FTTC is sold by many ISPs, and available for nearly all to sell if they choose.
Infinity is BT Consumer's main version of it, though for estimates below 15Mbps they offer "High speed broadband with fibre". (That is purely so the figure they can advertise for Infinity customers is high, as it doesn't include anyone under 15Mbps).
Sky offer FTTC in most places - did they offer it to you? Probably calling it Superfast Broadband. As do TalkTalk.
Plusnet and EE are the other big ISPs with it. I think Vodafone are getting going with it as well.
Some smaller but good ISPs are (alphabetically) AAISP, Aquiss, IDNet,Pulse8broadband, vivaciti, uno, Zen. AAISP are expensive, but possibly the best support in the industry.
Pulse8broadband are quite popular at the moment, and Aquiss have
an introductory FTTC offer running to 1 March.
Aquiss, Pulse8, vivaciti and uno have much lower line rental and call charges than the big boys, who use it as a cash cow to subsidise their "free" inclusive TV and the like. AAISP offer a line only setup for broadband (no landline calls but VOIP available at a small extra cost) as well.
My line is with Pulse8 and costs me just over £14 per month as I usually call out on my mobile plan minutes. My broadband is with AAISP as my usage easily fits in their Home::1 FTTC package.
The indispensable man or woman passes from the scene, and what happens next is more or less the same thing as was happening before.
