Crypto in the UK: Rules, Tax and Exchanges
Updated 7 October 2026
Crypto in the UK is regulated at two main points: firms that want to offer crypto services to UK customers must be authorised or registered with the Financial Conduct Authority (FCA), and the way crypto is promoted to UK consumers is subject to the FCA's financial promotions rules. For tax, HM Revenue & Customs (HMRC) generally treats cryptoassets as property, so disposals can fall within Capital Gains Tax rather than being taxed as income.
This page covers the rules that matter most to UK readers, how tax usually works, and the practical steps people take to buy Bitcoin here.
FCA crypto regulation in the UK
The FCA is the main financial regulator in the UK. Its approach to crypto has two strands that matter to ordinary users.
First, firms carrying out certain crypto activities in the UK must be registered with the FCA under the money laundering regulations. This covers cryptoasset businesses such as exchanges and custodian wallet providers. Registration is not the same as full authorisation, and it does not mean the FCA has approved a product as safe.
Second, the FCA's financial promotions regime applies to how crypto is marketed to UK consumers. Firms promoting crypto to UK customers generally need to be authorised by the FCA, or have their promotions approved by an authorised firm, unless an exemption applies. The rules also introduced categories such as restricted, high net worth and certified sophisticated investors, along with cooling-off periods for first-time investors in some cases.
The practical effect is that UK users should expect more friction when signing up, more risk warnings, and fewer promotions that make crypto look like a guaranteed return. If a platform is targeting UK customers without meeting these requirements, that is a warning sign.
You can check the FCA's own guidance and its register of firms directly. Always verify a firm's status on the FCA website rather than relying on a badge or claim on a platform's homepage.
Crypto tax in the UK: the basics
HMRC does not treat crypto as currency. It treats cryptoassets as property, which means disposals can trigger Capital Gains Tax (CGT).
A disposal is broader than selling for pounds. It can include:
- selling crypto for fiat money such as GBP
- swapping one cryptoasset for another
- using crypto to pay for goods or services
- gifting crypto to someone who is not your spouse or civil partner
You generally need to work out a gain or loss for each disposal, based on the difference between what you paid and what you received. HMRC has published guidance on how to calculate this, including pooling rules for assets of the same type.
There is an annual CGT allowance, and there are different rates depending on your overall income and the type of asset. These figures change, so check the current rates and allowance on GOV.UK rather than relying on older numbers.
If you are trading crypto actively, or receiving it as payment for work, income tax and National Insurance may apply instead of, or as well as, CGT. Record keeping matters: HMRC expects you to keep details of each transaction, including dates, amounts, values in GBP and any fees.
How to buy Bitcoin in the UK
Most UK buyers follow a similar path:
- Choose a platform that is registered with the FCA or otherwise compliant with UK promotion rules.
- Complete identity checks, which are required under UK anti-money laundering rules.
- Deposit GBP by bank transfer or card, depending on the platform.
- Place a buy order for Bitcoin, either at market price or with a limit order.
- Decide whether to leave the Bitcoin on the exchange or move it to a wallet you control.

What to check before picking an exchange
There is no single best crypto exchange in the UK for everyone. The right choice depends on how you plan to use it. Before you sign up, check:
| Check | Why it matters |
|---|---|
| FCA registration status | Confirms the firm has met UK anti-money laundering requirements for crypto activities |
| Fee structure | Spreads, trading fees and withdrawal fees vary widely and affect returns |
| Deposit and withdrawal methods | GBP bank transfers are usually cheaper than card payments |
| Custody options | Some platforms let you withdraw to your own wallet, others do not |
| Customer support | Useful if a withdrawal or verification issue arises |
| Security history | Look for public information on past incidents and how they were handled |

FAQs
Is crypto legal in the UK?
Yes, owning and trading crypto is legal in the UK. The rules focus on how firms operate and how crypto is promoted, rather than banning personal ownership.
Do I pay tax if I only buy and hold crypto?
Buying and holding usually does not trigger a tax charge by itself. Tax generally applies when you dispose of crypto, which includes selling, swapping or spending it.
Do I need to report crypto on my tax return?
If your gains exceed the annual allowance, or if HMRC has asked you to report, you usually need to declare them. Check the current rules on GOV.UK.
Where can I verify a UK crypto firm?
Use the FCA register and the FCA's own crypto guidance pages. For tax questions, use HMRC's published cryptoassets guidance on GOV.UK.
