You need to be within service range of the connectorised block terminal (CBT).
The CBT would have been installed to the property that requested the FoD connection. Immediate ‘neighbours’ served by that CBT would also be able to order (native/ordinary) FTTP. Can you see any pole mounted CBT that would have been installed for the neighbour?
Unfortunately having the fibre run past you is not good enough.
That fibre could also be for an EAD (leased line) service, so not necessary associated with or used to deliver FTTP.
