Question Time: Is my energy bill wrong? Do credit cards repay 0% debt first? Is your AI investment a scam?

In our Question Time podcast, Martin Lewis gives you answers on anything and everything, including: why is my energy bill so high, and how do I check if it’s right? If I’ve got 0% debt and normal debt on a credit card, which do they clear first? I’ve just seen you advertising ‘Quantum AI’ with a guaranteed £25,000 return! Is it true? (Spoiler: no, it’s a scam). If you’ve earned cashback, but returned the product, what happens? Can you tell me the best account for under 11s? Plus, beam me up, Martin, what’s your favourite sci-fi? 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 if he’s got a favourite flower, if he’s a proper romantic, or have a very complicated question about your personal finances, email it to MartinLewisPodcast@bbc.co.uk.
