Biba has called for "stricter guidelines" on the Financial Ombudsman Service's remit once the FSA regulations are enforced.
Biba's working party on the FSA's CP187 met last week to discuss the issue. Working party chair Chris Arter said: "The ombudsman is at present not accountable. Clearer guidelines are needed.
"We have asked for a dialogue with the ombudsman because there is a perception that it appears to be biased towards the claimant. Whether that is fact or fiction we don't know, but we are trying to get some cases and get a dialogue."
CP187: Insurance selling and administration & other miscellaneous amendments was published in June and incorporated feedback on CP160.
Arter also said that the FSA's rules on inducements, in particular the controversial 'grossing up' issue, was still unclear.
"The FSA has not decided on the inducements side of the issue which is very worrying. What is worrying is that the FSA can say any inducement is unfair, other than base commission."
The working party will present its findings to the next Biba board meeting in September.
