Firstly, does the connection from the router to the BT VDSL modem have to be a point-to-point RJ45 link, or can it be a switched link via an existing home LAN?
Secondly, on the day of the installation, will be the BT engineer just check connectivity from the BT modem, or will he be expecting to check from behind the router?
If someone could help answer these, I'd be really grateful. Only got a few days to the install now!

I found this page, describing some entirely different hardware, that suggests it is certainly possible. The primary aim there is to be able to get a computer to be able to access the Modem's GUI - which I'm sure we'd love to be able to do with BT's hardware, but it seems to be locked down. However, the mere existence of the page suggests that what you want to do is plausible. Method 4b, I'm guessing, is closest to what you want.
Though you probably don't want to set it up like that when the BT guy turns up.
The BT engineer will usually check a sync speed out on his dedicated tester (so ask him for the stats when he does, as you have no other way to extract them); he'll also want to check the sync on the modem. However, they don't seem to want to perform anything from the router for Plusnet, although they sometimes seem to for Infinity installs.

BT will do their tests to confirm the line is working but will not set-up or test the router supplied by Plusnet - although many of them have been trained on the BT supplied routers and they can set them up. However they should allow you to test it and confirm everything is working before leaving.

As far as I understand it (which is limited for PPPoE, but less so for generic ethernet & IP comms), the layer beneath PPPoE is plain bog-standard ethernet - and so just need to go to somewhere with a MAC address.
I guess the real question is whether there is any interaction between router & modem to identify the modem as the "way out of here". If the modem just acts as an ethernet bridge, then I agree that you don't want your internal LAN traffic (whatever payload is in the ethernet frames) bridged out to BT!

I'd actually go with PV's suggestion on my network.
Computer -> Switch -> Firewall -> BT Modem
If I moved the BT Modem to the switch (ie the rest of my network):
Computer -> Switch <-BT Modem
Then with no IP address, the Switch would never send anything except Multicast and the like packets to it. It is a switch after all.
The Firewall doesn't worry about that, I've told it which port to send the PPPoE stuff over. I can't/don't do the same with the switch

Honestly, not being able to use my LAN to connect the router/modem is not ideal for me. I was really hoping to be able to use this method. I wanted to locate the modem near the primary phone socket, which in turn is near an Gb ethernet switch, which is an extention of the network from my office. I don't have a dedicated RJ45 point for the modem in this room. In the office (where the current router and a secondary phone extention are), I was under the impression I couldn't locate the modem here, as it needs to be connected to the primary phone socket. I'm wondering now if it's possible to convert the secondary phone extension to the primary socket, so I can locate the modem there.
I'm also not planning on using the Netgear router PN sent, as I want to use my own one which has all the ethernet WAN support built in (Billion BiPAC 7800N). Lots seem to be using this without problem, so I'd like to keep it.
If necessary, would BT switch the sockets over? I can't imagine this is a big task.
Finally, is the standard BT VDSL modem wall mountable?

I'm using a Billion 7800N; I didn't even upwrap the PN-supplied Netgear.

Was there a problem in locating the Billion where the ethernet switch is?
I guess you can't replace the switch with the Billion (as it won't be Gb), but you could colocate them, and plug the router into that switch, rather than leaving it in the office.

...or... actually use the PN-supplied netgear at the position of the existing master socket, between the fibre modem and the existing switch, with wireless disabled if that's an issue. And let the Billion be just an access point still positioned in the office.
Unless I'm missing something.

If I locate the BT modem in the lounge, as already stated, I can't use the 5 port ethernet switch to connect it to the LAN, as it won't work over a switched network. If I locate the modem in the office, I can easily connect it to the Billion via CAT6 flylead, but would have to get the secondary phone socket made the primary and vice versa as the modem has to connect to the primary socket (again, so I'm lead to believe).
Hope this makes sense, and explains why I'm a little limited on where I can connect things!

Your current master socket is in the lounge. Let BT install the fibre modem in there, and also install the PN-supplied Netgear in there. Configure the Netgear so that it does not do wireless, and connect it via Cat5 to the gigabit switch in the same room. So the Netgear will only be there to convey traffic to/from the internet (which can't travel faster then 40Mb), and to do DHCP.
In the office, connect the Billon's WAN RJ45 socket to the Ethernet cable from/to your lounge, and configure the Billion so that it is only an access point/bridge* (can't remember the precise term, but basically so that it acts as a wireless access point, and a gigabit switch, but does not do DHCP (or ADSL)).
That should leave you with gigabit/wireless available in exactly the same places as now. The disadvantages are that you have the Netgear box switched on all day, and you use up one more RJ45 socket on the switch in your lounge.
*assuming that it can be persuaded to take on such a humble role. It looks like it can, but I haven't tried it.

While the Netgear is only 100Mbit, it doesn't matter, as it's purely used to/from the internet, which is slower.

When you say connect the Billion's WAN port to the uplink to the lounge, I assume you mean the EWAN port? Does the EWAN port function differently in AP/Bridge mode? I wouldn't expect this to work as a standard Gb ethernet port, as it's primarily designed to connect to PPPoE devices.
I will thank you personally though for your input into trying to make sure my FTTC install goes according to plan. If only I could use a switched connection between the Billion and the VDSL modem, I wouldn't be worrying about any of this!
