NS&I Unclaimed Premium Bond Prize Search

National Savings and Investments

NS&I is one of the largest savings organisations in the UK, with over 26 million customers and more than £100 billion invested. NS&I separated from the Post Office Savings Bank in 1969, becoming National Savings. In 1996, it became an Executive Agency of the Chancellor of the Exchequer.

NS&I currently holds over 680,000 unclaimed Premium Bond prizes worth more than £39 million. The oldest unclaimed prize belongs to a man from South Yorkshire who won £25 in 1957. A £100,000 prize won by a London woman in 2007 and a £50,000 prize won by a women in Kent in 2007 remain unclaimed, as well as four £25,000 prizes. Many prizes are owed heirs of deceased relatives and owners who received Premium Bonds long ago as a child, and have since forgotten of their existence.

After 18 months, prizes that haven’t been cashed in are classified as unclaimed; however there’s no time limit for claiming prizes and NS&I is backed by HM Treasury, and there is no overall limit on how much is guaranteed.
