NS&I products explained — Premium Bonds, Income Bonds, Direct Saver and where each fits

National Savings & Investments — NS&I — is the part of the UK government that takes deposits from the public. It funds public borrowing alongside conventional gilt issuance, and it’s notable for being the only place in UK savings where your money is 100% backed by the Treasury rather than the £85,000 FSCS limit that applies to bank deposits.

That guarantee is the main reason people use NS&I. The rates aren’t usually the best available, and the products are simpler than commercial alternatives — but for amounts above £85,000, NS&I is the cleanest way to keep cash genuinely risk-free.

This is the practical overview of the main products.

The Treasury guarantee

The FSCS protects up to £85,000 per person per banking licence. Above that, money held with a single licence is unprotected if the bank fails.

NS&I is different. It’s an executive agency of HM Treasury, and all NS&I products are backed by the government in full. The £85,000 limit doesn’t apply. If NS&I “fails”, it’s a sovereign default — which is what the gilt market would call a Treasury default.

For practical purposes, NS&I deposits are as safe as UK government debt. This is essentially the safest cash holding available to a UK retail saver.

The downside: because NS&I doesn’t compete on rate, its products are typically priced below the best commercial banks pay. You pay for the safety in rate.

Premium Bonds

The flagship NS&I product. Instead of paying interest, Premium Bonds enter you into a monthly prize draw. Each £1 of bonds is one entry.

• Maximum holding: £50,000.
• Minimum: £25.
• Prize fund rate: the average return across the prize fund (currently around 4% — adjusted in line with prevailing rates by NS&I).
• Prize structure: tiers from £25 up to two £1 million jackpots a month.
• Tax: prizes are completely tax-free, regardless of holding size or amount won.

The headline prize fund rate is a fiction in the sense that very few individual holders actually earn it. The distribution is skewed: most holders win nothing in most months, occasionally win £25 or £50, very rarely win larger prizes.

For a holder with the full £50,000 in Bonds, expected long-run returns are close to the headline rate — but with high variance. The smaller your holding, the more variable your actual returns and the more likely you are to underperform the headline.

Premium Bonds make sense for:

• Higher-rate or additional-rate taxpayers with cash above the PSA. A tax-free 4% return is comparable to a 6.7% taxable return for a higher-rate taxpayer.
• People who hold the full £50,000 and so capture closer to the headline rate.
• People who value the upside of larger prizes (psychological), accepting lower expected returns than a guaranteed-rate account.

They don’t make sense for:

• Anyone covered by the PSA on alternative accounts — the tax-free benefit disappears.
• Anyone with small holdings — variance will likely give you a poor experience.
• Anyone who needs predictable income. Returns are lumpy and unpredictable.

Direct Saver

NS&I’s plain easy-access savings account. Variable rate, no fixed term, withdraw any time.

• Maximum holding: £2,000,000.
• Minimum: £1.
• Interest: paid annually, taxable as income.
• Access: online and phone only.

The rate is typically below the best commercial easy-access rates by 0.3–0.7 percentage points. For people not affected by the FSCS limit, a commercial easy-access account at a better rate is usually preferable.

The use case for Direct Saver:

• Holding amounts above £85,000 that you want easily accessible. Spreading across multiple commercial banks is the alternative, but Direct Saver is simpler administratively.
• As a single account holding the household’s “serious cash reserve” alongside other accounts at commercial banks.

Income Bonds

Like Direct Saver but pays interest monthly to a separate account rather than annually.

• Maximum holding: £1,000,000.
• Minimum: £500.
• Interest: paid monthly to a nominated bank account, taxable as income.
• Access: variable rate, easy access.

The same FSCS-replacement use case as Direct Saver, but suited to people who want regular income flow from cash savings rather than accumulating interest. Retirees living partially off interest from substantial cash holdings are the typical user.

NS&I fixed-rate products (Issues)

NS&I occasionally offers fixed-rate Guaranteed Growth Bonds and Guaranteed Income Bonds, typically 1, 2, 3 or 5-year terms. These come and go — sometimes available, sometimes withdrawn from sale. Rates are typically below the best commercial fixes when available.

• British Savings Bonds: NS&I’s post-2024 rebranding of certain fixed-rate offerings — terms and rates have varied since launch.
• Maximum holdings: typically £1m per bond Issue per person.
• Interest: paid at end of term (Growth) or monthly (Income).

When NS&I fixed products are on sale, they’re sometimes the most competitive fix in the market — particularly when the government has a borrowing target it wants to hit through retail savings. When they’re withdrawn from sale, you can’t open new ones until a new Issue launches.

Worth checking the NS&I product list when looking for fixed-rate options — particularly above the FSCS £85,000 limit.

Direct ISA and Junior ISA

NS&I also offers an ISA:

• Direct ISA: easy-access cash ISA, government-backed. Rate is usually lower than the best commercial cash ISAs.
• Junior ISA: cash ISA for under-18s.

For the ISA wrappers specifically, NS&I’s government guarantee is a less distinctive benefit, because cash ISAs at commercial banks are also FSCS-protected up to £85,000 (which most people’s ISA holdings sit below). The rate gap to commercial alternatives is the bigger consideration.

Premium Bonds for children

There’s also a specific Premium Bonds variant where bonds can be bought by a parent or grandparent for a child, with prizes paid into a designated account. The child owns the bonds.

This is sometimes used as a tax-free saving vehicle for a child, but a Junior ISA usually offers better expected returns with no prize-fund variance — most considered modern approaches favour the Junior ISA over child Premium Bonds.

The headline trade-off

The trade-off across all NS&I products is the same: government-backed safety in exchange for typically lower rates.

For amounts under £85,000 — most savers’ situation — the trade-off doesn’t apply. Commercial banks are FSCS-protected, the safety is equivalent in practice, and the rates are better. NS&I products are typically not the right choice.

For amounts above £85,000 with a single banking licence, the question changes. The alternative to NS&I is splitting cash across multiple banking licences to keep each below the FSCS limit. Both routes work; NS&I is administratively simpler, the commercial split usually pays slightly more.

The specific NS&I product that often makes sense even below the FSCS limit is Premium Bonds for higher-rate taxpayers — the tax-free prize structure can beat after-tax returns from commercial accounts in some scenarios. For other NS&I products, FSCS-protected commercial alternatives usually win on rate.

The IHT angle for older savers

A specific consideration for older savers building substantial estates: cash held with NS&I sits inside your estate for IHT purposes the same as cash held with any bank. There’s no IHT advantage to NS&I.

What NS&I does offer is administrative simplicity for executors — a single Treasury-backed counterparty rather than multiple bank relationships. For estates running into significant cash holdings, this is a minor but real factor.

The bigger picture

NS&I is a specialised tool, not a default. Most savers shouldn’t hold cash with NS&I when better-rate commercial alternatives exist within the FSCS protection.

But for the specific situations where it fits — substantial cash above £85,000 needing administrative simplicity, Premium Bonds for higher-rate taxpayers wanting tax-free returns, or when a particular NS&I fixed-rate Issue is best-in-market — the products are clean, simple and backed by the safest counterparty in the country.
