What happens if you're overdrawn when switching?

Martin Lewis takes you through the seven banks willing to pay you to switch, what it means for your credit score, joint bank accounts, overdrafts and how some make £1,000s doing it. Plus, you tell us if university was worth it. We discuss rumours that the Chancellor may cut the cash ISA limit, plus an update on car finance misselling. You can get in touch with the team by emailing martinlewispodcast@bbc.co.uk – make sure to send in your burning questions and any successes you’ve had following Martin’s advice
