1.3 million on Infinity
Another 200,000 spread over the other providers.
TalkTalk 73,000 fibre customers.
Sky is unknown, but will be growing as now advertising it on TV
Thanks for the clarification on the numbers, although I still find those numbers hard to believe given just how many fibre links I know of (and how many my own company handles).
Still sad that BT Infinity has the lions share again, so much for equivalence.
