New Build

Building a new house as we speak. In the garden of our existing house which has virgin fibre terminating on what will be the boundary wall between the two properties. 

Fibre goes to the brown box and coax into the house for the TV/broadband.

I am told that the fibre should be able to support more than one connection so presumably that would be coax from the brown box (don't know what it's proper name is). As this is the last house on the road VM can't simply tap in to a toady box with an unused fibre)

Have tried to contact Virgin by phone to confirm this is the case but end up going round in circles.

What I also need to know is what cable(s) I need to run in the house. Bearing in mind we are building a highly sealed "Passiv" house this ideally needs to be done during the construction phase to limit the number of penetrations into the sealed/insulated parts of the house. (More problematical after completion). And I presume VM are not happy to use generic (even if perfectly good coax) not supplied by them. And in theory the electrical contractor could use suitable coax and flip the existing connection into the new house but clearly that would breach my VM contract terms and not a realistic consideration. Otherwise it would leave the new house without a high speed connection until Open Reach go live with Fibre to premises next year)

Is there a number I can contact directly to discuss this and obtain the correct cabling?
