If I understand you correctly, her income is pensions of �41.19 p. wk. + widow's benefit of �73.20 p. wk. Is that right &, if not, what are the figures?
On those figures & the rent/council tax you state, I think she may be entitled to about �20 p wk Housing Benefit. This depends on various factors, including whether anyone else lives in the house with her. If you can answer the following I will see if I can be more specific:
1. Is her income as I have said, & if not what are the figures?
2. Does she live alone? If not, how many other people live in the house. Do they work? If not, what is their situation?
3. Is she aged 60 or over?
4. I don't understand why she came off Incapacity Benefit. Have you any more details about this? Is she still incapacitated?
5. You seem to think she would be better off if she stopped getting the pensions. Why do you think that?
6. Is her house rented from council or housing association, or is it a private rent?
