Waitrose customers will no longer have to stay in for their food deliveries as the supermarket will become the first to send delivery men into their homes while they are out. An “in-home” delivery service, in which front doors are being fitted with “smart door locks” to give drivers access to customers’ homes to unpack groceries while they are out, is about to be trialled. Delivery men will be fitted with chest cameras so customers can be sure they are not stealing their items or nosying through their drawers while they are out, and customers have the option of requesting the footage afterwards.Similar schemes have already proved popular in the US and Scandinavia. Initially 100 customers located in South London will be offered a free smart lock, which usually cost £190, as part of the Waitrose “While You’re Away” trial.

Archie Mason, head of business development at Waitrose & Partners, said: “There is certainly an increasing demand among our customers to make shopping with us even more convenient to fit around their busy lifestyles.”Rather than waiting for a delivery or trying to put everything away, it gives customers more flexibility to use that time differently, including more time enjoying cooking and eating the food they’ve bought.”The concept of in-home delivery has started to prove popular in other countries so we are keen to establish if there is an appetite for it in the UK.”Nigel Fisher, managing director of Yale UK, said: “Working with Waitrose & Partners to develop the UK’s first in-home delivery service is an exciting premise for Yale as we look to understand how smart products can enhance daily lives as well as protecting your home.”Customers can find out if they are eligible for the trial or can register their interest in future rollouts by visiting wya.waitrose.com. Yale’s smart lock system allows access to different people at different times by using temporary codes Credit:Yale Waitrose delivery drivers will only be allowed to enter customers homes if they have been with the firm for six months or longerCredit:John Lawrence It works by fitting customers’ front doors with Yale “smart lock” technology and setting a temporary access code which is then sent to Waitrose via a secure app.The code is then sent to the delivery driver’s device at the time of arrival at the customer’s home and is deleted once the delivery is complete.The driver will put goods that need to be refrigerated and frozen away and leave other groceries on the kitchen counter, or as instructed by the customer. To qualify customers must commit to a minimum order of £25 and a minimum of six deliveries, although Waitrose said it would review this after the trial. Waitrose said it anticipated being able to make the service available to more than 1,000 customers in spring next year depending on the success of the trial.
