Thanks to posts on TP I became aware that my MIL was eligible to claim exemption from Council Tax bills as she was in receipt of middle rate DLA and lived alone. Within 3 weeks we received the claim form from her Local Authority, her GP had signed the relevant section, her claim was approved and a refund backdated to the start date of her DLA payments. Just amazing I thought after the long drawn out saga of the DLA claim. This money will be really important in helping to fund the care package my MIL needs to keep her at home as long as possible and I would urge anyone who thinks their relative or loved one may be entitled to look into it. I simply emailed our local authority and they sent a standard single page application form. Receipt of middle or high rate DLA would entitle someone with dementia to exemption from Council Tax if they live alone, or a discount if they live with someone. The GP or medical professional has to confirm severe mental impairment on the claim form. I think similar rules apply for someone with dementia in receipt of AA but I am not 100% clear as my MIL is under 65.
