Very interesting do you find the administration okay with that provider? Good website etc? I will definitely take a look at that.
Administration... it's fairly basic, I can't see any problems with it particularly once you know what menu takes you where and so on.
You can do regular (monthly) investments for a reduced trading fee, it's simple to turn that on and off. They've switched to taking the management fee monthly (used to be quarterly) so you just need to make sure you leave enough in there til the next dividend comes in, assuming you're going to buy something that pays one.
Bear in mind I make websites and databases, so my ability to make things work or navigate through things is often better than most - but also that my tolerance for junk is lower - meaning that I'm not the right person to ask this question of. From my perspective simple is best, there isn't much fluff once you're logged in. But then literally all I want to do is log in, add cash, set up a regular investment. So it works for me!
I wouldn't use them for investment advice - not that they are necessarily bad per se, but of course they want you to trade more in theory. Or maybe they just want more money to manage, I don't know.
One other good thing is that they don't email you. I've no doubt opted out of everything, but since whenever that was - I don't remember getting any junk from them whatsoever.
NB the regular investment doesn't have to be regular, you can just use it once and disable it, change the amounts, etc. Basically it's just a batch buy to save on the trading fee.
