The Department for Work and Pensions (DWP) is warning that many people could be missing out on payments that will soon be worth up to £201 each week.
In a tweet on Friday, 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.
