Every UK payments provider markets itself as "secure" and "regulated", but the words mean different things depending on who is using them. The line that actually matters — the one with legal weight, financial protection, and consequence if breached — is whether the firm holds its own FCA authorisation. For UK merchants signing a payments contract in 2026, that is the single most important diligence question.

What FCA authorisation actually is

The Financial Conduct Authority is the UK regulator for payment institutions, e-money institutions, and a range of related activities. A firm authorised by the FCA holds either an Authorised Payment Institution (API) or Authorised Electronic Money Institution (AEMI) permission, gets a unique Firm Reference Number (FRN), and is listed on the public FCA Register. The authorisation is granted only after the regulator has reviewed the firm's capital, governance, anti-money-laundering controls, safeguarding arrangements, and the people running it.

Once authorised, the firm is subject to ongoing supervision: capital requirements, mandatory reporting, periodic audits, the new safeguarding regime that took effect on 7 May 2026, and direct regulatory oversight of how customer funds are held and protected.

"Regulated" vs "authorised" — and the agent loophole

Many UK payment brands are not directly authorised in their own right. Instead, they operate as agents of an authorised firm — sometimes a UK acquirer, sometimes an overseas e-money institution passporting in under previous EEA arrangements. The agent gets to advertise "FCA regulated" and appears on the register, but the legal obligation for safeguarding your funds sits with the principal, not the brand on your statement.

That distinction matters in two situations: when the agent fails (your funds are protected by the principal's segregation, not the agent's), and when you want to switch (your contract is often with the agent but settlement runs through the principal). It is not automatically a bad thing — many large UK gateways operate this way — but you should know which side of the line your provider sits on before you sign.

What FCA authorisation actually gives a merchant

Beyond a marketing badge, direct FCA authorisation gives you four real, contractual protections:

  • Safeguarded funds — your float between transaction capture and settlement must be held in a designated trust account at a UK bank, separate from the firm's operating money. Under PS25/12, these accounts are now reconciled daily and audited annually.
  • Capital adequacy — authorised firms must hold ongoing regulatory capital sized against transaction volume. This is the regulator's way of ensuring the firm cannot trade insolvent.
  • Right to complain to the Financial Ombudsman Service — eligible merchants get free, binding dispute resolution if the firm acts unreasonably.
  • Resolution plan — if the worst happens, there is a structured process for returning customer funds, rather than queuing as an unsecured creditor in administration.

How to verify a provider in 90 seconds

Whatever a payments salesperson tells you, the FCA Register is the source of truth. Three checks tell you everything you need:

  • Search the FCA Register at register.fca.org.uk by company name. Note the FRN.
  • Read the permissions — does the firm hold "Issuing of electronic money" or "Acquiring of payment transactions" itself, or is it listed as an agent of another firm?
  • Confirm the FRN on the provider's website — every authorised firm must publish its FRN. If a "regulated" payment company will not give you a number, that is your answer.

How Monek sits in this picture

Monek is directly FCA-authorised as a payment services provider — FRN 920628 — with all merchant funds safeguarded in designated UK trust accounts, reconciled every business day, and audited annually under the new PS25/12 regime. We are not an agent of anyone, which means the protections above flow directly from us to you, not from a chain of intermediaries.

If you would like a plain-English read of how your current provider compares — whether they are authorised in their own right, what their FRN is, and what that means for your float — our team will review your current contract at no cost and tell you exactly where you stand.
