I ordered the Home::1 FTTP Speed 1000Mb/s down, 115Mb/s up service with static ipv4 and ipv6 addresses for my home server setup. I had to contact them for information regarding getting the fibre line ran in through my loft to an upstairs room where the server rack was located and they assured me this was possible. Installation day came and the engineer installed it exactly how I asked and I used my own modem. Everything just worked without issue.
I would highly recommend them.
