Premium Bonds

Premium Bonds is a lottery bond scheme organised by the United Kingdom government since 1956. At present it is managed by the government's National Savings and Investments agency. The principle behind Premium Bonds is that rather than the stake being gambled, as in a usual lottery, it is the interest on the bonds that is distributed by a lottery. The bonds are entered in a monthly prize draw and the government promises to buy them back, on request, for their original price. The government pays interest into the bond fund (currently 4.35% per annum from which a monthly lottery distributes tax-free prizes to bondholders whose numbers are selected randomly. The machine that generates the numbers is called ERNIE, an acronym for "Electronic Random Number Indicator Equipment". Prizes range from £25 to £1,000,000 and (since September 2026) the odds of a £1 bond winning a prize in a given month are 21,000 to 1. Investors can buy bonds at any time but they must be held for a whole calendar month before they qualify for a prize. As an example, a bond purchased mid-May must then be held throughout June before being eligible for the draw in July (and onwards). Bonds purchased by reinvestment of prizes are immediately eligible for the following month's draw. Numbers are entered in the draw each month, with an equal chance of winning, until the bond is cashed. As of 2015, each person may own bonds up to £50,000. Since 1 February 2019, the minimum purchase amount for Premium Bonds has been £25. As of September 2026 there are over 137.12 billion eligible Premium Bonds, each having a value of £1.
