This guide explains the difference between a fixed-rate savings bond and a mini-bond, and how to tell which one you are being offered. It is not financial advice or a recommendation of any product.
Overview
"Bond" is doing two completely different jobs in UK retail finance, and the gap between them is the difference between a protected deposit and an unsecured loan to a company you have never heard of.
A fixed-rate savings bond from a bank or building society is a deposit. The money is protected by the Financial Services Compensation Scheme, the rate is contractual, and the worst realistic outcome is that you cannot reach the money early without a penalty.
A mini-bond is a debt security: you lend to a business, which promises interest and repayment of capital. There is no deposit protection, no ringfencing of your money, and if the business fails you are an unsecured creditor in its insolvency.
Both were advertised, for years, using the same vocabulary — "fixed rate", "fixed term", "guaranteed returns", "income bond".
Quick Answer (Read This First)
| Fixed-rate savings bond | Mini-bond | |
|---|---|---|
| What it is | A deposit with a bank or building society | An unsecured loan to a company |
| Protection if the provider fails | FSCS, up to £120,000 per person per authorised firm | None in most cases |
| Who is regulated | The deposit-taker, and the deposit itself | Sometimes the seller; the bond itself typically not |
| Rate | Contractual, paid from the provider's funds | A promise, paid only if the business can |
| Early exit | Restricted, usually with a penalty | Often none at all until maturity, if then |
If a "bond" is paying several percentage points more than the best savings rates available, that difference is the market pricing risk you would be taking. It is not an oversight in your favour.
Why the Confusion Was Not Accidental
Mini-bonds were marketed at savers, not investors, and the language was chosen accordingly. Firms used the word "bond" alongside "fixed rate", "fixed term" and "capital growth" — the exact vocabulary of the fixed-rate savings market — while selling something structurally closer to lending money to a start-up.
The collapse of London Capital & Finance in 2019 made the consequences public. LCF was an FCA-authorised firm, which many bondholders reasonably took as assurance. The mini-bonds it sold were not regulated products, and most bondholders were not eligible for FSCS compensation. The government eventually established a separate statutory scheme under the Compensation (London Capital & Finance plc and Fraud Compensation Fund) Act 2021, paying eligible bondholders a proportion of what FSCS compensation would have been, subject to a cap.
The regulatory response followed. The FCA introduced a temporary ban on the mass-marketing of speculative illiquid securities, including speculative mini-bonds, to retail investors in January 2020, and confirmed permanent rules that took effect on 1 January 2021 under policy statement PS20/15.
The ban restricts how these products can be promoted to ordinary retail investors. It does not make every mini-bond disappear, and it does not retrospectively protect anyone who already holds one.
The Three Questions That Separate Them
1. Is the money a deposit? Only deposits with an authorised bank or building society are covered by FSCS deposit protection — currently £120,000 per person per authorised institution for firms failing on or after 1 December 2025. If the firm is not taking your money as a deposit, that limit is irrelevant to you no matter how prominently the FSCS logo appears elsewhere on the site.
2. Who is on the FCA Register, and for what? A firm being FCA-authorised is not the same as the product being regulated or protected. This is precisely the gap LCF investors fell into. Check the FCA Register for what the firm is actually permitted to do, and treat "FCA-authorised" in marketing copy as a claim to verify rather than a guarantee to rely on.
3. What happens if the issuer fails? With a savings bond, FSCS pays out. With a mini-bond, you join the queue of unsecured creditors, typically behind secured lenders and HMRC. Recovery in that queue is frequently a small fraction of capital, and it arrives years later.
Where Other "Bonds" Sit
The word covers several other things, none of them deposits:
- Gilts — UK government debt, tradeable, no FSCS deposit cover, but backed by the government's own creditworthiness.
- Corporate and retail bonds — tradeable debt in listed companies. Regulated markets, real prices, still no deposit protection.
- Investment bonds — insurance-based investment products, an entirely different regime again.
- NS&I products using the word bond, such as its guaranteed growth and income products, which are backed by HM Treasury rather than the FSCS. That backing is why NS&I sits outside the £120,000 question altogether.
- Premium Bonds — no interest at all, a prize draw, and Treasury-backed. Covered in our comparison of Premium Bonds and guaranteed interest.
If You Already Hold One
Check what you were actually sold: the offer document will say whether the instrument is transferable, whether it is secured on anything, and who the issuer is. Then check the issuer's filed accounts at Companies House.
If it was sold by an FCA-authorised firm and you believe the sale was misleading, the Financial Ombudsman Service can look at the sale even where the product itself was unregulated. Where the firm has failed, the FSCS may still consider a claim relating to regulated advice given about the investment — a different question from whether the bond itself was protected.
