Not yet, what is crazy though is that it only effects council or housing association home tenants? So if you have lived in a council house for years and kids have left home you are doomed.
However if you have just moved in as a couple to a private landlord (who are normally 10% more expensive) have spare bedrooms and still claim Housing & Council Tax benefit it seems you are ok.
Crazy messed up idea with good intentions but not thought out.
2 different homes near me both have at least 1 disabled person in the couple, home adapted for the disabilities so they can stay in family home, both have grown up kids now left, both have 2 rooms that will be part of this bedroom tax. One of these has lived in the home for 37 years and it's a disgrace that now they may well be forced out.
