UK Consumers Shift Spending to Picnic Staples Amid Heatwave

The UK heatwave has dramatically reshaped consumer shopping habits, with Worldpanel by Numerator reporting a 24% surge in sales for 'picky bits' like potato salad, olives, and coleslaw. Ice cream sales rose 26%, while frozen fruit sales soared 48%. The heatwave delayed evening meals, with 13% now eaten after 8pm, and increased demand for cold products by 6.2%. Discounted shopping drove supermarket promotions to their highest level this year (31.3% of sales), while post-World Cup spending slowed, reducing average basket size by £14.24. Online grocery sales surged 10% in value and 5% in units, outpacing in-store shopping. Convenience store sales hit their strongest growth in over a year at 3.6%. The trend suggests basket resets and potential short-term voucher returns as the season changes.
