A broker authorised by the UK Financial Conduct Authority operates under one of the most protective rulebooks available to a retail trader: client money held on trust under the CASS rules, compensation of up to £85,000 through the FSCS if the firm fails, negative balance protection on every retail CFD account, leverage capped at 30:1, and a complete ban on deposit bonuses. Those protections are real, and in past broker failures they have paid out. They also attach to one specific legal entity — not to a brand, a platform, or a familiar logo.
That last point drives everything else in this guide. The two most common ways traders lose money “with an FCA broker” involve no FCA broker at all: clone firms that quote the genuine registration number of a real company, and offshore sister entities that share a brand’s name but none of its UK obligations. Regulation is the heaviest-weighted input in how we rate brokers, and the checks below are the same ones we run before any rating is assigned. Every figure in this article was re-verified in July 2026; these numbers change, so treat the date as part of the fact.
What the FCA is and what it actually does
The Financial Conduct Authority is the United Kingdom’s conduct regulator for financial services. It is a public body, funded by fees charged to the firms it regulates, and Parliament has given it three statutory objectives: protect consumers, protect the integrity of UK markets, and promote effective competition. In practical terms, that mandate translates into four activities a trader can observe directly — the FCA decides who may operate (authorisation), writes the rules they operate under, supervises whether those rules are followed, and punishes firms when they are not.
Two features distinguish it from lighter regimes. First, it holds product intervention powers: it can restrict or ban a product for retail consumers outright, which is exactly how the CFD leverage caps and the retail crypto-derivatives ban came into force. Second, accountability is personal — under the Senior Managers regime, named individuals at a broker are answerable for specific failures, and since 2023 the Consumer Duty has required firms to evidence that retail customers actually get good outcomes, not merely compliant paperwork.
What the FCA is not is a guarantor. It does not vet prices in real time, endorse any firm’s quality, or promise that an authorised broker will never fail or misbehave. It raises the floor; it does not remove the risk.
What FCA authorisation obliges a broker to do
For a retail CFD and forex broker, authorisation is not a badge — it is a bundle of enforceable obligations. The ones that matter most to your deposit are these:
- Client money segregation (CASS). Your balance must be held on trust in designated client bank accounts, legally separate from the broker’s own money, with strict reconciliation obligations. In an insolvency, that pool is returned to clients ahead of general creditors — and it covers the full balance, not a capped amount.
- FSCS membership. If the firm fails and client money comes back short, the Financial Services Compensation Scheme pays investment claims up to £85,000 per person, per authorised firm, as verified in July 2026. Note that the better-publicised £120,000 figure is the bank deposit limit, raised in December 2025 — a different scheme that does not apply to brokerage claims.
- Negative balance protection. A retail CFD account cannot go below zero. Whatever happens overnight or through a price gap, the most you can lose is what is in the account.
- Automatic margin close-out. The broker must close positions once your funds fall to 50% of the margin required to keep them open, limiting how deep a losing position can dig.
- No bonuses or trading incentives. Deposit bonuses, volume rewards, and similar inducements to trade CFDs are banned for retail clients. A “UK-regulated” broker offering you a deposit bonus is, by definition, not serving you from its UK entity.
- Standardised risk disclosure. Each firm must display the percentage of its own retail accounts that lose money — one of the few marketing statements a broker publishes against its interest.
Leverage caps are tiered by how volatile the underlying instrument is, and they apply to every retail client of the UK entity regardless of where that client lives:
| Instrument class | Maximum retail leverage |
|---|---|
| Major currency pairs | 30:1 |
| Non-major currency pairs, gold, major stock indices | 20:1 |
| Commodities other than gold, non-major indices | 10:1 |
| Individual shares and other reference values | 5:1 |
| Crypto-derivatives | Sale to retail clients banned entirely |
If a broker claiming FCA regulation quotes you 500:1 leverage or a crypto CFD, the arithmetic has already answered the question: whatever entity is making that offer, it is not the FCA-authorised one.
How to verify a broker on the FCA register, step by step
The Financial Services Register at register.fca.org.uk is the authoritative public record of who is authorised and for what. It is free and takes about five minutes to use properly — but it has to be used the way fraud actually works, which means searching by number and comparing details, not merely confirming that a name exists.
