UK crypto regulation: what changes in October 2027

The United Kingdom created a broader cryptoasset regulatory framework in 2026, but the main new authorisation regime is not yet fully in force. HM Treasury says the Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026 will take effect in October 2027.

That timing matters. A company saying it is “registered in the UK” today should not automatically be described as already authorised under the future regime.

What the 2026 Regulations establish

The Regulations bring specified cryptoasset activities into the UK's regulated-activities framework. When the relevant provisions commence, firms carrying on those activities will generally need authorisation from the Financial Conduct Authority (FCA), unless an exclusion or another applicable status applies.

HM Treasury's April 2026 policy note says the framework was made in February 2026 and comes into force in October 2027. The government also proposed amendments dealing with stablecoin payment services and other technical issues. Proposed amendments should be distinguished from rules that have completed the legislative process.

Registration, promotions and future authorisation are different

Before the broader regime begins, several existing obligations remain relevant. Certain UK cryptoasset businesses are subject to FCA registration for anti-money-laundering and counter-terrorist-financing supervision. Cryptoasset financial promotions are also subject to specific rules.

AML registration is not the same as a full assessment of every product, custody arrangement or investment risk. Likewise, compliance with financial-promotion rules does not guarantee that a token or platform is safe.

What users should verify

  • Find the exact legal entity named in the platform's terms.
  • Check the live FCA register and any FCA warning-list entry.
  • Read which activity and legal status the record actually covers.
  • Do not rely on a logo, a group brand or the phrase “UK registered” without checking its meaning.
  • Recheck the commencement timetable before relying on a 2027 claim.

Risk remains

Regulation can improve standards and supervision, but it does not eliminate fraud, insolvency, cyberattack, custody failure, liquidity problems or market loss. The framework and implementation details may also change before October 2027.
