Advice on getting PIP f2f home visit

Hello, I am posting this on my partners behalf who is now needing support, his PIP assessment is in one weeks time. He's written:

I requested on the PIP application that we have a home visit, but it's been a standard letter I've received telling me to go to an assessment centre.

It says in the letter that they "may consider a consultation in your home but only where medical evidence confirms that you are unable to travel"

I have an undiagnosed joint condition that makes walking distances difficult, but I would be able to walk to the door of a building if I get a taxi there. However RosyApple needs pushing in a wheelchair much of the time out of the house due to ME/CFS and with my joint condition I can't push her about at the moment. I need her in the appointment with me as a backup and memory reminder for all the things that need discussing ( I have an issue with memory and cognitive function and am due to see an Neurologist in May, another of the reasons why I'm applying for PIP).

I have an initial physiotherapist appointment tomorrow to try and see what's going on with my joints, with the hips especially.

Do I stand any chance of being given a home visit? If so, what should I say to them to stand the greatest chance of being accepted for a home visit?

Thanks very much.

Thank you for that information there Gary,

I've been having a look through the information you've provided and referenced. It's not what I was hoping to hear.

I wonder if we need to discuss this with our GP as you say. If we attend this appointment I'm worried about the implications for both of us, and for my status as claiming PIP.
My partner has been my carer now for about 2 years, my ME/CFS has fluctuated around the moderate to severe end and so in order to leave the house (on the rare occasion I can) I usually need to be pushed in a wheelchair. Because of this I have the higher level of mobility.

My partner has not been able to do this now for some months because of his increasing pain, which has not been ideal. I can occasionally go short distances using a light weight tripod-seat-stick on my very best days but I can't know in advance when these will be.

My partner needs me there because of his neurological issues and there’s no one else who knows his difficulties as well as I do.

Now I can rest up for a few days and then push myself to go with him and use my stick (or even buy that rollater that I’ve been putting off buying for quite sometime), hope that my brain fog doesn’t affect me while I’m in the appointment with him, and potentially give myself days or more of symptom issues.
But our worry and question is… if I push myself to go with him is it putting myself at risk of losing my entitlement?
Am I at risk of being noticed (as they take your details when you book in), and having that marked against me when I next have an assessment, which will be in 6 months or so?
I can cope with the symptom flare but I don’t want to lose my only source of income as well.
