People who do not qualify for Carer's Allowance can still boost State Pension payments in retirement

dailyrecord.co.uk:

Carer’s Allowance is a benefit delivered by the Department for Work and Pensions (DWP) to people across the UK who are looking after a friend or family member for at least 35 hours each week.

Eligible claimants receive a weekly payment of £69.70, but if you live in Scotland, you will also receive Carer’s Allowance Supplement, an additional payment of £245.70 which is made twice each year - the next one is due in December.

The Scottish Government is working towards delivering a new benefit that will replace Carer’s Allowance by the end of next year, with a full national rollout planned for spring 2024.

Scottish Carer's Assistance promises to provide an ‘improved service’, designed with carers to meet their needs, and in line with Scottish Government principles of fairness, dignity and respect.
