Chase Templeton is expanding its Lancashire headquarters to accommodate a new Sales Centre of Excellence and additional staff due to join the business in the new year.
The move comes just two years after the broker relocated to its current home having outgrown its previous premises in Blackburn.
Since then it has more than doubled staff numbers in order to manage acquisitive and organic growth which have seen the business expand to manage in excess of £145m in annual premium income.
Richard Holden, commercial director at Chase Templeton said: "We are making a significant investment not just in additional office space, but recruitment, training and technology. All are vital if we are to maintain and build upon our impressively strong retention rate, which runs at 90 percent-plus, and the customer service which underpins it."
The new building will home a dedicated Sales Centre of Excellence with all back-office functions retained in the existing offices.
This will complement the firm's business hub in Bromley and existing offices in Darwen and Bridgwater respectively.
The company is also in the process of recruiting 15 additional staff who are joining the business this month and in early 2016, further bolstering the current payroll to 128.
The new recruits will include four account managers and two newly created posts of business retention manager and a micro-SME team leader.
Holden added:"Because we are an acquisitive business it is particularly important that we invest in the people, skills and technologies necessary to deliver the level of customer service which drives satisfaction and retention.
We already know such investment generates significant returns with clients we now serve being overwhelmingly satisfied and loyal.
"They also report feeling more confident in our ability to deliver on service and value because of our size and strength, an increasingly important factor within not just the PMI sector but the wider financial services market."
