Financial guru Martin Lewis has revealed his ultimate money-saving secret. The Money Saving Expert took to Twitter to share the scoop on a new bank offer, which he described as having "serious perks".

Martin said: "Santander's launched a new bank switch deal, with some serious perks... FREE £175 + 7% savings + 1% cashback on bills + cheap spending abroad + possible 2% cashback on all spending."

Martin added: "Remember the 1st rule of MoneySaving Club is forget loyalty - judge each product on its own merits. If you try and stick with one bank for everything, you'll definitely not have the best deals."

Backing up Martin's point, a user named IamNotLuke said: "This is very true, I really like my bank as a bank but I don't use any of their other services because they aren't the best. Rather go best in class for each product."

Follower Pablo_MFC asked: "Can you see anymore banks in the near future launching a switching offer?"

Martin replied: "Yes hope so though it's been a bit sparse recently".

Martin also reminded his followers of the second rule of MoneySaving Club, saying: "The 2nd rule of MoneySaving Club is don't talk about MoneySaving Club, which to be fair I've broken on more than one occasion." It isn’t the only bit of financial wisdom Martin has shared in recent days, as he also urged Brits to check their pension plans as many could end up leaving their retirement savings to their ex if they die.

The finance whizz also urged any workers paid under £60k a year to take a simple 10-minute check to see if they were missing any financial help available to them via Universal Credit. Martin Lewis ' experts flagged up the advice in their latest newsletter, stating: "Who's likely missing out? Households with lower incomes, up to roughly £35,000 a year, though if you've kids, high childcare costs and rent, it could be £60,000."
