My parents have also recently had FTTP installed (in fact I think it is in the same FTTP area as MartinS).
They've only gone for the 160/20 option, but for me the problem with this tech is distributing the max speeds it offers around the house. It's a fairly big house, and even using "ac" wireless (my own equipment + BT Home Hub 5 in exclusive 5GHz "ac" mode) I can only get ~90 megabits on the middle level and ~60 megabits on the top level.
Powerline networking has proved equally poor, with the latest "Homeplug AV2" compatible models only offering max 60 megabits of throughput to any other socket.
Not that my parents care much, but if it was my property I'd have to look for a professional contractor to install Ethernet all over the place. Since I'm stuck on an EO line myself with no prospect of increased speeds for years tweaking their crazy connection is as close as I'll get to having one.
