Intrinsic, the advice unit of Quilter, has been renamed as Quilter Financial Planning.
The move follows parent Quilter’s managed separation from Old Mutual.
The Caerus network brand has also been replaced as part of the move.
Currently, the rebranded business’ adviser headcount is over 3,900.
Quilter chief marketing officer Michelle Andrews said: “Quilter has a deliberate focus on trusted face to face advice.
“It’s at the heart of our brand and our business, so the transition of our advice network to the Quilter brand is more than a name change; it’s a demonstration of our commitment to advice and advisers.
The rebranded business includes Quilter Private Client Advisers, which was set up to serve HNW clients.
Last month, Quilter Private Client Advisers added £211m in assets through the purchase of three financial planning firms.
Quilter Financial Planning also includes Charles Derby as well as Lighthouse.
Charles Derby was snapped up by Quilter this February, while Lighthouse was bought by Intrinsic in a £46.2m deal last month.
Quilter Financial Planning CEO Andy Thompson said: “As our business is evolving our brand is as well, and the power of a strong and trusted brand should not be underestimated.
“The Quilter brand will allow the network advisers to enhance their relationship with their clients by demonstrating the backing of a strong FTSE250 listed business, while still maintaining their individual brands.”
