Asda has announced a partnership with Ocado to overhaul its online grocery operations, replacing its existing technology platform with Ocado's system starting in 2027. The deal is a centerpiece of executive chairman Allan Leighton's turnaround strategy to reverse weak sales and win back customers. Asda will retain ownership of its fulfilment network while adopting Ocado's software for its website, app, in-store picking, and home delivery.

Allan Leighton's second act: betting on Ocado to fix online

Allan Leighton, who returned to lead Asda in late 2023, has staked his turnaround on a technology upgrade. According to the report, Leighton said: "We know that continued success in this highly competitive market is dependent on providing a positive experience for customers every time they shop." Partnering with Ocado, he added, will strengthen Asda's online offer and provide a consistent experience. The announcement comes after a period of weak sales that saw Asda lose ground to rivals like Tesco and Sainsbury's in the online grocery segment.

The move echoes Leighton's previous tenure at Asda in the 1990s and 2000s, when he helped turn around the chain. Now he faces a market transformed by online shopping and dark stores, and the partnership is his biggest bet yet on digital infrastructure.

What Asda keeps and what Ocado provides

Asda will retain control of its online operations and fulfilment hubs, but will replace its existing in-house systems with Ocado's technology platform. According to the announcement, Ocado's software will power the website and app, in-store picking, and home delivery. This is a split arrangement: Asda keeps the physical logistics, while Ocado handles the digital layer. The model is simlar to Ocado's deals with other retailers, though each partnership has customized terms.

One key detail is that Asda is not using Ocado's automated warehouses — it will continue to pick orders from stores and dark stores.. That means Ocado's technology will need to integrate with Asda's existing manual processes, a challenge that has caused teething problems for other retailers adopting the platform.

The 2027 switchover and the technology gap

The transition to Ocado's platform will not complete until 2027, leaving Asda with its current systems for several more years. That timeline raises questions about how much improvement shoppers will see in the near term. The report does not specify what interim upgrades,if any, are planned. Meanwhile, competitors have been investing heavily in online capabilities: Tesco has its own platform, Sainsbury's partners with Ocado's rival Wincanton, and Amazon Fresh continues to expand.

By waiting until 2027, Asda risks falling further behind before the new system goes live . Leighton acknowledged there is "plenty to do," per the report, suggesting the turnaround will be gradual.

Ocado's capacity: a growing roster of partners

Ocado already provides technology to several major grocers, including Marks & Spencer through Ocado Retail (a joint venture), Waitrose (via a previous agreement), and now Asda. Each addition strains Ocado's engineering and support resources. The report does not disclose whether Ocado will expand its team to handle the Asda contract or how the implementation will be phased. Industry observers will watch for delays or integration issues akin to those seen during the rollout with Waitrose, which experienced glitches .

The Asda deal also puts Ocado in an unusual position: competing for online customers with its own partners. Ocado Retail sells M&S products directly; Asda is a separate, potentially overlapping customer base. The report does not address this potential conflict.

What remains undisclosed: financial terms and performance metrics

The announcement did not inlude financial details of the partnership, such as upfront costs or revenue-sharing arrangements. Asda has not provided metrics on its current online performance — conversion rates, delivery coverage, or customer satisfaction scores that would justiy the overhaul. Those figures, according to the report, are absent from the press release. Nor did Asda specify how many of its stores will be equipped with Ocado's picking technology, or how many jobs might be affected.

Without these numbers, it is difficult for investors and shoppers to gauge the scale and speed of the investment. Leighton's strategy will ultimately be judged on sales growth, not just tech upgrades.
