Especially when BT know how many properties have a BT line, and if 80% have VM, then that's only around 20% (approximately 40 properties) possibly with a BT line. So a low take up because of the low amount of properties served, further reduced by those that are on VM, who may or may not move over.
Is it not other way round?
Current high takeup by BT means BT aready get line rental and possilby other subs related to broadband. So revenue growth potential = small.
Current high takeup by VM, rollout NGA then the amount gained from ex VM customers is much higher than converting existing to FTTC customers.
However if its a high BT takeup areas with little takeup from VM, and also high amounts of faults due to dodgy long lines, FTTC can be justified by reducing faults (although probably not almost removing them like FTTP).
