The divestment follows a strategic review at DHL Parcel UK.
The MBO team has been backed by the private equity wing of Mercia Asset Management which is taking a stake in the business.
DHL’s UK Mail postal business is not part of the deal. It will continue to provide downstream access services to UK Mail Digital, and UK Mail Digital (also known as iMail) will continue to provide hybrid mail services to UK Mail’s customers.
Barber has worked at DHL/UK Mail for nearly 15 years. He was appointed as general manager of iMail, which became UK Mail Digital, in 2008 before rising to commercial director and then managing director of the operation.
He will become CEO of the new business.
Barber commented: “I am delighted that Mercia Asset Management have backed me and my team to conclude this deal which gives us the chance to take this business forward to new levels. We have some great plans which will unfold over the course of the next few months.
“I would also like to thank DHL for its support throughout this process and we look forward to continuing our close relationship into the future.”
UK Mail Digital is headquartered in Ryton-on-Dunsmore near Coventry. The business runs a fleet of Riso and Konica Minolta digital presses.
The operation works with clients from SMEs to large corporations and offers marketing communications services, business document process outsourcing and digital communications.
Peter Fuller, CEO of DHL Parcel UK, said the £525.5m turnover group’s focus going forward was on delivering its strategic network plans “in our core markets of e-commerce and mail”.
“The two businesses will continue to support each other’s products, and we look forward to ongoing collaboration to deliver market-leading mail services for our respective customers,” he added.
DHL is part of Germany-headquartered Deutsche Post DHL Group.
The group said that UK Mail Digital customers will be "seamlessly transitioned" to the new business with DHL's support and there would be no change to existing arrangements or services.
The deal is expected to complete on 1 October, when further details will be available.
