The Premium Bond prize winners have been announced for December, including two new lucky millionaires. Premium Bonds are a savings account offered by National Savings & Investments (NS&I), one of the largest savings institutions in the UK, backed by the Treasury.

The accounts don’t earn interest traditionally and consistently. Instead, each bond is entered into a monthly, randomly generated prize draw. Between £25 and £50,000 can be invested in the account overall, and prizes of up to £1million can be won every month. NS&I has released the full list of December’s high-value winners, with savers from Shropshire and York receiving the jackpot prizes.

The first winning bond number of the £1million prize is 591RD417238 to a bondholder based in Norwich. This winner purchased their winning Bond in August 2024 and holds £35,000 in Premium Bonds.

The second £1million jackpot winner is based in Cornwall. Their winning Bond number is 615WP633178, and it was purchased in February 2025. They hold a total of £20,000 in Premium Bonds.

The full list of high-value winners has been published on NS&I’s website. The prize fund rate for this month’s prize draw is 3.6%, and the odds of any £1 Bond number winning a prize are 22,000 to one.

How to check if you’ve won Premium Bonds prizes

Premium Bonds savers can check if they’ve won a prize through the NS&I website, the prize checker app, or by simply asking Alexa. You’ll be able to find out whether you’ve won via the app or website on December 2.

To check on the NS&I website, you’ll need your Premium Bonds holder’s number. For the prize checker app, you’ll need your NS&I number or holder’s number. You can also use these tools to check for any unclaimed prizes owed to you.

In November, there were 2,665,351 unclaimed prizes worth £110,129,225 waiting to be claimed by Bondholders. 

According to NS&I, the “best way” to avoid prizes going unclaimed is to have them paid directly into your bank account or automatically reinvested into Premium Bonds (up to the £50,000 holding limit). Prizes automatically reinvested are immediately eligible for the next draw.
