per cent against the dollar. By the end of the month, though, the price of a barrel of oil lowered again to around $65 (£51), which could mean a slight easing of pump prices.

In terms of regions, the north-east saw the biggest monthly price rise in May for petrol, increasing 2.71p to 130.25p per litre. As for diesel, prices rose the most in the East Midlands, jumping 1.95p to 135.81p per litre.

The south-east was the region where both fuels cost the most – 131.41p per litre for petrol and 136.46p per litre for diesel. Meanwhile, Northern Ireland was the cheapest for both, with petrol costing 128.99p per litre and diesel at 132.56p per litre.

RAC fuel spokesperson Simon Williams pointed out that, oil prices closed out the month with a nine per cent decrease to $65 per barrel, this should be reflected at the pumps.

Williams also described the cost of diesel as having been “overinflated” for more than a month, saying: “The wholesale price of diesel has now been lower than petrol since 17 May, yet there is currently an average difference of 5p between the two on our forecourts. Consequently, there is scope to cut the price of diesel by at least 6p a litre.”

MPs call for fuel price watchdog

MPs are calling on the Government to set up an independent fuel price watchdog by the name of ‘Pumpwatch’ following accusations that fuel retailers are increasing their profit margins at the expense of motorists.

The All-Party Parliamentary Group (APPG) for Fair Fuel says fuel retailers made an average profit of 8p per litre in the first nine months of 2018, but by the end of the year this figure had increased to more than 13p per litre. Meanwhile, the average profit margin on diesel prices rose from 8.6p to 11p per litre.

Under the APPG for Fair Fuel’s proposals – which follows a petition by pressure group FairFuel UK that collected more than 14,000 signatures – fuel stations which agreed to charge fair prices would be allowed to display a “kitemark” logo.

• Drivers should pay for fuel in advance, says police chief

Conservative MP Kirstene Hair, chair of the APPG for Fair Fuel, commented: “Drivers need reassurance that they are not paying way over the odds for fuel.

“In rural communities where public transport is poor and unreliable, people need their vehicles to get from A to B. It is essential that they pay the fairest price. That is where a price monitoring system would support them.”

Howard Cox, founder of FairFuel UK and secretary to the APPG for Fair Fuel, added: “We need ‘Pumpwatch’ now to ensure pricing fairness for both consumers and hardworking fuel retailers, too.

“Most of the profiteering is at wholesale level, not by small independent retailers, who are also victims of the greedy fuel supply chain.”

The news comes as the latest RAC Fuel Watch data shows the price of fuel at the pump did fall as much as it should have in December in line with oil prices.

The average price of unleaded fell 2.75p from 123.67p to 120.92p per litre last month, while diesel was reduced by 3.08p from 133.09p to 130.01p.

However, oil decreased in value by 14.5 per cent at the start of December, which should have meant a considerable drop in pump prices, with the RAC calling for fuel petrol and diesel prices to fall by 8p per litre and 10p per litre respectively in the next month.

RAC fuel spokesperson Simon Williams said “drivers should feel cheated” by the fact pump prices had not fallen as much as they should have and said “smaller retailers ought to be moving their prices down on their own without having to be forced to do so by nearby supermarkets”.

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.

Finally, the smallest share of what motorists have to pay for fuel comes from the filling stations themselves. A typical fuel station profits around 2p-5p per litre, but tough competition can drive this down further. Supermarkets increasingly use fuel prices as a loss leader to tempt customers in. 

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. 

However, the AA’s Fuel Price Report found that supermarket prices are getting closer and closer to prices on independent forecourts. The price gap between the Big-Four (Tesco, Asda, Sainsbury’s and Morrisons) and non-supermarket rivals has fallen below 3ppl for the first time in 12 months. 

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 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.

However, 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.

Why is fuel so expensive on motorways? 

Recent figures from the RAC suggest motorists topping up at a motorway fuel station pay up to 15 pence per litre more than elsewhere. 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.”

A new pilot scheme by the UK Government is installing electronic boards on the M5 between Bristol and Exeter that display motorway fuel prices. Similar systems can be found in countries like France, and if the trial is deemed successful, more motorways across the UK will see electronic signs posting fuel prices. This would provide some much-needed price transparency for motorway drivers.
