Martin Lewis has issued a "check now" warning over an extra £48,000 in your bank account. The ITV The Martin Lewis Money Show star was back on the programme on Tuesday, from 8pm til 9pm, for a live episode where he explored pensions, wills and the Cost of Living crisis.

During the hour-long show, Mr Lewis warned that about 200,000 people are missing out on thousands of pounds because the wrong partner in their relationship gets National Insurance credits. He said: "You build up National Insurance years which gives you how much of the full state pension you get in the end.

"Those who are not working or earning less than £123 a week are due National Insurance credits for childcare. However for many people in that circumstance, it is their partner who is working who does the childcare claim, not them. But the working partner already gets National Insurance Credits because they're working. So you want a non-working partner to be getting the credits, and they therefore need to be the one who is getting the benefit."

Martin continued: "Absolutely crucial. Check who gets the child benefit, if you're not working it should be in your name if you can." He said: "Eight years, each one of those years boosts your pension by £800 a year. So that's a boost on the final state pension of £2,400 a year.

"If you live for 20 more years, that's £48,000 extra state pension. This is not a trivial thing that I'm talking about. 48 grand eh?" He said: "Go to and check your National Insurance record to see if you have any missing years. And then check your state pension forecast to see if you're on track to get the full state pension.

"If you're not entitled to free years in other allocations, you are able to buy back years and for a payment of £800 it could be worth up to £5,000 over your state pension life."
