Grocery price inflation in Great Britain has slowed to 2.1%, the lowest figure since October 2024.

That's according to data from market analyst Worldpanel by Numerator.

Figures for the four weeks up to August 9 show that shoppers are turning to promotions to keep their costs down, with 31.3% of sales in the four-week period including a deal, the highest level this year.

Overall, take-home sales growth of groceries slowed to 2.5%.

Despite the further easing of price rises, spending returned to more normal levels, following an increase in spending in the previous four-week period.

Shoppers spent £140 on groceries on average over the four weeks, over £14 less than the previous period.

Convenient "summer favourites" performed well in the most recent four week period, with dips up 23.3%, coleslaw up 23.1% and potato salad up 22%.

Chilled finger food rose by 15.1%, chilled quiche by 15.8%, and chilled olives were up 13.3%.

British shoppers also made an additional 6.2 million trips more to the frozen aisle in the four weeks than they did in the same period in 2025.

Frozen fruit was one of the stand outs, with sales up 48.1%, far outpacing the fresh fruit category.

Market share

Ocado was once again the fastest growing grocer, with sales up by 13.1% over the 12 weeks to August 9, compared with the same 12-week period a year ago.

Ocado’s share moved up to 2.1% of the market.

Lidl gained the most share in the period, moving up to 8.8% of the market.

Lidl also saw the greatest uplift in shoppers, attracting 736,000 more through the doors compared to this time last year. Lidl sales increased by 8.5%. 

Asda has yet to see sales growth in 2026, though they are "edging ever closer".

Accounting for 11.5% of the market, Asda's sales decreased 0.2% year-on-year. This marks the retailer's best recorded performance since March 2024.

Both Sainsbury’s and Morrisons gained 0.1% market share this period, at 15.2% and 8.5% respectively. Sales at Sainsbury’s grew by 3.5%, with Morrisons close behind at 3.3%. 

Take home grocery sales at convenience specialist Co-op, grew by 5.1%. Co-op now holds 5.5% market share, its highest since September 2025.

Britain’s largest grocer, Tesco, has a market share of 27.8%, with sales growth of 1.8%.

Aldi attracted an additional 488,000 shoppers in the 12-week period to August 9. The discounter now holds 10.7% market share, with sales increasing by 1.1% compared with the same period last year.

Both Waitrose and Iceland held market share stable this period, accounting for 4.5% and 2.3% of the market respectively.

Grocery-only sales at M&S increased by 15.9% over the 12 weeks.

Commenting on the latest figures, Sally Ball, business unit director at Worldpanel by Numerator, said: "With inflation slowing again, this marks the fifth consecutive month of easing prices."

"Shoppers are feeling the relief with 39% now feeling financially comfortable, marking the highest level of financial confidence since November 2021," Ball added.

"Among these households, 30% are more likely to prioritise grocery essentials over additional summer spending such as holidays and travel," she said.
