UK Crypto Regulation: Who Regulates What?
Crypto regulation in the UK is changing. Learn how UK crypto regulation works, who oversees what, and what to check before investing.
Crypto regulation in the UK is changing. For years, oversight focused mainly on anti-money laundering rules and how crypto companies marketed their services. Now, the UK is preparing to bring a much wider range of crypto activities under financial regulation.
The Financial Conduct Authority (FCA) is at the centre of that shift, but it isn't the only organisation involved. HM Treasury sets the legislative framework, the Bank of England and Prudential Regulation Authority (PRA) have roles in the wider financial system, and the Financial Services Compensation Scheme (FSCS) determines whether certain customers can claim compensation when a financial firm fails.
For investors, the tricky part is understanding what these rules actually mean. A crypto exchange can be registered with the FCA without being fully authorised to provide regulated financial services. And even when a company is regulated, that doesn't mean your Bitcoin or Ethereum is protected if its price crashes or the platform goes bust.
Here's how UK crypto regulation works, who oversees what, and what to check before choosing a crypto exchange.
Is crypto legal in the UK?
Yes, buying, selling, and holding cryptocurrency is legal in the UK.
However, not every crypto-related activity is treated the same way under UK law. Some activities fall within existing financial services rules, while others are subject to specific requirements covering anti-money laundering, advertising, taxation or other areas.
For example, crypto exchanges that provide certain services in the UK must comply with applicable anti-money laundering requirements. Businesses marketing crypto to UK consumers must also follow the financial promotions regime.
Crypto isn't legal tender in the UK, either. Businesses aren't generally required to accept it as payment, and owning cryptocurrency doesn't give you the same protections as holding money in a bank account.
The bottom line is that you can legally own and trade crypto, but the services you use and the activities you carry out may be subject to different rules.
Is crypto regulated in the UK?
Yes, but the extent of regulation depends on the cryptoasset and the activity involved.
Historically, most direct investments in unregulated cryptoassets, such as Bitcoin and Ether, sat outside the FCA's traditional financial services regulatory scope. Nonetheless, the FCA had responsibilities covering anti-money laundering registration for certain crypto businesses and the promotion of cryptoassets to UK consumers.
All that’s changing now, though.
The Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026 establishes a framework for cryptoasset regulation. The FCA has published its final rules, and the new regime is scheduled to take effect on 25 October 2027.
Under the new framework, more activities will require FCA authorisation, including operating cryptoasset trading platforms, safeguarding cryptoassets for customers, and certain dealing, arranging and staking services.
The FCA opened its application gateway for firms on 30 September 2026. Firms planning to undertake the new regulated activities need to prepare for the change, with the application window for firms seeking to use the transitional arrangements running until 28 February 2027.
This doesn't mean every cryptocurrency will suddenly become a regulated investment. The new regime focuses on defined activities and services, and the rules that apply will depend on the nature of the cryptoasset and what a firm does with it.
Is crypto asset trading regulated in the UK?
It depends on the type of trading and the services involved.
Buying and selling a cryptocurrency such as Bitcoin on a spot exchange has historically been treated differently from trading a traditional financial instrument. Direct investments in many unregulated cryptoassets haven't carried the same protections as regulated investments such as shares or certain derivatives.
That said, several rules already apply to crypto trading services.
Anti-money laundering: Certain cryptoasset exchange providers and custodian wallet providers must register with the FCA under the Money Laundering Regulations.
Financial promotions: Cryptoasset promotions to UK consumers must comply with the relevant UK rules, including requirements around risk warnings and how promotions are communicated.
Regulated financial products: Products such as certain crypto derivatives and security tokens may already fall within existing financial services regulation.
The new regime will bring more crypto trading services within the FCA's remit, with rules covering areas such as market integrity, financial resilience and consumer protection.
Who regulates crypto in the UK?
Several organisations have roles in the UK's crypto regulatory framework. The FCA is the main financial regulator for crypto businesses, but its responsibilities differ from those of HM Treasury, the PRA, HMRC and other bodies.
Financial Conduct Authority (FCA)
The FCA is the main regulator most crypto investors know.
Its current responsibilities include registering eligible cryptoasset businesses under the Money Laundering Regulations, supervising their compliance with those requirements, and overseeing the UK's financial promotions regime for cryptoassets.
The FCA also regulates certain crypto-related financial products and services that already fall within its existing remit.
From 25 October 2027, the new cryptoasset regime will expand its role significantly. Firms undertaking the new regulated activities will generally need FCA authorisation, subject to applicable exemptions and transitional provisions.
The FCA also maintains the Financial Services Register, where consumers can check a firm's status and the permissions it holds.
HM Treasury
HM Treasury is responsible for developing the government's financial services policy and legislative framework.
It plays a central role in deciding how crypto regulation is structured, including introducing legislation that brings additional cryptoasset activities within the regulatory perimeter.
The FCA then develops and applies the relevant regulatory rules within its statutory remit.
In simple terms, HM Treasury helps establish the legal framework, while the FCA supervises firms and enforces the rules that apply to them.
Bank of England and Prudential Regulation Authority (PRA)
The Bank of England is responsible for monetary and financial stability, while the PRA, which is part of the Bank of England, supervises the safety and soundness of banks, insurers and certain other financial institutions.
Their involvement in crypto depends on the activity and the type of firm involved. For example, stablecoins and crypto-related services that interact with the wider financial system can raise questions about payment systems, financial stability and the supervision of firms that are already subject to prudential regulation.
The FCA is the primary point of reference for most retail crypto exchange users, but it isn't the only regulator with responsibilities that can touch the crypto sector.
