Chase Templeton has acquired intermediary firm Best Go Private, which was founded in 2010 by former AMII treasurer Graeme Godfrey and wife Lucy.
The latest deal adds £3.1m in annual premium income to the consolidator firm, bringing its years' total of API to £12.4m.
Best Go Private's client base includes nearly 250 SMEs who will have their accounts administered from Chase Templeton's SME Centre of Excellence based in Darwen.
The around 550 individual clients will have their accounts served from the company's offices in Bridgwater, Somerset.
Godfrey said: "I was naturally keen to secure a good and fair financial return but I was equally concerned to ensure that our clients would continue to be well looked after.
"I was impressed with Chase Templeton's record in the acquisition and integration of businesses like ours, that they understand they are buying goodwill and that, therefore, if they don't deliver on service then they've bought fresh air."
Chase Templeton has spent over £18m in purchasing brokers, books and IFAs, completing over 40 deals, the firm currently has above 35,000 corporate and individual clients with over 110,000 lives.
Jeff Tate, mergers and acquisitions director at Chase Templeton, said: Graeme is particularly well known and respected in the industry, not least for his active participation on the AMII executive committee.
"In Best Go Private he built and led an exceptional, service led company which offers an excellent fit with our own business model."
