Asda’s Sales and Market Share Decline Amidst Growing Competition

By the Editorial Team · Wednesday, June 24, 2026

Asda’s sales dropped 3.6 percent year-on-year to £4.2 billion, causing its market share to fall to 11.5 percent and bringing it closer to rival Aldi, while the retailer reported nearly £1 billion in annual losses for 2025. This decline highlights intensifying competition in the UK grocery sector, with rivals like Lidl growing strongly and overall market sales rising due to high promotional activity.

Asda experienced a decline in both sales and market share over the 12 weeks ending June 14, highlighting ongoing challenges for the UK’s third-largest supermarket chain. According to data from Worldpanel by Numerator, Asda’s sales fell 3.6 percent year-on-year to £4.2 billion, while its market share dropped to 11.5 percent from 12.1 percent. This decline places the retailer closer to German discount grocer Aldi, which has increased its market share to 10.7 percent.

The figures were released shortly after Asda disclosed annual losses nearing £1 billion for 2025, alongside debts totaling £3.1 billion. Allan Leighton, who resumed the role of chairman in 2024 to spearhead a turnaround, has focused on competitive pricing strategies in an attempt to regain market share.

In contrast, overall sales within the UK’s major supermarkets rose by 1.6 percent to £36.1 billion during the same period. Retailers benefited from unseasonably high temperatures in May, which boosted demand for summer-related products. For instance, sun-care product sales surged 128 percent, and fresh beefburger sales increased by 40 percent. The start of the football World Cup further intensified promotional activity, particularly across categories such as beer, cider, crisps, and chilled pizzas. Promotional activity was reported to be at its highest level in five years in June.

Fraser McKevitt, head of retail and consumer insight at Worldpanel, noted that nearly one-third of all grocery spending is now on promotion, emphasizing the fierce competition among retailers for summer shoppers.

Among Asda’s competitors, Lidl exemplified strong growth, with sales rising 8.6 percent to £3.2 billion and its market share growing to 8.7 percent from 8.2 percent. This increase came shortly after the German discounter surpassed Morrisons to become the fifth-largest supermarket in Britain. Tesco’s sales saw a modest rise of 1.2 percent year-on-year; however, its market share slightly decreased to 28 percent from 28.1 percent amid heightened rivalry in the sector.

Asda noted that a significant portion of its sales stemmed from non-food items, which Worldpanel’s data does not capture, describing this as a “clear competitive advantage.” Despite efforts to reverse its decline, Asda continues to face intense competition as it seeks to stabilize its position in the British grocery market.
