NS&I has published the Premium Bonds winners for the September draw. The monthly draw always includes two jackpot prizes of £1million, along with a host of other big cash prizes. The September draw included five £100,000 wins for savers from the London area.
The five £100,000 wins were all won by people from the 'Outer London' area. One of these winners previously had just £1,000 in Bonds. Their winning Bond was number 111TQ746243, which they purchased in June 2006.
The other £100,000 prizes for the region were for winning Bonds number 433JT406941, 250DL128984, 27YR147372 and 249YS267583. There was also a haul of 11 prizes for £50,000 for the capital.
This included seven prizes for 'Outer London', one prize for 'London' and three prizes for 'Inner London'. One of the prizes for Outer London went to a person who previously had just £500 in Premium Bonds. Their winning Bond was number 263KJ376564.
Turning to the £1million prizes for September, the first jackpot win went to a saver from County Durham, with winning Bond number 224BZ748917. They bought their lucky Bond in June 2014, when they purchased £30,000 worth of Bonds. They held the maximum amount of £50,000 going into the September draw.
The second £1million jackpot was secured by a winner from Cumbria, with winning Bond 243VC581367. They acquired their winning bond in April 2015, when they invested in £9,480 in Bonds. They also held the maximum £50,000.
As NS&I announced the big prize winners, retail director Andrew Westhead said: "Congratulations to our two new jackpot winners from County Durham and Cumbria who've each won £1million in September's draw. Along with more than six million other prizes we're awarding this month, it's been another fantastic month for Premium Bonds holders."
The group director issued a reminder to savers: "We'd also like to remind all Bond holders to keep their contact details up-to-date with us to ensure they don't miss out on being notified of prizes." Each £1 Bond has an equal chance of being paired with a prize.
However, customers should be aware that the prize fund rate for Premium Bonds has decreased from the August draw, falling from 3.8 percent to the current 3.6 percent. The odds of any £1 Bond winning currently stand at 22,000 to one.
One long-term saver from Bedfordshire scooped a £10,000 prize in the September draw, for a Premium Bond they bought over 50 years ago, in January 1963. They previously held just £4 in Bonds.
At the other end of the spectrum, a saver from South Gloucestershire landed a £100,000 prize for a Bond they purchased just three months earlier, in June 2025. Another saver from Essex also bagged a £100,000 prize despite previously holding a mere £350 in Bonds.
The most effective way to boost your chances of winning is to buy more Bonds. Many people arrange their account so that if they win a prize, the winnings are automatically used to purchase more Bonds.
One advantage of setting up your account in this manner is that any Bonds acquired this way are eligible for the following month's draw. If you buy them yourself, you have to wait a full calendar month before they can be entered into the draw.
Another benefit of having the auto-reinvestment feature in place is that, if you've reached the maximum holding limit of £50,000 but then withdraw some of your holdings, any future winnings will be automatically reinvested again.
