Martin Lewis has issued a message to those over the age of 66.
The Money Saving Expert founder says that people who are of State Pension age could be claiming £278 extra each week - worth around £3,300 on average each year.
Writing in the latest edition of the MoneySavingExpert.com (MSE) newsletter, the financial journalist said it was a “national tragedy” that so many people of State Pension age, who have been paying National Insurance contributions for years, are missing out on a “critical boost to their income”, reported the Daily Record.
