There are no additional fees for holding investments within a Sidekick ISA. However, each fund has its own associated costs:
Global Stocks: 0.37% total fee (0.25% platform fee + 0.12% fund expenses)
Global Bonds: 0.35% total fee (0.25% platform fee + 0.10% fund expenses)
These fees are automatically deducted from your investments and help cover fund management and platform services.
