Asda has purchased 15 petrol stations from Top 50 Indie Rontec in the latest move towards its aim of opening 100 standalone petrol stations by the end of 2018.

Asda intends to close and convert the 15 petrol stations over a number of weeks and will re-open the sites under the Asda brand by summer 2015. The first five sites are expected to re-open from mid-March (Staines, Tottenham White Hart Lane, Tilehurst, Plymouth and Woodville).

In addition to the fuel offer, customers will have access to a selection of everyday essentials in the site’s stores as well as the full Asda range through its online click and collect service. Shoppers can complete a full weekly shop by ordering online and collecting it at the site.

Asda’s president and CEO Andy Clarke said: "We have set out a clear ambition to lead online and expand further into London and the South East, opening 100 petrol stations and 1,000 Click and Collect sites by 2018."

Four of the locations are in London/inside the M25, four in the South/South East, four in the Midlands, two in the north of England, and one in South Wales. The Click and Collect service will not be available at two sites due to restrictions.
