DTE Risk and Financial Management has acquired commercial broker David Scott Insurance, its second acquisition in 18 months.
DTE said the acquisition of the Ashton-under-Lyme intermediary was worth £1m in premium income.
The operation will now be located in DTE's Bury office.
DTE managing director Mick McNulty said the company planned to expand its insurance division both organically and through acquisitions.
The company is set to write £15m in gross written premiums over the next year.
