Martin lewis’s ‘£5,000 rule’ for premium bonds – need to know
- Money-saving expert Martin Lewis has issued a stark warning to Premium Bonds holders about his crucial ‘£5,000 rule’.
- The ITV and BBC star says unless savers have at least £5,000 invested, they’re likely wasting their time due to poor odds of winning anything significant.
- Despite NS&I announcing improved prize rates rising to 4.35% from September 2026 and better odds of 21,000 to 1, Lewis remains sceptical for smaller investors.
- “With less, the odds are you will win little or nothing,” he warned, particularly advising grandparents against gifting Premium Bonds to children.
- “So if you’re thinking of putting £1,000 or less into premium bonds for a child, it’s worth noting that with average luck our premium bonds probability calculator shows they are likely to win nothing over a year.”
- Martin said that premium bonds are typically only worth buying if you have more than £5,000, to give you a chance of winning the prizes. He noted that premium bonds are “best for”: Those with larger savings, say over £5,000, as then you’ve a better chance of earning closer to the published prize fund rate. “With less, the odds are you will win little or nothing”, he said
- Lewis explained that for most people, especially those with smaller savings, traditional cash ISAs offering guaranteed 4.4% returns are far better value than Premium Bonds’ lottery-style system.
- For those seeking thrills, he suggested: “Put your money in top savings and then take a couple of quid out and put it in the National Lottery.”
- NSandI defended their product, saying Premium Bonds remain “one of the nation’s favourite savings products” with over £403 million in recent monthly prizes.
