Its chief executive Simon Taylor said the achievement is a testament to the group’s hard graft.
He added: “We have always strived to offer more to brokers than our competitors, investing heavily in technology and working hard to offer the very best products on the market.
“We look forward to continuing our successful partnership with SimplyBiz.”
Martin Reynolds, chief executive of SimplyBiz Mortgages, said: “We have dealt with Uinsure for a number of years but 2014 will be seen as the year that they came of age with our members.
“The sharpness of pricing, the commission sacrifice and Defaqto rating all helped contribute to a greater engagement with our members.
“The introduction of a dedicated national account manager at the end of the year has also increased the head office relationship.”
