The local "digital champion" for NNDC (North Norfolk District Council?) is involved, but I think he is trying to mislead me somewhat.
What they are not saying is that the cable they will replace will be fibre optic as they no longer lay copper cable, which might be some of the issue as Openreach do not have full fibre installed in our area yet.
I thought that if fibre was not available and the copper line was faulty it had to be replaced? I think I am being thrown a side swerve here.
