How Do Mortgage Lenders Treat Cryptocurrency Deposits?
In the UK, lenders are generally cautious when it comes to accepting cryptocurrency and crypto assets to support a mortgage loan. As the relationship between cryptocurrency and mortgages continues to evolve, lenders are becoming more open to accepting crypto-derived funds for deposits, but they typically require the assets to be converted into pounds and supported by thorough documentation.
The main concern for lenders is that digital currency is often volatile and difficult to trace. However, by providing clear documentation of conversions from crypto to fiat currency, it is possible to meet lenders’ requirements.
Ultimately, lenders need to ensure that the funds used or declared on your mortgage application are legally obtained, traceable, and stable. As such, for lenders to even consider cryptocurrency in your mortgage application, you will need to be able to:
- Provide clear proof of the origin of your crypto, including full wallet transaction history and exchange activity.
- Documented evidence that the crypto was legally acquired and fully converted into GBP.
- Demonstrate stable, long-term holdings – lenders often prefer this over short-term speculative trades as it indicates a more secure financial position.
In short: If you’re planning to submit a deposit that is made up of assets cashed out from a crypto wallet, you’ll need to ensure that you can demonstrate a consistent history of those holdings. Any attempt to use untracked peer-to-peer transfers will almost certainly be rejected.

What Proof Do I Need to Use Cryptocurrency for a Mortgage Deposit?
When applying for a mortgage with cryptocurrency, proving the legitimacy and source of your deposit is key. In the UK, cryptocurrency is not legal tender. As such, lenders will require any cryptocurrency to be transferred into GBP.
To ensure financial protection, lenders will also focus on anti-money laundering (AML) compliance. As a result, all supporting documents that prove the legitimacy of your currency will need to be thorough, clear, and consistent. Here’s what most lenders will typically ask for:
- Wallet transaction history that shows how and when you acquired the crypto.
- Exchange records confirming the sale or conversion of the cryptocurrency into GBP.
- Bank statements showing the funds arriving in your UK account.
- Tax documentation to confirm compliance with HMRC and the appropriate declaration of gains, including declaring cryptocurrency gains for mortgage affordability assessments.
Here we have provided a quick overview of the most common documentation that lenders will expect to see:
Type of Document | Purpose | Is It Mandatory? |
Wallet transaction history | Proves ownership and duration of crypto holdings | Yes |
Exchange statements | Shows legal conversion to GBP | Yes |
UK bank statements | Verifies receipt of cleared fiat funds | Yes |
Crypto tax documents (e.g. SA100) | Confirms compliance with HMRC regulations | Often |
Identity & AML checks | Required by lender for anti-money laundering compliance | Yes |
Written declaration (if requested) | May be requested for irregular deposits or large transfers | Case-by-case |
When it comes to cryptocurrency and lenders – it’s all about evidence. Lenders will have strict strict guidelines, and even small gaps in your financial trail can lead to unnecessary delays or rejections. As such, without this level of documentation, it can be difficult for lenders to approve your cryptocurrency mortgage deposit.
At Boon Brokers, our dedicated mortgage experts have a wealth of experience dealing with the complexities of cryptocurrency and mortgages. With whole-of-market access, we can help match your unique situation to lenders who are open to crypto deposits – securing you the best mortgage deal that aligns with your needs.
Can I Pay a House Deposit Directly in Cryptocurrency?
No, you cannot pay mortgage deposits directly in cryptocurrency. In the UK, cryptocurrency is not legal tender. As such, mortgage lenders, solicitors, and estate agents will almost exclusively deal in GBP.
While the idea of sending your earned Bitcoin straight to a lender’s or estate agent’s wallet might sound simple, the reality is that the financial market operates within a strict regulatory framework designed to minimise financial crime. Unfortunately, because cryptocurrency users often remain anonymous, it is very difficult for lenders to trace transactions, which raises red flags for compliance.
Even in the scenario that both buyer and seller agree to a crypto transaction, it remains highly unlikely that any UK lender or solicitor would participate or approve the deal. Simply, mortgages that are funded by crypto must go through a full conversion into legal tender, AML checks, and documented transactions.
Do All UK Lenders Accept Cryptocurrency as a Deposit Source?
No, most UK lenders do not accept cryptocurrency directly as a deposit source. The majority of high street banks are still cautious about crypto, with many choosing to reject it entirely due to risk and regulation concerns.
As we’ve already touched on, lenders are cautious due to the risks and complexities of verifying crypto funds, as well as the volatility of cryptocurrency values; the value of cryptocurrency can change quickly and drastically. It’s important for lenders to see a clear, traceable path of the money – from pounds to crypto and back again – before agreeing to a mortgage offer.
The table below outlines the key requirements and explains why each is important in the approval process.
Requirement | What Lenders Expect | Why It Matters |
Proof of purchase | An audit trail showing how the pounds were originally used to buy the cryptocurrency | Ensures the funds were legally acquired |
Conversion to pounds | The deposit must be submitted as legal tender and so needs to be converted back to GBP before the mortgage offer is finalised | Protects against crypto volatility and confirms an exact deposit value |
AML compliance | Applications must pass Anti-Money Laundering (AML) checks to confirm the legitimacy of the funds | Prevents money laundering and financial crime in the mortgage process |
Solicitor approval | Your solicitor must be comfortable with the source and documentation of the deposit | Ensures legal compliance and smooth completion of the property sale |
An increasing number of leading high-street lenders, such as Halifax and Barclays, are now open to mortgage applications backed by cryptocurrency, while specialist lenders often offer more flexible criteria.
If you plan to use cryptocurrency as part of your deposit, speaking to a trusted mortgage broker early can help you save both time and money.

