I think the local authority situation is really unfair and something that was over looked.
A friend of mine bought her house as an affordable housing within a local authority housing estate, in the new part of the estate which she lives her house is the only one that is privately owned and therefore she is the only one that is liable for the household tax.
And just to add insult to injury she is unemployed at the moment, paying a mortgage and the household charge where some of her neighbours are employed, paying low rent to the local authority and are exempt from the household charge, and her neighbours that are in the same position as her (unemployed) simply don't have to worry about it.
As much as I hate paying it I don't totally detest the charge but it needs to be looked at in a more equal manner.
