Yorkshire-based Trustmarque is moving into new headquarters after its old digs became too overcrowded.
It said the move to new premises would allow it to continue its expansion while offering more space for training up staff.
"We currently have several vacancies across the UK and without this move we would not have had the capacity to accommodate them," said COO Mark Godliman.

The reseller claims to have doubled its headcount to 170 in the past three years, and had an eventful 2011, picking up cloud reseller Nimbus last May in a bid to bulk up its sector credentials.
According to group sales and marketing director Angelo di Ventura it continues to target further acquisitions as well.
It also shifted its southern base nearer the capital, moving from Windsor to Chiswick in West London.
