I got my MAC code today, and ordered BT using online ordering.
I chose the '4months free when switching from Orange' plan and the years £120 lump sum up front for telephone line rental.
Will get my home hub delivered next friday and get 'switched' that day.
I hope the installation will be easy - everything else has worked fine so far
PS - got myself a gmail address and switched all I need to that already so that bit is sorted in advance (thanks Neil)
