The UK application window opened on 30 September 2026 and closes on 28 February 2027. Once the new regime starts (the FCA expects 25 October 2027), cryptoasset activities in or to the UK without FCA permission under FSMA are possible only under an exemption, the saving provision or the transitional provision. As a rule, firms that file inside the window can keep operating until the FCA finally determines the application.
The filing date decides how a firm operates when the regime starts if its application is still undecided. An application made by 28 February 2027 lets the firm keep operating until the FCA finally determines it. After a refusal that is still open to review, the FCA may in certain cases direct the firm into the transitional provision instead. An application made after the window but before the regime starts (25 October 2027, as the FCA expects) puts the firm into the transitional provision: pre-existing contracts only, no new contracts with UK customers, and up to two years to run off UK business. A firm that has not applied before the regime starts has to run off its UK business by then. Dates, table and preparation steps: FCA crypto authorisation window 2026–2027.

Most licensing decisions can wait a quarter. This one cannot. The FCA has set a fixed gateway: applications are accepted from 30 September 2026 until 28 February 2027, and firms already operating are expected to be inside it. File after the window but before the regime starts, and from that start your UK business is limited to pre-existing contracts while the FCA assesses the file.
Five months sounds generous until you price the preparation. A full-scope application asks for senior management accountability, prudential resources, custody and safeguarding controls, market abuse surveillance where relevant, operational resilience and a credible wind-down plan. That is a documentation project.
The perimeter is territorial in both directions: activity in the UK and activity to UK clients from abroad are both caught. An overseas exchange onboarding UK retail customers falls inside the regime.
The anti-money-laundering registration with the FCA has existed since January 2020 and is not replaced on day one. In practice the FCA expects a firm to have its MLR position sorted before a FSMA application, and expects most applicants to operate through a UK legal entity. If you have neither, budget the first two months of the project for building them.
Since October 2023, marketing cryptoassets to UK consumers has required an authorised person's approval, a risk warning and a cooling-off period for new customers. Firms often discover this only when a campaign is pulled. If you advertise to UK users today, that exposure exists today — independently of the FSMA gateway.
We establish whether your activity is caught, which permissions you need and whether you must be a UK entity. Some models are better served from an EU MiCA authorisation — if that is your case, we will say so rather than sell you a UK file.
