[Perfect Choice]

Yes that is expensive as somebody has to pay for the fibre to your house so that is us!
At that price I can only see it being purchased by ultra enthusiasts and home workers whose business will fund the link or if you work for BT (which I do but not networking/BB) you can get BT BB/Infinity for virtually fee/discounted (one of the perks of the job).

It is interesting see how even with FTTC, how that final copper link to your house can still degrade the headline speed promoted by BT even for Infinity, so always worthwhile to use the address checker and see what they declare if interesting in Infinity.
