A Premium Bonds Alternative, UK-Built

Why People Look For a Premium Bonds Alternative

Premium Bonds are hugely popular — over 24 million people hold them — but they're not for everyone. Some holders go years without winning anything above the smallest prize, since the odds are fixed and identical for everyone regardless of how long they've held their bonds. Others want their saving to feel more engaging than waiting on a monthly draw they have no influence over. If either of those describes you, it's worth understanding what a genuine alternative — not just another prize draw — actually looks like.

Premium Bonds

• Issued by NS&I (UK government-backed), launched in 1956 and still one of the UK's most-held savings products.
• Pay no interest — instead, every £1 bond is entered into a monthly prize draw.
• Winners are selected entirely at random by ERNIE (Electronic Random Number Indicator Equipment), NS&I's random number generator, at published odds of roughly 21,000 to 1 for each £1 bond in a given month's draw.
• £25 minimum purchase, £50,000 maximum holding per person; monthly prizes range from £25 up to the £1 million jackpot, funded by a variable annual prize rate.
• Your original bond value is always returned in full if you cash in — it's never at risk, and it's backed by a full HM Treasury guarantee rather than the standard FSCS compensation limit.

The Twenty

• A private UK fintech product, not a government scheme.
• £20 a month is the minimum — £15 of that builds your own personal Vault, which you can withdraw at any time.
• £5 unlocks your weekly Skill Tests, helps cover the cost of running your Vault account and supports that week's collective prize pool. Anything you contribute above £20 goes 100% into your Vault instead.
• Qualification for the weekly prize pool (Crack the Vault) is earned by passing a Skill Test — not by a randomly drawn number.

How Winning Actually Works

• Premium Bonds: every eligible bond has the same fixed, published monthly odds of winning, decided purely at random — nothing you do can improve your chances.
• The Twenty: qualification is earned weekly by passing a three-trial Skill Test (a combined score of 6 or higher out of 9). Every qualifying member then has a genuine shot at that week's Crack the Vault stage, decided by completion speed rather than a fixed random probability.

Understanding the Odds

"21,000 to 1" for Premium Bonds means each individual £1 bond has that fixed probability of winning something in a given month's draw — holding more bonds improves your overall chances proportionally, but no bond is ever more or less likely to win than any other, no matter how long you've held it or how you use the product. The Twenty doesn't publish a fixed numerical probability in the same way, because the mechanic is different in kind, not just in degree: qualification each week depends on passing the Skill Test on your own performance, not on a probability assigned to your account.

The Core Difference

Premium Bonds' prize draw is pure chance: every bond has an equal, fixed, published probability of winning each month, decided entirely at random. The Twenty's weekly prize pool is only open to members who've earned qualification through the Skill Test — performance decides who gets a shot, not a random draw. That's why we describe The Twenty as a modern-day Premium Bonds: save money, get a shot at a prize, but skill determines qualification instead of a random draw.

Which Is Right For You?

If you'd rather your odds be fixed and entirely independent of anything you do, Premium Bonds' pure-chance model is the more direct fit — and its HM Treasury backing is a genuinely strong, hard-to-match form of protection. If you'd rather your own performance play a genuine part in whether you get a shot at a prize each week, that's the gap The Twenty is built to fill. There are two differences: how qualification for the prize is decided, and what's at stake. With Premium Bonds your whole holding is preserved; with The Twenty, £15 of your £20 minimum builds your own withdrawable Vault, while the £5 monthly allocation is spent on Skill Test access and the cost of running your Vault account whether or not you win. See our Prize-Linked Savings UK page for the broader category, or our Skill-Based Prize Competition UK page for how the Skill Test itself is designed.

Common Questions

• Is The Twenty an official Premium Bonds alternative? No — Premium Bonds are a specific NS&I product. The Twenty is an independent, differently-structured product that shares the same broad idea (save money, keep a shot at a prize) with a different qualification mechanic.
• Are the two equally safe? Not in the same way. Premium Bonds carry a full HM Treasury guarantee. The Twenty is a private fintech company, and our own banking and safeguarding arrangements are still being finalised — see our Security page for our current, honest position.
• Can I hold both? Yes — nothing about The Twenty requires you to give up any other savings product. Many prize-linked savers hold more than one type of account.
• Why would I choose The Twenty over just buying more Premium Bonds? If you specifically want your own preparation and performance to influence your shot at a prize each week, rather than a fixed random probability, that's the core difference The Twenty is built around.
