Fidelity FundsNetwork has expressed surprise over fund managers opting to raise prices in newly-launched clean share classes.
In a presentation to advisers, regional sales manager Paul Hendrick warned against a wholesale move out of bundled share classes and into their clean counterparts.
"Most of the bigger groups have now launched clean share classes, but look at how much providers are charging," he said.
"It's an unfortunate consequence that charges seem to be drifting up."
FundsNetwork would not be forcing advisers into clean share classes, though admittedly there was "a clear direction of travel," he added.
"Your existing assets can stay as they are: bundled share classes are not banned. They can't pay commission but there is nothing to stop you buying those funds and topping up the old bundled share class."
Platforms are split on how best to encourage advisers to move assets into clean share classes - one of the central tenets of Retail Distribution Review (RDR).
Cofunds has more than 2,000 available on its platform, compared to about 360 on FundsNetwork.
Last month, director of marketing Verona Smith said a wholesale move to clean was "the best way to get what the FSA wants in terms of transparency," though platforms are not currently obliged to do so.
"It is up to [managers] to agree their own pricing on their [clean] funds, and that's something we can't control," she said.
