Take-home sales at the grocers rose by 4.3% over the four weeks to 26 January compared with one year ago, according to the latest data from Kantar. And January spelled relief for shoppers as grocery price inflation slowed to 3.3% over the four weeks.
With household budgets typically stretched at this time of year, retailers played their part in easing the pressure on purse strings. Fraser McKevitt, head of retail and consumer insight at Kantar, comments: “Supermarkets were dishing out the discounts this New Year, and consumers responded. Spending on promotions rose year-on-year by £274 million, accounting for 27.2% of sales – the highest level in January since 2021.
“People also turned to non-branded products to help keep costs down, with own label as a proportion of sales hitting a record high of 52.3% in January. Spending on supermarkets’ own lines was up 5.4%, helped by consumers buying premium own label products in the couple of days leading up to New Year’s Eve.”
Typically, shoppers have an eye on wellness, not just their wallets, at the start of the year – and 2025 was no exception. More than 10% of the average consumer’s January grocery bill was spent on fresh fruit, vegetables and salad, totalling £1.2 billion – £193 million more than in December. Nathan Ward, business unit director for usage and out-of-home at Kantar, adds: “Rolling into the new year, health tends to play a bigger role in our grocery choices. Over a quarter of take-home food and drink in January is chosen with health at least partially in mind, as shoppers tell us they want to eat less processed food and feel the benefit of fibre and vitamins.”
Protein products pulled their weight at the tills too as demand for bars, bites and drinks boosted spend on sports nutrition products. Sales for this category at supermarkets were 47% higher than last year, with over two million households buying these items during the month.
Sales of low and no alcohol drinks were 7% higher than last January, and 6.7% of households bought at least one of these alternatives. McKevitt comments: “It’s no surprise to see the low and no alcohol trend make its mark in January, but given some of the generational splits we have seen in grocery, it’s interesting that older shoppers are just as likely to take these products home as younger ones. Not everyone signed up for dry January though, with 49% of people buying an alcoholic drink this month – but this is a pretty big drop from December’s 76%.”
Lidl’s sales rose 7.4% over the 12 weeks to 26 January, making it three continual years of growth for the discounter, whose share hit 7.2%. Aldi accelerated for the third consecutive month with sales up 4.2% and its market share increasing to 10.2%.
Ocado was the fastest-growing grocer for the ninth consecutive month. Spending at the online retailer grew by 11.3% meaning it now holds 1.9% of the market. Joint owner of Ocado Retail, M&S has also seen a strong 12 week period of growth with grocery sales increasing by 10.5% in its brick-and-mortar stores.
Britain’s largest grocer Tesco gained the most share, its 28.5% hold of the market is 0.7% higher than this time last year, and it also saw its fastest rise in sales since April 2024 at 5.6%. Sainsbury’s outpaced the market at 4.2% sales growth, increasing its share from 15.7 to 15.9%. Morrisons has 8.6% of the market while Asda’s portion is 12.6%.
Convenience retailer Co-op returned to growth, with sales rising by 0.8% giving it a 5.2% share of the market. Waitrose maintained a share of 4.6% as sales climbed by 3.0%. Spending at frozen specialist Iceland was 1.0% higher, maintaining its share of 2.4%.
