Marks & Spencer has extended a services deal to cover security administration, software asset and system build management and system disposal.

The five year £19m IT managed services contract will adhere to Europe’s WEEE environment directive and will see Computacenter Services will manage 7,000 servers, desktops and laptops at six sites.

Damone Quigley, head of infrastructure and application services at Marks & Spencer, said the contract means lower and predictable IT service costs for the retailer.

The deal is part of a stated three year £500m technology refresh programme at M&S.

Last month the retailer signed a four-year managed service contract with Logicalis covering networks and infrastructure development across M&S’s 591 UK stores and regional offices.

In August it agreed a three-year systems systems integration contract with IBM to refresh its in-store technology and systems, including the implementation of the Beanstore point-of-sale application from software supplier PCMS.

Back in May its chief executive Stuart Rose said the retailer would be spending £150m this year revamping its IT systems and said similar levels of spending were also slated for 2008 and 2009.
