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. If you are permanently in a care home this lower limit is £10,000.
Partners of ESA claimants may be required to undergo a work-focused interview for partners, as a condition for the claimant to receive continuous entitlement to ESA.
