British Picnic Food Sales Surge as Grocery Inflation Slows 2026

British shoppers are snapping up picnic food as grocery inflation slows to its lowest rate in nearly two years. According to new data from Worldpanel by Numerator, the annual growth in supermarket prices fell to 2.1% in the four weeks to 9 August, down from 2.6% the previous month. This is the slowest increase since October 2024, offering some relief to consumers.

Picnic Food Sales Surge During Heatwave

The scorching temperatures across the UK have driven a remarkable shift in shopping habits. Sales of dips increased by nearly a quarter compared with the same period last year, while coleslaw and potato salad saw similar gains. Quiches, olives, and chilled finger foods also recorded significant sales increases, as families embraced the British tradition of "picky bits" for outdoor meals.

Ice-Cream and Frozen Treats on the Rise

With the heat persisting, freezer aisles saw a surge in activity. Shoppers made an extra 6.2 million trips to the cold section compared with last year. Ice-cream and sorbet products posted a 26% increase in sales, while frozen fruit soared by 48%. Soft drinks also grew by 15% as consumers sought to stay cool.

Grocery Inflation Slows to 2.1%

The slowdown in grocery inflation is a welcome development for households. The 2.1% rate is well below the 2.6% recorded in the previous month and marks the lowest level since October 2024. This moderation is partly due to increased promotional activity, with nearly one-third of all supermarket sales now coming from deals.

Deals and Promotions Drive Savings

As shoppers look to manage their budgets, promotions have become increasingly important. The 31.3% of sales coming from deals was the highest level this year. This trend is helping to keep grocery inflation in check, as retailers compete for price-sensitive consumers.

Average spending on groceries fell to £410 over the four weeks, a decrease of £14.24 from the previous period. This decline is partly due to the end of the football World Cup spending bump, but also reflects a shift towards more economical shopping habits.
