Investment fraud is the fastest-growing category of financial crime in the UK. In 2025, Action Fraud received over 17,000 reports — and that is only the cases that were actually reported. The average loss per victim is £29,000. In the most sophisticated scams, individual losses exceed £500,000.
What makes investment fraud particularly devastating is that victims are often financially literate people who believe they are making an informed decision. The scam is designed to look like a real opportunity. Understanding the warning signs is the only reliable defence.
The 8 warning signs of investment fraud
- Guaranteed returns. All legitimate investments carry risk. Any investment that guarantees a specific return — especially one significantly above savings rates — is either fraudulent or the person offering it does not understand what they are selling. Both outcomes require you to walk away.
- Unsolicited contact. Cold calls, texts, emails, LinkedIn messages, or social media DMs promoting investment opportunities. Regulated financial firms do not cold-contact members of the public to offer investments. If they found you, ask yourself how and why.
- Pressure to invest quickly. "This opportunity closes today." "Only 5 places remaining." "I can only hold your slot until Thursday." Urgency is used to prevent you from taking the time to verify. Legitimate investments do not disappear overnight.
- The company is not on the FCA register. Any firm offering financial investments or advice to UK customers must be authorised by the Financial Conduct Authority. Check register.fca.org.uk before investing. If they are not on it, stop.
- You can only get your money back after paying a fee. This is the final stage of most investment scams. Once you try to withdraw, you are told taxes, insurance, fees, or "exit bonds" must be paid first. This money is also stolen. There is no investment product in existence where you must pay upfront to access your own funds.
- Unusually high but consistent returns shown in a dashboard. Many fake trading platforms show your "investment" growing smoothly in real time. You may even be allowed to make small withdrawals to build confidence. This is manufactured credibility — the platform and the returns are entirely fake.
- The investment is in cryptocurrency, foreign exchange, or "exclusive" opportunities. These are the sectors most used in investment fraud because they are harder to verify and regulation is less familiar to victims. This does not mean crypto or forex are inherently fraudulent — but they are the category where fraudulent schemes are most concentrated.
- Someone you met recently is the one recommending it. The "pig butchering" scam starts with a relationship — romantic or friendly — that develops over weeks before any investment is mentioned. If someone you have never met in person is recommending an investment, that is not an opportunity. It is a well-practised con.
Pig butchering: the long-con that costs the most
Pig butchering is an investment scam that begins with a relationship. The term comes from Chinese-language fraud forums — the idea is to "fatten the pig before slaughter." A scammer invests weeks or months building trust and emotional connection before introducing an investment platform they claim to use personally.
The platform looks professional. Your investments appear to grow. Small withdrawals are permitted to build confidence. When you invest a significant sum — often your savings, a remortgage, or borrowed money — the platform freezes your account and demands taxes or fees. There is no way to recover the funds. The platform, the profits, and often the person who introduced you are all fabricated.
Individual losses from pig butchering have reached £800,000 in UK cases. It is the most financially damaging variant of investment fraud in operation.
Clone firm fraud
A clone firm copies the name, logo, address, and FCA registration number of a real, legitimate financial firm. When you search the company and find it on the FCA register, you believe you are dealing with a regulated firm. You are not — the cloned firm uses the legitimate firm's details as a veneer.
To detect this: always contact the firm using details from the FCA register directly, not contact details provided by the person who approached you. The FCA also maintains a specific Warning List of clone firms at fca.org.uk/scamsmart.
The FCA Check — the one verification you must do
Before committing any money, check the FCA Register at register.fca.org.uk. Enter the firm's name. If they are not listed, do not invest. If they are listed, contact them using the phone number and address on the FCA register — not the contact details you were given.
Also search the FCA Warning List for the firm's name — it lists firms already identified as scams or operating without authorisation.
