I live 1 kilometre from the local exchange. For years we had ADSL2, which became steadily poorer and prone to faults due to the archaic 'twisted copper pair' joining us to 'Them'. There is a fibre cabinet sitting outside the exchange. That's as close as 'fibre' comes, leaving the corroding, failing 'TCP' cable to carry the service.
I've kidnapped passing Openreach engineers, and techies from cable installation firm Truespeed, and they all agree there is close to zero chance of us getting a decent fibre service this side of the Last Trump. So we use a fairly stable 4G wifi service from '3'..... until affordable satellite comes along.
