I was in the same boat, end of contract, bill going up to a point that I wasn't comfortable with. I had been with them so long that I had a ntlworld email address but it counts for nothing.
I couldn't be bothered with the annual end of contract fan dance so I rang them to tell them I didn't like the new price and that I was leaving. Ok they said.
I kept the broadband but reduced it from 100mbs to 50 mbs. I bought my wife a Humax Freeveiw box with 500GB storage. I bought myself an Nvidia Shield. We have a Now Tv account for movies.
She is more than happy with digital tv, her recordings and Now Tv. I stream everything I'm watching and am more than happy. The problem will arise once sport restarts but I suspect you know the solution to that.
