I don't know SFX, but I get the sense that it's somewhat downmarket and laddish -- that its audience is primarily young and male.
That could explain why not even Laurell Hamilton made it onto the list, but many female epic fantasy writers did. (Or maybe urban fantasy isn't as popular in the UK right now.)
There are plenty of male writers who didn't make that list -- like Jack McDevitt, Robert Sawyer, Robert Reed, Robert Charles Wilson, L. Sprague de Camp, Clifford Simak, and so on -- but pretty much every British writer of SF or Fantasy is there.
