Roll out seem to be going pretty smoothly in Cambridge. I just phoned up CS, and after a pretty long time on hold (no surprise there!) I got put through to a guy who was very helpful.. even going as far to suggest that I keep the old box and cancel it after 12 months to avoid paying the £75 install fee.. so ok, I only save £15, but it's better than nothing! I've only got one TV though, so it'll just be going in the cupboard..
Installation booked in for next Wednesday (17th) afternoon!
