- The FCA joined HMRC and the Metropolitan Police in action at three London peer-to-peer crypto trading locations.
- The FCA said there are currently no FCA-registered peer-to-peer crypto businesses operating in the U.K.
- Britain’s crypto framework takes full effect on Oct. 25 2027 and applications open from Sept. 30 to Feb. 28 2027.
UK crypto enforcement moved into sharper focus after Britain’s Financial Conduct Authority said it acted against three illegal peer-to-peer crypto trading locations in London. The operation was carried out with HM Revenue & Customs and the Metropolitan Police, and the regulator said traders at the sites were told to stop operating illegal crypto businesses. The action came as the U.K. moves closer to implementing its wider crypto framework, with recent FCA guidance outlining which activities fall within the incoming regime. Taken together, the enforcement step and the guidance suggest closer scrutiny for firms that operate in areas requiring registration or approval.
UK crypto enforcement in London
The FCA said Thursday that it conducted actions at three London premises used for illegal peer-to-peer crypto trading. According to the regulator, the crackdown was a joint effort with HMRC and London’s Metropolitan Police. It said cease-and-desist letters were issued at the sites, requiring traders to stop taking part in illegal crypto businesses.
The agency described peer-to-peer trading as a process in which individuals buy and sell crypto directly with each other. In the U.K., that activity needs to be legally registered. The FCA also said there are currently no FCA-registered peer-to-peer crypto businesses operating in the country.
Why the FCA took action
The FCA said operators outside its registration regime avoid controls intended to detect and prevent money laundering. That point formed a central part of the regulator’s explanation for the action in London. By emphasizing the lack of registered peer-to-peer operators, the watchdog underscored that such businesses are expected to fall within its oversight.
Caroline Black, a consultant at Gherson Solicitors LLP, said the move showed that the period of “light-touch” crypto regulation in the U.K. is ending. She said this was the second coordinated enforcement operation in six months and that it confirmed a shift from warnings to active disruption of unregistered P2P crypto businesses, with criminal liability a live risk for operators trading by way of business without proper registration.
UK crypto enforcement and the 2027 framework
The latest UK crypto enforcement push comes as Britain’s broader cryptocurrency framework moves toward implementation. The framework will come fully into force on Oct. 25, 2027. Before that, firms may apply for FCA approval during a window that starts on Sept. 30 and runs through Feb. 28, 2027.
Earlier in the week, the FCA issued guidance clarifying how the regulatory perimeter of the incoming cryptoasset regime will apply. Aditya Mittal, managing principal at Capco, said firms should prioritize understanding which parts of their business fall within scope after that guidance.
Guidance for firms under the incoming regime
The FCA guidance covers issuing qualifying stablecoins, operating crypto exchanges, dealing and coordinating deals, safeguarding digital assets and staking. It also set out the activities that need FCA approval. That gives firms more detail on where the regulator draws the line as the full regime approaches.
The combination of detailed guidance and enforcement activity marks a notable moment for the sector in Britain. Firms now have both a clearer outline of the activities covered by the incoming regime and a visible example of how the authorities are responding to businesses that operate outside the required registration framework.
Conclusion
UK crypto enforcement is becoming more visible as the FCA combines new guidance with joint action against unregistered activity. In London, the regulator worked with HMRC and the Metropolitan Police to order traders at three peer-to-peer crypto locations to stop operating illegal businesses. The FCA said no peer-to-peer crypto businesses are currently registered in the U.K., and it linked activity outside its regime to the avoidance of money laundering controls. With the application window set for Sept. 30 through Feb. 28, 2027, and the wider framework taking effect on Oct. 25, 2027, firms now face a clearer timetable and stronger signals about regulatory expectations.
