Im having virgin media installed next week and want to get a few of my queries answered before I drop them all on the engineer when they come.
Your answers might depend entirely on a) the individual person who turns up to do the job and how helpful they are feeling at the time then b) how much time they have been allocated for the installation.
If you have an amenable tech, they might be willing for you to act as a helper and feed the cable through to you under the floor.
Alternatively, if you have the time before the install day, you could run in a continuous piece of conduit under the floor from front to back in advance of the tech visit. Fit a draw rope in the conduit so the tech can just tie on the cable and pull it through.
VM don't/won't install ethernet cables for you. You'd either need to DIY or get an electrician/computer/cabling tech to do that for you later on.
Your phone socket will be on the back of the VM hub (as this is how all new VM landlines are provided) in case that has any impact on how you connect your landline phone(s).
