The company was previously part of Compel, which 2e2 acquired in March last year, and is aiming to exploit its independent status to reposition itself in the market.
"The support of a large company such as 2e2 has been a real benefit to us from a financial point of view, but being independently owned means that both our existing and potential customers see us in a different light," said Martin O'Connor, managing director of Hamilton Rentals in a statement.
"By removing the link to a larger organisation, Hamilton Rentals can now move into channels which may not have been previously open to us," he added.
Hamilton has strategic alliances with a number of vendors including IBM, Hewlett-Packard, Sun Microsystems, Lenovo and Microsoft.
There had been no indications of a split with 2e2 management recently informing MicroScope that they were pleased with the performance of the rental operation.
Nick Grossman Business Development Director at 2e2 said that the management of Hamilton Rentals had decided to take the company forward via an MBO and wished the new owners well.