- Get the Firm Reference Number, not the name. Every authorised firm has a unique FRN, usually printed in the website footer and in the client agreement. Names are easy to imitate and easy to confuse — several legitimate firms have near-identical names — so the FRN is the only identifier worth searching.
- Search the register by that FRN. Type the number into the register’s search box and open the firm’s record. If the FRN returns nothing, or returns a firm in a completely different business, stop here.
- Check the status reads “Authorised”. Entries can also show lapsed, cancelled, or registered-only statuses. An e-money or payment services registration is not authorisation to run a brokerage, and an appointed representative is not directly authorised at all.
- Open the permissions and look for “dealing in investments”. A CFD broker’s record should include dealing in investments as principal or as agent, alongside permission to hold client money. A firm whose permissions cover only advising or arranging is not permitted to run your trading account.
- Compare the register’s contact details against the site soliciting you. The register lists the firm’s recorded website domain, phone number, and address. If the site that approached you uses a different domain, a different phone number, or “updated” contact details, treat it as a clone until proven otherwise — this comparison, not the FRN lookup alone, is the step that catches clones.
- Cross-check the Warning List, and call back through the register. Search the firm and domain on the FCA’s Warning List. If anything feels off, contact the firm only through the phone number shown on the register — never through the number on the site that contacted you.
The Warning List and the clone-firm problem
The most effective broker frauds do not invent a licence — they borrow one. A clone firm takes the name, registered address, and genuine FRN of a real FCA-authorised company, builds a convincing website, and changes only the details that route your money: phone numbers, email addresses, payment accounts. When a target checks the register, the FRN resolves to a real firm, and the check appears to pass. Criminals actively encourage that lookup because it converts the FCA’s own register into their credibility.
The scale is not marginal. In the first half of 2025 alone, the FCA received close to five thousand reports of scams impersonating the regulator itself, and UK police have attributed tens of millions of pounds in annual losses to clone-firm investment fraud. The FCA’s Warning List — its running record of unauthorised firms and known clones — is updated daily, but it is reactive by nature: a clone appears on it only after someone has reported it. Absence from the Warning List is not clearance.
The defensive posture follows from the mechanics. A firm you found and contacted yourself, verified by FRN with matching register details, carries low clone risk. An unsolicited approach — a call, a social media message, a “recovery agent” offering to retrieve earlier losses — that volunteers an FRN as proof is the classic clone pattern, and the quoted number being genuine makes it more suspicious, not less.
What FCA regulation does not protect you against
The protections above are narrower than broker marketing implies, and the gaps are where most disappointment happens:
- Trading losses. The majority of retail CFD accounts lose money — the firms’ own mandated disclosures say so. The FSCS compensates you when a failed firm cannot return your money; it pays nothing for losing trades at a solvent one. No regulator underwrites your strategy.
- The offshore sister entity. Most large CFD brands operate several legal entities: an FCA-authorised company in London and siblings in, say, Seychelles or Belize. Open your account with the offshore entity — or accept an offer to “upgrade” to higher leverage — and every UK protection on this page evaporates, while the logo on your platform stays identical. The entity named in your account agreement matters more than the brand, and this is the single most consequential line in your paperwork.
- Ordinary poor service. Wide spreads at news time, slow withdrawals that still complete, rejected orders during volatility — these are quality problems, not usually rule breaches. The Financial Ombudsman Service can hear complaints against UK firms free of charge, but it resolves disputes after the fact and on a timescale of months.
- Everything above £85,000. Segregation protects the full balance while it holds; the FSCS backstop is capped. A balance materially above the limit at a single firm carries uninsured tail risk that diversifying across separately authorised firms would reduce.
The enforcement record with CFD brokers
A rulebook is only as good as its consequences, so it is worth checking whether the FCA actually moves against CFD firms. As verified in July 2026, the recent record says it does — and, tellingly, for failures in the plumbing rather than the headlines:
- Infinox Capital, January 2025. Fined £99,200 for failing to submit 46,053 transaction reports for single-stock CFD trades — the first fine ever issued under the UK’s MiFIR transaction reporting regime. Transaction reports are how the regulator sees market abuse, so gaps in them blind the whole system.
- Dinosaur Merchant Bank, 2025. Fined roughly £338,000 for inadequate systems to detect and report suspicious trading in its CFD business; the penalty would have been about £482,900 without the standard cooperation discount.
