RF, Remote control are a great idea and essential for In The Ear though it gives you something extra to lose
The NHS does not do ITE as far as I know with one exception and that is people with an ear issue that prevents then wearing a BTE. As for remote, I have no ide if they do that.
Now with mine, with 10 positive volume increments and 4 programs, I am really happy with them In fact a 5th program came in useful in a shop today with very loud and annoying music. Pull the batteries and it was 100% successful in stopping the noise.
