After having issues with another company and Openreach (Openreach cancelled an engineer visit twice), a friend pointed out that Sky had LLU on my local exchange, and you don't need TV to get the broadband. I had a word with them through an online chat system in which they answered all my questions, so I figured I would give them a go. The online registration process was very simple and allows you to track the status of your order. The installation date they gave me was spot on, and they even texted me to let me know the line & broadband were active. Generally I've found their staff to be very helpful, and the speeds are well within the range they estimated. The best thing is the price - by far cheaper than the ISP I was going to use (£10 installation!), and the router comes free.
