A chartered financial planner claims to have found evidence of attempts to maximise commission by both bank advisers and IFAs ahead of the RDR.
Joss Harwood, founder of Durham-based Eldon Financial Planning, said she has found examples of "questionable advice" and "mis-selling" in the portfolios of five new clients.
Three of the clients' previous advisers worked for banks, while two were independent practitioners, Harwood said.
She said that, in each case, the clients have been damaged by advice that appears to have been given in a bid to maximise commission.
From 1 January next year, product providers are no longer permitted to have any say in how much advisers get paid for their services. The move will effectively ban commission.
Harwood said: "Advisers at banks and building societies in particular have always been under an enormous amount of pressure to sell products, but my feeling is that this pressure has increased in recent months.
"Unfortunately, what we suspected might happen in the run up to RDR looks like it is happening and advisers are doing whatever they can to maximise their commissions."
Harwood provided details of two of the five recent cases that in her view demonstrate questionable advice and mis-selling.
"One client was sold investment bonds at 7% [commission]. A normal rate might be about 5%. Not only that, this lady was advised to cash existing bonds that were less than five years old, which in this case meant she incurred a 3% charge.
"A second client was sold a Prudential bond with returns projected at 6.3%. However, when we analysed it, the fund actually levied an annual charge of 5% per annum, meaning almost all the client's returns were wiped out.
"She had been unaware of the charge [and] it seems to me that not passing this information on was a deliberate omission," said Harwood.
The five clients that were sold these products were retired and elderly.
In February last year, the FSA issued an 'emerging risk' warning on investment advice firms, which it said may seek to maximise recurring income before the RDR deadline.
