Starting off life over 200 years ago as part of HM Stationery Office, this Sheffield-based office supplies giant has had to pivot quickly in 2020, with its homepage currently promoting branded face coverings, home printing solutions and laminated signs. It has a dedicated tech webstore offering PCs, comms and print equipment. A lack of fresh accounts means we have had to rank Banner based on dusty old calendar 2018 accounts, when it posted revenues of £191.9m.
