Hi Baz8755,
A warm welcome and thanks for posting on our community forums. We can certainly understand your concerns about migrating our services from the traditional copper to via our fibre network.
The whole of the UK telecoms industry has committed to providing all telephone services via data connections by 2025 aligning with the government's plans for this to be completed.
We have a huge source of information about the changeover and this can be found on the forum page here, including information about battery backups for lines during power cuts, which will be available for our elderly, vulnerable and disabled customers, to ensure that they always have a phoneline connected, so that the emergency services can be called at all times.
If you have to relocate your handset, we can get a technician arranged who will discreetly re-wire the phone socket so it is closer to your router if this is what you require.
kind regards Jodi.
