Are you able to claim income-based ESA as your wife is no longer working?
This is a test similar to income support. In brief, your needs (and those of your partner if you have one) are compared with your resources, such as your income and savings, and the income-related allowance worked out from this comparison.
You cannot get income-related ESA if your capital or savings (or you and your partner's capital or savings) is above an upper savings limit of £16,000.
Your benefit will also be affected if your capital or savings (or you and your partner's capital or savings) is above a lower savings limit of £6,000.
