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.