HM Revenue & Customs (HMRC)
HMRC deals with UK crypto taxes.
For individuals, selling or trading crypto may trigger capital gains tax, while activities such as staking rewards may have income tax implications depending on the circumstances.
HMRC also has responsibilities relating to information reporting and tax compliance. It doesn't regulate crypto exchanges in the same way as the FCA, but its role is important if you're buying, selling or earning crypto.

Information Commissioner's Office (ICO)
The ICO regulates data protection and information rights in the UK.
Crypto businesses that process personal information must comply with applicable data protection legislation. That can include requirements around how they collect, store, use, and share customer information.
The ICO isn't a financial regulator, but its remit can apply to crypto exchanges, wallet providers and other businesses handling personal data.
Are crypto assets protected by FCA?
Not automatically. The FCA's involvement in regulating a company doesn't mean the cryptoassets you buy through it are protected against losses.
In fact, most direct investments in unregulated cryptoassets haven't benefited from the same FCA protections that apply to traditional regulated investments. The FCA has repeatedly warned consumers that cryptoassets are high-risk and that they should be prepared to lose all the money they invest.
The new cryptoasset regime is intended to introduce stronger standards for firms carrying out regulated crypto activities, including requirements covering consumer protection, safeguarding, financial resilience and market integrity.
However, regulation of the business and protection of the asset are two different things. An authorised crypto firm won't be able to guarantee that Bitcoin's price won't fall, that a token won't fail, or that every customer will recover their assets if something goes wrong.
It's also important to understand what kind of FCA status a company holds.
A firm registered under the Money Laundering Regulations has met the requirements for that registration. It hasn't automatically received full FCA authorisation for all its services, and that registration doesn't mean its crypto products are endorsed by the FCA.
Likewise, a company may be authorised for one financial activity but not another. You should check the specific permissions and services covered by its regulatory status.
Are crypto assets protected by FSCS?
Generally, no. Direct holdings of cryptocurrencies such as Bitcoin and Ethereum aren't protected by the Financial Services Compensation Scheme (FSCS).
The FSCS provides compensation to eligible customers when an authorised financial firm fails, and the relevant legal and eligibility requirements are met. Protection depends on the product, the activity, the firm's status and the circumstances of the claim.
It doesn't cover investment losses simply because an asset has fallen in value. And it doesn't generally compensate investors for losses on direct holdings of unregulated cryptoassets.
For example, if you buy Bitcoin and its price drops by 50%, you can't claim FSCS compensation for the loss. If a crypto exchange fails and you can't recover your coins, you shouldn't assume the FSCS will reimburse you.
There may be different considerations where a crypto-related product is itself a regulated financial product or where a firm provides another service that falls within the FSCS's scope. Eligibility depends on the precise circumstances.
It's also worth distinguishing crypto held on an exchange from eligible cash deposits held with a bank. Any protection for cash depends on the account, the legal entity holding the funds, and the applicable deposit protection rules. It doesn't mean the cryptocurrency itself is protected.
Before depositing money or buying crypto, check the provider's terms and its disclosures about the protections that do and don't apply.
Why should you only use FCA-registered crypto businesses?
Choosing a crypto exchange with the appropriate FCA status is an important first step, but it's worth understanding exactly what you're checking.
Under the current regime, certain cryptoasset businesses must register with the FCA under the Money Laundering Regulations before providing in-scope services in the UK. Registration involves anti-money laundering and counter-terrorist financing requirements.
That can help reduce the risk of dealing with an entirely unaccountable operator. It also gives you an official source for checking whether a firm has the registration it claims to hold.
But FCA registration is not the same as full FCA authorisation, and it isn't an endorsement of a crypto exchange or its products.
Don't rely on a logo, a marketing claim or a statement that an exchange is "FCA approved". Look up the legal entity yourself and check its current status, the services it is permitted to provide and any restrictions.
It's also sensible to consider security, fees, withdrawal policies, custody arrangements and the exchange's track record. Regulatory status is important, but it isn't the only factor when deciding where to trade.
Which crypto exchanges are regulated in the UK?
This is where the terminology gets confusing. Crypto exchanges may describe themselves as FCA registered, FCA regulated or FCA authorised, but those terms aren't interchangeable.
At present, some cryptoasset businesses are registered with the FCA under the Money Laundering Regulations. This registration covers relevant anti-money laundering obligations; it doesn't mean that the exchange is fully authorised under the new cryptoasset regime.
The new regime is scheduled to begin on 25 October 2027. Firms that intend to carry out the newly regulated activities will generally need to obtain the appropriate FCA authorisation, unless an exemption or transitional arrangement applies. As the authorisation process is now open, an exchange's regulatory position may change over time.

How to check a cryptocurrency exchange licence in the UK?
The UK doesn't operate a single, universal crypto exchange licence that automatically covers every service a platform offers. Instead, the regulatory requirements depend on the services provided and the legal framework that applies.
To check for an FCA licence:
Open the FCA Financial Services Register. Search for the company's legal name, not just its trading brand.
Check its registration or authorisation status. Confirm whether it is registered under the Money Laundering Regulations, authorised under the Financial Services and Markets Act, or holds another type of permission.
Read the scope of its permissions. Don't assume that authorisation for one service covers every crypto product or activity offered by the wider group.
Verify the website and contact details. Make sure the website you're using matches the details on the register. Watch out for clone firms impersonating legitimate companies.
Check for warnings and restrictions. Search the FCA's warnings and review any restrictions or limitations that apply to the entity.
