You can check if you have won using the Premium Bond prize checker.
Administered by National Savings & Investments (NS&I), Premium Bonds are much like savings accounts, but with one big difference: instead of a reliable interest rate your returns are determined by a monthly lottery.
While the bonds themselves don’t earn any interest, the annual prize pot, which is currently 1.25%, is used to fund the monthly prize draw. The gains on Premium Bonds are tax free.
The odds of each individual bond number winning any prize are 30,000 to 1.
