The Broker Network has made its seventh acquisition of 2004, purchasing Mid-Pennine Insurance Services.
The purchase price is expected to be between £250,000 and £310,000. The final price will depend on Mid-Pennine's performance over the next two years.
Last year, Mid-Pennine reported revenues of £206,000.
Richard Guthrie will manage Mid-Pennine's office, based in Lancashire. All staff will be retained, along with the Mid-Pennine name.
Broker Network chief executive Grant Ellis said: "We're pleased that our plans for acquisitive growth are progressing so positively."
