Hi, We are in a similar position,my husband's benefit will cease in August.I am retired but he still has a few years to go.I was hoping you had some replies!! If I find anything out I'll let you know.
Vicar1, your wife can apply for jobseekers allowance if she's available for and looking for work. It will be means tested on household income and savings.
Donkeyhag, a similar situation may apply - you might be able to claim an increase on your pension for your husband depending on the type of pension you have.
