Any initial advice fees will be charged as before, with these payable by you from your own resources or in some cases facilitated by the product provider, though not by commission. You would need to agree to these fees in writing before the investment is made.
A typical unit trust investment may have the current charging structure:
1.50% per annum of which:
0.75% pa goes to the fund manager
0.25% pa goes to the administrator or platform for administrating the investment
0.50% is payable to the adviser (who may or may not offset this against their ongoing fees)
Rather than this charge being bundled together into one single charge of 1.50%, it will now be split into its component parts, depending on the service you require in the future. This will make matters more transparent than at present. Please note charges may vary from fund to fund and company to company, so this should only be regarded as an example.
