Jon Lewis sales rose 9.9% to £62.6m last week as it clocked up the best performance of the half.
Fashion grew 5%, with childrenswear up 11%. Nickolds said the “impact of the unseasonably warm weather was evident in outerwear and fashion accessories where trade was softer”. However, it added that this “looks set to change as more wintry weather arrives”.
The department store group said it benefited from “some pent-up demand following the recent warm weather and also the benefit of investment in new space”.
John Lewis opened three shops in the last four weeks. It also last week refurbished its Cheadle store.
Like-for-like shops showed a “significantly improved position last week”, as sales at Newcastle, Trafford and High Wycombe thrived in the week to October 15.
Nickolds said the retailer achieved a “stellar” result online, as sales surged 36%, driven by a “notable” uplift in web traffic.
He added: “We now find ourselves on the cusp of the Christmas sales build. Our combined focus will ensure we provide the most enjoyable shopping experience for our customers every time they visit us and capture every sale possible.”
