A number of brokers such as Freetrade offer commission-free trading. However, it’s important to be aware of other costs. Freetrade, for example, charges £3 per month for its Stocks and Shares ISA and £9.99 per month for Freetrade Plus (which offers access to more investments). It also charges FX fees of spot rate +0.45% on international shares. In terms of investing in funds, some brokers such as Hargreaves Lansdown allow you to buy and sell funds commission free. However, these brokers generally charge an annual custody charge on fund investments. Hargreaves Lansdown, for example, charges 0.45% per year on fund holdings up to £250,000.
