Previously , local councils allocate housing tenancies based on an
assessment of needs, and by using a points system and
a waiting list .They then give a new tenant a suitable home,
according to their needs at that time.
If many years later a tenants family has changed,
then its not their fault that their home is a different size.
They will already have spent many long years on a
waiting list,and may find it difficult to go back onto
any waiting / transfer lists.They may also find that
any nearby smaller / cheaper properties have already
been taken up.
The bedroom tax is a severe and regressive tax unleashed
on to unsuspecting council tenants, to cause them
hugh personal instability and financial harm.
