There were several big cash prizes for Wales in the latest draw. Savers have the chance of scooping considerable sums in the monthly draw, including £50,000, £100,000 or even a life-changing £1million jackpot.

The top prizes included three £100,000 prizes for Wales, with a six-figure win each for a person for Cardiff , a saver from Mid And South West Wales and a customer from the North Wales region. There were also seven prizes for £50,000 for Bond holders from Wales.

The first of the £1million prizes for June was claimed by a Bond holder from the Cheshire West and Chester region, with winning Bond 573GA618329. Their winning Bond was purchased in March 2024, as part of a £23,400 investment. They had a total holding of £33,800 heading into the June draw. The second £1million jackpot was won by a saver from Leeds, holding winning Bond 662EK268242. This lucky Bond was bought relatively recently, in February 2026, when the holder purchased £8,300 worth of Bonds. They had a total holding of £42,425. Every £1 Bond entered into the draw has an equal chance of winning, with the current odds standing at 23,000 to one — but this is about to change. From the July draw onwards, NS&I will be boosting both the prize fund rate and the odds of winning. The prize rate is set to rise from 3.3 per cent to 3.8 per cent, while the odds of winning will improve from 23,000 to one to 22,000 to one. While the odds of scooping a prize are slim, the most effective way to boost your chances is to purchase more Bonds, thereby increasing the number of entries you hold in each monthly draw. Even so, the overwhelming majority of prizes are for modest sums such as £25 or £50. Several winners in June defied the odds by landing significant prizes despite having relatively little invested. One holder from the City of Bristol area walked away with £10,000, having had just £10 in Bonds going into the draw. Their winning Bond was number 13KN157809, purchased nearly 50 years ago in November 1979. Two other winners with less than £100 in Bonds also took home substantial sums. A saver from Coventry with just £50 won a £25,000 prize, while another from Norfolk, also holding just £50, claimed a £5,000 prize. Both savers purchased their winning Bonds in the 1980s. By contrast, a number of savers Bonds purchased very recently also landed impressive wins. Several customers who bought a Premium Bond in April 2026 were rewarded with sizeable prizes. Among them was a holder from South Yorkshire who won £100,000 after purchasing £9,300 in Bonds in April 2026, with a total holding of £16,300. Another winner from Outer London also claimed £100,000 after buying £600 in Bonds in April 2026, holding £9,375 in total.
