Nutmeg has fairly high fees for users with balances below £100,000. With its four different portfolio options, you'll either have to pay 0.75% or 0.45% if your account balance doesn't exceed the £100,000 threshold. Investors with more than £100,000 will pay much less in fees (e.g., 0.25% or 0.35%). The answer to this question depends on your investment preferences.
