NS&I – National Savings and Investments – 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. In 1996, it became an Executive Agency of the Chancellor of the Exchequer.
More than a third of the UK's population has money in Premium Bonds. NS&I currently holds over 900,000 unclaimed Premium Bond prizes worth more than £44 million. The oldest unclaimed prize belongs to a man from South Yorkshire who won £25 in 1957. Two £100,000 prizes, a £50,000 prize and two worth £25,000 also remain unclaimed.
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.
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.
