Marks & Spencer is closing its distribution centre near Warrington, putting 450 jobs at risk.
But a new distribution centre is to open at Welham Green, Hertfordshire. This will create around 500 new jobs.
At both sites, staff are employed by third-party partners. Workers employed by either DHL or XPO at the Warrington site are now in consultation over the future of their jobs.
“Closing Hardwick will help to remove some complexity from our network and speed up our supply chain," said Gordon Mowat, director of clothing and home supply chain and logistics at M&S.
"However, it was not a decision we took lightly and it is not in any way a reflection on the hard work and dedication provided by the teams on site. We will do all we can to support our partners through the consultation process."
Meanwhile, DHL has been appointed to run the new facility in Hertfordshire.
M&S said that the move would enable it to move products to stores faster and at a lower cost.
It is part of a wider strategy to simplify distribution, which also included the closure of a Neasden distribution centre.
