I had noticed that the copper had been cut … and had , erroneously, thought, must have been cut previously, because the work shy git has left the 66.
Again, report to the ISP you ordered the FTTP from. It IS acceptable to use the UG copper to pull through the new fibre …
BUT, before this route is used, the installer should explain what they may have to do it, and agree and confirm with you , that you have no working service on the copper.
Received a letter just the other day ..
