If you've had Premium Bonds sitting untouched for a while, there's genuinely good news this month. NS&I has increased the prize-fund rate to 3.8%, up from 3.3%, for the July draw and beyond — the first rate increase in almost three years, reversing a run of cuts that had taken the rate down from 4.65% back in September 2023.

What actually changed

Alongside the rate rise, the odds of any individual £1 bond winning a prize shortened to 22,000 to 1, from 23,000 to 1. NS&I estimates roughly 322,000 extra prizes will be paid out in the July draw compared with May, with the total prize pot increasing by more than £60 million — including 12 additional £100,000 prizes, 24 more £50,000 prizes, and 49 extra £25,000 prizes.

How Premium Bonds actually work

Premium Bonds don't pay interest in the traditional sense. Instead, the "prize rate" represents the average return NS&I pays out across all bondholders each month, distributed as a prize draw rather than as guaranteed interest — meaning your actual return could be zero in a given year, or it could be a life-changing jackpot. The £1 million jackpot remains the headline prize, but the vast majority of prizes are £25 or £50.

Is 3.8% actually competitive?

The prize rate is an average — mathematically, a saver with typical luck should expect a return somewhere close to but often below 3.8%, because the distribution is skewed by a small number of huge prizes going to a tiny fraction of bondholders. By comparison, the best easy-access cash ISAs are currently paying up to 4.62%, and top fixed-rate ISAs pay as much as 4.70% — both guaranteed, unlike the lottery-style Premium Bonds payout. For most savers seeking predictable growth, a competitive cash ISA remains the stronger mathematical choice; Premium Bonds suit people who value the tax-free "lottery" appeal and complete capital security more than maximising expected return.

Where Premium Bonds do have an edge

Because winnings are entirely tax-free and don't use up any of your ISA allowance, Premium Bonds can be a useful extra tax-free savings shelter once you've maxed out your £20,000 ISA allowance for the year. They're also backed 100% by the UK Treasury with no upper protection limit, unlike the £85,000 Financial Services Compensation Scheme limit that applies to most bank and building society savings.

Checklist: deciding if Premium Bonds suit you

• Check your ISA allowance first — a guaranteed-rate ISA usually beats the average Premium Bonds return for most savers.
• Consider your holding size — smaller holdings (a few hundred pounds) are statistically unlikely to win anything meaningful in a given year; the maths only starts favouring you with larger balances.
• Use NS&I's prize checker app or website monthly — unclaimed prizes don't expire but are easy to forget about.
• Treat it as a savings-with-a-lottery-ticket product, not a substitute for a guaranteed-rate account if you need predictable growth.

How this compares internationally

The UK's Premium Bonds model — a government-backed prize-linked savings product — has few direct equivalents abroad. The US has no federal equivalent, though some state-level "prize-linked savings" credit union products exist on a much smaller scale. South Africa and several other Commonwealth countries have experimented with similar lottery-bond structures, but none operate at NS&I's scale of over 24 million UK bondholders. Most other developed economies rely purely on guaranteed-rate savings products rather than blending savings with a lottery mechanic.
