Prize-Linked Savings, UK-Style

What Prize-Linked Savings Means

Prize-linked savings is a well-established idea in the UK: instead of paying a guaranteed interest rate, a savings product gives every saver a chance at a prize instead. NS&I's Premium Bonds are the best-known example — over 24 million people hold them, and every £1 bond is entered into a monthly prize draw rather than earning interest. The appeal is straightforward: with Premium Bonds your original stake is never at risk, but there's a chance of a return far larger than ordinary interest would ever pay. Academics sometimes call this pure model a "no-lose lottery": you're never risking money you've put aside, only the interest or return you might otherwise have earned on it. (The Twenty is a hybrid rather than a pure example — see below for exactly how it differs.)

A Brief History

Prize-linked savings isn't a new or untested idea — it has a long track record in the UK and internationally. Premium Bonds were launched in the UK in November 1956 by the then Chancellor, Harold Macmillan, as "an alternative way to save." The first prize draw ran in June 1957, decided by ERNIE (Electronic Random Number Indicator Equipment), originally built by codebreakers from Bletchley Park. The original top prize was £1,000; it grew to £1 million by 1994, and Premium Bonds remain one of the UK's most-held savings products nearly seven decades later.

• The model has also taken root elsewhere. In the US, Save to Win launched in 2009 across a group of Michigan credit unions and has since helped members save tens of millions of dollars collectively, with small monthly and quarterly prizes funded separately from members' own deposits.
• In the UK, credit unions have run their own prize-linked schemes for years — see PrizeSaver below — showing the model works at both a state-backed scale (Premium Bonds) and a small, member-owned scale (credit unions).

Other UK Examples

Premium Bonds aren't the only prize-linked model in the UK. PrizeSaver is a real example — a savings account run by a network of UK credit unions, supported by the Association of British Credit Unions (ABCUL). Every £1 in your account at month-end earns one entry into the following month's draw, with a £5,000 top prize and twenty £20 prizes each month. It began as a government-backed pilot in 2019 and now runs independently of government. The underlying mechanic is the same one NS&I uses: save first, then get entered into a prize draw instead of relying purely on a fixed rate.

How Prize-Linked Savings Are Protected

Protection varies by provider, and it's worth understanding the difference before assuming any two prize-linked products work the same way:

• Premium Bonds: NS&I is backed directly by HM Treasury, which guarantees 100% of what you hold — not capped at a compensation limit the way bank deposits are. This is a different, and in some ways stronger, form of protection than the FSCS.
• Credit union schemes like PrizeSaver: savings held with a UK credit union are typically protected by the Financial Services Compensation Scheme (FSCS) up to £85,000 per person, the same scheme that covers most UK banks and building societies.
• The Twenty: we're not a bank, and our banking and safeguarding arrangements are still being finalised ahead of public launch — see our Security and Regulation pages for our current, honest position on this rather than a claim we can't yet back up.

Where The Twenty Fits

The Twenty follows the same basic instinct — save money, keep a shot at a prize — but changes one core mechanic: instead of a random monthly number draw, qualification for the weekly prize pool is earned by passing a skill test. £20 a month is the minimum: £15 of that stays in your own personal Vault regardless of outcome, and £5 unlocks your weekly Skill Tests, helps cover the cost of running your Vault account and supports that week's prize pool. Anything you contribute above £20 goes 100% into your Vault. See our Journal for what The Twenty is in full.

Prize-Linked Savings vs a Standard Savings Account

• A standard savings account pays a fixed or variable interest rate on your balance, with no prize element — the return is smaller, but certain and unconditional.
• A prize-linked account — Premium Bonds, some credit union schemes, and The Twenty — replaces or supplements that guaranteed interest with a chance at a prize instead.
• The Twenty differs from a pure prize-linked model in one respect: the £5 monthly allocation (unlocking one Skill Test opportunity per weekly cycle and helping cover the cost of running your Vault account) supports that week's prize pool and isn't part of your withdrawable balance — only the £15 Vault portion behaves like a traditional savings balance.

Prize-Linked Savings vs Prize Competitions

The two terms get used loosely, but they describe different mechanics. A prize-linked savings product (Premium Bonds, PrizeSaver, the £15 Vault side of The Twenty) is fundamentally a savings account — your money remains yours, and the prize element sits on top of it. A prize competition is a separate activity where entrants compete — typically through skill, knowledge or judgement — for a prize, without necessarily involving an ongoing savings balance at all. The Twenty combines both: a genuine prize-linked Vault, plus a skill-based competition (the weekly Skill Test and Crack the Vault) layered on top, paid for by a separate £5 contribution, which also helps cover the cost of running your Vault account. See our Skill-Based Prize Competition UK page for how that second part works.

