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.

2. Call NS&I
If you prefer to pick up the phone, you can call NS&I for free on 08085 007 007. But, they will only have you on record if you are registered for phone or online banking.

3. Write to NS&I
You can also write to NS&I to check for any unclaimed Premium Bonds prizes. If you choose this method, you should include the following details in your letter:

  • Current name
  • Current address
  • Premium Bonds holder number
  • All previous addresses where you might have registered bonds
  • Your signature

You can send your letter to: NS&I, Sunderland SR43 2SB. Any prizes you claim will be sent to your home address.

When asked what the best way to find unclaimed Premium Bonds is, a spokesperson for NS&I told MoneyWeek: “The quickest way is to download our prize checker app or use the Premium Bonds prize checker at nsandi.com prize checker.”

They added: “If you think you have some Premium Bonds but you're not totally sure, our Tracing Service can help you check for any lost accounts with NS&I.”
