My own view is that Financial Planning should be charged for on its own, by way of invoice. It should not be contingent on setting up a product, or be calculated by way of a percentage of assets. Financial Planning revolves around reviewing your life goals, setting some targets and optimising your finances. Much of that work has nothing to do with financial products. Paying off debt, keeping cash on deposit, gifting funds to children, building up reserves funds in your company might all be in your best interest, so you have to make sure the advisor is free to make those recommendations. If they are only paid through some form of % of assets, these recommendations are less likely.
Most of the better advisors charge 1% of assets as a Financial Planning / Implemention fee and 0.50% ongoing annual management fee. Others will just take whatever commission is offered by the product provider. Protection products pay between 100% and 180% of the first year premium. This increases your premium by 20% on average for the life of the policy, so that's what you are paying as a fee.
