Waitrose is making a major change to its late-night delivery service across the UK. Multiple reports say the retailer is adjusting the delivery window for customers placing orders for late-night slots. The change follows a trial in which Waitrose tested revised delivery timings in more than 50 shops during the World Cup period. The company’s approach is presented as a rollout based on results from that trial, extending the updated late-night delivery window beyond the initial test locations. While the reports focus on the operational change and the scale of the World Cup trial, they do not indicate specific impacts on product availability or costs in the information provided. The key message across outlets is that Waitrose is altering when late-night deliveries arrive, shifting from the previous schedule to a new delivery window that it has already evaluated in a large number of stores. The rollout is described as covering the UK.
