An update for anyone interested or who is following (unlikely!). Further to this, Area manager offered to bring the install forward a week, I said this was way beyond expectations but he insisted, and I got the feeling they wanted to see how the first install of the estate went. Install was meant to happen on 10th and I was happy to wait, but installer came out and installed the brown box on the outside and installed hub 3, but there was an issue. The fibre to coax converter should have had a green light but was showing red. So, again, James got the cable pullers back out the same day and he even came to my house to supervise. They had not tested the fibre when it went in as they "broke their tester that day", so a new fibre was blown through and a green light. It's been installed for a couple of days now and seems fine so far. So, a lot of work by a lot of people in 1 day. I am sure the doubters had good intentions telling me it would be an impossible/too expensive install and would "never happen", but I always say never take no from someone who doesn't have the authority to say yes and don't give up.
When I ordered the maximum speed available was 350. I asked James about that too and he said there was no reason why gig1 wasn't available, but they seem to default to 350 max for new areas, he is arranging to have that changed, said it should be done by Monday then I can upgrade to gig1. I hope there are no issues, as I only went with 350 because it was all they could offer, and had to take a SIM card and phone line both of which I will never use, so hope it will be straightforward to upograde and I don't end up paying more than I should have had I been able to order just the gig1 from day one. Also, I realise the hib 4 will be needed for gig1, but apparently you only get a hub4 when you place an order for that speed as there is a short supply of hub 4s. Despite all the issues people are having I actually hope I get the hub 5 for the 2.5 gigabit port.
