Interactive Investor vs Fidelity - products

Both Interactive Investor and Fidelity have ISAs, General Investment Accounts, Junior ISAs and SIPPs, with Fidelity also offering a Junior SIPP. It's worth noting that with the Junior ISA and Junior SIPP, Fidelity doesn't charge a fee. Interactive Investor also has a dedicated trading account, which allows people to invest in shares, funds, investment trusts and ETFs. The trading account is particularly good for those looking to save money on foreign exchange charges as it allows investors to manage money in 9 different currencies.

Interactive Investor vs Fidelity - minimum investment

Interactive Investor requires a smaller minimum investment than Fidelity, with no minimum lump sum to open an account, or £25 per month as a regular investment. Fidelity, meanwhile, has a minimum investment of £1,000, or £25 per month. However, investors in Interactive Investor also need to factor in the monthly charge of at least £9.99 - which includes one free trade per month - as well as the charges for additional trades, starting at £5.99 per trade.

Interactive Investor vs Fidelity - fees

The relative cost-efficiency of Interactive Investor and Fidelity comes down to the amount you are likely to invest. If you have a large investment pot, Interactive Investor's £9.99 monthly charge becomes good value, particularly if you don't intend to make more than one change to your portfolio each month, meaning there are no additional charges for trading. Fidelity, on the other hand, has a sliding scale of platform fees, with a cap of £45 for those with investments under £7,500 who have a regular savings plan. It also doesn't charge a fee for its JISA or Junior SIPP.

Summary: Interactive Investor vs Fidelity

The choice between Interactive Investor* and Fidelity* will largely be driven by the amount you are looking to invest and the types of products you are looking to invest in. If you are specifically looking for a Junior ISA or Junior SIPP, Fidelity is a good option as it doesn't charge a fee for those products. However, unless you commit to at least £25 per month in its regular savings plan, you will need to make a lump-sum payment of at least £1,000 to open an account.

For Interactive Investor meanwhile, the monthly fee starting at £9.99, which includes one free trade, represents good value for those looking to invest larger sums. The Company Account and Pension Trading Account options are also relatively unusual and so will prove attractive to those seeking those particular features.
