'As for the 'What is a bedroom/bedroom size' issue, we have taken legal advice and the number of bedrooms in a property is as stated in the tenancy agreement.

Where in the Act does it allow for the opinion of a third party to dictate the amount of benefit that a person should receive?

Whether a room is, or is not a bedroom is a matter for the local authority to demonstrate and between them and the tenant.'

That is PRECISELY what I said BH. Nothing about '3rd parties dictating benefits'.

When a tenant rents a property from us, it clearly states in their tenancy agreement, which they must read and sign indicating that they accept the terms and conditions therein, 'Type of property: 3 - Bedroom Semi-detached house' or similar. this is the legal document defining the number of bedrooms in our properties.
