Deposit Sources Lenders Accept (and Reject)

Where your deposit comes from matters just as much as how much you have. Lenders don't just want to see the money — they want to know its story. This is partly about anti-money laundering (AML) regulations, but it's also about risk. A deposit that's been carefully saved over years tells a very different story to one that appeared overnight.

The Gold Standard: Savings

If your deposit comes from personal savings built up over time, most lenders will accept it with minimal fuss. They'll typically want to see:

• Bank statements showing the gradual accumulation (usually 3-6 months)
• Evidence the savings came from legitimate income
• Statements from the account where the deposit is held

The key word here is gradual. A lump sum appearing in your account two weeks before your application raises questions, even if it's perfectly legitimate.

Gifted Deposits

Gifted deposits from family members are extremely common — particularly from parents helping first-time buyers. Most high street lenders accept these, but they'll need:

• A gifted deposit letter confirming the money is a gift, not a loan
• Confirmation the giver has no interest in the property
• ID and proof of address for the person giving the gift
• Evidence of where the gift money came from (their bank statements)

Most lenders accept gifts from immediate family: parents, grandparents, and siblings. Some extend this to aunts, uncles, and even close friends, but you'll find the pool of willing lenders shrinks. Lenders like Halifax, Nationwide, and Barclays all accept family gifts with proper documentation.

Inheritance

Money inherited from a deceased relative is generally accepted by all mainstream lenders. You'll need:

• A copy of the grant of probate or letters of administration
• Solicitor's letter confirming the inheritance
• Bank statements showing the funds arriving

If the inheritance was recent, this is usually straightforward. If you inherited money years ago and it's been sitting in savings, just make sure you can trace it back.

Sale of Another Property

If your deposit comes from equity in a property you're selling, this is one of the cleanest sources. The solicitor handling your sale will confirm the net proceeds, and lenders are very comfortable with this.

Bonus, Redundancy, or Compensation Payments

Lump sums from your employer — whether bonuses, redundancy payments, or compensation — are generally accepted. You'll need:

• A letter from your employer confirming the payment
• Bank statements showing it arriving
• Your P60 or payslip showing the payment

Sources That Need More Careful Handling

Cryptocurrency

This is where things get interesting. You've sold Bitcoin or Ethereum and want to use the proceeds as a deposit. A growing number of lenders will consider this, but it requires significantly more documentation:

• Full transaction history from the exchange (Coinbase, Binance, etc.)
• Evidence of the original purchase
• Bank statements showing the fiat currency arriving
• Tax returns showing any capital gains declared

Specialist lenders like Kensington and some building societies have been more open to crypto deposits, but expect extra scrutiny. Some mainstream lenders still refuse crypto-sourced deposits entirely.

Gambling Winnings

Legitimate gambling winnings — a big win on the horses, a lottery prize — can be used as a deposit, but lenders are cautious. You'll need:

• A letter from the gambling operator confirming the win
• Your gambling account history
• Bank statements showing the funds

Personal Loans

Using a personal loan as your deposit is almost universally rejected by mainstream lenders. The logic is simple: if you need to borrow your deposit, can you really afford the mortgage? However, some specialist lenders may consider it in specific circumstances, particularly if the loan is already well-established and being repaid comfortably.

Builder's Incentives and Cashback

Some new-build developers offer cashback or deposit contributions. Lenders are aware of these schemes and many accept them, but they'll want to know the exact arrangement. Typically, the incentive can't exceed 5% of the property value without affecting the loan-to-value calculation.

Sources That Are Almost Always Rejected

• Undocumented cash — money that can't be traced to a legitimate source
• Funds from sanctioned countries — due to international sanctions regulations
• Borrowed deposits disguised as gifts — if a lender discovers a "gift" is actually a loan, the application may be declined or even treated as fraud
• Crowdfunded deposits — money pooled from multiple unrelated individuals

The Paper Trail Is Everything

Regardless of the source, the single most important thing is a clear paper trail. Anti-money laundering regulations require lenders to verify where deposit funds originate. This isn't optional — it's the law.

If you're planning to buy in the next 6-12 months, start organising your evidence now:

1. Keep all bank statements showing the deposit building up
2. If receiving a gift, get the gifted deposit letter prepared early
3. If selling assets (crypto, shares, property), keep full transaction records
4. If you've received inheritance, keep all probate documentation

What If Your Source Is Complicated?

If your deposit comes from an unusual source — or a combination of sources — a specialist mortgage broker is invaluable. They know which lenders are flexible about deposit origins and can present your case in the best light. The difference between a declined application and an approved one often comes down to knowing which lender to approach.

Don't assume your deposit source is a problem until you've spoken to someone who understands the full market. Many people with perfectly legitimate deposits get anxious because their situation doesn't fit the "normal" mould. More often than not, there's a lender who'll work with you.

Worked Example: Mixed Deposit Sources

Let's walk through a realistic scenario. Sarah wants to buy a £275,000 property and needs a 10% deposit of £27,500. Her deposit comes from three sources:

• Personal savings: £12,000 (accumulated over 3 years)
• Gift from parents: £10,000
• Sale of shares: £5,500

Sarah needs to provide:

1. Three to six months of bank statements showing her savings growing gradually
2. A gifted deposit letter from her parents, plus their bank statements showing the source of the £10,000
3. Her share dealing account statements showing the original purchase and sale of the shares, plus a bank statement showing the £5,500 arriving in her current account
4. Her capital gains tax records if the share sale triggered a taxable gain

This is a perfectly manageable situation for most high street lenders, but Sarah needs to have all the documentation ready before she applies. A missing document can delay or even derail an application.

