Yep, I was glad to get rid of my copper line as it went through the timber door frame I was about to replace. After a certain amount of an exchange is able to get fibre there’s a stop on offering new copper connections so even if you wanted a new analogue phone line in the future you’d be very unlikely to get it. The analogue copper network is due to be switched off by the end of 2025.
You can get the ONT for the new service put in anywhere within reason, but they’ll probably just clip it on the outside of your house to reach the room you want. If you’re happy running your own cable you may prefer a more discreet install and have the ONT near to where the fibre comes in (overhead or underground) then run your own CAT5 to wherever your router will live.
