ISA Trading Comparison

*We've crunched the numbers: If you invested in both our Trading Account (General Investment Account) and ISA, after 30 years you could be better off by £45k. That's more than £1,000 difference a year, just for using us over another platform. Lots of things can affect your final figure. But the lower the fees, the more money you'll keep for yourself. This is just for illustration if all other factors were the same. Don't just take our word for it: check our working out here.

You can open an ii Joint Trading Account if you are looking to open a joint general investment account. Our Joint Trading Account allows you to trade our full range of investment options, including shares, funds, investment trusts and ETFs.

ii Stocks and Shares ISA

My husband has been holding Trading and Sipp accounts with II for over a year and is happy with it so I have just opened my ISA account too. I like its fixed subscription fees.

The best flat rate platform by far

Been an Interactive Investor for over 10 years now with both ISAs and SIPP products. Their flat rate fees save me an amazing amount of money for my large portfolios and really glad I moved to them. I self-invest using their comprehensive investment research information which is easy to understand, and their best picks and ready portfolios are really good to read and consider.
