The John Lewis Partnership has published its weekly sales figures, which demonstrate a climb in sales for summer groceries at Waitrose, but a decline in fashion and home purchases at John Lewis.

Total divisional sales for Waitrose, excluding fuel, were up 7.2% and, in line with the warm weather, the food retail division saw shoppers buy a record amount of ice cream with sales up 74% on the same week in 2015. Outdoor living also benefitted from a record week with an increase of 65%.

For John Lewis, however, the heat wave resulted in a slowdown with sales totaling £73.3m – a decrease of 4.3% on the same week in 2015. Biggest hit were Fashion and Home categories, which were down 7.0% and 11.2% respectively. The drop in footfall resulted in a slow week for larger ticket items, whilst the start of the school holidays saw a drop in school wear purchases.

Electricals and Home Technology fared better, with a rise in sales of 6.4% - unsurprisingly this was largely attributed to home cooling products such as fans and air conditioning units.
