Overview

What an FCA authorisation actually gives a UK retail trader, and what it does not.

Every firm listed on this site holds a live authorisation you can verify on the Financial Services Register. That single sentence does more work than any amount of marketing language about "regulated and trusted", a phrase which appears on the websites of firms with no UK permissions at all.

The rest of this page is written for the moment it matters: when you are about to deposit, when something has gone wrong, or when a broker's answer does not sound right. Each point below is a rule you can check for yourself against public sources.

  • Verify the entity on the Financial Services Register before depositing
  • Read which company name appears in the account terms
  • Keep your own records of trades, statements and correspondence
  • Protections apply to firm failure and misconduct, never to losing trades

Authorisation is not endorsement

The regulator authorises a firm to carry on a regulated activity. It does not vet the quality of the pricing, the platform or the support, and it never guarantees that you will make money.

In practice this is where the difference between firms shows up. Two brokers can both be authorised and still handle the same situation very differently, because the rule sets a floor rather than a standard. When we score a firm on regulation and safety, we look at how far above that floor it chooses to operate: how clearly it names its entity, how specific its disclosure is, and how it behaves when a client disputes something.

Check the entity, not the brand

Large groups run several entities. The website you land on may be operated by an offshore company while a separate UK entity holds the FCA permission. The protections follow the entity that holds your money.

Permissions matter

A firm may be authorised to arrange deals but not to hold client money, or to deal as agent but not as principal. The register lists the exact permissions, and they tell you how the business is really structured.

Appointed representatives

Some firms operate under another company's licence as an appointed representative. That is legal, but the responsibility sits with the principal firm, which is worth knowing before you deposit.

Regulation

  1. What does this actually protect me from?

    Every firm listed on this site holds a live authorisation you can verify on the Financial Services Register. It applies to the failure or misconduct of an authorised firm, not to the outcome of your trades.

  2. How do I check a broker qualifies?

    Search the Financial Services Register by firm name and reference number, confirm the permissions and trading names, and check the entity named in the account terms is the same one.

  3. Does it apply to offshore entities of UK brands?

    No. Protections follow the authorised entity. An offshore arm of a familiar brand sits outside the FSCS, the Ombudsman and the UK retail rules, whatever the website looks like.

  4. Am I covered as a professional client?

    Elective professional clients give up several retail protections, including negative balance protection and the retail leverage caps, and often access to the Ombudsman. That trade is rarely worth it for private money.

  5. What if my broker gets it wrong?

    Complain in writing to the firm first. If you are unhappy with the final response, or eight weeks pass without one, the Financial Ombudsman Service can consider the case free of charge.

  6. Authorisation is not endorsement?

    The regulator authorises a firm to carry on a regulated activity. It does not vet the quality of the pricing, the platform or the support, and it never guarantees that you will make money.

Risk warning

CFDs and spread bets are leveraged products and the majority of retail accounts lose money. Figures on this page are researched from firm documentation and live accounts, but pricing, funding routes and account terms change without notice. Check the broker's own terms and the Financial Services Register before you deposit, and never risk money you cannot afford to lose.
