The new, high-tech 155,000 sq ft distribution hub has just "gone live", with an official opening planned for later in October.
More than £12m has been invested in the latest logistics and warehousing technologies at the Oak Meadow site, on Leicester Distribution Park, which will be home to 380 staff upon opening, with capacity to grow to over 500 people.
Staff and operations have been transferring over the past few weeks from Samworth Brothers Supply Chain's (SBSC) previous Meridian Park HQ to the new facility.
Ian Fletcher, Samworth Brothers Group executive director, said: "This new facility is an important milestone for Samworth Brothers. It gives us a new purpose-built supply chain home for the next 20 years or so in Leicestershire and has some important new capabilities that will help us develop the business further. When we open, we will have around 380 staff on-site, but there is significant room to grow over the next decade and beyond. In the future, if the site was working at full capacity, it could require a workforce of 500 or more."
