I have been living with my mother for last four years as her carer. And I declared I was living there. I gave up my business and lived off my savings for last two years only taking carers benefit the last year. I was in the understanding that as a living in carer I would be on my mothers discount. My mum has since moved into care recently. I got billed for three years council tax full amount no discounts. They say they just received the Doctors certificate that my mum was diagnosed with Dementia three years ago and since she exempt I have to stump up three years of full amount council tax? No discounts they said I could gret the single persons discount but only for last 6 months. I haven't worked last couple of years lived off my savings and cared for my mum. During of which I had two breakdown episodes and have suffered from depression throughout the caring. Is there anything I can do? Its a lot of money to find And I lost my buisiness caring for my mum.
