What our customers think

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.

Great service and well designed website

I've used Interactive Investor for many years and find their administration efficient and website is easy to use. Highly recommend II five star service. I have a sipp isa and trading account with them and find their fees very competitive.

Analysis shows you could be better off by £44k over 30 years of investing in an ii Trading Account (General Investment Account) plus an ii ISA due to our low flat fees. This is just for illustration if all other factors were the same. The advantage of lower flat fees over time means that you could be significantly better off in the long run.

What our customers say

Having everything under one roof makes things much easier, as I no longer have to deal with multiple providers.
