The income of the person you care for
If you claim Carer’s Allowance the amount of means-tested benefit paid to the person you look after can sometimes be reduced.
For example, a person living on their own (or treated as living alone), or a person who is one of a couple who live alone and both get a qualifying disability benefit, would get the severe disability premium. (It is called the severe disability addition when paid as part of Pension Credit).
The severe disability premium (or addition) can only be paid to someone if no-one gets Carer’s Allowance for looking after them, so once Carer’s Allowance is paid to their carer, the severe disability premium or addition can no longer be paid.
If a couple qualifies for the severe disability premium/addition, they will be getting a double rate. If someone starts to receive Carer's Allowance for caring for one of them, they will get a single rate of the premium/addition. If another person starts to receive Carer's Allowance for caring for the other member of the couple, they will lose the premium/addition altogether.
Please note that having underlying entitlement to Carer’s Allowance will not affect the benefits of the person you are looking after.
