Finding Cheap Diesel in the UK
Diesel prices vary significantly across the UK. The cheapest forecourts are consistently supermarkets — Asda, Tesco, Sainsbury's and Morrisons — which typically undercut branded stations by 5 to 10 pence per litre. Costco members get even better deals, though there are only around 20 Costco forecourts nationwide.
Standard vs Premium Diesel
At the pump, you'll see two diesel options. B7S (standard diesel) is what most drivers should use — it meets all required specifications and costs significantly less. B7P (premium diesel) includes extra additives for engine cleaning and slightly better combustion, but costs 18 to 20 pence more per litre.

Tips for Diesel Drivers
- Compare prices before every fill-up — even a 5p difference on a 60-litre tank saves £3
- Stick to standard B7S diesel unless you have a specific reason to use premium
- Avoid motorway services where diesel can be 20p+ more per litre
- Consider using an injector cleaner every 5,000 miles instead of paying for B7P daily
- Use our petrol vs diesel calculator if you're deciding between fuel types for your next car

Frequently Asked Questions
How do I find the cheapest diesel near me?
Enter your postcode or town in our comparison tool and select diesel (B7S) as your fuel type. We'll show you every forecourt nearby sorted by price, covering over 7,000 UK stations.
What is the difference between B7S and B7P diesel?
B7S is standard diesel containing up to 7% biodiesel — the regular pump diesel at every forecourt. B7P is premium diesel (Shell V-Power, BP Ultimate) with extra cleaning additives and a higher cetane number. B7P typically costs 18 to 20 pence more per litre.
Is premium diesel worth the extra cost?
For most drivers, no. The cleaning benefits can be achieved more cheaply with aftermarket injector cleaner (£5-15 per bottle). Premium diesel may help older high-mileage engines or vehicles that tow regularly, but the efficiency gains are too small to offset the price premium for everyday use.
Why is diesel more expensive than petrol in the UK?
Despite the same fuel duty rate, diesel is more expensive due to higher refining costs and stronger European demand for diesel. The wholesale price of diesel is typically higher than petrol, which translates to higher pump prices.
Where is diesel cheapest in the UK?
Supermarket forecourts (Asda, Tesco, Sainsbury's, Morrisons) consistently offer the cheapest diesel. Costco is typically cheapest of all. Areas with strong competition and proximity to refineries (North West, Humberside) tend to have lower prices.
