Just to be clear, either way there is a cost. The cost of advice is either paid by the client in product charges or through fees paid by the client. It is important not to present the commission option as either "free" or less expensive than paying for advice by a fee.
A typical broker in Ireland today will receive 3% commission for setting up an ARF plus another 0.25% to 0.5%pa ongoing trail commission. For a €150,000 fund that is €4,500 upfront plus up to €700pa ongoing.
The real cost of these commissions are disguised through allocation rates, bid offer spreads, early surrender penalties, and annual management charges which do not fully reflect the real cost of investment. But, these costs are built into the product charges and the client pays - however it is presented.
