Premium Bonds at a Glance
Premium Bonds, introduced by National Savings & Investments (NS&I) on behalf of the UK Government, are a government-backed savings product. Unlike conventional savings accounts that pay interest, Premium Bonds give holders the chance to win tax-free cash prizes, including prizes of up to £1 million. Launched on 1 November 1956, they have been held by millions of people across the UK for decades.
Each £1 Premium Bond number is entered into a monthly prize draw. While there is no guaranteed return, all money held in Premium Bonds is backed by HM Treasury, meaning the original amount invested does not fluctuate in value. The total prize fund is governed by an annual prize fund rate set by NS&I and reviewed periodically. Details of the current prize fund rate and odds are published by NS&I.
Premium Bonds can be purchased by individuals aged 16 or over. A parent, guardian or, in some cases, a grandparent can also purchase and manage Premium Bonds on behalf of a child under 16.

How Premium Bonds Work
Premium Bonds operate on a simple basis. Each £1 Bond number represents a single entry into a monthly prize draw. A minimum holding of £25 is required, and individuals can hold up to £50,000 in total. Holding more Bonds increases the number of entries into each draw, though it does not guarantee prizes.
Monthly Prize Draws and Winning Chances
Prize draws take place monthly, typically at the beginning of each month. The odds of any individual £1 Bond winning a prize, as well as the overall annual prize fund rate, are determined by NS&I and can change over time. NS&I publishes the latest odds and prize fund details on its website.
- Eligibility: Bonds must be held for a full calendar month before entering a draw. For example, Bonds purchased in January are first eligible for the March draw.
- Duration: Bonds remain eligible for draws until they are cashed in.
Prize Distribution Overview
Each month, NS&I awards millions of tax-free prizes worth hundreds of millions of pounds in total. The majority of prizes are smaller amounts, with fewer higher-value prizes awarded. Full details of prize numbers, values and winning locations are published in NS&I’s monthly results.
Understanding how prizes are distributed and how eligibility works can help set realistic expectations about how Premium Bonds operate.
Acquiring Premium Bonds
Premium Bonds can be purchased directly from NS&I through several channels. Bonds purchased for children are managed by a nominated adult until the child reaches the age of 16.
Purchasing Channels
- Online: Available at any time via NS&I’s website
- Telephone: Suitable for those who prefer to speak with NS&I directly
- Post: Paper application forms are available on request
Costs and Holding Limits
There are no fees or charges associated with buying, holding or cashing in Premium Bonds.
- Minimum purchase: £25
- Maximum holding: £50,000 per individual
- Fees: None
- Holding period: No fixed maturity date
Winning Odds and Prize Distribution
The annual prize fund rate set by NS&I determines the total value of prizes awarded each month. The odds of a £1 Bond winning a prize move in line with this rate and can change over time. Up-to-date information is published by NS&I.
Prize Tiers
Prize values currently range from £25 to £1 million and typically include:
- £25, £50, £100
- £500, £1,000
- £5,000, £10,000, £25,000
- £50,000, £100,000
- £1,000,000
Winners who have opted for paperless communication are usually notified by email. Prizes are paid directly into a nominated UK bank account or, if selected, automatically reinvested into additional Premium Bonds. Winners of the £1 million prizes are contacted personally by NS&I’s representative, commonly known as Agent Million.
Checking, Reinvesting and Cashing In Premium Bonds
Prize results can be checked using NS&I’s online Prize Checker or the Premium Bonds app. NS&I also publishes full monthly prize results on its website.
Reinvestment Options
Prize winnings can be automatically reinvested into Premium Bonds, provided total holdings do not exceed £50,000. Automatic reinvestment settings can be changed at any time.
Cashing In
Premium Bonds can be cashed in at any point. Withdrawal requests are typically processed within around three working days, although processing times may vary depending on banking arrangements and public holidays.
Safety and Security of Premium Bonds
Premium Bonds are backed in full by HM Treasury. This means that the capital held in Premium Bonds does not rise or fall in value and is guaranteed by the UK Government.
Government Guarantee
- Premium Bonds are backed by HM Treasury rather than the Financial Services Compensation Scheme (FSCS)
- There is no upper compensation limit; all eligible holdings are fully guaranteed
- Individuals can hold between £25 and £50,000, all backed by the Government
Comparison with Other Financial Products
Unlike shares or corporate bonds, Premium Bonds do not expose holders to market price movements or credit risk. They do not pay interest or dividends, and any potential returns come solely from prize draws funded by the prize fund rate set by NS&I.
Tax Implications and Inheritance
All Premium Bond prizes are free from UK Income Tax and Capital Gains Tax and do not need to be declared on a Self Assessment tax return.
In the event of death, Premium Bonds cannot be transferred to another individual. However, they remain eligible for prize draws for up to 12 months. Any prizes won during this period are paid to the estate.
Estate Administration
Executors or administrators should contact NS&I, who will request a death certificate and the appropriate probate documentation before releasing funds. Once processed, the Bonds can be cashed in and the proceeds distributed in line with the Will or intestacy rules.
Premium Bonds form part of the deceased’s estate for Inheritance Tax purposes, although any prizes remain tax-free.
Considering Premium Bonds
Premium Bonds are one option available for holding cash and operate differently from interest-bearing savings accounts. They do not provide guaranteed income, and outcomes vary between individuals. Understanding how they work, including prize odds and access arrangements, can help readers make informed comparisons with other savings products.
