I have never had any problems with them, although honestly I have not had cause to deal with any problems. They are significantly cheaper and a fixed monthly payment so the more you ave with them the less it costs, a fraction of the fees with HL. I am a bit surprised at some of the feedback on this forum but they are a low cost provider so need to make some allowances. Their website is not as slick as Hl but it is functional enough.

I'm a long-term iii customer and have just set-up an ISA account for my youngest son. Called into iii customer service and he handled my queries quickly and professionally. Very happy with the service provided and the speed of response in getting my questions resolved.

Having recently invested with iii I had cause to request a few details about different aspects of my investment that I id not understand. Using the secure message system within my account I was very pleased with the speedy response and the clarity of the explanation. Excellent service keep up the good work.

I called for some info on draw down and the call was answered immediately and the information I received was excellent

Despite no reply to my secure message of last week , your response to my last minute call was good and service was swift. So 0 out of 10 for the non online message reply , but a big 10 for the response to my telephone call. Many thanks.

Transferred my cash ISA from HSBC to III. Filled in one short to-the-point form, sent it in, and a week or so later the ISA was transferred over. Was able to get advice from III over the phone - the III representative was very helpful and guided me through the process detailing key dates etc.

The query I had reference the QF was answered very concisely and with complete clarity and the solution to my query.

What a pleasure to use this platform for my ISA , quick transactions , clear detail , good communication, would recommend to anyone.

I have been using Interactive Investor for investing in stocks and shares for 8 years. The website is excellent; it is easy to find information about securities and funds and many funds are available with a big discount on the initial investment. Trading is very straightforward and holdings, statements, trading records etc. are instantly available online and very clearly laid out. The cost is very competitive at £10 per trade and frequent traders are rewarded with a £5 per trade rate after a fixed number of trades have been made in a month. There is a monthly charge of £20, however in return users are given two free trades per month. In addition, fund rebates are made to users (instead of II taking commission, I believe) and these rebates can exceed the monthly charge. To deposit and withdraw funds, users register a bank account. Deposits are made by bank card; II retain the details and can debit one's account whenever necessary, e.g. if there is insufficient cash available to pay the monthly charge. If money is withdrawn it takes 3 days to reach your account; I did find that a little annoying as most bank transfers are practically instantaneous these days using the Faster Payments process. Contact with II can be by phone or secure message. I did not find this necessary very often but on the odd occasion I used either method I was very satisfied with the service. (Response to secure messages used to take several days but there has been a noticeable improvement in the last few years). All in all if you are looking for a trading platform I would have no hesitation in recommending Interactive Investor.

Its clear from reading all the negative reviews here that there many of the unhappy people just haven't understand what iii offers (and in the cases of people who don't know that there is a quarterly charge they clearly haven't read things probably - it is made very clear on the website) Quite simply if you want amazing levels of customer service and no quarterly fees you can go elsewhere to people like hargreaves lansdown. However although you might not be paying a quarterly fee you will be paying far more in ongoing portfolio charges. iii does not have the best user interface or fastest customer service. However it is the market leading in offering a low cost investment platform which will have a far more dramatic impact on your overall wealth over time. If you want to be in control of your investments and have the lowest amount of fees you can't beat iii.

I opened an ISA account with iii recently. Found the website a little awkward to navigate initially but once got used to it was ok. When I contacted customer services for advice on how it all works have been given accurate clear advice and when have emailed them i have always had a reply within 48hrs. So have been happy with the service. The quarterly charges include the same value of trades, so if you trade on the regular savers day at £1.50 its good value to build up a portfolio over the long term. I would happily recommend to anyone considering starting up a stocks and shares ISA, i did however move a small pension into a SIPP elsewhere purely because the value I wanted to move into the SIPP was below what iii would accept. So to sum up over all very pleased.

I've just opened up a trading account and ISA/SIPP and am in the process of transferring in stocks and shares from another provider. So far the service has been very efficient, friendly and informative. The charges are very competitive for a fairly large SIPP and ISA and if trading just a few time a quarter it becomes even more interesting. Its early days but I'm not sure why the helpful and friendly attitude of the staff so far should change.

My wife and I have been iii investors for many years and have had no problems. They are significantly cheaper than the Hargreaves Lansdown new charges for larger portfolios. We are infrequent traders so don't mind the £10 trading charge and the quarterly rebates more than cover the £80 annual charge. Their online messaging service always gives answers within 48 hours.

No problems from me either. Been using for about 3 years now buying funds and shares and never had any problems.

I would definitely recommend this site to others due to the wealth of information contained between the site and its bulletin boards.

Never had to deal with staff so cannot comment there but I personally commend the two stage levels of security with the amount of fraud and cyber-crime
