No one has said anything about fibre, any obligation to provide service in the short term is premised on it being a copper pair, potentially from a cab that has FTTC and the distance from the property to it being short enough to benefit, so FTTC may be available , it’s unlikely that FTTP will be available.
Lineplant is just a term for underground and overhead equipment ( ducts, cable, dropwires etc ), depending on how the property was serviced previously ( overhead or underground ) then the original method may be reinstated....however, it’s likely that if you raise an order , because the address is ‘matched’ to existing lineplant , then the order goes through, and even if you ( assuming you place the order in person rather than on line ) point out that extra work may be required, the chances are the customer service rep falsely reassures that it will be OK on the day, but the OR tech turns up, discovers work is required and passes to OR survey/planning to come up with a solution, that’s where the potential delay could be, on the other hand , the previous service may be serviceable and easy to reinstate ( assuming whoever told you the property had service previously was correct )
Its not that unusual orders failing like this, imagine a ‘regular’ property that had ‘BT’ service in the past but has used a cable provider for the last decade, and the ‘cable’ service installer cut the BT service off, saying you will never need this again....new occupant moves in , doesn’t want to use ‘cable’ but an Openreach based provider...obviously when the OR installer turns up there may well be a delay as the existing cut cable is no longer any good and replacing it needs more work than the installer can deliver.
Only if the property is quite remote from any existing OR lineplant and has never had service before would excess construction charges be a worry.
