Carer 'disregarded' council tax reduction

All about money
I only recently read that a Carer can be 'disregarded' enabling them to apply for a Council Tax Reduction when they are living with, but not the Spouse or Partner of the person they are caring for?

Does this apply with all Councils?

Best regards.
Yes. Google "Council Tax Disregards" and look at the .gov site.
If the person you care for has dementia, then they too are disregarded on the grounds of severe mental impairment. Back dateable to the day of diagnosis!
My understanding of this is that you are not disregarded if you are a carer for a child under the age of 18. Does anyone know an6 different?

Thanks

Unfortunately that's true if it's your own child. Not sure if it's someone else's child though.
There is absolutely no logic to that exception, the rules are a mess.
What difference does it make who you are caring for, if you are a carer, you're a carer!
My son was brain damaged, I couldn't work as his needs were too great for any alternative care in our area (he worked his way through 14 carers!) so despite an honours degree, I had to stay home rather than work.
