Just did some quick reading about free trade. They are an execution only broker; is this the best way to describe it? I’d like to try it, after I figure out how to send you a message! 
To be honest I’m not in a huge rush of giving up on HL. They came across a little expensive but since I don’t really trade a lot, the only fee I end up paying is their platform fee. That in itself is actually similar to what a premium free trade account would cost, to me personally. And since I can’t yet transfer isa and sipp to free trade, I may not be their ideal customer, just yet; and vice versa.
What I ideally want is just one single broker that I can fully trust, for example put all my investments including my own pensions with, and some good research apps, like the ones I outlined above together with many possible others. Would you use free trade as your main broker account or is it one of many brokers that you are using to diversify provider concentration risk?
