Risk of moving line-rental from BT to your ISP?
I’m looking to upgrade my BB. My current ISP is TalkTalk, whom I use for free evening and weekend calls as well, but not line-rental. Talk Talk (and indeed many other ISPs) have several fibre-optic packages which are theoretically faster than my current service, plus they are cheaper (if you factor-in my £15.45pm line-rental to BT). However all of the packages require me to move my line-rental from BT as part of the deal. But what are the risks of doing so?
I Google’d the issue and read loads of horror stories about people having to pay BT engineers £80+ per hour to repair damaged telephone-lines because the line-rental through their ISP doesn’t include a maintenance element, which is why the ISPs can offer line-rental cheaper than BT.
I could do with knowing the facts. I don't want Sky and my area doesn't have cable, so there are few other other options.

After 12months argument between aky and bt I moved totally to sky. Any future issues will then be dealt with by sky only. It was in the end bt's fault and after conversations with both CEO's they sortes it and pais compensation. I would doubt any phone provider would not have a 'maintenance' element. I would say keep it all with one supplier if possible for rhis reason and cost benefits
