Premium Bonds have been a British favourite for generations, with millions entering the monthly prize draws. The promise of tax-free prizes keeps many savers interested, but do they offer a sensible route for your money or are they mainly for those who enjoy a different kind of return?
There are plenty of stories, half-truths and misunderstandings circulating, which makes it harder to decide whether Premium Bonds are a good fit for your financial plans. Read on to separate fact from fiction and see how the actual returns compare with other savings options.
Before we dig into the numbers and the common misconceptions, here’s how the product operates and what you should expect from owning bonds.
How Do Premium Bonds Work?
Premium Bonds are a savings product run by NS&I and backed by the UK Government. Instead of paying interest in the usual way, they enter each bond into a monthly prize draw where bond numbers can win tax-free prizes from £25 up to £1 million.
Each £1 buys one bond; the minimum purchase is £25 and the maximum holding is £50,000. Bonds are entered automatically into the monthly draw, where winners are selected at random by a computerised system. The probability of any individual £1 bond winning a £25 prize in a given month was around 21,000 to 1 as of June 2024, so even the maximum holding does not guarantee a prize in any month.
Capital is safe because the product is government-backed, and prizes paid to UK residents are tax-free. The important trade-off is that returns come only from prizes, not from a fixed interest rate, so outcomes vary between savers depending on what they actually win.
Common Myths About Premium Bonds
Premium Bonds attract several persistent myths. Clearing them up helps you decide whether this form of saving matches your needs.
You’re Guaranteed to Make Money
Myth: Every bondholder will earn money simply by holding Premium Bonds.
Fact: Many people never win any prizes, even after years of holding the same bonds. With long odds on any individual bond, there is no guaranteed payout. Even when you hold a large number of bonds, your returns are uncertain and depend entirely on the random prize draws rather than a set rate of interest.
Only Big Investors Win Prizes
Myth: Only those with large amounts win the significant prizes.
Fact: Each £1 bond has the same chance of being drawn, so a small holding can still win a large prize. Larger holdings give more entries and therefore more opportunities, but no specific bond is favoured. That means luck plays a central role, and occasional big wins by smaller investors are possible even though they are not common.
Winnings Are Always Tax-Free
Myth: Premium Bond prizes are tax-free in all circumstances.
Fact: Prizes are tax-free for UK residents, but different tax rules may apply if you live abroad or change tax residency. It is sensible to check local tax rules if you are not resident in the UK, and to consider how any changes in your personal tax status might affect future prizes.
Premium Bonds Are Just Like Savings Accounts
Myth: Premium Bonds function like standard savings accounts.
Fact: Unlike interest-bearing accounts, Premium Bonds do not pay a steady return and do not guarantee growth. They trade predictability for the possibility of tax-free prizes. If you need a reliable income from your savings or a predictable rate of return, traditional savings accounts and other products are likely to be more appropriate.
With the mechanics clear and common misunderstandings addressed, the next question is how those prize-based returns stack up in practice.
What Are the Actual Returns on Premium Bonds?
Returns come exclusively from the monthly prize fund, not a stated interest rate. The annual prize fund rate was 4.00% in June 2024; this is an average that assumes prizes are distributed evenly across all bondholders, which is not how actual outcomes fall for individuals.
For example, a £1,000 holding has a statistical average that would equate to about £40 a year at the stated prize fund rate. In practice, many £1,000 holders will receive nothing in a given year, while others will collect several small prizes or occasionally a larger one. At the £50,000 maximum, the statistical average would be around £2,000 a year, but real returns can be considerably higher or lower depending on prize wins.
Because returns are outcome-dependent rather than guaranteed, Premium Bonds may produce a similar average return to some easy-access accounts over time, yet they offer no certainty for any given saver in any given year. This makes them less suitable for anyone who needs predictable income from savings; however, tax-free prizes can be an advantage for those who exceed their Personal Savings Allowance.
Next, we’ll put these figures beside more conventional savings products to give a fuller picture of trade-offs.
