I find this a little misleading because as I stated in in my background information:- "people with dementia are only disregarded (not counted) for council tax if they have a medical certificate and are in receipt of certain benefits" As the DWP make very clear on their application form for Attendance Allowance (The qualifying benefit that applies to some 95% of people with dementia) entitlement and receipt of the benefit commences on the date of receipt of the application by the DWP.
