Accountants from BDO Stoy Hayward were called in earlier this month at the agency which was turning over £15m a year.
A BDO spokesman said: “There have been no redundancies because staff have been transferred to other parts of the group.”
The BDO spokesman said Laboursite was a subsidiary of the WyseGroup which supplies workers across a range of industries including construction, power and logistics.
A WyseGroup employee told the Enquirer: “It’s been a bit unclear what has been going on but we have now been told that Laboursite has gone into administration and is now part of our WyseLabour division.”
WyseLabour places up to 2,000 operatives a day and has supplied workers to major contractors including Balfour Beatty, Skanska and Carillion,
