It is a private road, have they contacted you and the neighbours to arrange permission to dig up the road or is there a grass verge (which they prefer to dig if they can)?
They will provide a connection POT to the boundary of your property, it looks but like the top of a water stop cock. After that, it is up to you if you want them to bring the fibre across your property and into the house.
Having Gigaclear available does not stop Openreach providing you FTTP in the future.
So far I have been on Gigaclear for about 3 weeks and so far so good.
Gigaclear FTTP 300Mb
Three HomeFi 15 to 20Mb.
PlusNet Unlimited Fibre an unreliable 3Mb
