Advisers may have to fork out up to £175 every year to cover the cost of renewing the FSA's proposed Statement of Professional Standing (SPS) certificate.
Under plans in the latest RDR paper, advisers will need to obtain an SPS from an FSA-accredited body in order to continue practicing.
Although not stated in the paper, the FSA's Katharine Leaman says advisers will have to renew their SPS every year.
The FSA estimates the cost to advisers of obtaining an SPS from an accredited body will vary, but could be as much as £175 per adviser.
It will depend, the FSA says, on how much it costs professional bodies to meet its criteria to become accredited, costs it may then levy on advisers by charging to supply SPS certificates.
But the FSA says £175 may be a drastic overestimate for those advisers who belong to professional bodies that already meet its accreditation standards.
A bigger bearing on costs may instead come from the competition that develops in the "new" accreditation market, it says.
Many current professional bodies, including the Institute of Financial Planning (IFP) and the Chartered Insurance Institute (CII), say they will apply for accreditation powers.
The FSA says it expects their members will have the cost of obtaining the SPS document absorbed into their regular annual subscription fee.
Advisers who choose to remain non-members of professional bodies would need to "subscribe" to an accredited body for verification of their CPD, qualifications and code of ethics in order to receive the mandatory SPS.
Larger firms with many advisers who are not members of professional bodies will be forced to weather the extra bill.
Manager of the FSA's professional standards policy team, Katharine Leaman, says it is down to the accredited body how they charge.
"Some advisers won't pay as much for the annual SPS fee as they are already members of professional bodies which have told us the costs to them of verifying the Statement will be limited, as they have already done much of the work to get up to standard.
"Advisers who are not members and are so not paying any subscription fees to a body will incur costs to become a member of an accredited institution. I assume subscriber costs will be less."
Consultation on the professionalism paper closes on 24 September and the FSA will publish its final rules in a Policy Statement in December.
