How is crypto regulated in the UK?

Crypto sits in an unusual place in the UK’s financial rulebook. It is not regulated the same way as shares, bonds or bank accounts, and the protections most people associate with investing in those products largely do not extend to it. That gap is closing, but the process is slower and more complicated than most coverage suggests.

The Financial Conduct Authority (FCA) is the main body responsible for overseeing crypto in the UK. Its formal involvement began in January 2020, when new anti-money laundering rules required any business operating a cryptoasset exchange or providing custodial wallet services in the UK to register with the FCA. It is worth being clear about what that registration actually means, because it is widely misunderstood. The FCA was not assessing whether these firms were safe places to put your money. It was checking whether they had adequate systems in place to detect and report suspicious financial activity, including money laundering and terrorist financing. Consumer protection is a separate question entirely.

Many firms applied for registration and failed. Some withdrew their applications before the process was complete. The ones that passed can be found on the FCA’s Financial Services Register, which is publicly searchable. If you are considering using an exchange that claims to operate in the UK, checking the register first is basic due diligence. A firm that is not listed is operating either illegally or from outside UK jurisdiction in ways that leave you with very limited recourse.

The next significant shift came in October 2023, when new rules on crypto promotions came into force. From that point, any firm offering crypto to UK retail investors had to have their marketing either approved by an FCA-authorised person, communicated by one, or issued directly by a firm that was itself FCA-registered. The rules also introduced mandatory risk warnings, a 24-hour cooling-off period for people making their first investment with a given firm, and a ban on incentives such as refer-a-friend bonuses designed to encourage people to open accounts and start trading.

Several large overseas exchanges either pulled out of the UK market entirely or restricted access for UK users rather than comply. Others moved quickly to meet the new requirements. The practical consequence for anyone seeing a crypto advertisement today is that a clear FCA risk warning is legally required. If it is absent, something is wrong with either the firm or the promotion itself.

The bigger structural change is still being built. The Financial Services and Markets Act 2023 gave the government and the FCA new powers to extend financial regulation to cover cryptoassets more comprehensively. The detailed rules have been developed through a series of FCA consultation papers, with the full framework expected to cover areas including crypto trading platforms, custody of customer assets, and staking services. The direction of travel is clear: the UK wants a functioning crypto industry, but one operating under rules comparable in seriousness to those governing traditional financial markets.

One thing that has not changed, and which matters considerably for anyone holding crypto, is the absence of cover from the Financial Services Compensation Scheme. The FSCS protects UK consumers if a regulated firm fails, covering deposits up to £85,000 and investments up to £85,000 per eligible person. Crypto sits entirely outside that scheme. If a crypto exchange is hacked, becomes insolvent, or misappropriates customer funds, there is no government backstop. You become an unsecured creditor of whatever is left of the firm. The collapse of FTX in November 2022 provided an unambiguous demonstration of what this means in practice for ordinary users caught up in it.

Stablecoins occupy a slightly different position in the regulatory picture. The government has signalled that fiat-backed stablecoins used as payment instruments will eventually come under a dedicated regime with stronger requirements around reserve management and the right to redeem. The rationale is that stablecoins functioning as genuine payment mechanisms carry different systemic risks from speculative tokens and deserve a different regulatory treatment. That framework is still being finalised, but the intent is clear.

On tax, HMRC has been consistent for several years. Crypto is treated as a capital asset. Capital Gains Tax applies when you dispose of it, whether that means selling for sterling, swapping one crypto for another, or using it to buy something. Income Tax applies to mining rewards, staking income, and crypto received as payment for services. The rules themselves have not changed fundamentally, but HMRC has become considerably more active in enforcement, including requesting transaction data from exchanges and issuing letters to holders who may not have declared gains correctly.

The honest summary of where the UK stands is that it has moved well beyond the early days of no regulation at all, but has not yet arrived at the comprehensive, consumer-protective framework that applies to traditional financial products. The FCA has the powers and the mandate to build that framework, and the work is visibly underway. For anyone making decisions about crypto today, the practical reality is that registration with the FCA does not guarantee a firm is safe, that FSCS protection does not apply, that tax obligations are real regardless of how an exchange is regulated, and that the rules are still changing in ways that are likely to affect how UK investors can access certain services over the next year or two.
