National Savings and Investments (NS&I)

General information

Premium Bonds are one of the nation’s most popular investments, brought to you by NS&I. We pay out over two million tax-free cash prizes every month, creating random moments of happiness. And two very lucky winners scoop our £1 million jackpot every month! We are backed by HM Treasury, so all the money invested with us is 100% secure.

Every £1 you invest in Premium Bonds gives you a separate and equal chance of winning a cash prize in a monthly draw. Prizes range from £25 to our two £1 million jackpots and are free from UK Income Tax and Capital Gains Tax. Over 21 million people currently hold Premium Bonds. You can currently invest up to £50,000 – giving you even more chances to win.

The prize draw is powered by ERNIE, our legendary random number generating machine. His name stands for Electronic Random Number Indicator Equipment. Over the years he's become smaller and faster – he’s now in his fourth incarnation. He uses thermal noise generation to create random signals which are converted into winning Premium Bonds numbers for each monthly draw. His history of creating these randomly-selected moments of happiness has inspired #ERNIEmoments – our way of celebrating life's much-loved little surprises.
