Helphire Group has begun the move to its new Bath headquarters, a former MOD site, following a £5m refurbishment.
It said the move would see the consolidation of staff in one site, as opposed to the three sites it currently occupies.
The final phase of the refurbishment and company move will be completed in September 2004, said Helphire.
The company is now located at Pinesgate East and West, Bath.
