Martin Lewis warns drivers of £1,000 problem if they passed driving test before 2014

In his never-ending and increasingly necessary quest to find ways for people to save money, Martin Lewis has been giving people advice on ways to save cash just by going through their wallets.

In his latest newsletter, he's found that many could benefit from checking the place their money actually lives.

His advice ranged from free money for some people who end up getting new debit card from their bank, to seeing if you could do with getting a railcard in there.

Another key piece of advice was to check if the condoms in your wallet were still within their expiry date, because when you're scrimping and saving every penny an accidental pregnancy is liable to throw quite the wrench into your financial plans.

However, his top tip for saving money just by going through your wallet was addressed to the 'one of two million whose photo driving licence has expired' as he warned them that a whole £1,000 could be on the line.

Bills are rising, inflation is at depressingly high levels and if you blink at the supermarket, the cost of pretty much everything suddenly goes up, so you probably don't want to wave goodbye to a whole grand if you can help it.

Lewis said that upwards of two million Brits may need to renew their driving licence as they run out every 10 years, meaning anyone who got their last one before 2014 risk getting caught and fined for driving with an expired licence.

While over two million drivers might be sitting with an expired licence, the DVLA told Lewis that this would also include those who were no longer behind the wheel.

The Money Saving Expert explained that it was a £14 (or £17 if you did it by post) fee to get a new driving licence and while that might be off-putting to some, the fine for not doing it could be as high as £1,000.

He urged Brits to make sure they knew when their licence expired and get on renewing it right away if it was becoming a problem.

The way to check whether your license is in date is to look at the '4b expiry label' in the corner.

During the cost of living crisis, Lewis has continued to come up with ways Brits could potentially save a bit of money.

Sometimes it's as simple as sending a couple of texts to check whether a financial storm was on the horizon.

He recently revealed that he almost didn't become the Money Saving Expert he is today because he himself was struggling to pay the bills and was told 'money doesn't work on television'.

Fortunately for lots of people, he managed to prove plenty wrong and establish himself as one of the UK's most popular and respected financial figures.
