Sales at Waitrose rose a healthy 4.4% to £125.84m in the week to 30 July, boosted by the warmer weather and school holiday activities.
The chain said that baking was proving a popular way of keeping children entertained during the school holidays. Supported by strong promotional activity, sales in the category rose by more than 21%.
Picnic foods also saw significant sales uplifts with Waitrose’s Food to Go range up by 14%, while salads and prepacked delicatessen both saw sales increases of 11%.
The group added that its new Omega 3 enriched chicken continued to produce strong week on week sales since its launch this summer with sales up by almost 6%.

As sister chain John Lewis, sales rose by 3.4% to £76.62m, boosted by strong uplifts in the fashion (+7.9%) and electricals categories (+10.5%). However, sales in its home department slipped 7.2% as shoppers focused on the warmer weather rather than making big ticket purchases.
