NS&I Premium Bonds: Are They Worth It in 2026?

SYM

Premium Bonds, run by National Savings & Investments (NS&I), are held by over 24 million people in the UK. Instead of earning interest, your money is entered into a monthly prize draw with prizes from £25 to £1 million. The current prize fund rate is 4%. But unlike a savings account, there's no guarantee you'll win anything. So are they actually worth it?

How Premium Bonds Work

You buy bonds in £1 units, with a minimum purchase of £25 and a maximum holding of £50,000. Each £1 bond is entered into the monthly prize draw run by ERNIE (Electronic Random Number Indicator Equipment). Prizes range from £25 (most common) to £1 million (two winners per month). Your capital is 100% safe — backed by the UK government. You can cash in your bonds at any time with no penalty. The current prize fund rate is 4%, meaning the total prize money paid out equals 4% of all bonds held. But your individual return depends entirely on luck.

What Returns Can You Actually Expect?

With a 4% prize fund rate, the median return (what most people actually get) depends on how many bonds you hold. With £1,000 in bonds, you might win 1-2 prizes per year (£25-£50). That's a return of 2.5-5% — but it's wildly variable. You might win nothing. With £10,000, you're likely to win 8-12 prizes per year, giving a more consistent return closer to the 4% rate. With the maximum £50,000, you'll win fairly regularly and your average return should be close to 4%. The key point: Premium Bonds work best with larger holdings. With small amounts, the randomness dominates and you might get nothing.

Premium Bonds vs Savings Accounts

At a 4% prize fund rate, Premium Bonds compete with the best easy-access savings accounts (also around 4-5%). But there's a crucial difference: savings account interest is guaranteed. Premium Bond prizes are not. A savings account paying 4.5% on £10,000 gives you exactly £450 in a year. Premium Bonds with £10,000 might give you £300 or £600 — you just don't know. However, Premium Bond prizes are completely tax-free. Savings account interest counts towards your Personal Savings Allowance (£1,000 for basic-rate taxpayers, £500 for higher-rate). For people with large savings who've used their PSA, Premium Bonds offer a tax-free alternative.

Who Should Buy Premium Bonds?

Premium Bonds make most sense for:
  • •Higher-rate taxpayers: The tax-free prizes are worth more to you than to a basic-rate taxpayer whose PSA covers their savings interest.
  • •People with large savings (£30,000+): At higher holdings, your returns are more consistent and closer to the prize fund rate.
  • •People who enjoy the 'lottery' element: If the chance of winning £1 million makes saving more exciting, that motivation has real value.
  • •Risk-averse savers: Your capital is 100% government-backed. No risk at all.

Who Should Avoid Them

Premium Bonds are less suitable for:
  • •Small savers (under £5,000): With small holdings, you might win nothing for months. A guaranteed interest rate is better.
  • •Basic-rate taxpayers with savings under £20,000: Your Personal Savings Allowance likely covers all your interest, so the tax-free benefit of Premium Bonds doesn't apply.
  • •People who need predictable returns: If you're saving for a specific goal by a specific date, guaranteed interest is more reliable than random prizes.
  • •Long-term investors: Over decades, the stock market significantly outperforms Premium Bonds. If your timeline is 5+ years, a Stocks and Shares ISA is likely better.

How to Buy and Manage Premium Bonds

You can buy Premium Bonds online at nsandi.com, by phone, or by post. The minimum purchase is £25. You can check prizes online, by phone, or through the NS&I prize checker app. Prizes under £5,000 are paid directly into your bank account or reinvested in more bonds (you choose). Larger prizes are paid by warrant (cheque). Cashing in is simple — request a withdrawal online and the money arrives in your bank within a few working days.

FAQ

What are my odds of winning?+

The odds of each £1 bond winning a prize in any given month are approximately 1 in 21,000. With 1,000 bonds, you have roughly a 5% chance of winning at least one prize each month.

Can I hold Premium Bonds in an ISA?+

No. Premium Bonds are a separate product from ISAs. They don't count towards your ISA allowance and can't be held within an ISA wrapper.

Are unclaimed prizes really sitting out there?+

Yes. NS&I estimates there are over £850 million in unclaimed prizes. Check if you have any at nsandi.com using the prize checker. It's worth checking, especially if you bought bonds years ago and moved address.
