UK fuel prices this week: petrol 152.8p, diesel 172.1p

Figures from official UK government fuel-price data, covering 2,586 forecourts across the UK, put the average price of unleaded E10 at 152.8p per litre this week, with diesel B7 sitting notably higher at 172.1p. For a typical 55-litre family car tank, that means a full fill of petrol costs around £84, while diesel drivers are paying closer to £95.

The 19.3p gap between petrol and diesel continues to weigh on van drivers, tradespeople and anyone running an older oil-burning car. That spread alone adds roughly £10.60 to every diesel fill compared with petrol, so the fuel type you drive matters as much as where you buy.

For unleaded, the cheapest major-brand option identified in the data is AppleGreen at 138.3p per litre. Choosing that over the national average saves around 14.5p per litre, or roughly £8 on a 55-litre fill. It is a meaningful difference for drivers who commute regularly or cover high mileage.

With running costs still a key factor in any buying decision, tools that let drivers compare total ownership expenses before committing to a vehicle are increasingly useful.
