UK Petrol & Diesel Prices This Week – 15 June 2026
UK petrol prices remain a major household cost for drivers nationwide. This week, the national average price of petrol (E10) stands at 156.1p per litre, while diesel (B7) averages 187.9p per litre across the country.
With fuel forming one of the largest ongoing expenses for motorists, even small regional differences can significantly impact weekly and monthly budgets.
National Petrol & Diesel Overview
Petrol (E10) is currently averaging 156.1p per litre nationwide based on the latest official UK Government Fuel Finder data. Diesel (B7) is averaging 187.9p per litre.
For a typical 55-litre family car, filling up with petrol at the current national average costs approximately £85.9. A full diesel tank costs around £103.3.
These totals highlight how even modest price movements can quickly affect household budgets.
Regional Differences Across the UK
Fuel prices vary considerably by location.
This week, Belfast is the cheapest major city for petrol at 149.9p per litre.
At the other end of the scale, Southampton is currently the most expensive major city, averaging 159p per litre.
The gap between the cheapest and most expensive cities now stands at 9.1p per litre.
For drivers filling a 55-litre tank, that regional difference equates to roughly £5 per fill-up — a meaningful saving simply by choosing the right forecourt.
Why Prices Vary by Region
Regional fuel prices are influenced by a combination of factors including:
- Local competition between forecourts
- Supermarket versus branded station pricing strategies
- Transport and distribution costs
- Urban versus rural operating expenses
Areas with strong supermarket competition often see tighter pricing, while regions with fewer stations can experience higher averages.
What This Means for Drivers
Fuel costs remain highly sensitive to location. While national averages provide a useful benchmark, individual motorists can often save several pounds per tank by comparing nearby stations.
Over the course of a year, even a £5 saving per tank can add up to over £250 for drivers filling up weekly.
Monitoring prices locally remains one of the simplest ways to reduce overall motoring costs.
