Am I right in presuming that you have not yet moved into you new home?
That message is displayed when there already is an ONT connected to a lit fibre at the address and is stating what needs to be done if another service is required.
I predict that when you move in, you will find an ONT powered up and ready for a service to be supplied by an ISP/CP of your choice. (Basically you have nothing to worry about.)
Correct
When I viewed I did not see a ONT so found it strange.
I saw a box that looked like the one in my current flat where the fibre is plugged into the ONT so looks like fibre is there but no ONT.
My issue is I work from home so having to wait 2-4 weeks for engineer will be difficult
So wanting to find out if its common for new build to have FTTP but no ONT pre installed.
