The trading fees that you pay at IG will vary depending on what you are trading. With that said, the platform does not charge any commissions when trading non-stock CFDs. The spread betting department is also commission-free. If trading stock CFDs, you'll need to pay a variable commission that averages 0.10%. However, there is a minimum trading commission to consider. For example, buying and selling less than £10,000 worth of UK stock CFDs will attract a minimum fee of £10, which is expensive.
