That's going to be a difficult one. Virgin won't wire a property unless a contract is signed, as the install fee is part of that contract. Also any wiring changes needed after the initial install are twice as expensive.

Why difficult surely it ensures that the new person will use Virgin rather than another provider and I am happy to pay the installation fee that is reasonable. I notice that self install thingy but the previous provider was Sky (I hate them).
Virgin does Broadband only so I don't need a phone socket. They router attaches to a wall (I have one in my main res) I am concerned because the property is on the first floor so would they drill through the wall?
The easiest way is to install a cable duct between the entrance point and where you want the cable with a draw wire in advance of the floor going down. It makes life very easy for the installer and he will go out of his way to work with you if you present this option to him.
I have never had a complaint from installers, they feed and I pull. Also think where you are likey to want the terminations. Broadband and possibly TV locations. So if you have a study within the flat these are likey to be different. Also before fitting floors and depending on flat size, you may want to run cat 6 between a central area and rooms etc to provide local etherenet connectivity. Just in case your tennent is a tech bod and wants connected stuff thoughout.
