What today’s supermarket fuel prices mean for drivers
Fuel prices can vary slightly between supermarkets, and the cheapest option can change from day to day depending on local pricing, supply costs and competition.
In many cases, the difference between supermarkets may only be a few pence per litre. However, over the course of a full tank, those small differences can still add up — especially for drivers who fill up regularly.

Why Supermarket Fuel Prices Vary Across the UK
Supermarket fuel prices are not always the same across every petrol station in the UK.
Several factors can influence the price of petrol and diesel at individual supermarket forecourts, including:
- Local competition - stations in more competitive areas may price more aggressively.
- Regional operating costs - staffing, utilities and site overheads can vary by location.
- Traffic levels and demand - busier forecourts may respond differently to customer demand.
- Distribution and supply logistics - transport routes and delivery costs can differ across the country.
- Retailer pricing strategy - each supermarket may take a slightly different approach to fuel pricing.
Because of these differences, it is normal to see a gap between the lowest and highest supermarket fuel prices on the same day.
How We Calculate Supermarket Fuel Prices
This page uses supermarket forecourt fuel price data sourced from official UK government datasets (via data published on GOV.UK).
For each fuel type, we calculate:
- the average reported retailer price
- the cheapest recorded site price
- the highest recorded site price
- the number of supermarket forecourts included in the comparison
Prices can change throughout the day, and some retailers or locations may have more complete data coverage than others. The figures shown reflect the latest available data at the time of update.
