UK Mail
It began trading in 2004, with Powergen as its first customer, and delivered its one billionth item of mail in October 2006. In 2009, its parent company, Business Post Group, became UK Mail Group to "reflect the growing importance of the mail arm". In 2015, problems caused by a new automated sorting hub had resulted in a loss in profit, and a share price drop.
In September 2016, UK Mail announced that it would be acquired by Deutsche Post DHL Group. By this time, the news media reported that the company had established "one of the largest integrated parcels and mail operations in the United Kingdom" The sale was concluded in December 2016, for US$315.5 (£243 million).
