A friend of mine suggested a plan that takes a 1% administration fee (from the assets deposited) regardless of the type of investment you make (stock, bond etc.). This sounded quite high from my experience in US/Japan.
In my experience, you usually pay a fixed administration fee per account, the transaction fee when you trade the assets, and an administration fee on your assets depending on what you buy. If you aren't buying highly exotic assets like hedge fund, "Frontier market stocks" etc. then you usually end up with something like 0.1 - 0.3%. However my friend raised the point that ISA accounts may charge more because of the fact that it is an ISA account.
What is your experience with ISA accounts? Do you think 1% on total asset is a reasonable price?
