I don't specifically know anything about Cube bikes, but the specs on those that you linked look pretty good to me. The most important part is that the shop you go to is knowledgeable and not shady, and I've heard GREAT things about Chain Reaction...even here in the States. Apparently their customer service is top notch.
Most any bike in the dollar (pound? lol) range you're looking at are going to be pretty comparable, so you and your group really just needs to focus on what's right for each of you. For instance, your daughter might be more comfortable on a women's specific bike (or not). I'm sure, from what I hear, that the people at that shop will get each of you on the right bike for you.
