Thanks Ribble, Yes I see that a new cable would be great and could solve that problem.
I neglected to state, sorry, that the cables in our area which are not getting anything like Superfast speeds and nowhere near 10Mb are supplied by cables which are buried directly into the ground for most of their distance.
The lack of ducting and poles makes installing G.Fast problematic too, BTO have to decide to create 2km of new ducting in the ground, or get wayleaves to erect new poles (which some NIMBY may take offence to). All that work to serve one group of 8 properties and another group of +16 properties does not sound very economical. Providing power might be the least of the issues.
It might well have been common practice in rural areas for cables to be dropped straight into the ground without ducting. So this scenario might be more common than expected, BTO know the truth of the matter.
A fixed wireless connection to the G.Fast node from the cabinet or the exchange may work better in this scenario, no new cables or poles to install.
