Kc expressions- do you include water? CHEM

I'm doing the 2010 f325 legacy paper and the first question is an equilibrium with water molecules. I have heard different things about whether you should include water in the kc expression. I know that you must not include water in Kstab expressions. In the mark scheme they have included water in the kc expression.

Is it the case that you always include water in your kc expressions? Some clarification would be brilliant. Many thanks in advance
