NS&I saver with £700 scoops £100,000 prize with bond bought in 2006

This month’s Premium Bonds results show that major prizes aren’t just for those with the maximum £50,000 invested.

Savers with modest amounts have also landed life-changing wins, proving that luck can strike no matter how much is saved.

One London resident has shown this perfectly, winning £100,000 with total holdings of just £700. Their winning Bond, numbered 106JY501812 and worth £100, was purchased in February 2006.

After holding it for almost two decades, the result underlines the unpredictable nature of NS&I’s monthly prize draws.

Elsewhere, a saver in East Sussex also picked up a £100,000 prize despite holding only £1,706 in total. The successful Bond, numbered 498FZ384823 and worth £150, was bought far more recently, in April 2022, showing that life-changing sums do not always require years of waiting.

A winner in Plymouth enjoyed a similar windfall with what many would still consider a modest investment. They secured £100,000 with holdings of £2,000, thanks to Bond number 118ZD081905, worth £1,000, which dates back to October 2006.

Unlike traditional savings accounts, Premium Bonds do not accrue interest in a normal way, but NS&I customers instead being enrolled into a monthly cash lottery draw.

NS&I, the government-supported organisation managing the scheme, uses invested funds as loans to the state, making Premium Bonds a risk-free option for savers.

The prize rate, which is NS&I’s closest comparison to an interest rate, has stood at 3.60 per cent since August 2025 after reaching a high of 4.65 per cent in late 2023. In simple terms, this means that for every £100 invested, around £3.60 is paid out in prizes each year.

However, the rate is variable and can change depending on movements in the wider savings market or the Bank of England base rate. Crucially, it is only an average return, meaning many savers will receive far less.

What are the odds of winning?

According to NS&I, each individual bond has a one in 21,000 chance of winning in a given draw. But the probability of landing larger prizes is far slimmer.

Someone holding £1,000 in Premium Bonds could expect to wait roughly 3,500 years for a 50 per cent chance of winning £1,000. For a £50 prize, the same odds might take more than 200 years. A coin-flip chance of hitting the £1 million jackpot would require an estimated wait of around 3.2 million years.

Even savers who hold the maximum £50,000 face steep odds. Analysis by data scientist Andrew Zelin, carried out for the Family Building Society, suggests it would take about 60 years to stand an even chance of winning £1,000, and more than 64,000 years to have similar odds of securing the £1million prize.

Over the course of a single year, the chance of any individual winning the jackpot is around one in 49,563,028.

According to NS&I, each bond has an equal chance of winning a prize, however someone will have a higher chance of winning if they hold more bonds.

Tom Francis, the head of Digital Advice at Octopus Money, broke down the likelihood of the average Premium Bonds holder winning a big prize from NS&I’s lottery.

He shared: “Premium Bonds give you a chance to win big – but it’s a slim one, and you’ll likely be left waiting.

“Our research shows Premium Bond holders wait an average of 3.5 years before they win a penny, and the odds are skewed towards those with the biggest holdings: 94 per cent of jackpot winners held over £10,000.

“For the vast majority of everyday savers, they are failing to deliver returns while the money loses value to inflation.

“Even I’ve been tempted by the thrill of a prize draw, but if you have failed to win month after month, it might be time to think about where else you could put your money to make it work harder for you.

“Cash ISAs deliver reliable returns, while for many a Stocks and Share ISA can be a great first step into investing.”

At a national level, £40,810,000 was paid out to 2,875 winners in February. This included two jackpot prizes of £1 million, while 78 people collected £100,000. A further 154 winners took home £50,000, 311 secured £25,000 and 777 celebrated £10,000 prizes.

Valentijn Bakker, Editor of Nieuwe Casino, said: “The Premium Bond winners this month took a safer investment approach at a time when saving money is paramount and saw their patience rewarded.

“Premium Bonds are a low-stake, high-reward way of investing money that requires a bit of luck, but can provide plenty of excitement along the way. Not to mention high returns that will have offered much-needed financial relief to many this month.”

How to check if you have won

Premium Bonds draws take place every month, with prizes of up to £1million available. To see whether they have won, savers need their holder’s details before using the official prize checker. This requires a holder’s number, which can be found on bond records or within the app.
