This tool helps you check Premium Bond prize numbers against publicly available NS&I data. Results are for reference only and are not official confirmation.

Nothing on this site is financial or investment advice. Any returns comparison is a reference-only calculation, not a recommendation. Always verify any winnings with NS&I directly.

Acceptable use

Use the tool for your own personal checking. Do not attempt to disrupt, scrape at scale, or misuse the service.

No warranty & liability

We do not guarantee accuracy and are not responsible for any decisions made based on these results. The service is provided "as is".

Governing law

These terms are governed by the laws of England and Wales.

This site is independent and not affiliated with, endorsed by, or connected to NS&I (National Savings and Investments) or HM Treasury. We use publicly available prize data from NS&I.
