Thanks for all the replies. I know that fibre has been run from the chamber in our road to a chamber on the main road.
It seem that the overhead fibre is the most practical way to get fibre to the main road chamber.
My VM contract is up in May, so with bit of luck I'll have BT FTTP available and so some haggling to be done.
If we go for BT, I will just need to get sign off from the boss for the ?ONT? . That could be the trickiest part of the exercise. Do BT do relationship counselling?
LOL etc