Book a Free CallIs Crypto Volatility a Problem for Mortgage Applications?
Yes, the high volatile nature of cryptocurrency is one of the biggest problems in mortgage applications. As a digital asset that can fluctuate drastically in value overnight, crypto is still considered an unreliable source or proof of income by most lenders.
When completing a crypto mortgage application, lenders will require you to convert crypto to GBP well in advance of your mortgage application.
Additionally, it’s best to keep your funds in one place. Frequent transfers between wallets or exchanges might appear suspicious to lenders and trigger extra checks, slowing down your application and eligibility.
How Should I Prepare If I Plan to Use Crypto for a Mortgage?
Lenders will expect a clear financial trail and evidence of stable funds. And so, if you’re planning to use digital assets to fund a mortgage, preparation is everything.
Your strategy to provide evidence needs to be proactive. Here are 4 key steps that can help you secure a mortgage with cryptocurrency:
1. Sell Your Crypto and Convert to GBP Early
Lenders won’t accept cryptocurrency directly. You’ll need to convert your crypto into legal tender (GBP) well before applying.
While you may have the urge to wait and hope your pot increases, converting your cryptocurrency into a more stable legal tender early will protect you from market volatility and allow your funds to settle in a bank account, demonstrating to lenders that you have the financial stability to secure a mortgage.
2. Keep Detailed Records of Every Transaction
To pass anti-money laundering checks, you’ll need a clear audit trail. This includes your wallet history, exchange records, and bank transfers.
Having all the right documents and being transparent about your trading will help build more confidence with your chosen lender, demonstrating that you have a safe, legal, and reliable source of finance for your mortgage deposit.
3. Gather Your Crypto Tax Documentation
HMRC expects capital gains on crypto to be declared. Some lenders may ask for your self-assessment return (SA100) to confirm that the crypto was legally acquired and declared.
Understanding your crypto capital gains tax UK obligations and having the right documentation ready can show compliance and credibility, helping quicken the application process.

Frequently Asked Questions
What Are the Potential Risks of Using Cryptocurrency to Apply for a Mortgage?
The main risk of cryptocurrency is that its value is volatile. Its worth can change overnight, and for this reason, lenders do not typically accept cryptocurrency as a source of income or funding.
To use cryptocurrency in a mortgage application, it must first be converted into standard legal tender – GBP in the UK. Lenders will also require clear evidence of the funds’ origin and documentation outlining your transaction history. Lenders may reject deposits if the source of funds can’t be clearly verified.
Can Cryptocurrency Earnings Be Counted as Income in a Mortgage Affordability Assessment?
No, cryptocurrency can not be used in mortgage affordability assessments. In most cases, UK lenders do not accept cryptocurrency earnings as a valid source of income for affordability checks.
Even if you’ve declared crypto profits to HMRC, lenders typically prefer income from stable and verifiable sources, such as PAYE employment or self-employment earnings.
Does Owning or Trading Cryptocurrency Impact Your Credit Score?
No, currently cryptocurrency transactions do not appear on credit reports and so owning crypto will not directly affect your credit score.
Can Solicitors Handle Cryptocurrency Transactions in the Mortgage Process?
No. Most solicitors are not equipped to process direct crypto payments. As cryptocurrency is not a legal tender in the UK, the funds must be converted into GBP and held in a UK account before any exchange.
