About the only "successful" privatisation in the UK was of telecoms.
The main infrastructure company that operates country wide (OpenReach) are heavily regulated by how much they can charge for last mile termination. So that means there's a floor to how cheap services can be, but gives wiggle room for charging more in return for better customer service (e.g. Zen, AAISP). I pay £53 a month, with no yearly price increases, for 900/100 FTTP - which is still pretty pricey compared to other places in Europe, but from what I've seen of the likes of Comcast in the US, is pretty decent. No data caps either.
