And to add to this...
Do not, do not, do not EVER fill out the form thinking that the money HAS to be used for whatever you put down on the form, or that you HAVE to implement the support which you say on the form is needed. The AA is for whatever you need it for.
When my MIL required AA some years ago, my husband filled all the forms in. MIL was then refused.
We applied again, only this time I went through the forms with him, asking what he'd put down as answers. He was very, very vague about what her situation was, because he kept falling into the trap of thinking the answer had to align with a care plan we were putting in place.
Example: question read along lines of "is the applicant able to sleep through the night alone". I put "no". He said "but we won't be able to pay for a carer to do that". And I with every single question I had to remind him over & over again that the question was asking what his mother could and could not do, and NOT "will you be paying someone to do this for her from the AA?". Rinse & repeat.
So, answer the questions accurately, based on their worst day, and don't ever stop to think about what you'll use the AA for, as it's disposal is not linked to your answers.
Another point - the AA is tax-free to the recipient, however, it is NOT tax free to whoever you give it to. That's not a problem if you are paying for goods in a shop, or a cleaner or gardener or carer who produces a receipt; tax is their problem. But as the government websites etc. say (or at least used to say) that AA can be given to a family member or neighbour etc. in exchange for their help, that person should really be declaring it to HMRC and needs to know so.
I am not saying this to be some sort of pedantic busy-body, I'm saying it because the department who issues AA had no understanding of the tax situation when I queried it back in the day when my MIL was awarded it. The last thing anyone wants is to inadvertently drop a 3rd party in the manure, but conversely, if you tell them about the potential tax implications, it's up to them what they do about it.
Final point - you are obliged to return the forms on time. We didn't, and when this happens you have to explain why. I explained that we were so busy looking after MIL that we didn't have the time to do the forms by the deadline.
For some reason, they wrote to us asking why the forms were late. I wrote back stating that as explained already, we were so busy looking after MIL that we didn't have the time to do the forms by the deadline. My MIL got the higher AA without a problem, and to this day I do not know if being asked to explain twice why the forms were late was because someone didn't read the explanation the first time, or if it was a test to try and trip us up. Just be consistent all the way, that's my advice.
