I was looking to use IG platform for a SIPP. Naively, I thought this would work like the "Interactive Investor" platform where there is a seperate (and all but anonymous) administartor in the background and I would be using the normal IG platform to buy and sell shares as I pleased. Just spoke to James Hay and they say that I cannot invest in shares direct myself - this can only be done using one of their fund managers. Therefore, I suspect that IG just get a referral and the relationship ends there. That is not attractive to me. IG need to take this in-house like Hargreaves Lansdown and Interactive Investor and then they would get much more business
PS James Hay's Glassdoor reviews and the other intenet reviews I have read on them since are pretty dire so I am probably well to steer clear.
