Mini-Bond Investment Risks UK: What Went Wrong and How to Claim
UK mini-bonds were unregulated, high-risk lending instruments marketed to ordinary savers as low-risk fixed-rate ISAs. After collapses at London Capital & Finance, Blackmore Bond and Basset & Gold, the FCA banned the mass marketing of speculative mini-bonds to retail investors. Investors can recover losses via the FSCS (up to £85,000 per claim), the dedicated HM Treasury LCF compensation scheme, or directly against the regulated firm that approved the financial promotion.
What is a mini-bond?
A mini-bond is a non-transferable debt security issued by a single company to fund its business, typically promising fixed annual returns of 6–12%. Crucially, mini-bonds are not regulated investments under the Financial Services and Markets Act 2000 (FSMA), meaning investors do not get the same protections as with shares, bonds or funds.
Between 2015 and 2019, mini-bonds were aggressively marketed to ordinary UK savers — often through Google ads, comparison sites and unregulated introducers — as low-risk, ISA-eligible fixed-rate products. The reality was concentrated lending to a single high-risk business or onward-investment into speculative property.
The major collapses
London Capital & Finance (LCF) — collapsed January 2019, more than £237 million lost across 11,600 investors. The FCA was found by the Gloster Review to have failed in its supervisory duties.
Blackmore Bond — collapsed April 2020, around £46 million lost across 2,800 investors.
Basset & Gold — collapsed April 2020, around £36 million lost across 1,800 investors.
All three were heavily promoted as ISA-eligible 'Innovative Finance ISAs' — a category that does not, in law, reduce capital risk.
How investors are compensated
FSCS route: where a regulated adviser recommended the mini-bond, or where the bond promoter relied on a regulated 'principal' firm to approve its financial promotions (Section 21 FSMA), claims can be made against the FSCS up to £85,000 per claim. Many LCF and Blackmore investors have already recovered via this route.
HM Treasury LCF scheme: a dedicated government scheme pays 80% of LCF losses up to £68,000 to most investors. Some claimants top this up via FSCS against the principal firm Surge Financial Limited.
Direct claims: where the regulated firm is still trading, you can pursue uncapped losses against it and its PI insurer through FOS or the courts.
Were you mis-sold?
You may have a claim if: you were promised fixed returns of 6%+ and told the bond was 'low-risk' or 'ISA-safe'; you were a retail investor rather than a certified sophisticated or high-net-worth investor; you were not warned that your capital was at risk or that FSCS did not cover the underlying investment; or you used pension or ISA savings to invest.
Even if you have received an interim FSCS or LCF scheme payment, it is worth checking whether you have an outstanding shortfall — full FSCS recovery (£85,000) and adviser-led claims often exceed the interim figure.
What to do next
Don't assume the matter is closed if you have already received a partial payment. Gather your investment paperwork — application form, ISA transfer authority, promotional brochure, any adviser correspondence — and submit a free claim check. Most mini-bond claims resolve in 6–12 months on a No Win, No Fee basis.
