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.
Simple and transparent charges
Unlike percentage-based fees charged by many providers, with ii you will always pay a low, flat fee. This can add up to real cost savings as your wealth grows.Â
Start on our Core plan at £5.99 a month and upgrade when you want access to a wider range of benefits - or when your portfolio grows above £100,000.
All price plans come with access to our Stocks & Shares ISA, Personal Pension (SIPP), and Trading Account, along with a wealth of benefits. Whichever plan you’re on, you’ll have everything you need in one place - and at one price.
