The firm, a corporate member of the Institute of Financial Planning, said advisers were under "enormous pressure" to ensure they were treating customers fairly.
As well as RDR, the Financial Conduct Authority has announced any adviser working with clients in legacy investments will have to agree arrangements which meet adviser charging rules from April 2014. Cash rebates from fund providers and platforms will end in 2016 which will get rid of trail income.
As a result, advisers should be restructuring their proposition in order to avoid reduced profitability when the changes come into force, says Parmenion.

Richard Mein, managing partner at Parmenion, believes CIPs are a way for advisers to operate profitably post-RDR.
He said: "Advisers are failing to implement propositions which handle the upcoming changes and preserve the value in their existing relationships. Only modern CIPs offer the scalability to allow advisers to operate profitably at post-RDR pricing, whether their firm has £10m or £10bn under management.
"It's imperative that advisers readdress their clients' needs across the board in order to retain their income stream."
