It's possible that the government might step in (like all the others), but I doubt it.Same here now, Channel 4 or I don't bother.
Looks like F1's following in the UK is pretty much dead after next year. Terrestrial TV are losing the coverage and the British GP is finishing. I can't see any other track in the country picking it up as they don't have the infrastructure. Britain will be the home of F1 without the interest. Sad times, but it's only sport I suppose.
Too busy spending their money on other crap we don't need!
