It is frustrating if claimants have to list their extra costs. My DSD33 lives with us. We pay the bills, we buy her shopping, we cook her food, we drive her to appointments etc, we pay for a cleaner because she can't clean.
I worry that the DWP will say that therefore she doesn't have extra costs because we pay. So once again it becomes a reason to reduce the benefits bill because an adult child lives with parents. She currently claims UC but if we charged her rent, she couldn't claim housing benefit because she lives with us, yet we need a bigger house because she lives with us.
If we kicked her out, she would incur much greater costs. She would need someone to help her have a cooked meal, someone to clean, she would have to pay rent. All of that would fall on the state. It is worrying enough that we don't know how she will manage once we have died, without adding that she might then have to work out her additional costs to claim PIP because it was denied when she was living with her parents.
And if you asked her what her additional costs are, she would probably say nothing. We have explained that once she has PIP she can use the money to get taxis - she gets lost a lot and this would help - but these reports only contribute to the benefits-bashing of disabled people.
