A Friendly Guide to Understanding Premium Bonds
Premium Bonds are one of the UK’s most talked-about savings products — but are they actually worth it? Whether you’ve just started your personal finance journey or you’re considering moving your savings around, here’s a clear, no-nonsense guide to what Premium Bonds are, why people love them, what to watch out for, and how they compare to other options like Cash ISAs.
What Are Premium Bonds?
Premium Bonds are a savings product offered by NS&I (National Savings and Investments). Instead of paying interest like a regular savings account, each bond you own (priced at £1 each) gives you a chance to win tax-free cash prizes each month — ranging from £25 to £1 million. The more bonds you hold, the more chances you have to win.
Unlike the lottery, you never lose your initial investment. You can cash out your bonds at any time with no penalties. Think of it as a savings account with a prize draw twist.
Why People Love Premium Bonds
- Tax-Free Prizes: Any winnings are completely tax-free, which is especially helpful for higher-rate taxpayers.
- No Risk to Capital: Your money is always safe with NS&I, backed 100% by the UK government.
- Fun Factor: It adds a bit of excitement to saving. Some people genuinely enjoy checking for wins every month.
- Easy Access: You can cash in your bonds whenever you like without fees.
- Great for Gifting: Premium Bonds can be bought for children, making them a popular long-term gift from parents or grandparents.
The Downsides (and Some Alternatives)
Of course, Premium Bonds aren’t perfect:
- No Guaranteed Returns: You might earn nothing at all in a given year.
- Average Return is Around 3% (as of 2025): But that’s just an average. Some people earn less, some win big.
- Inflation Risk: If inflation is higher than 3%, your money loses value in real terms.
Alternatives Worth Considering:
- Cash ISAs: Offer guaranteed interest (currently around 3-4%) and also come with tax advantages.
- High-Interest Savings Accounts: Often give fixed or variable interest, which may outperform Premium Bonds for steady savers.
- Stocks & Shares ISAs: Higher risk, but better long-term growth potential.
What If You Never Win?
The prize rate is currently 3%, but not everyone gets that. In fact, many people with small holdings go months (or years) without winning anything. Unlike a fixed-rate account, there are no guarantees — so it’s best to think of Premium Bonds as a low-risk place to park your money, not as a source of income.
How Much Should You Start With?
You can start with as little as £25, but to really have a decent chance of regular wins, many people aim to hold at least £5,000 to £10,000 in bonds. The maximum you can hold is £50,000.
Expected Earnings
Examples Based on the 3% Prize Rate Note: These are averages. Real returns can vary widely!
- £1,000 in bonds: Average return £30/year (but very likely zero if you’re unlucky)
- £5,000 in bonds: Average return £150/year
- £10,000 in bonds: Average return £300/year
- £50,000 in bonds: Average return £1,500/year
But again, these are averages. You might win a few months in a row or nothing at all for a while.

The Bottom Line
Premium Bonds can be a smart, safe, and even fun way to save — especially if you’re a higher-rate taxpayer or want easy access to your cash. Just don’t count on them for consistent income. If you like the idea of winning and don’t mind the uncertainty, Premium Bonds might be a great part of your savings mix.
