Tesco Whoosh Sales Top £400 Million

According to Kawaldeep Anand, head of product for digital customer experience in Tesco’s grocery home shopping division, almost the entire Whoosh stack is built and run by Tesco Technology, from customer-facing apps to APIs and orchestration services. The service runs through Tesco’s existing app and website, uses Clubcard, connects to store-based picking systems and plugs into delivery partners including Uber Eats, Just Eat and Stuart.

The result is a rapid-delivery model embedded in the wider Tesco ecosystem, rather than a standalone business with its own technology estate. Tesco says that has allowed it to reuse engineering work across the group, feed innovations back into the main grocery business and scale without adding physical devices to stores.

That store-led model is central to the economics. Instead of relying on dark stores, Tesco uses its existing supermarket and convenience footprint as local fulfilment hubs, which gives it access to inventory already in place and keeps capital spending lower than a build-from-scratch rapid commerce network. Tesco has also adapted Whoosh for smaller-format Tesco Express stores, where staffing and workflow constraints are tighter.

The company says AI is now helping both software delivery and operations, including scheduling tools that created an extra 100,000 online delivery slots in the week before Christmas and helped attract more than 250,000 new customers in the same period. For investors, that points to a route to incremental revenue without a proportional jump in fixed costs, a key issue for grocery operators under margin pressure.

Whoosh’s growth also shows how q-commerce is changing. Tesco says the service is moving beyond emergency top-up baskets toward broader same-day shopping, with larger basket sizes and later fulfilment being tested in selected areas. That widens the addressable market and suggests the fastest-growing part of grocery delivery may increasingly overlap with mainstream online shopping rather than sit apart from it.

Tesco shares closed at 19.29 on Sept. 4, above their 50-day moving average of 19.03 and 200-day average of 18.47, while the relative strength index at 65.2 points to firm momentum but not yet extreme overbought conditions. The stock’s recent climb reflects investor interest in Tesco’s ability to defend market share and extract more from its digital platform as online grocery remains a strategic battleground.

The next test is whether Tesco can keep scaling Whoosh’s coverage, store participation and basket size without eroding service levels or economics. For rivals still running separate rapid-delivery stacks, Tesco’s model raises the bar on how q-commerce can be funded, integrated and made durable.
