UK opens crypto authorisation gateway, firms face 2027 deadline

Britain's financial regulator opened its crypto authorisation gateway at 9am UK time on 30 September 2026. Firms that trade, hold or arrange digital assets for UK customers now have until 28 February 2027 to apply, or lose the right to serve those customers.

Guidance published on 16 September set out the timeline. The Financial Conduct Authority, known as the FCA, now runs the UK's first full licensing system for crypto. It replaces a lighter regime that only checked firms for money laundering risk.

What the gateway opens

The application window runs for five months. It opened at 9am UK time, which is 0800 UTC, on 30 September 2026 and closes at 11:59pm on 28 February 2027, according to the FCA. The rules themselves do not take effect until 25 October 2027, the day the mandatory regime comes into force.

Nothing changes overnight for users. A firm already on the register can keep trading while the FCA reviews its file. The gateway is the paperwork stage, not the finish line.

Which firms and activities are covered

The regime reaches across the crypto business, not one corner of it. The FCA listed five regulated activities: issuing qualifying stablecoins, running a trading platform, dealing and arranging deals, safeguarding customer assets, and arranging staking. The rules cover firms that offer these services to UK customers. A firm has to work out which activities it does, then apply for each one.

This is a big step up from the old rules. Before now, a crypto firm in the UK only had to register for anti-money laundering checks. The new regime adds a full rulebook. Firms must hold capital, pass stress tests, and follow the Consumer Duty that already binds banks and brokers. Trading platforms also face rules against insider dealing and market manipulation, drawn from mainstream finance.

Stablecoins get their own treatment. The FCA set what it called clear and transparent standards for the firms that issue them, with simpler capital rules than some other activities carry. The point, the regulator said, is to build trust in tokens that are meant to hold a steady value. That matters because stablecoins now move a large share of crypto trading volume.

What happens to firms that miss the window

Timing carries real weight here. Firms that apply inside the window but are not cleared by 25 October 2027 get a saving provision, which lets them keep working until their case is decided, the FCA said. Miss the February deadline and the terms get harder. That is the catch.

Late applicants fall into a statutory transitional provision. Under it, a firm can only finish contracts it signed before the cut-off. It cannot take on new UK customers. It cannot sell new products to the ones it already has.

Firms that do not apply at all face the bluntest outcome. They must wind down their UK crypto business before the regime starts, with no protection to fall back on. FinanceFeeds, reporting on the rules, called the gap between early and late filers the difference between a managed review and a forced run-off.

How the UK compares

Britain is arriving late to crypto regulation at this scale. The European Union's MiCA framework is already in force across the bloc, and Brussels began licensing crypto firms well before London opened its gateway. UK officials argue the wait bought them a more complete rulebook.

David Geale, the FCA's Executive Director of Consumers, Payments and Competition, framed it as a trade worth making. "We are building a crypto regime that firms, consumers and international partners can trust," he said. The pitch is stability over speed.

What to watch

Watch two things through 2027. How many firms clear the gateway before the October start date, and how many quietly leave the UK rather than meet the capital bar. The FCA has not said how many firms on its existing register plan to apply.

One number will tell the story: how many licensed firms are still standing when the regime begins. The gateway is open. Whether the UK turns into the hub it wants to be is a 2027 question, not a 2026 one.
