Just 2% of advisers in the Tenet network have gone restricted, after the firm encouraged members to remain independent.
Although it did not wish to "shoehorn" advisers into maintaining an independent proposition, Tenet has been one of the more vocal advocates of independence among networks, arguing remaining so was not as "onerous" as first thought.
Distribution and development director Keith Richards said the adviser's preferred business proposition should determine their regulatory status, not their network.
"Tenet has no intention of trying to shoehorn adviser firms in any specific direction," he said. "We believe we have a responsibility for presenting advisers with the facts to allow them to make their own informed choices regarding advice and regulatory status - whether that be independent, restricted, appointed representative or directly authorised.
"For many advisory firms, the longer term move to a fee and service based proposition will ultimately create a more stable and profitable business model but of course many are just starting the early stages of transition.
"The unintended consequences of RDR have yet to be fully realised and the true impact on the wider industry will no doubt unfold during the next three years."
About 10% of its investment advisers have de-authorised post-RDR, Richards said the majority had planned to do so - either switching their attention to non-investment business or principals who had decided to take on a managerial role.
