I received my broadband kit today but sadly I'm unable to use it right away due to the lack of a virgin media wall socket.
I currently reside in a rental property, so I assume that I'll need to get in contact with my landlord first to make sure they're happy about someone coming out to install one for me?
if Vm's system has allowed a self install there has been an install there in the past - they know no more than that and internal boxes may have been removed for whatever reason but it would seem reasonable that permission has been granted previously so may not be needed
however some checking on your part of what is or is not there may be useful
not all installs have an internal box
start outside and look for the external wall box - 6" square ish usually on wall facing road or pavement - brown or grey usually - follow any cables that come from it and go inside - if there are non look inside opposite external box as they may just have drilled through wall - as said it may just be a cable rather than an internal wall box
if you find a cable you need one of these to attach the cable that came with the quick start kit
