Hi,When my daughter had her home assessment for PIP they didn't check any room but he doesn't claim for physical conditions but i'm fairly sure they don't ask to check rooms for anything.They will ask you questions based on the descriptors and how your conditions affect you. You should try to answer with as much detail as possible and try to avoid answering with just a yes or no. If you have someone that can be there during the assessment then this can often help but you'll have to answer all those questions yourself, unless they are your appointee. Hope it goes well for you, good luck.
Just asked questions about the layout of the bathroom put did not ask to see it.
