You do know Virgin is HFC, not FTTP, right?
So fibre to a street cabinet and coax from there.
granted coax beats voice-grade twisted pair (hence their being able to offer faster speeds than OpenReach FTTC and with none of the "up to" malarkey).
Also cable has more upgrades to come. DAA (Distributed Access Architecture) moves the DOCSIS PHY from the head-end to the cabinet and so improves your SNR (so you'll get higher levels of QAM) while making node splits easier (so fewer users share the same bandwidth). And given a "Node+0" setup (no amplifiers between the cabinet and the home) you can do things like full-duplex and/or extended spectrum (both are part of DOCSIS 4.0).