How Do Premium Bonds Compare to Other Savings Options?
Comparing Premium Bonds with other savings products highlights the fundamental differences: randomness of prizes versus guaranteed interest.
Below is a simple comparison that shows typical return types and practical differences.

Monthly prize draw (random)

Fixed term; penalties may apply for early access
With a typical easy-access or fixed-rate account, £1,000 at, say, 4.5% would produce a predictable return around £45 over a year (subject to tax where applicable). With Premium Bonds, the same £1,000 offers the possibility of prizes instead of steady interest; the average might be similar in the long run, but the timing and size of returns are unpredictable. The comparison makes the choice one between steady, known growth and variable, prize-based outcomes.
Understanding these differences helps frame who might find Premium Bonds attractive, and who should prefer more conventional accounts.
Who Should Consider Buying Premium Bonds?
Premium Bonds appeal to savers who are comfortable with variable outcomes and do not rely on their savings for regular income. They suit people who already have an emergency fund held elsewhere and are prepared for the possibility that their holding may not generate prizes for extended periods.
They can also interest those who benefit from tax-free prizes because they exceed their Personal Savings Allowance, or who value government-backed capital with immediate access. For higher-rate taxpayers, this tax treatment can sometimes make Premium Bonds relatively more appealing compared with taxable interest-bearing accounts.
However, Premium Bonds are not a good fit for anyone who needs predictable returns, depends on savings for day-to-day expenses, or has limited reserves. They should not be used as a substitute for essential income-generating savings. If you are unsure how Premium Bonds align with your overall plan, independent financial advice is advisable. This consideration naturally leads into the potential drawbacks to weigh before investing.
Risks and Drawbacks to Be Aware Of
The principal drawback is the possibility of no return: many holders see no prize income for long periods, leaving their nominal balance unchanged. Inflation is another key risk. If the price level rises faster than the average prize fund rate, the real purchasing power of money held in bonds falls unless the holder wins sufficiently above-average prizes.
There is also the matter of predictability. Without guaranteed interest, budgeting becomes harder for anyone relying on savings income. While capital is secure under government backing, the opportunity cost of not earning fixed interest elsewhere can be significant if prizes are infrequent.
Finally, although prizes are tax-free in the UK, different tax positions abroad, or personal financial changes, may alter the practical benefits. Weighing these risks against the potential rewards will clarify whether Premium Bonds play a useful role alongside other savings.
If you decide to cash out, the next section explains what to expect from the withdrawal process.
What Happens If You Choose to Cash Out?
Cashing out involves requesting the sale of some or all of your bonds and having the proceeds returned to your nominated bank account. Requests can be made online, by phone, or by post; processing typically takes around three to eight working days depending on the method and any security checks.
Bonds are removed from future draws once the withdrawal is registered. If a withdrawal happens after a monthly draw, any prizes already won for that cycle will still be paid. If you withdraw before the draw cut-off, those bonds will not be included in that month’s prizes. NS&I will notify you of any winnings separately, and any prize money owed will be paid even if your bonds have already been cashed out.
There are no penalties or withdrawal fees, and your original investment is returned in full apart from any unclaimed prizes you may be owed. With that practical detail covered, it’s useful to recap the chief benefits and drawbacks to help you decide.
Benefits
Premium Bonds offer government-backed security for capital, tax-free prizes for UK residents and immediate access without withdrawal penalties. For savers who prioritise capital protection and the possibility of occasional large, tax-free payouts, they provide an alternative to interest-bearing accounts.
Drawbacks
The main disadvantages are uncertainty and inflation risk: there is no guaranteed income, and funds held in bonds can lose purchasing power if prize returns don’t keep pace with rising prices. They are not suitable where stable, predictable growth is required, and they should not replace emergency savings or essential income-generating accounts.
Make an informed choice by balancing these benefits and drawbacks against your broader financial needs and priorities. If Premium Bonds seem appropriate, consider how they fit alongside other savings rather than as a sole solution.
