Martin Lewis has urged people to take action with their state pensions before April 5.
The MoneySavingExpert founder said claimants must fill out gaps in their National Insurance contributions (NIC) or face losing thousands of pounds. Speaking on his podcast, Martin said anyone between the age of 45 and 70, who will receive the new state pension, can backdate any gaps to 2006.
But after April 5, claimants will only be able to fill in NIC gaps from the past six years. To get the new state pension, you must have contributed 35 years' worth of National Insurance.

Martin said: "On April 6, 2016, that was the day they introduced the new state pension. For those who hit pension age since then, you have been put on the new state pension.
"As part of that, transitional arrangements were put in place. Those transitional arrangements end this tax year, they end on April 5, 2023."
You can check your NIC's on the government's website. Martin added: "That will tell you when you are due to get your state pension and it will give you a forecast based on your current national insurance record of how much you are likely to get.”
"For those who are already at state pension age, go check your National Insurance record, which will tell you how many years of full contributions you have and whether, crucially, you have any gaps in your contribution record."
