The rules for Premium Bonds changed recently affecting all customers
Premium Bonds savers from Wales may want to check their numbers to see if they have won any big prizes. NS&I has announced the big prize winners for the August draw, including the two £1million winners.
You can win huge amounts in the monthly prize draw, with two £1million top amounts always on offer. Other large amounts you could get include prizes for £100,000, £50,000 or £10,000. Yet it’s worth noting that most people win nothing, and most of the prizes are for small amounts of less than £100. Nonetheless, there were some big wins for Wales this time round.
There was one prize for £100,000 won by a person from the ‘Mid And South West Wales’ region. Their winning Bond was number 648RE293717, which they purchased less than a year ago, in November 2025, when they bought £19,000 of Bonds. They held a total of £24,350 going into this month’s draw.
There were also many five-figure wins for Bond holders for the different regions of Wales, with a total of 36 prizes across the country. These are the top prizes and the winning Bond numbers:

Who won the £1million prizes in the Premium Bonds August draw?
The first £1million jackpot amount went to a saver from Hampshire And Isle Of Wight with winning Bond 491KF169443. They purchased their top-paying Bond back in March 2022, when they bought £40,000 of Bonds. They held £49,850 in total Bonds going into the August draw, just shy of the £50,000 holding limit.
Bagging the other top prize was a saver from Kent, with lucky Bond 664BF890888. They didn’t have long to wait until their Bond paid out big, as they purchased this winning Bond only six months ago, back in February 2026, when they bought £20,000 in Bonds. They held £21,000 in Bonds in total going into the August draw.
The way Premium Bonds work is that rather than your holdings growing in line with an interest rate, each £1 Bond goes into the monthly draw, with the same chance of being paired with a prize. The odds of winning for any £1 Bond currently sits at 22,000 to one, while the prize fund rate for the scheme is 3.8 per cent.
Changes to Premium Bonds
Both the odds of winning and the prize fund rate increased from the July draw – up from the previous 23,000 to one and 3.6 per cent respectively. This was the first time the prize fund rate moved upwards in almost three years.
Even with the better chances of a win, your odds are very low of winning a prize, even if you have the maximum £50,000 invested. Plus the vast majority of prizes each month are for small amounts such as £25 and £50. So if you have a relatively large amount of Bonds, you may be better off putting them in a conventional savings account and getting some guaranteed interest rate growth.
