To not let the housing officer in?

[tinatt]

My gran lives in a multi storey flat through the council.
She's 97 and has vascular dementia.
She hears and sees things and doesn't know who we are sometimes.
I have 3rd party permission to speak on her behalf.
Now she's just rang saying she wants to come and speak to us about the fire policy in the building.
If she comes in my Nanas flat,it will really set my nana off.
Last time the gas engineer came in she was screaming really bad,pulling her hair and crying as she thought he was going to take her in a nursing home :-(
It's pointless me trying to explain that it's just the housing lady as she doesn't know morning from night.
I was going to pop in the office and ask if she could talk to me about it (as I have 3rd party ) or pop to my house.
It would be pointless her talking to nan anyway as ..1 she wouldn't understand and 2.she would forget 2 seconds later.
This housing lady is so snooty and last time asked for doctors proof that she had dementia

Yes, talk to housing officer. Ring her and explain. It may be that there's a reason she needs to see inside flat.

LHA officer may be asking for doctor's proof that mum has dementia for their records, for all sorts of reasons . Including tenancy discussion purposes. If nan can't agree to /sign tenancy changes, if she no longer has capacity, do think about getting financial affairs & property Deputyship from court of protection.

LHA officer may be trying to help her or you. Did you know that if Nan has dementia 'significantly affecting her day to day living' (the wording is more archaic than that) and GP signs to say that, you can apply for exemption for her from Council tax? You get form from local borough council council tax office and need to ask GP to sign it.

All it was I think was because of her dementia she wanted to possibly fit something on the door where emergency services could tap the code in to get a key to open the door.
Il see what she says anyway and try and explain.

OP, your Nana doesn't sound safe to be on her own.

3rd party? Do you mean Power of Attorney?

How does your gran cope with you going in and out if she doesn't know anyone? How does she manage to keep safe when you are not there?

"3rd party permission to speak on her behalf"

You need to be clearer about what this enables from a legal, safety POV.

Is it Lasting Power of Attorney?
Is it just Personal welfare LPA?
Something else?

You need to provide a clearer summary of how you're legally able to speak on her behalf, and be ready to provide copies of the legal documentation explaining it (i'd pro-actively provide these to avoid having to show it to different people).

They need to ensure that you really do have the right to speak on her behalf, it's just part of their checks - you should feel reassured if they question it, it means they're looking out to ensure a vulnerable adult isn't being exploited...

Not every day is the same thankfully.
Some days she knows us and other days she doesn't.
Normally after we've been in a while and put her music on she calms down.

I completed a third party form with the council /HA when my her dementia was getting worse.
She signed it to say I had permission
