Martin Lewis has issued a warning about spending when you are away on holiday. He shared the important tip to remember during his BBC podcast.

On a question time edition of the podcast, a question came in from a mum whose 18-year-old son is going away on a lads' holiday. She asked what was the best spending card for him to take with him, or whether she should give him some cash.

She explained she wanted to avoid giving him a credit card as she wasn't confident he would be responsible with it. Yet the place where he was staying needed a £300 credit card deposit.

In response, Mr Lewis said his top pick for cards she could go for was Chase. He explained: "Technically you have to open a bank account to get it, but you don't need to switch bank account.

"The Chase bank account is available for anyone aged 18 or older. It's openable via an app. So effectively you can open this up, you put money in it that you want to spend and it gives you the same near-perfect rate that the bank gets when you spend, because it doesn't add a non-sterling exchange rate fee.

"So I think that's a really simple option. It's a debit card, it doesn't have an overdraft facility. It doesn't do a hard credit check, it just does an ID check and it doesn't affect his credit-worthiness."

Another card he suggested was the Revolut pre-payment card, where you load the card up with the amount you want to spend. Regarding the credit card deposit for the accommodation, Mr Lewis said this is a common stipulation, often being required for booking a hire car abroad as well.

He said if you need to pay a deposit on a credit card, it could be difficult to get one for an 18-year-old as they may not pass the credit check. Mr Lewis suggested that perhaps the mum could contact the company and pay the deposit on behalf of her son.

Mr Lewis added another word of caution for young holiday makers. He said: "One of the biggest dangers for finances and young people is drinking. The problem when we drink is we lose all our sense of control.

"So it's very difficult what you advise young people. Do you tell them take cash out so you've only got the amount you can spend on that day. That keeps you to a budget.

"But then it does wrong, they haven't got any money left and they can't get back to where they need to go, which can be dangerous.

"Or do you have a card that has an unlimited spending facility on it. It's quite a difficult one at that age. The best thing is to be sensible and not drink too much."
