Claiming HB/CTB do I have to tell my landlords

For the first time in my life I have just filled in the local authority HB/CTB claim form. In the middle it says if I don't want the LA to contact my landlord don't sign & date the section. Yet at the end of the form is a two side page called 'Rent Proof' form for my landlords to complete.

So does this mean the LA will expect to contact the LL. I really don't want this as the LL is a friend of several of my neighbours who I've got to know and my LL can't be relied upon to be very discreet.

Help please
