Lost bond numbers or decades-old certificates can make a win difficult to check. Prizes do not expire, but changed names, addresses or bank details can leave money unclaimed.
Premium Bonds prizes can be checked through NS&I’s official Prize Checker, app or online account. Older prizes may need tracing using a holder’s number, NS&I number or historic personal details.
Check prizes with the details you actually have
The best route depends on your records: a holder’s number checks draws, an NS&I number helps access an account, and old certificates or addresses support a trace.
| What you have | Best official route | What it can answer |
|---|
| Holder’s number | NS&I Prize Checker or app | Latest draw and eligible wins |
| NS&I number | NS&I online account | Account access and prize history |
| Old certificate or bond record | Contact NS&I for a trace | Old holding and unpaid prizes |
| Only old name and addresses | NS&I tracing request | Whether NS&I can locate a record |
Use a holder’s or NS&I number
A holder’s number is the quickest way to check the latest draw through the official NS&I Prize Checker or app. Use an NS&I number to access your wider account and prize history.
Keep old certificates and letters
An old certificate can show a bond number, purchase date or historic address. Even bonds bought in the 1950s, 1960s or 1970s may remain valid and can help NS&I locate a record.
Avoid paid prize-release offers
NS&I does not charge to check, trace or release a prize. End contact with anyone requesting a bank transfer, cryptocurrency, gift cards or remote access, and use official NS&I contact details instead.
The NS&I Prize Checker and app are usually the fastest ways to check Premium Bonds results when you have a Premium Bonds holder's number. If you prefer not to use a screen, NS&I has also offered an official Alexa route for checking results; confirm that the service is currently available through NS&I before sharing any details with a voice assistant. For account access problems, a lost number or a complex historic case, telephone contact may be more suitable.
A letter or official form can also support an NS&I tracing request where you only have old paperwork, previous addresses or partial information. Never give bond details to an unofficial caller or search site.
Choose results, prize history or a record trace
Latest results, prize history and tracing unclaimed prizes are separate tasks, so choose the service that matches your situation.
Check the latest draw first
Use the Prize Checker when you know your holder’s number and want to see whether eligible bonds won in the most recent monthly draw. Recently bought bonds must be held for a full calendar month before entering a draw.
A Premium Bonds prize is tax-free, but it is not guaranteed interest. The prize fund rate describes the overall prize pool, while your own return can range from £0 to a prize in a particular month.
Use history for earlier wins
Prize history is useful for earlier winnings linked to an accessible account, especially after a move or a change to payment instructions. Older paper-era records may still require a separate NS&I trace.
Fix a missing recent payment
If a result shows a prize but payment has not arrived, check your bank details, address and payment preference. Contact NS&I after the normal processing period rather than starting a new trace.
For each monthly draw, NS&I normally publishes Premium Bonds results on the second working day of the month, although the published schedule is the final authority around bank holidays. Check the NS&I Prize Checker first, then allow until the seventh working day for Premium Bonds prize payments to reach the selected bank account or reinvestment destination. If the prize appears but no payment is visible after that point, review your Premium Bonds bank details and payment preference before contacting NS&I.
This differs from a Premium Bonds prize history, which helps review recorded wins, and from a search for unclaimed Premium Bonds, where NS&I must first locate and verify an older holding.
Trace old bonds and unpaid prizes safely
Decades-old Premium Bonds can often be traced if NS&I can verify the holder or estate. Valid unclaimed prizes have no deadline, but entitlement must be confirmed.
Give NS&I a full historic picture
Give NS&I previous names, addresses, approximate purchase dates and any bond or certificate numbers. A partial number or old savings letter can be useful evidence for a historic holding.
From old paperwork to payment
1. Gather names and addresses→2. Ask NS&I to trace→3. Prove entitlement→4. Update payment details
Prepare documents after changes
Name, address and ownership changes can explain an unpaid prize. Keep copies of photo ID, current address evidence, former-name documents and historic addresses; estate claims may require a death certificate and grant of probate. Do not send originals unless NS&I asks.

A document folder can keep old certificates, address evidence and probate papers together while NS&I checks a historic holding. Use it to store copies, not to send original documents unless requested.
- Keeps decades-old bond papers separate from everyday household post
- Provides one place for name-change and address evidence
- Makes it easier to retain copies of documents sent to NS&I

Claim only after ownership is confirmed
Claiming is usually an ownership and payment-details process rather than a public online form. NS&I may need to verify entitlement before paying a prize or updating a record.
Before claiming old Premium Bonds prizes, make a copy-based checklist:
- the holder's or NS&I number if known
- any old Premium Bonds certificates, bond serial numbers and purchase letters
- current photo ID
- proof of the current address
- every previous name and address that may appear on historic Premium Bonds records
- and evidence of a name change, such as a marriage certificate or deed poll
If bank details have changed, have the new account details ready but provide them only through NS&I's approved process. Where paperwork is lost, give approximate purchase dates, the original branch or method of purchase if remembered, and details of any executor, death certificate or grant of probate for an estate claim.
Keep checks official and expectations realistic
Only NS&I can confirm a prize, trace a holding or arrange payment. Premium Bonds are backed by HM Treasury and prizes are tax-free, but they are not a guaranteed-return alternative to a Cash ISA or savings account.
This guidance is not the main answer if you are choosing where to place new savings for a guaranteed return. Compare Premium Bonds’ variable prize-based return, access needs and savings limits with Cash ISAs and other savings accounts. It also does not replace probate guidance where ownership is disputed after a holder’s death.
Questions & answers
Can I check Premium Bonds by name?
No, the official Prize Checker does not provide a public name-only search. Use a holder’s number or NS&I number, or ask NS&I to trace a record using historic names, addresses and proof of identity.
Can I claim Premium Bonds prizes from 50 years ago?
Yes, there is no time limit for claiming a valid Premium Bonds prize. Bonds from the 1950s, 1960s and 1970s can be traced if NS&I can verify ownership or estate entitlement.
How long should a prize payment take to arrive?
Check the monthly result first, then confirm your bank and address details. If a shown prize has not arrived after the normal NS&I processing period, contact NS&I because the issue may be outdated payment instructions.
Do I pay a fee to claim an unclaimed prize?
No, NS&I does not charge a fee to check, trace or claim Premium Bonds prizes. Stop any contact that asks for an upfront payment, cryptocurrency or remote access to a device.
Start with the strongest record you hold
Use a holder’s number for the latest draw, an NS&I number for account access, and old paperwork or historic details for a trace. If a recent win is missing, update payment details first; for old or inherited bonds, ask NS&I to verify the record and entitlement before making plans for the money.
