Alongside the legitimate, FCA-regulated market for bad credit and specialist lending, an illegal "loan shark" market continues to operate in parts of the UK, targeting people who feel they have no other borrowing options. Knowing the warning signs — and where to turn instead — can make a genuine difference.
What makes a lender illegal or predatory?
In the UK, any business or individual lending money commercially must be authorised by the Financial Conduct Authority. Illegal money lenders — often called loan sharks — operate outside this regulation entirely, meaning none of the consumer protections that apply to regulated credit (clear terms, fair treatment, affordability checks, a right to complain to the Financial Ombudsman Service) apply to their lending.
Common warning signs
- No paperwork, or vague terms. Legitimate lenders are legally required to provide clear written credit agreements — an absence of proper documentation is a major red flag.
- Confiscating bank cards, passports or other identity documents as "security" — this is illegal and a strong indicator of an unregulated lender.
- Unclear or escalating interest that doesn't match any stated APR, or interest that seems to change arbitrarily.
- Threats or intimidation around repayment, including threats of violence — a clear sign of illegal activity that should be reported immediately.
- Lending sourced through informal community networks rather than a proper application and credit assessment process.
- Refusal or inability to confirm FCA authorisation when asked directly, or a firm name that doesn't appear on the FCA register.
How to check if a lender is legitimate
Before borrowing from any lender you're not already familiar with, search the Financial Conduct Authority's Financial Services Register (available on the FCA's own website) to confirm the firm is authorised for consumer credit activities. If a "lender" isn't listed, or claims to be exempt without a clear, verifiable explanation, treat this as a serious warning sign and do not proceed.
Predatory practices within the regulated market
It's also worth being aware that even regulated lenders can, in some cases, use aggressive or borderline sales practices — high-pressure upselling of loan top-ups, encouraging borrowing beyond what's genuinely needed, or unclear communication about total costs. These practices, while operating within regulation, still deserve scrutiny; you're entitled to take your time, ask questions, and walk away from any lending decision that doesn't feel right.
What to do if you think you've encountered a loan shark
- Stop making any further payments if you're being intimidated or threatened, and seek immediate safety if you feel at risk.
- Report it to the Illegal Money Lending Team (England: 0300 555 2222) or the equivalent service in Scotland, Wales or Northern Ireland — these teams investigate illegal lending and can offer support, confidentially and without judgment.
- Contact a free debt charity such as StepChange or National Debtline for confidential advice on your wider financial position.
- Report threats or violence to the police directly if you're in immediate danger.
Safer alternatives if you're struggling to access mainstream credit
- Credit unions, which are specifically set up to serve people mainstream lenders decline, at regulated, capped interest rates
- Local council welfare assistance schemes or crisis grants
- Free, confidential advice from a debt charity before taking on any new borrowing

The bottom line
Illegal lending preys specifically on financial vulnerability, using tactics that regulated lenders are legally prohibited from using. Knowing the warning signs, checking FCA authorisation before borrowing from any unfamiliar lender, and knowing where to turn for free, confidential help are the most powerful protections available to UK consumers.
