The UK continues to push forward with its ambition to become a global leader in cryptocurrency innovation. Despite evolving challenges and regulatory scrutiny, the government remains committed to fostering a supportive environment for blockchain and digital asset development. This article explores the current state of crypto regulation in the UK, breaks down key compliance requirements, and highlights what businesses need to know to operate within this dynamic landscape.
Is Cryptocurrency Regulated in the UK?
As of now, cryptocurrencies in the UK are not universally regulated. Instead, regulation applies on a case-by-case basis depending on the nature and characteristics of the specific digital asset. The Financial Conduct Authority (FCA), in collaboration with the Bank of England and HM Treasury, established a Cryptoassets Taskforce to develop a classification framework that determines whether a cryptoasset falls under existing financial regulations.
The taskforce identified three primary categories:
- Security tokens – These represent investments such as debt or equity in a company and are treated as financial instruments. As such, they fall under FCA regulation.
- Exchange tokens – Examples include Bitcoin and Ethereum, which are primarily used as means of exchange. These are currently not regulated as securities.
- Utility tokens – Provide access to a product or service within a specific platform. Generally unregulated unless they exhibit features of a security.
Additionally, any cryptoasset that qualifies as electronic money (e-money) is subject to regulation under e-money rules.

This means that regulatory oversight kicks in only when a cryptoasset’s design and function align with existing regulated financial products — for example, if it offers returns, dividends, or voting rights akin to traditional securities.
It’s also important to note that an asset's regulatory status can change over time. A token initially classified as a utility may evolve into a security if new functionalities are introduced, thereby triggering compliance obligations.
Anti-Money Laundering (AML) Regulations for Crypto Firms
Even if a cryptoasset itself isn't regulated, businesses involved in crypto-related services may still be subject to strict regulatory requirements — particularly under anti-money laundering laws.
Under the Money Laundering, Terrorist Financing and Transfer of Funds (Information on the Payer) Regulations 2019, which implemented the EU’s Fifth Anti-Money Laundering Directive (AMLD5), two types of crypto businesses must register with the FCA:
- Cryptoasset exchange providers – Platforms that allow users to trade fiat currency for crypto or vice versa.
- Cryptoasset custodian wallet providers – Firms offering storage solutions for digital assets on behalf of clients.
These entities must comply with full AML obligations, including:
- Conducting customer due diligence (CDD)
- Monitoring transactions for suspicious activity
- Appointing a Money Laundering Reporting Officer (MLRO)
- Maintaining detailed records
- Reporting suspicious activities to the National Crime Agency
Failure to register or comply can result in enforcement action, fines, or criminal prosecution.
To determine whether a business falls within scope, two key factors are considered:
- Whether the digital asset meets the legal definition of a "cryptoasset" — defined as “a cryptographically secured digital representation of value or contractual rights using distributed ledger technology.”
- Whether the firm performs exchange or custodial functions.
Thus, even projects built around unregulated tokens like Bitcoin or Ethereum must adhere to AML rules if they operate exchanges or custody services.
Regulatory Status of Specific Crypto Assets
Bitcoin and Ethereum
Both Bitcoin and Ethereum are classified as exchange tokens and are not inherently regulated. However, any UK-based business facilitating trading or custody of these assets must comply with AML regulations and register with the FCA.
Non-Fungible Tokens (NFTs)
The regulatory treatment of NFTs depends heavily on their functionality. If an NFT represents mere ownership of digital art or collectibles, it typically remains outside regulatory scope. However, if it confers investment rights — such as profit-sharing or governance power — it may be deemed a security token and thus fall under FCA supervision.
Similarly, NFT marketplaces offering exchange services may be required to register under AML regulations.
Stablecoins
Stablecoins are receiving increasing attention from UK regulators. While currently unregulated, the proposed Financial Services and Markets Act aims to bring certain stablecoins into the regulatory fold — particularly those intended for use as a payment method.
Under this framework:
- Issuers of payment-focused stablecoins will need to seek FCA authorization.
- Requirements around reserve backing, transparency, and consumer protection will be enforced.
- Systemic risks associated with large-scale stablecoin adoption will be monitored.
This marks a significant step toward creating a tailored regulatory regime for digital currencies in the UK.
Other Legal Considerations for Crypto Businesses
Beyond financial regulation and AML compliance, companies must also consider:
- Data protection laws – Compliance with GDPR when handling user data.
- Intellectual property rights – Ensuring proper ownership and licensing of software, branding, and content.
- Consumer advertising standards – All marketing materials must be clear, fair, and not misleading, adhering to FCA and Advertising Standards Authority (ASA) guidelines.

Given the complexity and overlap of these legal domains, seeking expert legal advice early in the development process is strongly recommended.
Frequently Asked Questions (FAQ)
Q: Are all cryptocurrencies illegal in the UK?
No. Cryptocurrencies are not illegal. While most are unregulated, they are legal to buy, sell, and use. Regulatory obligations apply based on how the asset is structured and used.
Q: Do I need FCA approval to launch a cryptocurrency in the UK?
Only if your token qualifies as a security or e-money. Otherwise, general issuance does not require approval — but related services (like exchanges) may require FCA registration under AML rules.
Q: Can I run a crypto exchange from the UK without registering?
No. Any business facilitating the exchange between crypto and fiat currencies must register with the FCA under AML regulations.
Q: How does the UK government support crypto innovation?
Through initiatives like regulatory sandboxes, engagement with industry stakeholders, and proposed legislation to regulate stablecoins — all aimed at making the UK a safe and attractive hub for blockchain innovation.
Q: What happens if my token changes from utility to security?
You must reassess its classification and potentially notify the FCA. Operating without proper authorization after crossing into regulated territory can lead to penalties.
Q: Is DeFi regulated in the UK?
Not directly yet. However, if a DeFi platform performs functions equivalent to regulated activities (e.g., lending, exchanging), it may fall under existing rules. Regulators are actively assessing how to approach decentralized finance.

Final Thoughts
The UK’s approach to crypto regulation balances innovation with consumer protection and financial stability. While comprehensive legislation is still developing, clear frameworks exist for AML compliance and security-like tokens. With plans to regulate stablecoins and ongoing dialogue between regulators and industry players, the path toward becoming a global crypto hub is well underway.
For businesses looking to enter or expand in the UK market, understanding the nuances of asset classification and regulatory obligations is essential. Staying compliant isn’t just about avoiding penalties — it’s about building trust in an emerging financial ecosystem.
