I've had a pretty good experience with them so far. I'm yet to push ahead with the advice, but I was impressed at the level of knowledge and the way in which I was handled. I also heard quite a lot of negatives on other Financial Advice companies, and was referred to these guys by quite a few UK expats using their services.
I won't say who I'm dealing with online, but if you'd like a recommendation let me know and I'll PM you his details.
