Thanks for your interest in the thread.
The issue is not so much about sharing cables. Yes VM need to pull in individual cables for each VM customer, then remove all the cables that currently serve them. These currently feed off VM box on my property, they have been buried in my garden, fixed to my fence and nailed to my property ,chipped out a grove in my concrete path, then make good the damage.
I'm still waiting for some positive move from VM on how they are solving this issue. At the moment, I have given them time to respond but no positive proposals have been received from VM.
I suppose next steps are to sue for criminal damage to my property, and charge VM a monthly rental for a wayleave and continued use. My rental value currently I assess as £100 per month.
