> Surely it's better to have x providers all claiming to have installed fibre broadband to your area rather than have to put up with just one provider claiming to have installed fibre broadband to your area?
There is only one provider of "fibre" (FTTC) broadband: BT. They wholesale it to everyone else.
So if you take "fibre broadband" from Talktalk or Sky, you are getting BT FTTC.
