Groceries Online sales rose by 12.5%.
Tu Clothing sales declined by 2.1%, which Sainsbury's said outperformed a soft clothing market, while general merchandise sales fell by 6.3%, reflecting an ongoing programme to shift space allocation away from non-food towards food.
At Argos, sales dropped by 0.5%, as volume growth of 2.2% was offset by lower average selling prices amid subdued consumer spending.
The retailer added more than 5,000 new products to its Supplier Direct Fulfilled range during the quarter, bringing the total to 26,000 live products, and said it remains on track to launch a Marketplace later in the financial year.
Sainsbury's said it remains on track to deliver £1bn of cost savings over the three years to March 2027.
The retailer said facial recognition technology is now live in more than 55 stores, with up to 150 further stores planned before Christmas.
Sainsbury CEO Simon Roberts said: “Customers are looking for value now more than ever. We are consistently delivering outstanding quality at great value, so more people are choosing Sainsbury’s for their big weekly shop. This has driven an encouraging start to the year with continued volume growth and market outperformance.”
For the 2026/27 financial year (FY26/27), Sainsbury's said it continues to expect total underlying operating profit of between £975m and £1.07bn, and retail free cash flow of more than £500m.
It also noted uncertainty over the impact of the conflict in the Middle East on its customers and business.
