London Gateway is being developed in Essex by port owner DP World, 25 miles down the Thames from central London.
M&S said that locating its new 900,000 sq ft distribution centre here would remove millions of road miles from UK roads
Chief executive Marc Bolland said: “London Gateway will become our third large distribution centre in the UK as we transform our logistics operations into a modern and agile supply chain, fit for the future of M&S. As we become an international, multi-channel retailer, London Gateway will help us become more efficient by cutting costs and locating our supply chain closer to our stores and our international markets. It will also help us deliver against our Plan A objectives by removing road miles and emissions from our network.”
Subject to planning, Marks & Spencer will begin construction of the new facility in 2014. London Gateway port is set to open in Q4 this year.
