Be very very surprised Max, Plusnet have released their Full Fibre Service today, but it doesn't show up on the website yet unless you look at the detailed prices in the legal stuff. It can only be ordered over the phone.

Full Fibre 36 - £27, Full Fibre 74 - £30, Full Fibre 145 - £35, Full Fibre 300 - £40, Full Fibre 500 - £47, Full Fibre 900 - £55. Compatible line required.

On the forum JonoH says " for now it will be offered to customers calling in to renew contracts if FTTP is available to them."

Seems like a pretty low key product launch to me.
