FTTP installation question

I’m looking at moving from Plusnet (fttc) to BT Full Fibre. My current copper line emerges from a duct under the floor next to the main electricity supply. It runs for 4m under the floor and comes up in a cupboard to feed the BT master socket.
Would the BT engineer be willing to run the new fibre along the same route and install the ONT in the cupboard?
This would be ideal but I’ve read they won’t run cables under the floor.
There is easy access so I could run a conduit draw tape from the duct to the cupboard.

Also, Will I have to tell Plusnet I'm leaving or will BT do this?

If you provide a suitable tubing with a draw cord between the two points, I feel fairly sure the installer will be happy to oblige.

I presume there’s a good power supply in the cupboard where the ONT is to go.

Not sure about the CP’s informing each other .... someone else was will know, I feel sure.

They won't go under the floor but will use a draw line you've installed to pull a cable in if it's a easy enough job - they may want to put the splice point next to the duct and then run the internal fibre back through the route you've created under the floor.

Plusnet should get notice that you're cancelling as soon as they get the porting request for your phone number.

That's great. I hoped that would be the case.
I had installed a double socket in the cupboard before the doubts crept in so I'm now ready to order.

Thanks for your help

Thanks for your helpful reply.
I'll get the ball rolling now

It's quit possible that they will use the existing cable to pull in a combined fibre/copper new one.
If you get someone to gently tug the cable that goes 4M under the floor and and look at the other end to determine if it has been clipped or not, if not be easy to pull in new combined cable, or like you say install a draw rope.

New isp should tell old isp about the move, you don't

If the existing copper cable comes into the property via a duct then its unlikely the the Openreach engineer would use a combine fibre\copper cable.

As said by others a suitable tubing\conduit under the floor (without any sharp bends) would be a better option as opposed to leaving the fibre hanging loose.

I've just recently done the same move from Plusnet FTTC to BT Full Fibre and in my case BT notified Plusnet about the move of the phone line within a couple of days but because the FTTC broadband isn't moving they don't notify them about that.

In my case I called Plusnet and asked them to disconnect the broadband on the move date.

On the move date the FTTP install failed and I called Plusnet and even though the phone line had moved they left the FTTC broadband connected for me for a couple more weeks which was very helpful.

If I was doing it again I'd notify Plusnet and ask then to cease the FTTC broadband a few days after the proposed move.

I had FTTP installed yesterday and the installer was quite amenable to me running my fibre under the floorboards from the cupboard at the top of the stairs (following the same route as my upstairs ring main and then down through the ceiling of the front porch.

I did have the few floorboards that needed to be lifted to push through the fibre already loose. (either side of the cupboard wall , where the single cross joist is and above the porch)

It was actually easier for the engineer as saved him stripping off vast lengths of fibre to tack to the skirting board and drilling a hole through a thin lath and plaster ceiling is much easier than through early 1900's brick walls. The openreach box with the splice is then near ground level in the porch with the fibre coming down the external wall from the telegraph pole and back up through the ceiling.

The biggest problem with the installation was the 40 minutes waiting for the circuit to become activated - and the engineer then to notice there were 3 distribution boxes at the top of the pole not 2- 2 of which had been identically labelled and he had picked the wrong one.

Thanks all.
Openreach coming to run the fibre tomorrow and my activation date is date is 29th. Fingers crossed it all goes smoothly
