What’s the best way to stooze (pervert 0% cards to make money)? | Top savings for 17yr-old | Will I lose Child Benefit?

In this special Question Time edition of The Martin Lewis Podcast, host Martin Lewis is temporarily replaced by podcast producer Simon, who steps in as the curator of listener questions. The episode covers a range of personal finance topics, starting with a deep dive into 'stoozing'—using 0% credit cards to generate interest on savings. Martin explains that using a 0% purchase card for regular spending is far more effective than money transfer cards due to high transfer fees, making the purchase route the clear winner for maximizing returns. The discussion then shifts to child benefit, where a caller earning just over £60,000 temporarily but below the threshold for the full year is advised to do nothing, as the system averages income over the tax year. A teenager seeking better savings rates is guided toward the Nationwide FlexOne Saver for children, which offers 5% interest. For an 18-year-old’s first international trip, Martin recommends a Chase debit card or Revolut prepayment card to avoid credit card risks, while suggesting the parent cover the required credit card deposit. The episode ends with a heartfelt birthday tribute to Martin, featuring a playful exchange with his wife Lara, who 'steals' his birthday, and a surprise badge for their daughter Sapphire. The tone is warm, humorous, and informative, blending financial advice with personal anecdotes.
