Question Time: Overpay mortgage with savings? Can bank switching kill a credit score? How do I find my husband’s lost pensions?

In our Question Time podcast, Martin Lewis gives you answers on anything and everything, including: is it worth overpaying my mortgage, and when’s the perfect time to do so? I’m worried bank switching will kill my credit score, will it? I’ve got a Plan 2 and Plan 5 student loan; how do the repayments work? What’s the easiest way to track my husband’s lost pensions from various jobs? Plus, what’s the most unusual place Martin’s been asked a financial question? If you want to ask Martin a question, you now can! His Question Time podcast lets you ask Martin absolutely anything and everything (within reason!). So, if you’ve always wanted to know why he speaks so quickly, if he organises his wardrobe by colour or garment type, or have a very complicated question about your finances, email it to MartinLewisPodcast@bbc.co.uk.
