Asda has unveiled a £50m store upgrade programme designed to improve the shopping experience for customers in its larger supermarkets and superstores.

The plans, which will begin at the grocer’s Long Eaton store in Nottingham and will run across a total of 170 stores, are expected to be completed by the end of November.

As part of the programme, 50 larger stores will receive major upgrades, including the introduction of new in-store services and features, such as a new George department in some stores, new foyers, new seasonal aisles, new food-to-go services, new counters, and new flooring and lighting.

The remaining stores will receive refreshed exterior and interior decoration to reflect Asda’s new brand identity, which was unveiled earlier this month, and includes an updated logo, typography and colour palette.

These stores will also receive new trolley bays, new signage, improved toilet facilities and exterior landscaping work.

As well as the Long Eaton store, other sites undergoing changes over the coming months include Coventry, Altrincham, Dundee and Charlton.

The work will be carried out over a five-week period while stores remain open with “minimal disruption expected”.

Asda senior director of construction and implementation Ian Brackenbury said: “We are always looking at ways in which we can improve the overall experience for our customers and this program is one of the many ways we are actively doing that.

“Starting with our supermarkets and superstores, this significant investment allows us to upgrade our stores by launching new and exciting services, whilst making significant improvements to the existing components of our established stores.

“This program marks another exciting milestone moment for us on our journey and underpins our continued commitment to ensuring Asda is set up for long term success.”

The move builds on the significant investment made during the first quarter of the year to convert all 470 convenience stores acquired from EG Group and the Co-op to Asda Express.
