RAC Fuel Watch data for April shows the latest rise is the result of a 25% increase in the cost of a barrel of oil from $36.51 to $45.49 over the course of the month.

As a result, the average price of petrol has risen to 108.27p (from 105.64p) while diesel is up 108p (from 105.41p) respectively.

Supermarket average prices rose by 3p a litre for both fuels with petrol rising from 102.68p per litre to 105.85p and diesel from 102.58p to 105.76p.

RAC fuel spokesman Simon Williams said: “The physical or spot price of Brent crude oil saw its largest one-month gain in price in the past 12 months. While this has had an adverse impact on the price motorists are paying for petrol and diesel on the forecourt, the world is still producing too much oil, which means prices should not rise much further, and may stabilise or even start to fall again.

“It’s worth remembering that while prices have gone up in both March and April motorists are still paying 7p per litre less for petrol and 11p per litre less for diesel than they were at this time a year ago which means a tank of unleaded is more than £3 cheaper and diesel is £6 less expensive.”
