Part of the Series: Bonds & Fixed Income Products
Premium Bonds are a distinctive savings option provided by the UK government through National Savings and Investments (NS&I). Unlike conventional savings accounts or fixed-income products, Premium Bonds don’t offer a set interest rate. Instead, they provide savers with the opportunity to win tax-free prizes through monthly prize draws. For many, they represent a secure and exciting way to save, thanks to government backing and the potential for high-value rewards.
In this comprehensive guide, we’ll explore what Premium Bonds are, how to invest in them, their benefits, and address common questions to help you decide whether they’re right for your financial goals.
KEY TAKEAWAYS
What Are Premium Bonds
Premium Bonds allow individuals to save money while participating in regular prize draws backed by the government. Each £1 invested purchases one bond, and every bond has an equal shot at winning. The minimum purchase is £25, and the maximum investment per person is £50,000.
Premium Bonds do not guarantee a return. While your capital is safe, if you don’t win prizes, your real return could be below inflation, leading to a gradual loss in purchasing power.
Rather than earning a guaranteed return, your potential gains depend on winning in the monthly draw, with tax-free prizes ranging from £25 to £1 million.
The prize fund comes from the interest NS&I earns on government gilts. Owning more bonds increases your chances of winning.
How to Invest in Premium Bonds
Investing in Premium Bonds is simple and accessible. Here’s how to get started:
1. Eligibility
- You must be at least 16 years old to purchase bonds.
- You must be a UK resident or have UK residency status.
2. Decide How Much to Invest

4. Initial Investment
- Your bonds are assigned a unique bond number, which enters you into the monthly prize draw.

As a financial writer with over a decade covering UK savings products, I’ve spoken to many individuals who use Premium Bonds not as a core savings tool but as a fun, secure complement to their broader financial strategy.
Benefits of Premium Bonds
1. Government-Backed Security
All investments are 100% guaranteed by HM Treasury, offering unparalleled safety.
2. Tax-Free Prizes
All prizes whether small or as large as £1 million are exempt from income and capital gains taxes.
3. Excitement and Potential Upside
While there’s no guaranteed return, the thrill of winning up to £1 million adds an element of excitement that traditional savings accounts lack.
4. Full Liquidity
You can cash in your bonds at any time with no penalties, making them an ideal short-term savings option.
5. Capital Protection
You are always entitled to reclaim your full initial investment. There’s no risk to your original capital, unlike with stocks or funds.
6. Easy to Manage
NS&I offers a user-friendly online platform where you can monitor your bonds, check prize results, and redeem your savings.
If you’re not winning regularly, consider whether the effective prize rate (currently ~4.40% as of 2025) is working in your favor. With £50,000 invested, you’d statistically win around 2–3 prizes a year on average but real returns vary greatly.
How Do Premium Bonds Work?
Premium Bonds operate differently from standard savings accounts or investment vehicles.
1. Monthly Prize Draws
Each £1 bond is entered into a random monthly draw conducted by ERNIE (Electronic Random Number Indicator Equipment). Prizes span from £25 up to £1 million.
- As of 2025, the odds of any individual bond winning in a given month are approximately 1 in 24,000.
- More bonds = higher chances.
2. Where the Prizes Come From
NS&I invests the money from Premium Bonds into UK government bonds (gilts) and uses the interest earned to fund the prize pot distributed monthly.
3. Receiving Prizes
If you win, NS&I will inform you directly, and winnings will be paid either into your NS&I account or your nominated bank account.
NS&I reports that over 22 million people hold Premium Bonds making it the UK’s most popular savings product.
Pros and Cons of Premium Bonds
| Pros | Cons |
|---|---|
| ✔ Backed by the UK government for full capital security. | ✘ No guaranteed return some investors may never win. |
| ✔ All prizes are tax-free. | ✘ Most prizes are small (£25 or £50). |
| ✔ Each month offers a chance to win a £1 million prize. | ✘ Although the odds of hitting the jackpot are quite slim. |
| ✔ Easy access to your money no lock-in period. | ✘ No interest is earned like with savings accounts. |
In 2023, a 63-year-old from Surrey won the £1 million jackpot with just £1,000 in Premium Bonds, showing that even small holdings can lead to big wins.
Conclusion
Premium Bonds offer a safe and flexible alternative to traditional savings, particularly for risk-averse individuals who still want a chance to earn a return. Although you won’t earn steady interest, many savers are attracted by the possibility of winning tax-free prizes with the added assurance of government protection.
They’re not for everyone, especially if your primary goal is predictable income. However, for those seeking capital protection with an element of excitement, Premium Bonds can play a strategic role in a diversified savings plan.
Don’t treat Premium Bonds as a replacement for a long-term retirement savings plan. They offer excitement and capital security, but without consistent growth, they’re best used as a supplement not a primary pension solution.
To start investing, visit the official NS&I website and consider how Premium Bonds might align with your broader financial goals.
