They aren't that great, sorry, but i found BT worse, and no catch, but you need to look at the small print, don't sign up for anything you don't want.
We are with them, line rental, broadband, calls, but found the broadband service goes down quite a bit, perhaps it depends on the area don't know.
When contract came to end, they did offer an incentive of half price on part of the package, calls after seven pm free and weekends. We have stayed because didn't like the faffing around of changing again
