One of the largest appointed representative (AR) businesses within Openwork is to leave the company after failing to agree contract terms.
Blueprint joined Openwork at launch in 2005 and currently has 85 advisers.
But the company has failed to agree terms to a new contract with the Zurich-backed multi-tied network.
Openwork said the arrangement suited a new strategy of putting profitability ahead of headcount.
Marketing and proposition director Philip Martin said: "‘While it is always disappointing to see businesses leave us, the reality is that Blueprint's decision will have no significant impact on our bottom line.
"Our strategy will remain very much focused on building long-term relationships with high quality businesses, whatever their size, provided it is of mutual benefit.
"Chasing adviser numbers does not work and our recruitment policy accordingly centres on what firms can deliver in terms of quality of advice and profitability as opposed to headcount."
More than half of people over the age of 55 see financial security as a top priority in retirement, yet a third allocate more time to buying a new car, research from Legal & General (L&G) has found.
