NS&I hikes Premium Bonds prize fund rate to 3.8% – more winners expected from July
National Savings and Investments (NS&I) has announced a significant increase to the Premium Bonds prize fund rate, lifting it from 3.3% to 3.8% from July 2026. The move, which affects more than 22 million bondholders, also improves the odds of winning from 23,000 to 1 to 22,000 to 1.
The state-backed savings provider confirmed that the July draw will see an estimated 322,000 additional prizes compared to the May 2026 draw, with the total prize pot swelling by more than £60 million. Winners will benefit from 12 extra £100,000 prizes, 24 more £50,000 prizes, and 49 additional £25,000 prizes. Lower-tier prizes will also increase significantly, with around 2.8 million £25 prizes expected – half a million more than in May – and the number of £50 and £100 prizes rising by roughly 200,000 each to over 1.9 million.
Andrew Westhead, NS&I retail director, said: "Premium Bonds offer the monthly excitement of tax-free prizes with 100% security backed by HM Treasury, and the flexibility to withdraw at any time. So, I'm pleased that from July we can improve both the prize fund rate and the odds, meaning even more chances to win for our 22 million Premium Bonds holders."
The rate increase reverses a cut made in the April 2026 draw, when the prize fund rate dropped from 3.6% to 3.3%. The new 3.8% rate is higher than the previous peak of 4.65% seen in early 2024, but remains below the best-buy easy-access savings accounts currently available.
Rate rises across other NS&I accounts take effect immediately
Alongside the Premium Bonds changes, NS&I also increased variable interest rates on four other savings products effective from Thursday, May 14, 2026. The new rates are:
- Direct Saver: 3.45% gross/AER (up from 3.05%)
- Income Bonds: 3.40% gross / 3.45% AER (up from 3.01%)
- Direct ISA: 3.80% gross/AER (tax-free)
- Junior ISA: 3.70% gross/AER (tax-free)
Westhead added: "We regularly review our products to ensure they reflect current market conditions, and we’re pleased to be able to improve rates across five variable savings accounts today. This reflects changes in the wider savings market and helps ensure we meet our net financing target."
The rate adjustments come as the wider savings market shows signs of modest improvement after a period of relative stability, though many top-paying accounts still offer rates above 4%.
Why the odds matter – and what a 3.8% prize fund rate actually means
The prize fund rate is the closest Premium Bonds have to an interest rate, but it is not a guaranteed return. It represents the average annual payout across all bonds, but because prizes are randomly allocated, many holders will receive far less – or nothing at all – while a tiny fraction win life-changing sums.
With odds of 22,000 to 1, a holder with the maximum £50,000 in bonds can expect to win roughly one prize every two months on average, though the actual number of prizes can vary wildly. The top prizes remain two £1 million jackpots each month, alongside numerous £100,000, £50,000 and £10,000 awards.
For context, the best one-year fixed savings accounts currently offer around 4.16% on average, according to Moneyfacts. That means a saver with £10,000 in a top fixed account would earn £416 in guaranteed interest over a year, whereas a Premium Bonds holder with the same amount would have a much lower effective return because the prize fund rate is diluted by the random distribution of prizes.
Nevertheless, the tax-free nature of Premium Bonds prizes makes them attractive for higher-rate and additional-rate taxpayers who would otherwise pay tax on savings interest. Basic-rate taxpayers have a personal savings allowance of £1,000 per year, while higher-rate taxpayers have £500.
Check your details: experts warn of missing prizes
Following the rate changes, financial experts are urging Premium Bonds holders to review their account details to ensure they do not miss out on winnings. Tim Grimsditch, managing director at Unbiased, highlighted that out-of-date bank details or addresses are among the most common reasons prizes fail to arrive.
He advised holders to check how their winnings are paid out. Historically, many prizes were sent by cheque, which can take significantly longer than direct bank transfers. Changing the payout method to direct bank transfer can speed up receipt of any winnings. Alternatively, holders can opt for automatic reinvestment, where prizes are used to purchase more bonds, entering them into the following month's draw immediately.
Mr. Grimsditch said: "If you believe you have won a prize from this month's Premium Bonds draw but you have not yet received it, there are several straightforward checks to make before assuming something has gone wrong."
He added that if a confirmed prize cannot be traced, NS&I can investigate and resolve most issues quickly once details are verified.
Background: Premium Bonds popularity and recent turbulence
Premium Bonds have long been one of the UK's most popular savings products, with more than 22 million holders and total investments exceeding £130 billion. The scheme was launched in 1956 as a way to encourage saving while offering the thrill of a lottery-style draw.
However, the product has faced criticism in recent years. In the spring of 2024, NS&I cut the prize fund rate from 4.65% to 4.4%, then again to 4% in the summer, before the rate dropped to 3.6% and eventually 3.3% in April 2026. These cuts frustrated savers who had come to rely on the relatively generous rates of 2023 and early 2024, when the Bank of England base rate was at 5.25%.
The new 3.8% rate still falls short of the best savings accounts, but the improved odds and higher number of prizes may help restore some confidence among loyal holders.
Broader implications: NS&I balancing act between savers and Treasury needs
NS&I operates under a net financing target set by HM Treasury. When interest rates are high, the Treasury prefers NS&I to offer competitive rates to attract savers and fund government borrowing. But when rates fall, NS&I must balance the need to remain attractive against the cost to the public purse.
The current round of rate increases suggests the Treasury wants NS&I to remain competitive in the savings market, particularly as the Bank of England base rate sits at 4.25% and other banks are offering fixed rates above 4%.
For Premium Bonds specifically, the product's unique structure means NS&I can adjust the prize fund rate without directly impacting the Treasury's borrowing costs in the same way as interest-bearing accounts. However, the prize fund must remain sufficiently attractive to prevent mass withdrawals, which could destabilise NS&I's finances.
The rising number of prizes – and the improved odds – are likely to be welcomed by the millions of Britons who hold Premium Bonds as a low-risk, tax-free savings option with a dash of excitement.
What happens next: July draw and beyond
The first draw under the new rate will take place on July 1, 2026, with results typically published on the first business day of the month. Holders can check their results online via the NS&I website or using the Premium Bonds prize checker app.
For those considering increasing their holdings, the maximum investment is £50,000 per person. Bonds must be held for a full calendar month before they become eligible for the draw, so bonds purchased in June will first enter the July draw.
NS&I has not indicated whether further rate changes are likely later in 2026. However, given the volatility of the savings market and the ongoing cost-of-living pressures on households, savers should remain vigilant and compare rates regularly.
Industry experts recommend that savers with larger cash reserves consider splitting their money between Premium Bonds and high-interest savings accounts to balance potential returns with the chance of a tax-free win.
Final thought: A welcome boost, but not a silver bullet
For the 22 million Britons with money in Premium Bonds, the rate increase and improved odds are unequivocally good news. More prizes, larger prize pots, and a better chance of winning should make the monthly draws more exciting.
Yet the fundamental nature of Premium Bonds remains unchanged: they are not a replacement for a high-interest savings account. The prize fund rate of 3.8% is a theoretical average, and many holders will earn less. Savers who prioritise guaranteed returns should still look to the best-buy savings accounts, which continue to offer rates above 4%.
As always, the golden rule of personal finance applies: don't put all your eggs in one basket. A balanced approach – combining Premium Bonds for their tax-free potential with easy-access and fixed-rate accounts for guaranteed growth – remains the most sensible strategy for most savers.
