M&S starts automated food warehouse build

M&S has started construction on a £340m automated national distribution centre in Northamptonshire, marking the retailer’s largest investment to date in its food supply chain.

The 1.3m sq ft facility is scheduled to open in 2029 and will support more than 1,000 jobs. Once operational, it will serve more than 200 M&S Food stores, adding capacity as the business works to double the size of its Food operation and strengthen availability across a larger store estate.

Construction began with a steel-signing ceremony involving M&S, Gist, Prologis, Winvic, and local representatives. Gist operates as M&S Food’s logistics arm, while Prologis is involved in the development. The site is being built to increase capacity, reduce long-term cost-to-serve, and improve the reliability of store replenishment.

Automation will sit at the centre of the warehouse operation, with the facility designed to support faster deliveries and simpler stock and fill processes in store. The investment adds more than storage capacity; it changes how product moves from inbound supply through distribution and into food aisles. That connection between warehouse execution and store labour has become increasingly important as retailers try to protect availability without allowing distribution costs to erode margin.

The building is also being designed to achieve a BREEAM Outstanding rating and will be positioned as M&S’s leading Plan A warehouse. In food logistics, sustainability targets are now tied closely to infrastructure decisions, including energy use, vehicle charging, refrigeration strategy, rainwater management, automation density, lighting, and transport integration.

The Northamptonshire project adds another major asset to a logistics network already being reshaped around automated capacity. M&S has also bought the former ASOS warehouse in Lichfield, a separate move that showed how automated warehouse assets are being absorbed into retail supply chains rather than left tied to their original e-commerce use case.

Fresh-food supply chains put particular strain on distribution models because shelf life, chilled handling, promotion cycles, store opening patterns, and availability targets all compress the margin for error. A distribution centre serving more than 200 stores has to manage volume while keeping replenishment frequent enough to avoid empty shelves or excessive back-room stock.

Across Europe, retail logistics is moving toward larger, more standardised, and more automated platforms. Decathlon’s warehouse standardisation programme with Skyfleet shows how retailers are using technology to harmonise fulfilment across multiple markets. M&S is taking a UK food-led route, but the operational direction is similar: greater automation, higher throughput, and more predictable warehouse performance.

The labour dimension is also difficult to ignore. UK warehousing continues to face wage pressure, recruitment competition, and uneven availability of skilled operational staff. Automation does not eliminate the need for people, but it can reduce dependency on manual movement in repetitive, high-volume processes and allow labour to be deployed into exception handling, engineering, maintenance, and site control.

Opening in 2029 gives M&S time to phase the facility into the wider Food network, but it also means the building is being designed for a grocery market that will demand stronger carbon reporting, more detailed stock visibility, tighter service levels, and greater resilience against supply disruption. A £340m automated food distribution centre is therefore a long-term operating decision, not simply a property expansion.

For suppliers feeding the M&S Food network, the project will eventually alter intake patterns, delivery scheduling, and the rhythm of product movement into store. For the retailer, the test will be whether the Northamptonshire site can combine scale and automation without creating a rigid network that struggles with the volatility built into modern grocery demand.
