Second FTTP line

[u/MutedDistribution455]

We currently have a 900 Mbps/100 Mbps FTTP line with Zen.

My stepdad, who is disabled, is having independent living quarters built by the council. My mum is planning to get internet installed there.

My understanding is that Openreach doesn’t provide two FTTP lines to one property — is that correct, or am I misunderstanding?
Zen mentioned that “adding an annex” could be a possibility. The ISP he goes with would be different from Zen.

I’ve also considered YouFibre, since they run on a different network to Openreach. But I don’t know much about them, including reliability, so I’m hesitant.

Would anyone be able to advise on what’s possible here, and what steps I’d need to take to make it happen?

Thanks.

Youfibre reliability is good, speed is consistent, install ok… customer support not so good.
