UK Christmas grocery sales were robust, fueled significantly by growth in online shopping. According to NielsenIQ (NIQ) data, total supermarket sales rose 2.5% in the four weeks to December 27, reaching £19.6 billion. Crucially, 29% of households bought groceries online, making e-commerce the fastest-growing channel and boosting Ocado to the top performer for the second consecutive year.
The Online Shopping Surge and Consumer Habits
Online’s share of total sales grew from 12.6% to 13.5%, a 9.9% increase in sales value. The convenience of booking delivery slots in advance allowed shoppers to do a ‘big Christmas shop’ online, including fresh foods. This category made up 32% of e-commerce sales. Consumers then supplemented with last-minute in-store visits for discounts and treats.
Mike Watkins of NIQ called it a “Christmas of cautious celebration.” While total market value grew, unit sales declined slightly (-0.2%), indicating continued price sensitivity. However, spend per visit rose 1.1% to £22.24, and shopping frequency increased by 1.4%.
Retailer Performance: Ocado and Lidl Lead
Ocado was the fastest-growing retailer at +12.8%, directly benefiting from the online surge. Among physical stores, Lidl led growth at +9.4%. Sainsbury’s (+5.7%) and Waitrose (+5.5%) also performed well, attracting new shoppers. Tesco (+3.7%) gained market share, while M&S (+4%) and Morrisons (+3.1%) saw positive growth. Asda was the outlier, with sales falling 6.5%.
Category Trends and Strategic Spending
Shoppers were considered but willing to treat themselves. Premium private label sales grew 5.6%, showing a desire for affordable indulgence. Impulse categories like snacks and confectionery grew 5.7%, and fresh foods rose 4.9%. However, beer, wine, and spirits saw a slight decline (-0.1%), possibly due to intense pre-Christmas price competition among retailers.
Sales peaked in the week to December 20 (£5.3bn), the biggest trading week of 2025. An extra trading day before Christmas also benefited large supermarkets.
Key Takeaways for Retailers
The data confirms the enduring importance of online grocery channels, especially for festive planning. Success required strong digital execution and the ability to capture last-minute in-store demand. Retailers with momentum entering the quarter sustained it through December, highlighting the competitive advantage of consistent execution.
