How to win in UK quick commerce: the retailer perspective

The changing model of UK quick commerce

The model driving that growth has changed. Store-based fulfilment is replacing dedicated dark-store networks, allowing retailers to use infrastructure, stock and labour already embedded in their businesses. 

Stores give grocery retailers the right to compete, but integration, execution and sustainable economics will determine who wins. 

Stores are quick commerce’s critical infrastructure 

For UK retailers, quick commerce generates additional revenue from existing infrastructure rather than requiring a separate network.

Tesco provides the clearest evidence of the opportunity. Because its stores, inventory and fixed assets were already in place, Whoosh required only £7 million to £8 million of initial capital expenditure. Yet it is on track to generate more than £500 million of sales this year, after growing 37% in the first half. It operates from more than 2,100 locations, reaches over 75% of UK households and contributes to profit growth. 

Other retailers are applying the same advantage. Sainsbury’s quick commerce sales grew 27% in its first half and the service is available from more than 1,400 stores. Co-op recorded 24% growth, with coverage across 90% of its estate. Morrisons supermarket and convenience networks support both broader baskets and urgent local missions. 

Across the industry, retailers are shaping fulfilment based on store format. Convenience stores provide proximity and suit smaller top-up shops; supermarkets offer wider ranges and larger baskets. By extending Whoosh into more than 250 larger stores, Tesco is broadening rapid delivery beyond forgotten items and blurring the boundaries between quick commerce and conventional online grocery.

Proximity must be matched by execution 

A nearby store enables rapid delivery, but not reliability. Customers expect the products shown online to be available, orders to be picked accurately and substitutions to be appropriate. 

Sainsbury’s links quick commerce performance to strong store availability. Investments in inventory systems, electronic shelf labels and AI-supported replenishment can improve accuracy and release colleague time for other activities, including picking online orders. 

Picking capacity also becomes more important as volumes rise. Tesco is considering store reconfiguration, automation and partial dark-store picking in high-demand locations. Existing stores enable efficient entry, but retailers must adapt them as order density increases without disrupting store shoppers or scheduled online operations. 

Aldi’s Deliveroo trial illustrates the trade-offs from limited integration. Riders pick, scan, pay for and deliver orders, allowing Aldi to participate without increasing colleague workload. However, IGD’s observed shop highlighted the potential weakness of this light-touch approach: slower picking when riders are unfamiliar with the store, unavailable products without substitutions and weaker rider economics as baskets become larger. 

Aggregators can therefore offer a low-cost route into the channel, but participation is not the same as winning. Integrating inventory, systems and picking gives retailers more control over speed, availability and service.

Use aggregators without surrendering the relationship 

Aggregators offer large audiences, delivery capacity and access to shoppers beyond retailers’ own apps. Yet retailers that rely entirely on them have less control over pricing, fulfilment, data and loyalty. 

This has led to the emergence of a hybrid operating model.  

Tesco has added Uber Eats and Deliveroo alongside Whoosh, using the platforms to extend reach rather than replace its own service. Clubcard integration allows customers to access member prices and earn points, helping Tesco identify and reward shoppers entering through third parties. Tesco reports that early sales through its aggregator partnerships have been largely incremental, with many shoppers new to the retailer. 

Sainsbury’s combines aggregator partnerships with Chop Chop, while Morrisons operates Morrisons Now alongside its aggregator partnerships. Iceland offers another middle ground: customers order through its website or app, stores pick the goods, and third parties complete delivery. 

Retailers do not need to own every capability. However, retaining control of the proposition, customer relationship and order preparation can protect differentiation, even where the last mile is outsourced.

Speed alone will not secure demand 

As quick commerce becomes widely available, retailers are competing through range, value, availability and mission relevance.  

Co-op is naturally aligned with top-up and immediate-consumption occasions. Iceland is targeting forgotten meal ingredients, lunchbox products, snacks and cravings. Larger stores can extend the channel into meal solutions and more substantial shops. 

Quick commerce can also create value beyond the basket. It can recruit customers, increase app visits, deepen loyalty participation and create personalisation and retail-media opportunities. Tesco’s use of Whoosh sponsorship, targeted notifications and Clubcard integration demonstrates this wider ecosystem potential. 

These benefits cannot compensate indefinitely for weak order economics. Tesco provides the strongest evidence that rapid delivery can contribute to profit. Elsewhere, retailers have remained guarded on profitability and order economics, while Sainsbury’s focus is shifting from rollout towards operating efficiency and customer experience. 

Winning retailers must establish whether orders are incremental, control fulfilment costs and balance affordability with sufficient margins. High product mark-ups and fees risk narrowing demand; excessive subsidy creates growth without sustainable value. 

Store networks have given established retailers the upper hand, but they are only the foundation. The winners will connect proximity with accurate stock, productive picking, relevant ranges, loyalty and disciplined economics. 

Speed may attract the first order, but reliability, value and control will determine who wins the channel over the long term.
