We're there!
The guy arrived around 8:15am, and I thought there was going to be a problem as despite all the notes being sent through about requiring a copper trained installer, he wasn't, and really didn't have a clue about connecting the Fibre to the existing gigabit wiring.
So, I grumbled a bit, not that it was his fault, then he made some phone calls (and I spoke to one of the previous guys who'd been out), and after about half an hour, another engineer turned up who was copper trained, and has managed to wire things up as I wanted.
So, now I have Full Fibre up and running at an average of about 107Mbps on Speedtest.net, and I still have my old copper landline working for the time being. All the wiring was internal, so NO DRILLING!!
