Tesco is set to trial its new one-hour delivery service Whoosh as it attempts to stop rivals taking over the on-demand grocery sector.

The Big 4 grocer will test the service on households near its Willenhall Express store in Wolverhampton, and hopes to expand it in the future.

Shoppers will need to spend a minimum of £15 plus £5 on delivery, bringing Whoosh in line with the prices of Deliveroo, which is used by at least five major supermarkets.

It is unclear why Tesco has chosen not to partner with the multi-billion startup.

“Customers are telling us that they would welcome the addition of a 60-minute delivery to their door option as part of our online grocery service,” Tesco online managing director Chris Poad said.

“We’ll use the pilot to understand how Whoosh could work best for both our customers and our colleagues.”

The news comes after Sainsbury’s and Waitrose cemented their partnerships with Deliveroo last month.

Sainsbury’s announced it was expanding its Deliveroo trial to 100 stores across the UK.

Two weeks later, Waitrose revealed it would quadruple its number of stores with Deliveroo availability, creating 400 jobs in the process.

The grocer is also scrapping its own delivery service, Rapid.
