Choosing a trustworthy cryptocurrency exchange is essential to safeguarding your digital assets. With the growing popularity of crypto trading in the UK, many investors are asking: Is OKX legal in the UK? And more importantly, is it safe to use? This comprehensive review explores the regulatory status, security measures, features, and overall reliability of OKX for UK-based traders.

Is OKX Regulated in the UK?
A critical factor when evaluating any crypto exchange is its regulatory standing. In the UK, cryptocurrency exchanges must comply with rules set by the Financial Conduct Authority (FCA) under the Anti-Money Laundering and Counter-Terrorist Financing (AML/CFT) regulations introduced in 2020.
To operate legally in the UK, an exchange must:
- Register with the FCA
- Implement robust KYC and AML procedures
- Maintain a local office and bank account
- Undergo regular audits
Despite its global presence, OKX does not currently hold FCA authorization. This means it is not fully regulated under UK financial law. However, this does not automatically make it illegal for UK residents to use.
Many international exchanges, including OKX, serve UK customers while operating under licenses from other jurisdictions—such as Malta’s Financial Services Authority (MFSA), which OKX holds. Additionally, OKX complies with AML/CFT standards globally and enforces strict KYC protocols.
It's important to note that while unregulated status may raise concerns, it's common among major global platforms due to varying national laws. The absence of a UK license means users do not benefit from protections like those offered by the Financial Services Compensation Scheme (FSCS).
Security Measures: How Safe Is OKX?

Tax Implications for UK Traders Using OKX
In the UK, cryptocurrencies are treated as assets, not currency. This means any profit from trading is subject to Capital Gains Tax (CGT).
As of 2025:
- The annual tax-free allowance is £6,000
- Gains above this threshold are taxed at either 10% (basic rate) or 20% (higher rate) depending on income
Traders using OKX must keep accurate records of all transactions—including buys, sells, swaps, and disposals—for self-assessment reporting to HMRC.
💡 Tip: Use crypto tax software to automatically sync with OKX via API and generate compliant tax reports.
Frequently Asked Questions (FAQ)
Can I legally use OKX if I live in the UK?
Yes. While OKX is not FCA-regulated, there is no law prohibiting UK residents from using international crypto exchanges. You remain responsible for complying with tax and reporting obligations.
Does OKX support GBP deposits?
No. OKX does not currently offer direct fiat on-ramps for British pounds. Users typically buy USDT or BTC via third-party payment providers and transfer them to their OKX wallet.
How does OKX compare to UK-regulated exchanges?