Advantages

• With Premium Bonds your whole stake is always there to withdraw, and with The Twenty your £15 Vault portion is too — not winning never touches your savings balance. (The £5 monthly allocation is different: it's spent on your weekly Skill Test access and the cost of running your Vault account whether or not you qualify or win.)
• It can make consistent saving feel more engaging than watching a low interest rate accrue, which is part of why the model has endured in the UK for decades.
• It suits people who find a small, real chance of a large prize more motivating than a guaranteed small return — without asking them to risk money they can't afford to lose.
• Because the underlying balance is preserved, prize-linked savings can work as a genuine on-ramp into saving for people who'd otherwise put off starting altogether.

Limitations

• You give up a guaranteed rate of return. For most savers, in most periods, no prize means no extra return that period — though the underlying balance for Premium Bonds and The Twenty's £15 Vault portion is never lost as a result. With The Twenty specifically, the £5 monthly allocation is also a genuine cost: it's spent on Skill Test access and the cost of running your Vault account, and isn't refunded if you don't qualify or win.
• Returns are inherently uneven — a small number of savers win meaningfully more than the "average" rate implies, and most win nothing in any given period, even though everyone's stake is preserved.
• Prize-linked products are only as good as the protection behind them — always check how a specific provider protects your money before committing to anything, including The Twenty's own current, pending regulatory position.

Who Prize-Linked Savings Suit

This model tends to suit people who want their money to stay genuinely safe while saving, but who find a fixed, low interest rate uninspiring as a reason to keep contributing regularly. It's less suited to anyone who needs a guaranteed, predictable return by a specific date — for that, a standard fixed-rate savings account or cash ISA is the more appropriate product. Prize-linked savings is a complement to a saving habit, not a replacement for financial planning.

Why This Matters

• You keep the large majority of your contribution as genuine personal savings, not a stake you can lose entirely.
• Qualification for the prize pool depends on your own performance on a skill test, not a randomly drawn number.
• Full mechanics are on our How It Works page, and a direct comparison is on our Premium Bonds comparison page.
• For how the skill qualification itself is designed, see our Skill-Based Prize Competition UK page.
• See our Journal for what £20 a month can achieve over time, and how the Vault itself works.

Common Questions

• Is prize-linked saving the same as gambling? A pure prize-linked savings product like Premium Bonds keeps your entire stake safe — only the interest you might have earned is exchanged for a chance at a prize. The Twenty is a hybrid rather than a pure example: your £15 Vault portion works like savings, but the £5 monthly allocation is spent on Skill Test access and the cost of running your Vault account, and isn't refunded whether or not you qualify or win. Whether any specific product counts as gambling depends on its precise structure and how the legal requirements are met, not on how it's labelled — see our Regulation page for our current position.
• Do I lose money if I never win? Not from your savings: your £15 monthly Vault contribution is always yours to withdraw, whether or not you ever qualify for or win a weekly prize. But the £5 monthly allocation is a genuine cost — it unlocks one Skill Test opportunity in each weekly cycle that month and helps cover the cost of running your Vault account, and it isn't refunded if you don't qualify or don't win. So over a year, at the £20 minimum, £60 goes on Skill Test access and account costs and £180 builds your Vault.
• Is The Twenty regulated the same way as Premium Bonds? No. Premium Bonds are issued directly by NS&I, a UK government-backed institution, protected by a full HM Treasury guarantee. The Twenty is a private fintech company — our own regulatory and safeguarding position is set out in full on our Regulation page and is still being finalised ahead of public launch.
• Are prizes from prize-linked savings taxed? Premium Bonds prizes are tax-free, by NS&I's own published terms. The Twenty's tax treatment will be confirmed and published as part of our final terms ahead of public launch — we won't state a position here until it's actually settled.
• What is the £5 a month actually for? Your £5 monthly allocation unlocks one Skill Test opportunity in each weekly cycle that month and helps cover the cost of running your Vault account, the secure, interest-earning account your £15 is designed to be held in. Many accounts charge members a fee for access to better interest rates, and the £5 plays a similar role here. It also supports the weekly prize pool. It isn't refunded whether or not you qualify or win, and the Vault's banking and safeguarding arrangement is still being finalised ahead of launch.
• Can I lose my original stake in these products? In the pure prize-linked savings examples on this page, no: Premium Bonds always return your original bond value in full if cashed in, and PrizeSaver deposits are protected savings, not a stake. The Twenty is different in one respect — your £15 Vault portion is designed to be withdrawable regardless of outcome, but the £5 monthly allocation is spent on Skill Test access and the cost of running your Vault account, and isn't returned. That's why we describe The Twenty as combining a savings element with a skill-based competition, not as a pure prize-linked savings account.
