At least 20 advisers at Aegon-owned IFA Origen are set to lose their jobs as part of a company "streamlining" process.
A spokesman for Aegon says of the 72 positions it estimates it will cut, 22 will be financial consultants.
Origen says it hopes a number of redundancies can be achieved through voluntary arrangements as it strives to align the business with recommendations in the RDR.
Managing director Stephen Greenstreet says: "It is important Origen has a business mix that is profitable in all market conditions, and that we have a high quality team of consultants to take the business forward.
"This means taking some tough business decisions [but] it also means the business will be better positioned to move forward as we move into a new commercial environment created by the proposed RDR regulations."
Affected staff were told of the developments at 3pm today during a conference call.
As part of its plans, Origen will not renew the lease on its branch in Sidcup, Kent. All consultants based there will move to the London branch.
Parent company Aegon UK formed Origen in June 2004 by bringing together five of its specialist IFA businesses - Advisory & Brokerage, Aurora Financial Group, Elliott Bayley, Momentum Financial Services and Wentworth Rose - under one brand name.
Today's announcement follows a number of cost-cutting measures implemented over the last 18 months.
As well as outsourcing its product and fund research functions to OBSR, the firm has also centralised its paraplanning, group risk, new business processing and ongoing client servicing into its Farnborough office.
