The UK application window opens on 30 September 2026 and closes on 28 February 2027. After it, carrying on cryptoasset activities in or to the UK without FCA permission under FSMA will not be lawful — the new regime bites by 25 October 2027. Firms that file inside the window may benefit from transitional provisions while the FCA decides.
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. Miss the window and you are not simply late — you are applying from outside the transitional shelter, with your UK activity in question while the file is assessed.
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.
