Hi Please may i ask about council tax, my mom was diagnosed with Alzheimer's in January 2011, my dad looked after her until she had to go into a care home April last year. About 6-8 months ago i read about getting discounts on council tax once someone is diagnosed with Dementia and that you can claim back from previous years. My dad has claimed from when my mom was diagnosed and her doctor has sent the council a signed letter to confirm when she was diagnosed. The council have finally responded he is entitled to some back but only from 2014 when he started to receive attendance allowance. Is this correct that you can only claim it back if you have certain benefits? The reason my dad didnt claim for benefits before 2014 was because nobody informed him that he could, it was only when my mom went to day care a lady that worked there told him. There hasnt been anything ive read that says its benefit related. If anyone knows that would be lovely, thank you.
