Hello, I'm Martin Lewis, and this is the cunningly named the Martin Lewis podcast.

I do wonder what that's going to be about.

Now, usually much of it comes from my BBC Radio 5 live show with Nihal Arthur Nica,

but don't worry, there's bonus money-saving tips and extra content

just for you lucky, lucky podcast listeners.

And today's pod is a special one. It's dedicated to a single subject,

probably the single most lucrative thing I have ever talked about. If your age under 73,

you may be able to pay £800 or far less, or possibly even get it free, to gain £5,500 or more,

and you can do it multiple times. But the clock is ticking. This is all about buying extra

national insurance years. I know it sounds dry and you have to give it a bit of effort, but it is

crucially important. Everybody aged under 73 has a listen in case you're going to be missing out

on tens of thousands of pounds. And the reason for doing it now is that finally, many can do it online.

Don't worry though.

There's also a teller's on if you've ever dipped into your children's savings

to prop up the household finances.

And don't worry, Nahal still gets put through his mastermind paces.

This time it's all about exactly when you're entitled to compensation

if your flight is delayed.

Play the theme tune, podcast producer Simon.

I got bills. I got to pay.

So I'm going to work for it.

I got a mouth.
