Marks & Spencer has signed a six year network services contract with Logicalis, renewing an existing agreement aimed at improving the efficiency of the high street retailer's IT infrastructure.

Under the deal, for which a value has not been disclosed, the wired and wireless networks of 700 M&S stores, its head office and other premises, and distribution centres, will be managed.

The agreement also allows M&S access to Logicalis' consulting and project management services, should it choose to take the option.

M&S said in May that it was on track to deliver £300 million in savings through the upgrading of its IT and restructuring of its supply chain. The rollout, being run by services supplier IBM, involves a major SAP rollout.
