Francis ArnoldNS&I has announced it will cut the Premium Bonds prize fund rate from 3.60% to 3.30% effective from the April 2026 prize draw — the latest in a series of reductions since August 2025. At the same time, the odds of winning any prize will lengthen from 1 in 22,000 to 1 in 23,000. For the UK's approximately 23 million Premium Bonds holders, this raises a direct question: is it still worth keeping your money here when the best easy-access savings accounts now offer 4.5% or more?
What NS&I has announced — and why it matters
The April 2026 prize fund rate cut is the fourth reduction in less than a year. The trajectory tells a clear story:
- August 2025: 4.00%
- October 2025: 3.80%
- January 2026: 3.60%
- April 2026: 3.30%
Each cut has been justified by NS&I as reflecting "changes in the wider savings market," which is code for the Bank of England's base rate trajectory. According to NS&I's corporate communications site, the prize fund for April will be approximately £375 million — down from around £408 million in March.
The practical impact is meaningful. A saver with £10,000 held in Premium Bonds will receive, on average, £330 per year in prizes after the April change — down from £360. More significantly, the odds of winning any prize at all will be lower, with fewer large prizes available: the number of £100,000 prizes drops from 78 to 71, and £50,000 prizes from 154 to 143.
Premium Bonds vs. savings accounts: doing the maths
The core question is whether the tax-free nature of Premium Bonds compensates for their lower expected return compared to conventional savings accounts. The answer depends on your personal tax situation.
For a basic rate (20%) taxpayer, the government's Personal Savings Allowance permits £1,000 of interest tax-free each year. Below this threshold, a cash ISA or easy-access savings account offering 4.5% outperforms Premium Bonds for most savers — expected return of 3.30% vs. 4.5% gross (equivalent to 4.5% net below the PSA threshold).
For a higher rate (40%) taxpayer, the PSA drops to £500, and the tax-free prize income from Premium Bonds becomes more valuable. The effective gross equivalent of a 3.30% tax-free return for a 40% taxpayer is approximately 5.50% — comfortably beating most savings accounts on an after-tax basis.
For additional rate (45%) taxpayers, who receive no PSA at all, Premium Bonds can be genuinely attractive even at 3.30%, particularly once you've maximised your ISA allowance (£20,000 per year).
What a financial adviser would look at first
If you're uncertain whether to keep money in Premium Bonds after the April rate cut, a qualified financial adviser would typically examine three factors before making a recommendation.
Your full savings picture. Have you used your ISA allowance? If not, a Cash ISA at 4.5% or a Stocks and Shares ISA for longer-term money may offer better value than Premium Bonds, even accounting for the tax-free prize income.
Your time horizon. Premium Bonds are fully liquid — you can withdraw your money at any time. But if you don't need immediate access, a fixed-rate bond locking in 4.8% for two years may be a better choice. The trade-off is flexibility.
Your risk tolerance. The "return" on Premium Bonds is not guaranteed — it's probabilistic. Statistically, most savers receive close to the average rate, but there's variance. Some months you win more; some months nothing at all. If certainty of return matters to you, a savings account with a guaranteed rate is preferable.
The psychology of Premium Bonds — and why people stay
One reason millions of UK savers continue to hold Premium Bonds despite declining rates is the lottery element: the possibility, however small, of winning £1 million or £100,000 in a single draw. NS&I reported in February 2026 that there are currently two unclaimed £1 million prizes from previous draws, reminding savers that the top prizes do get paid.
This psychological appeal is real and not irrational. Behavioural economists call it "skewness preference" — the tendency for people to overweight the probability of large positive outcomes. For savers who view the prize draw as entertainment value added to their savings, the rate comparison with ordinary savings accounts may be less relevant.
That said, financial advisers generally recommend making savings decisions based on expected return rather than lottery appeal, particularly if the goal is wealth building over time.
Practical steps if you're reviewing your savings now
With the April rate cut confirmed, here are the steps worth taking before the end of March 2026:
Check your current balance. NS&I's online portal shows you exactly how much you hold and your prize history. Many savers discover they hold less than the £50,000 maximum allowed.
Compare against your ISA. If you have unused ISA allowance this tax year (which ends 5 April 2026), depositing into a Cash ISA before the tax year end locks in a competitive, tax-free rate for the year ahead.
Review your PSA situation. Your bank's interest statement will show how much savings interest you've received this tax year. If you're approaching the £1,000 basic rate threshold, the tax-free Premium Bonds become more attractive.
Consider splitting your savings. There's no rule that requires an all-or-nothing decision. Many savers keep a portion in Premium Bonds for the prize draw and hold the rest in a higher-rate savings account.
Speak to a financial adviser. The rules around savings, ISAs, inheritance tax and pension planning interact in ways that are specific to each person's situation. For savings decisions above £10,000-£20,000, independent advice from a qualified financial planner is usually money well spent.
According to the Financial Conduct Authority (fca.org.uk), savers should ensure any financial adviser they consult is registered on the FCA register and authorised to give investment and savings advice.
The April 2026 Premium Bonds rate cut is not a crisis — but it is a prompt. If you haven't reviewed your savings strategy recently, now is an excellent time to do so.
