In June’s draw alone, there were almost six million tax-free Premium Bonds prizes distributed, worth over £376 million.
Jackpot winners are unlikely to miss the fact they have become millionaires since they are told in person by Agent Million, an anonymous NS&I employee that travels the country to inform jackpot winners of their newfound wealth.
However, it can be easy to miss if you win one of the smaller prizes, especially if you have not kept your personal information up to date with NS&I.
The good news is that unclaimed prizes do not expire, so even if you won a prize as far back as the 1950s, when Premium Bonds were launched, you can still contact NS&I and redeem the cash.
Your prizes do not expire even if you move abroad either, so it could be worth checking for unclaimed prizes or lost Premium Bonds.

A spokesperson for NS&I told MoneyWeek: “Premium Bonds prize winners receive notifications of their winnings if they have registered their contact details.
“However, sometimes customers relocate or forget to update their details with NS&I. This can lead to unclaimed prizes, especially for those who opt to receive their prizes via cheque rather than bank transfer.”
The spokesperson explained unclaimed prizes gradually accumulate every month and usually belong to Bond holders who "have not registered their details or have moved without telling us and their cheques are being returned".
They added: “We want to reunite people with their prizes, so this is a timely reminder that even for small holdings that may have been held for many years, it is worth registering your details with NS&I.”
How to check for unclaimed Premium Bonds
1. NS&I’s prize checker website and app
The quickest, easiest option for tracking down potential Premium Bonds winnings is to use the prize checker on the NS&I website or download the official prize checker app (available for Android and iOS).
If checking via the website, you will need your Premium Bonds holder number. If using the app, you will need your NS&I number, which is 11 digits.
Using either of these methods will show you your winnings from the last six draws and highlight any unclaimed prizes if you have them.
