Britain’s cryptoasset firms finally have a date to build towards. The Financial Conduct Authority’s authorisation gateway, the point at which firms can formally apply for permission under the new regime, is expected to open on 30 September 2026 and to close on 28 February 2027. That five-month window is the operational on-ramp to a regime that only becomes mandatory more than a year later, and it is the moment the industry’s regulatory clock actually starts to run.
The dates matter because they are firm in a way most of this process has not been. The FCA has said it expects the application period to run from 30 September to 28 February, as set out in its formal direction, language that signals a fixed timetable rather than an aspiration. The final rules underpinning the regime were published on 30 June 2026. What follows is a scheduled sequence: apply inside the window, secure authorisation, and be ready for the switch-on.
That switch-on date is 25 October 2027. The FCA’s final rules will apply to every cryptoasset firm granted permission under the Financial Services and Markets Act on or after that day. In practice the gateway and the switch-on are two ends of one bridge. A firm that wants to be trading, safeguarding or issuing on day one of the mandatory regime has to cross through the gateway in the months before it, not after.
Who the regime catches
The scope is deliberately wide. The regime covers firms carrying on in-scope cryptoasset activities in or to the UK: operating a trading platform, dealing in and arranging deals in qualifying cryptoassets, safeguarding cryptoassets, issuing a qualifying stablecoin, and staking. A firm does not have to be based in Britain to be caught; providing these services to UK users is enough. That reach is the point. The government and the FCA have framed the regime as the foundation of the UK’s pitch to be a global hub for cryptoasset business, and a hub needs a perimeter that binds anyone selling into it.
For firms already inside Britain’s existing arrangements, the gateway carries a blunt message: there is no free pass. Cryptoasset businesses registered with the FCA under the Money Laundering Regulations will not be converted automatically. They will have to win fresh authorisation under the Act, on the same timetable as everyone else. Firms authorised under the Payment Services Regulations or the Electronic Money Regulations, and existing FSMA-authorised firms that want to add cryptoasset permissions, are in the same position. The registration a firm holds today is not the permission it will need tomorrow.
The perimeter firms cannot yet map
Here is the part firms still cannot fully answer for themselves: exactly where the perimeter falls. The FCA consulted on that question in CP26/13, its cryptoasset perimeter guidance, setting out the regulator’s reading of the activities in scope, from issuing a qualifying stablecoin to operating a trading platform, dealing and arranging, safeguarding and staking. That consultation closed on 3 June 2026. The final policy statement that clarifies which activities sit inside the boundary is due in autumn 2026, which is to say around the time the gateway opens, not before it.
The timing is awkward. A firm preparing an application in September has to decide which permissions to seek against guidance that may only be finalised as the window opens. For the clearest cases, a spot exchange, a custodian, a stablecoin issuer, the answer is not in doubt. The harder questions sit at the edges: whether a particular staking arrangement is caught, how an intermediary’s arranging activity is treated, where a borderline product lands. Those are the firms for which the perimeter statement, not the gateway date, is the real gating event.
A front-loaded model
None of this makes the timetable soft. The FCA has given the industry the two fixed points it asked for, an opening date and a switch-on date, and has published the rulebook that sits between them. The message is that preparation cannot wait for every question to be settled. Building an authorisation application takes months, and the window is only five of them. A firm that waits for the perimeter statement to be final before it starts work risks running the two processes in parallel under time pressure, rather than in sequence.
The wider read is that Britain has chosen a front-loaded model. Rather than let the existing anti-money-laundering registration harden into a de facto licence, the FCA has drawn a clean line: a new regime, a single authorisation route, and a hard date on which the old registration stops being enough. It is a more demanding path than automatic conversion, and a more defensible one for a regulator that wants the UK’s crypto perimeter to mean something to firms beyond its borders as well as inside them.
For now the number that matters is 30 September. That is when the clock the industry has watched for two years finally starts to run, and when the gap between holding a registration and holding the right authorisation turns from a future problem into a live commercial one.
