I think in areas with fibre coverage they will now only install fibre lines to homes, copper only of areas that haven’t been upgrades.

Regardless of the type of cable, I think there is going to be a lot of turmoil when PSTN is fully withdrawn in 2025. It’s one of the biggest tech transitions in the UK since the switchover from analogue to digital TV, but there doesn’t seem to have been anywhere near the public awareness effort. There’s still plenty of landline phone users, especially among older people and in rural areas.

I had a lot of trouble myself when I switched to a fibre provider that didn’t provide landline phone service, and had to explain to various elderly relatives that they would now have to call our mobile numbers. They would only call our landline from their landline.
