What information is given to landlords?

Under the Data Protection Act and Social Security Acts we cannot automatically give information about Housing Benefit claims to landlords. 

However, if a tenant has given us written permission to talk about their claim, we will tell their landlord:

Whether there is a claim for Housing Benefit and, if so, whether we have made a decision about it;
Whether we need further information to make a decision on the claim and, if so, what information this is.
