More than 860,000 children in the United Kingdom currently hold Premium Bonds, with an average investment of approximately £3,261 in their accounts, according to recent data. Premium Bonds, a government-backed savings product offering tax-free prizes through monthly draws, remain a popular gift for younger relatives, given their combination of security and potential for financial reward.

National Savings & Investments (NS&I) recently analyzed prize distribution over the past decade, highlighting encouraging trends for junior savers. This year, a record number of under-16s are on track to win prizes, with 203,683 having already been successful. In 2025, 283,762 children won prizes compared to 156,343 a decade ago, showing a steady rise in youthful participation. Additionally, a record number of under-16s secured NS&I’s £100,000 second-largest prize in 2025, with 21 winners; so far in 2026, six children have claimed this amount. However, only five minors have won the £1 million jackpot in the past ten years.

The age distribution of child Premium Bond holders reveals 190,959 under fours, 272,502 between five and nine, and 401,194 from ten to fifteen. Average holdings vary, with under-ones investing about £1,643 and older children holding upwards of £3,000. While nearly 15% of child accounts have balances exceeding £1,000, a significant majority—around 87%—have under £1,000 invested. A small subset of accounts, numbering 22,314, hold between £40,000 and the maximum permitted £50,000.

Ownership rules require parents or guardians to open accounts on behalf of children, with documents and prize payments directed to the adult in control until the child turns 16. This system is designed to prevent adults from circumventing individual limits by funneling funds through children’s accounts. Despite this, legal ownership of the bonds and winnings remains with the child.

Premium Bonds offer a minimum purchase of £25 and a maximum holding of £50,000, making the odds of substantial winnings heavily dependent on investment size. On average, children who have won prizes held about £26,638, compared to £40,363 for adult winners. Recent data indicates that most jackpot winners had close to the maximum investment amount, with the lowest holding of a £1 million jackpot winner being £7,000.

While Premium Bonds provide a chance of winning tax-free cash prizes without risk to principal, financial advisors often caution that returns tend to be modest, especially for lower balances. Over five years, an average child might expect around £125 in winnings, which may not outpace alternative saving methods.

Experts recommend considering a diversified approach to childhood savings. Junior Individual Savings Accounts (Junior ISAs) provide a tax-efficient way to save or invest up to £9,000 annually. Cash Junior ISAs offer guaranteed interest rates, with some building societies currently paying between 3.8% and 4.15%. Stocks and shares Junior ISAs carry more risk but also the potential for higher returns over the long term, as demonstrated by examples of consistent growth in investment portfolios.

Another option, though less accessible in the near term, is opening a pension for a child, offering the benefit of compound growth and significant tax advantages, though funds cannot be accessed until retirement age.

In summary, while Premium Bonds remain a popular and secure gift option, they may be best used as part of a wider savings strategy that includes Junior ISAs and potentially other investment vehicles, depending on individual financial goals and risk tolerance.
