On 30 September the Financial Conduct Authority opens its authorisation gateway for cryptoasset firms, and the application window closes on 28 February 2027. At first glance this is news for exchanges and custodians rather than for a UK retailer or ecommerce seller. But if anyone has pitched you stablecoin settlement, crypto acceptance at the checkout, or near-instant cross-border payouts in the past year, the next five months will decide whether that provider is still trading in the UK in 2028. It is worth knowing what to ask them.

What actually opens on 30 September

The FCA published its final rules for the cryptoasset regime on 30 June 2026, completing a roadmap that started with legislation in February bringing cryptoassets into the regulator's remit. Trading platforms, intermediaries, custodians, stablecoin issuers and firms arranging staking will all need authorisation under the Financial Services and Markets Act 2000 to operate here. The mandatory regime commences on 25 October 2027, and the FCA has confirmed the application period runs from 30 September 2026 to 28 February 2027.

Two details matter more than the headline. First, there is no automatic conversion. A firm registered with the FCA under the money laundering regulations does not carry that registration across, and a firm already authorised under FSMA for payment services or e-money still has to apply to vary its permissions. Second, until October 2027 the FCA's oversight of crypto stays limited to financial promotions and anti-money-laundering controls. A firm can appear on the Financial Services Register today and still be nowhere near authorised for the thing it is selling you.

The questions to put to any crypto-adjacent provider

The FCA has been unusually explicit about what happens to firms depending on when, or whether, they apply. That gives merchants a clean set of tests to run on a supplier:

  • Applied inside the window: the firm benefits from a saving provision and can keep serving UK customers while its application is determined. This is the only comfortable answer.
  • Applied late: the firm falls into the transitional provision by operation of law. It can only perform pre-existing contracts. It cannot take on new UK customers, and it cannot enter new contracts with the customers it already has.
  • Not applying: the firm must run off its UK business before commencement, with no saving or transitional cover. Continuing regardless risks breaching the general prohibition under section 19 of FSMA.
  • Ask for evidence, not intent: "we are working towards authorisation" is not an answer. Ask which regulated activities they are applying for, whether they have used the FCA's pre-application support service, and what happens to your balances if the application is refused.

If your business holds funds with that provider even briefly, the refusal scenario is the one to think hardest about. Ask where your money sits, who holds it, and under what protection.

Where this touches ordinary payments

The FCA is due to publish a further policy statement in September 2026 setting out how the regulatory perimeter applies to cryptoasset activities, which is the piece that determines exactly where payments regulation ends and crypto regulation begins. Commenting on the final rules, UK Finance said it looked forward to working with the regulator on how stablecoin payments will connect with the wider Modernising Payments Regulations programme. In other words, the two workstreams are converging, and the boundary is still being drawn.

David Geale, the FCA's executive director of payments and digital finance, framed the June rules as giving firms both regulatory certainty and room to innovate, while adding that the regulator cannot "regulate away risk". That is a fair summary of where merchants stand too. Authorisation raises the floor on conduct, capital and disclosure. It does not turn a novel settlement route into a mature one, and it does not answer the practical questions that decide whether a payment method earns its place at your checkout: whether customers ask for it, how disputes and refunds work, and whether the money reconciles cleanly into Xero or Sage at month end.

What to do this week

For the vast majority of UK businesses, nothing about the September gateway changes what you should do on Monday morning. Cards and Faster Payments already settle quickly and cheaply for domestic trade, and the biggest savings available to most merchants are still sitting in their existing statement rather than in a new rail. So the useful exercise is the unglamorous one: pull your last three months of processing charges, separate interchange from scheme fees from your provider's margin, and check whether the rate you were sold is the rate you are paying. If you do work with a crypto-adjacent supplier, add the four questions above to your next review call and diarise 28 February 2027.
