Thats the thing, the copper line in the property is already there, its all underground too. But for some reason they couldn't find the existing duct so had to run new ducting and cabling for the fibre.
If they have already installed new ducting and pulled cable though then it may be that the 10m length you have is all you are going to get. Though you could try asking them to pull a longer length.
Regarding the question of CSP, you have had different answers on here - some are saying that OR will install an internal CSP and then run new fibre from there to the ONT (in which case you are presumably a happy bunny), and others say that they have/are having installs without a CSP (in which case it seems you have issues).
If you do these have issues then there are two potential solutions:
1 - (preferred) get the ONT installed somewhere where you don't really want it, then run ethernet cable yourself to your optimal location for the router
2 - go to fs.com or a similar site and get a length of fibre extension, and then move the ONT to your preferred location. I have read (on the Ubiquiti forum iirc) that some have found this works for them, though it may not for you (and you may be in technical breach of some T+Cs somewhere, who knows). If you want to go this route let me know and I will go and try to find the link to the person who had success.
