Premium Bonds are the UK’s most popular savings product — over 23 million people hold them. Offered by National Savings and Investments (NS&I) and backed by HM Treasury, Premium Bonds pay no interest. Instead, every £1 bond you hold is entered into a monthly prize draw for tax-free prizes ranging from £25 to £1,000,000.
Key takeaway: In 2026, the Premium Bond prize fund rate is 4.40% — meaning the total prizes paid out each month are equivalent to 4.40% annual interest on the total bonds outstanding. Your personal return depends entirely on luck. For higher-rate taxpayers and large savers, Premium Bonds can beat taxable savings accounts. For smaller balances, a top easy-access savings account may reliably outperform.

How the Prize Draw Works
Each £1 bond gets a unique number. Every month, ERNIE (NS&I’s random number generator) selects winning numbers from the pool of all eligible bonds. Bonds must be held for at least one full calendar month before entering their first draw.
Prize breakdown (2026 approximate distribution):
| Prize value | Approximate number per month |
|---|---|
| £1,000,000 (jackpot) | 2 |
| £100,000 | 4 |
| £50,000 | 8 |
| £25,000 | 16 |
| £10,000 | 38 |
| £5,000 | 74 |
| £1,000 | 1,600+ |
| £500 | 4,700+ |
| £100 | 20,000+ |
| £50 | 60,000+ |
| £25 (most common) | Millions |
The vast majority of prizes are £25. The jackpot prizes (£1 million) generate excitement but have an extremely low probability — roughly 1 in 24 billion per bond per draw.
Your Odds of Winning
| Bond holding | Expected annual prizes (at 4.40% rate) | Approximate probability of winning any prize in one month |
|---|---|---|
| £1,000 | ~£44/year expected | ~1 in 27 chance per month |
| £10,000 | ~£440/year expected | ~4 in 5 chance per month |
| £50,000 (maximum) | ~£2,200/year expected | Near-certain to win something each month |
Important caveat: “Expected” prizes are averages — in reality, outcomes vary. With £1,000, you might win £25 in January, nothing for three months, then £50 in May. The expected value calculation assumes perfect statistical distribution, which rarely holds for small bond holders over short periods.
Premium Bonds vs Easy-Access Savings Account
| Scenario | Premium Bonds | Easy-Access Savings Account |
|---|---|---|
| Rate comparison | 4.40% prize rate (expected, not guaranteed) | 4.5–5.0% AER guaranteed |
| Tax | Tax-free | Interest taxable above PSA |
| Capital security | 100% guaranteed | FSCS up to £85,000 |
| Access | 3–8 working days | Same day or next day |
| Best for… | Higher-rate taxpayers, £10,000+ holdings, prize excitement | Basic-rate taxpayers, certainty seekers, smaller balances |
Tax-Free Premium: When Premium Bonds Win
Example: Higher-Rate Taxpayer with £50,000
- Easy-access savings at 4.5%: £2,250 interest; £500 PSA used; £700 taxable at 40% = £280 tax owed; net = £1,970
- Premium Bonds at 4.40% expected: ~£2,200 in prizes; £0 tax; net = £2,200
Premium Bonds win here by ~£230 per year for this higher-rate taxpayer.
Example: Basic-Rate Taxpayer with £5,000
- Easy-access savings at 4.5%: £225 interest; within £1,000 PSA; £0 tax; net = £225
- Premium Bonds at 4.40% expected: ~£110 in expected prizes; but with only £5,000 in bonds, many months may return nothing
- Easy-access savings more reliably beats Premium Bonds at this balance for a basic-rate taxpayer
