What a big surprise! On the way home we dropped into Witley Court. I had heard about the fountain but the English Heritage handbook said it stops working for the winter at the start of October so we had missed it.
However when we got there they said it was a misprint and it was working every hour for about 20 minutes.
The house is very impressive, even though it is just a shell, but the fountain was spectacular, especially in the bright sunlight. Definitely worth a visit.
