The domed stuff is new (as in it wasn't in the catalog last year). I like it, having seen some at the trade counter, the range of colors is good. Yes, the smaller sizes are used very much in the same locations as Wiremold would be in the US. The UK tends to do more plastic than metal clad electrical gear now, it doesn't corrode as easily, but does tend to melt (but all of it's fire retardant).
