I don’t know enough about in work benefits to help I’m afraid. Usually I would have suggested that a welfare rights advisor from the CAB would be the right place to get help. But clearly, they’ve not been able to. Here’s the CAB benefits guidance webpage: Benefits - Citizens Advice they do at least have a benefits calculator which might help. Other than that, is there a welfare right advisor at your local Jobcentre? Or your local authority? Or as George suggested, the MS Society or MS-UK?
