Premium bonds: more chance of win as NS&I ups prize fund rate again

Premium bond holders will have a better chance of winning prizes starting from September, following an increase in the prize fund rate by National Savings and Investments (NS&I). The change affects approximately 22 million individuals who hold the government-backed savings bonds. This marks the second adjustment in two months to the prize fund rate, according to recent announcements. The rate has been raised from 3.8% to 4.35% annually, effective with the September draw. Previously, the rate had been increased from 3.3% to 3.8% for the July draw. The updated rate means that the probability of winning with each £1 bond number has slightly improved, decreasing from 22,000-1 to 21,000-1. NS&I estimates that the September draw will feature 308,000 additional prizes compared to the current month's draw. The total prize pool is set to grow by roughly £63 million, reaching an estimated £497 million. The distribution of prizes has also shifted, with a notable increase in the number of higher-value awards. For instance, the number of £100,000 prizes is projected to rise from 83 to 95, and the number of £50,000 prizes will climb from 165 to 192. In contrast, the number of £25 prizes will decrease from nearly 2.3 million to approximately 1.7 million. One key advantage of premium bonds is their tax-free nature, making them especially attractive for higher-rate taxpayers. Holding the maximum allowable amount of £50,000 in premium bonds could yield a tax-free return of £2,175 based on the new prize fund rate. However, a major drawback is the lack of interest payments, leaving these bonds more exposed to inflation than traditional savings options. While the possibility of winning substantial sums exists, there is no assurance of any winnings at all. A freedom of information request conducted by AJ Bell revealed that 62% of all premium bond holders have never won a prize. This highlights the low likelihood of success for many investors. For those seeking a guaranteed return, alternative savings accounts offering up to 5% interest are currently available. Analysts suggest that premium bonds might appeal to savers who have exhausted their Individual Savings Account (Isa) allowances or anticipate exceeding their personal savings limits. Caitlyn Eastell, an analyst at Moneyfactscompare.co.uk, notes that while the improved odds may make premium bonds more appealing, they remain a game of chance. She cautions against interpreting the 4.35% rate as a guaranteed return, emphasizing that the cost of living continues to impact household finances. Sarah Coles from AJ Bell acknowledges the modest improvement in the prize fund rate and the reduced odds, but stresses that the average bondholder will still likely win nothing in an average month. Smaller holdings face even lower chances of receiving any form of return, as data shows that fewer than 1% of prizes awarded between February 2025 and January 2026 went to accounts with balances below £1,000. Experts predict that potential reductions in the cash Isa allowance, effective next spring, could lead to increased interest in premium bonds. As the financial landscape evolves, savers may seek alternatives that offer both flexibility and the allure of potential windfalls, even if the outcomes remain uncertain.
