Martin Lewis has shared some key tips when it comes to manage your bank account and household finances. He shared several pieces of advice about how to look after your everday expenses on his BBC podcast.

The consumer expert asked his fans to send in their thoughts about how to manage your daily finances if you are in a couple. Mr Lewis said behaviour has changed over the years, as people now tend to couple up at a later stage in life when they often have their own independent finances set up.

Mr Lewis said it's important to get this right and make sure you have the best strategy for you. He said: "The way that people operate their finances together is absolutely crucial."

One fan of the show said she has a joint account for her and her husband and that she sorts out all the finances, as she is "financially savvy" while her husband is not. Mr Lewis had a word of caution about this one-sided approach to handling your money.

He said you can illustrate the issue with "three Ds", namely death, divorce and dementia. Mr Lewis explained: "The problem with one person doing it is, if they are not communicating with the other partner, if there isn't a good financial factsheet list of details of who every provider is and why the decisions were taken and made, then if one of the three Ds were to hit the person who is in charge of the finances, it can leave the other partner in the lurch terribly."

Mr Lewis did a poll of his fans, with 50 percent of respondents saying that one person in their couple looks after the finances. The expert said he had met many people over the years who have suddenly faced this problem, particularly women in their 50s, where their husband had died.

Plea for couples managing their finances

In light of this danger, Mr Lewis issued a "plea" to the listener and anyone else where it is entirely one partner's job to look after the bills. He said: "It's fine for you to be the lead financer in your family, as long as your husband who you say isn't good with money, understands the decisions you're making and you have enough details and explanation, that in the event something were to happen to you, he would be able to take over relatively seamlessly.

"If not, the gift of looking after the family finances can be a curse." Another listener to the show said they and their partner have an informal meeting about every six months to go over their finances together.

Mr Lewis commended having a regular discussion like this. He said: "I think those meetings are incredibly important. Kitchen table financial budgeting meetings - especially if family finances are tight - are really worthwhile doing.

"So you've got somebody to pass the information off, and check that everybody is happy and everybody understands what is going on." Mr Lewis said there is no ironclad rule about how you do this.

He said: "There is no right or wrong way to do this, I wouldn't want to be prescriptive." Mr Lewis was particularly impressed with a tip from one person, who said they produce a 'monthly net worth statement' to get a snapshot of where their finances are at.

'Stand out' bank account for couples

One question came in from a person who was moving in with her partner. She wanted to know if there was a bank account Mr Lewis would recommend for them, ideally with some extra perks.

Mr Lewis said there is a "stand-out account" that may be worth a look here. He first referred her to the accounts where you can get some bonus cash for switching.

At present, you can get £200 from Lloyds Bank for switching to Club Lloyds or £500 for moving over to their Premier Account; as well as £175 from First Direct, £200 from Santander and £100 for moving over to Co-operative Bank.

Mr Lewis said his "top pick" from these providers for this listener would be the Santander Edge account, as you can get the £200 for your switch, as well as a 6 percent easy access savings account up to £4,000.

You can also get one percent cashback on bills paid by direct debit from your current account, with up to £10 a month in cashback on offer. This covers the £3 a month fee for the account and earns you £7 a month, or £84 a year. Mr Lewis said: "For joint accounts, if they are bill-only accounts, that would be your winner."
