The Department for Work and Pensions (DWP) wants people to check if they are eligible for thousands of pounds in extra cash each year.
Taking to Twitter on Monday, the government department urged people to check their entitlement for Pension Credit. It added that those who are over State Pension age and on a low income could be missing out.
It comes after Age UK recently estimated that around a third (34%) of pensioners eligible to claim Pension Credit are still missing out on the cash.
