As a current Sky TV customer who is thinking of leaving Sky altogether, their CS agents have been ringing me regularly to offer me their fibre broadband, obviously hoping to tie me in to their TV again. If I had accepted their first offer of broadband, I would actually be using it now, before it is offered openly to everyone.
However after asking around, there are a few reasons I didn't take Sky up on their offer. One is that I would had to move my telephone line rental to them as well, and I have heard that if I wish to take my line rental back to BT at a future date, this takes quite a while and I could even lose my current telephone number and maybe have some downtime too. Also, their fibre broadband is only just coming out of the test stage so I have no idea how reliable it will be. Plus I felt that because they are really pushing the "unlimited, no traffic shaping" aspect, there is a likelihood that the service will get over run with torrent users in the future and suffer a slowdown. That's only a guess, I have no proof of that of course. The other reason was that Sky apparently insist you use their router which I would not want to do - although I suspect there are ways and means round this.
BT Infinity sounded good and I was tempted as it is an unlimited package. I did hear that there is a lot of traffic management and that some people had had problems using Spotify on their service. But I understand that there a lot of happy users on Infinity. Another option from BT is their Business Infinity which promised priority connection at peak times and that sounded useful but was quite a lot more expensive. An unlimited option is available for an extra £5 a month.
Finally I settled on Plusnet and so far am very happy with their service. 120GB allowance (although I am hoping they will increase this at some time) excellent and reliable connection, and I pay an extra £5 a month for their prioritised connection too at peak times. Helpful staff, and I can use my own Airport Extreme router without breaking their terms and conditions. For the time being I have left my line rental with BT but plan on moving it to Plusnet soon.
Not sure if any of these ramblings are helpful to you, but good luck with your choice and I hope it all goes well for you. If it helps, 4 of my neighbours use the standard BT Infinity and one neighbour uses Business Infinity. All of them are happy with the service so far.
