Old Mutual Wealth will operate as Quilter when it completes its separation from parent company Old Mutual and operates as a newly listed business.
The integrated wealth management business will operate in two divisions - advice and wealth management and wealth platforms.
It said the businesses within these two sections will be rebranded to Quilter over a two-year period following the separation from Old Mutual. Clients will not be affected, it added.
The advice and wealth management segment will include: Intrinsic, which intends to rebrand to Quilter Financial Planning, including Private Client Advisers, which will become Quilter Private Client Advisers; the multi-asset business, which will become Quilter Investors and Quilter Cheviot, which will retain its name.
The wealth platforms segment will include the UK Platform, which will become Quilter Wealth Solutions and the International business, which is to become Quilter International. The Heritage life assurance business will become Quilter Life Assurance.
The business said it is on track to list as early as possible next year, subject to regulatory and other approvals.
Chief executive Paul Feeney said: "Having two distinct but complementary segments will help us to continue to deliver good customer outcomes for new and existing customers. Our recently reported Q3 year-to-date flows demonstrate continued strong demand for our investment solutions and services.
"However, having individually strong businesses is not enough by itself to drive success. We are focused on ensuring the businesses work together to build better solutions and drive integrated flows.
"We very much look forward to listing in 2018 as Quilter. We believe that we have a compelling investment opportunity as we continue to deliver strong and sustainable returns for shareholders in our own right as a fast-growing, independent and publicly listed company."
