Rick, the bed room tax as I call it only applies to social housing ( I know you know this), and by not defining what constitutes a bedroom no can avoid the " well we use it for something other than that" reasoning.
The RP (HA) council, should know how many bedroom the home has it rents to the tenant? Independently there are other way to know how many bedrooms a rented home may have such as the national census etc.
The Housing Association , council or Registered Provider will not mislead anyone, our whole Social security system is based on trust and most people are honest and compliant.
Most people will take the reduction in benefit and have to make up that shortfall in rent ( when they find out that have to do so, meaning so people will not pay due to all ways having it paid automatically!) What happens to people in arrears? who will be hit by this reduction? and have to make this shortfall up too?
This Tory led policy is tough on the working poor and tough on the benefits of the working poor.
The austerity measures are going to bite 2013 and people will be hurting financially and in their well-being.
