John Lewis announced a 13 per cent sales increase for the same time last year as the partnership continues to grow.

The department store, which has 39 UK stores, said three trading directorates and both channels posted positive increases as the recent cool down in temperatures attracted people back into stores.

Dino Rocos, Operations Director, John Lewis said: “Among the fulfillment channels Click & collect has continued to support this growth with collections up 51 per cent on last year‘s total. Our Distribution Centres continue to manage this growth in the premium delivery offering, with a strong service performance.”

JohnLewis.com also delivered a strong result, with sales up 24.7 per cent from the year before. Electricals showed the largest year-on-year growth once again (24 per cent) with juicers announcing triple digit growth.

Results from Waitrose were more modest, with total sales for the week up 4.1 per cent (excluding petrol) although the grocer has outperformed the market for more than four years in a row, according to Kantar data. Food to Go sales were up 15 per cent as the school holidays affected shoppers habits. Flowers and home baking ingredients posted strong increases.

“This achievement (that Waitrose has outperformed the market for four years in a row) is testimony to the efforts of each and every Partner across the business”, said Mark Price, Managing Director, Waitrose.

He added: “We faced particularly tough comparatives with the equivalent week last year when we had the first sustained period of hot weather of the summer and the excitement for the Olympics had started to build.”
