I agree - I want written confirmation, booking reference or similar for a room reservation... along with the price and Ts&Cs - cancellation terms, for eg.
I see
Shelsley Walsh's website doesn't show many prices (or I didn't spot them) and the
date search facility is tucked away at the bottom left of the home page - which suggests the hotel isn't encouraging guests to find or use it. Then, the only room package that shows any availability via the hotel is the King + Morgan Car Hire. Perhaps because there are terms and conditions associated with hiring the Morgan (age, clean driving licence) which needs to be confirmed direct when booking.
It may be they only take bookings for other rooms via listing / booking engine sites (like booking .com) though one of the (99% excellent) TripAdvisor reviews mentions
Voyage Privé which is one of those sign up for 'exclusive' membership deals (yeah, right) sites. I cba to join but maybe someone here is already a member and can ferret out the current prices... and someone may already have done that upthread but I've missed it.
However they're filling their rooms, according to the TA reviews they seem to have a hotel that everyone who
stayed 
has enjoyed and rated highly.