Lender-Specific Deposit Policies

Different lenders have different appetites for various deposit sources. Here is a general guide based on publicly known lending criteria:

High Street Lenders (Most Flexible on Standard Sources)

• Halifax: Accepts savings, family gifts (parents, grandparents, siblings), inheritance, and property sale proceeds. Gifts from non-family members are not usually accepted.
• Nationwide: Similar to Halifax, but known for being slightly more flexible on the definition of "family" for gifted deposits.
• Barclays: Accept most standard sources. Have historically been pragmatic about bonus and redundancy payments with proper documentation.
• NatWest: Accept standard sources. Require gifted deposit letters to be on a specific template they provide.
• HSBC: Broad acceptance of standard sources. Their international presence can help when deposit funds originate overseas.

Building Societies (Often More Flexible)

• Leeds Building Society: Known for manual underwriting, which means a human reviews your deposit evidence rather than an automated system rejecting it on a technicality.
• Bath Building Society: Case-by-case assessment of deposit sources, particularly helpful for less standard situations.
• Skipton Building Society: Pragmatic approach to deposit evidence, especially for first-time buyers.

Specialist Lenders (For Non-Standard Sources)

• Kensington Mortgages: More open to crypto-sourced deposits and other non-standard sources, provided the paper trail is complete.
• Pepper Money: Flexible on deposit sources as part of their broader non-standard lending approach.
• Together: Known for pragmatic assessment, including deposits from business proceeds or asset sales.

Common Mistakes That Delay Applications

Moving Money Between Accounts

One of the most common issues brokers see is applicants shuffling money between accounts before applying. You might think consolidating all your savings into one account makes things tidier. In reality, it creates a paper trail nightmare. The lender sees large transfers between accounts and wants to know what each one is. If you must consolidate, do it well in advance and keep clear records of every transfer.

Receiving Cash Deposits

If someone hands you £5,000 in cash and you deposit it at the bank, you'll struggle to prove where it came from. Even if it's from a legitimate source (a relative who keeps cash at home, for example), the lack of a traceable transfer makes it very difficult for lenders to verify. Always arrange for funds to be transferred electronically, bank to bank.

Late-Arriving Gifts

A gift that arrives in your account two days before your mortgage application looks suspicious, even if it's been planned for months. If a family member is gifting you deposit money, have them transfer it at least three months before you apply. This gives the lender a settled picture of your finances.

Forgetting About the "Source of Source"

It's not enough to show that your parents transferred £15,000 to you. The lender also wants to know where your parents got that £15,000. If it came from their savings, they'll need to show statements. If they remortgaged their home, that needs explaining. If they sold a car, they'll need the sale documentation. This "source of source" requirement catches many people off guard.

Not Declaring All Sources

Some applicants try to keep things simple by only mentioning their savings, even though part of the deposit is a gift. This is a mistake. If the lender later discovers an undeclared source, it can result in a declined application or, worse, be treated as mortgage fraud. Declare everything upfront.

Questions to Ask Your Broker About Deposit Sources

Before you apply, make sure you discuss these points with your broker:

1. "Is my deposit source likely to cause problems with lenders?" — A good broker will tell you honestly if your source needs special handling.
2. "Which specific lenders are most comfortable with my deposit type?" — Don't waste credit searches on lenders who will reject your deposit source.
3. "What documentation do I need to prepare?" — Get a checklist specific to your situation before you start gathering documents.
4. "Should I wait before applying?" — If a gift has just arrived or you've just sold crypto, your broker might advise waiting a few months for the funds to "season" in your account.
5. "Does the deposit source affect my interest rate?" — In most cases it doesn't, but if your deposit source limits you to specialist lenders, you may pay a premium.
6. "Can I combine multiple deposit sources?" — Yes, most lenders accept combined sources, but each one needs its own documentation trail.

Deposit Gifting and Tax Implications

Receiving a deposit gift doesn't trigger income tax for the recipient in the UK. However, there are inheritance tax implications for the person giving the gift:

• Gifts from a living person become "potentially exempt transfers" (PETs) for inheritance tax purposes
• If the giver dies within 7 years of making the gift, it may be counted as part of their estate for inheritance tax
• The annual gift allowance (currently £3,000 per tax year) can be given tax-free regardless
• Gifts out of surplus income (regular gifts from income the giver doesn't need for their lifestyle) are also exempt

This is a consideration for the giver rather than the borrower, but it's worth being aware of — especially if the gift is substantial.

Preparing Your Deposit Evidence: A Timeline

6 months before applying:

• Start keeping all bank statements showing savings accumulation
• If expecting a gift, have the conversation with the giver about documentation they'll need
• If you have crypto or other assets to sell, consider selling now to allow funds to season

3 months before applying:

• Ensure gifted funds have been transferred to your account
• Get the gifted deposit letter signed and witnessed
• Gather the giver's bank statements showing the source of the gift
• Consolidate any scattered savings into your main deposit account (and keep records of the transfers)

1 month before applying:

• Download or request formal bank statements (not screenshots) from all relevant accounts
• Ensure you have certified ID and proof of address for anyone providing a gift
• Prepare a summary document explaining each deposit source and the amount

At application:

• Provide everything upfront — don't wait to be asked
• Be prepared for follow-up questions and additional document requests
• Have digital copies of everything so you can respond quickly