- Charles Schwab UK, December 2020. Fined £8.96 million for client money failures under the CASS rules — the largest recent penalty aimed directly at the mechanism that protects trader deposits.
Two honest caveats. The sums are small next to banking fines, because the firms are smaller. And enforcement is retrospective: investigations run for years, so a fine tells you the system works, not that today’s misconduct has already been caught. Even so, a regulator that audits transaction reports and client money reconciliations line by line is applying pressure exactly where a retail client needs it.
FCA vs CySEC vs ASIC vs offshore: the protections that differ
The three major retail regulators have converged on similar conduct rules, so the differences that remain are precisely the ones worth a table. Figures as verified in July 2026:
| Protection | FCA (UK) | CySEC (Cyprus) | ASIC (Australia) | Typical offshore (Seychelles, Belize, SVG) |
|---|---|---|---|---|
| Compensation scheme | FSCS — £85,000 per person, per firm | ICF — lower of 90% of the claim or €20,000 | No general investor scheme; narrow CSLR backstop | None |
| Client money rules | CASS trust segregation with strict reconciliation | Segregation required under MiFID rules | Statutory trust accounts | Varies; rarely verifiable |
| Retail leverage cap, major FX | 30:1 | 30:1 | 30:1 | Commonly 500:1 or more |
| Negative balance protection | Required by rule | Required by rule | Required by rule | Discretionary policy, if offered |
| Crypto CFDs for retail | Banned | Allowed at 2:1 | Allowed at 2:1 | Unrestricted |
| Deposit bonuses | Banned | Banned | Banned | Common |
| Free dispute service | Financial Ombudsman Service | Financial Ombudsman of Cyprus | AFCA | Rarely any practical recourse |
Read down the offshore column and the real divide is obvious: it is not FCA versus CySEC versus ASIC, where the differences are meaningful but bounded — chiefly compensation depth and enforcement intensity. It is regulated versus unregulated, where every row changes at once. This asymmetry is why the regulating entity behind your specific account dominates our scoring, and why no commercial relationship moves it — how we make money explains that separation in full.
Frequently asked questions
Is the FCA the strictest regulator for retail traders?
There is no official ranking, and the headline conduct rules — 30:1 leverage, negative balance protection, no bonuses — are now nearly identical across the FCA, CySEC, and ASIC. Where the FCA plausibly leads is the combination around those rules: the deepest compensation scheme of the three, an active enforcement record against CFD firms, personal accountability for senior managers, and a free ombudsman. “Strictest” in a broker’s marketing copy, though, deserves the same scrutiny as any other claim.
What happens if my FCA broker goes bust?
The firm enters an administration process in which segregated client money is identified, reconciled, and returned to clients ahead of general creditors. If the pool comes back short — through fraud, error, or administration costs — the FSCS tops up eligible claims to £85,000 per person. Expect the process to take months. Claims to the FSCS are free; anyone charging to “recover” your funds from a failed firm is running the follow-up scam.
How do I check if a broker is really FCA-regulated?
Take the FRN from the broker’s site, search it at register.fca.org.uk, confirm the status is Authorised with permissions that include dealing in investments, then compare the register’s recorded domain and phone number against the site soliciting you. A mismatch in contact details is a clone signal even when the FRN itself is genuine. Finish with a Warning List search.
Does the FCA cap leverage at 30:1 on everything?
No. 30:1 applies only to major currency pairs. Non-major pairs, gold, and major indices are capped at 20:1, other commodities and minor indices at 10:1, and individual shares at 5:1, while crypto-derivatives cannot be sold to retail clients at all. A single number in an advert is always the best case, not the general rule.
Does the FSCS cover my trading losses?
No. The FSCS pays only when an authorised firm fails and cannot return client money or assets. Losses from your own positions at a solvent broker are simply losses, and no UK scheme reimburses them.
Can an FCA-regulated broker still be a problem?
Yes, with lower probability than elsewhere. The enforcement cases above all involved authorised firms, and disputes over execution quality or withdrawal speed sit largely outside the rulebook. The more common trap, however, is contractual: signing up through a brand’s offshore entity while assuming the UK protections follow the logo. They do not. Verify the entity on your account agreement before you deposit, because that name — not the brand — decides which of this article’s protections you actually hold.
