How can we help?

We’re happy to answer any questions you may have.

Do I have any unclaimed prizes?

How to find out?

We contact everyone when they win a prize but sometimes the good news doesn’t arrive. This might be because you’ve moved and not told us, you’ve changed some of your other personal details, or our letter went astray.

Don’t worry though. We’ll hold on to your prize until you get in touch with us. And there’s no time limit for claims.

Log in to view your prize history, or use our prize checker to see whether you have any unclaimed prizes.

Or you can write to us asking for your prize history (remember to include your name, address and NS&I number or Premium Bonds holder’s number). We’ll send you a list of the prizes you’ve won.

How to claim

Then, if you find out that you have won a prize but not received it, if you are registered already for our online and phone service, you can simply call us and we’ll help you with your claim.

Call us

If you are not registered already, you can either register for our online and phone service or you will need to write to us and tell us that you have an unclaimed prize. By registering you can choose any future Premium Bonds prizes paid straight to your bank account.


If writing to us please mention the following details in your letter:

  • Holder's number.
  • Current name.
  • Any previous names.
  • Current address.
  • Any previous addresses where bonds may have been registered.
  • Signature.

Please send your letter to NS&I, Glasgow, G58 1SB.

Prizes will then be sent to your home address as a warrant. Unfortunately we can not send unclaimed prizes direct to your bank account.

If your details have changed since you won the prize, tell us your old and current details and sign your letter.

Keeping us up to date

It’s important to keep your details up to date so you can receive any prizes you win.
