Exertis has relocated its Basingstoke offices to new premises on the same Chineham Business Park estate.
The move from Elmwood to Ashwood consolidates the company's current 380 Basingstoke employees into one refurbished building which has the capacity to support the continued growth of the company.
The Ashwood location will house all Exertis commercial departments - sales, marketing, purchasing and the technical teams.
Paul Bryan Exertis UK&I MD, said: "The requirement to move to new premises is indicative of how the Exertis business has developed over the last few years across our four technology areas - IT, mobile, home and supplies.
"We now have a facility that meets our needs today and can cope with our strategy for continued growth."
Exertis also has offices in Altham, Harlow, Stoke-on-Trent, Elland and is building a National Distribution Centre in Altham (a new 650,000 sq.ft. logistics facility).
In addition, it owns Computers Unlimited which has UK offices in London.
