Asda has become the first supermarket to publish local fuel prices online, following MP questioning over “sky-high” prices which have surged in recent months.

The move will allow motorists to check the price of petrol or diesel before they travel to one of the supermarkets filling stations, alongside other key information on the Asda store locator pages.

The latest fuel prices will be available at 10:30am each morning and will show the previous days closing price.

The Big 4 grocer has said it will continue to develop a system that will show real-time pricing and expects this to be in place in coming months.

Asda added that it will continue to work collaboratively with the government to develop an industry-wide fuel finder scheme.

The Competition and Markets Authority (CMA) found that drivers obtaining fuel from the UK’s four main supermarket-owned forecourts had paid an additional £900m for fuel last year, as a result of the retailers having hiked their profit margins.

As a result, the watchdog set out a voluntary scheme in July that asks supermarkets to release their fuel pricing information to give customers better comparison data on local rates.

An Asda spokesperson said: “Asda is proud to be the price leader in the fuel and by sharing our prices online customers will be able to find the best value at the pumps before they get in the car.”

This comes following a meeting with the Business and Trade Committee last month, which was described as “drawing teeth” as MPs accused Asda co-owner Mohsin Issa of failing to answer questions.

During the session, he insisted that the supermarket’s pricing strategy “has not changed” since the billionaire brothers bought the business in 2021.
