Exchange Deposit Funding: How to Find the Money in England

If you need to fund the deposit due on exchange of contracts in England, you have four realistic routes: your own cleared cash, a gift from family, proceeds from another sale, or short-term borrowing structured around the deal. The right one depends on how fast you must exchange, where your capital is tied up and what your lender will accept. This guide sets out each route, the traps in each, and how professional buyers close the “deposit gap” without stalling a purchase.

TL;DR

• The usual deposit on exchange is 10% of the price, paid in cleared funds to your solicitor before you exchange. Some sellers and developers ask for more.
• Once you exchange, the contract is binding. If you pull out, you can lose the deposit and face a claim for damages.
• Gifted deposits must meet strict lender rules and need evidence of the source of funds, sometimes weeks ahead.
• Where capital is locked up, bridging finance, mezzanine debt or JV equity can fund the deposit, but each needs structuring before you commit.
• Only ever send a deposit to a verified client account of a regulated law firm.

What the exchange deposit is and why it matters

Exchange of contracts is the point at which a sale becomes legally binding. As nidirect’s buying guide puts it, solicitors for both sides have the parties sign a contract, and by signing you agree to complete. The deposit is the buyer’s security for that promise.

The standard figure is 10% of the purchase price, though it is negotiable and the contract sets the actual amount. The Law Society’s Code for signing and exchanging property contracts lists the deposit, its amount and how it is held among the matters solicitors must settle before exchange.

The consequence is simple. Under GOV.UK’s guidance on buying a home, the buyer becomes legally responsible for the property at exchange, and you generally forfeit the deposit, often 10%, if you withdraw afterwards. You may also owe the seller further compensation for losses. So funding must be certain before you instruct your solicitor to exchange, not merely likely.

Cleared funds also take time. Money needs to be with your solicitor in advance, so a transfer that lands on the morning of exchange is already too late in many cases.

The deposit gap: where the shortfall comes from

Most buyers who struggle at this stage are not short of wealth. They are short of liquidity at the right moment. Typical situations:

• Capital locked in another asset. A buyer owns a portfolio, a business or a development, but the cash is not accessible in the next fortnight.
• A sale that has not yet completed. You are buying before the proceeds from your own sale arrive.
• A fast sale route. Auction and development purchases move quicker than a standard mortgage process.
• A higher deposit demand. Off-plan developers often ask for far more than 10%. The Law Society’s commentary on off-plan purchases discusses what happens to the contract deposit if the developer becomes insolvent before the building is finished.

The mortgage itself does not solve this. A mortgage advance is released on completion, not on exchange, so the deposit must come from elsewhere.

Route 1: your own cash and savings

The simplest route is also the cleanest. Cash in your own bank account, held long enough to show a clear history, moves quickly and raises few questions.

What to do:

1. Ask your solicitor how much they need and by when, and whether they want it the day before exchange.
2. Transfer only to the client account details your solicitor has given you, confirmed by phone on a number you already trust.
3. Keep statements showing where the money came from. Your solicitor has anti-money-laundering duties and will ask.

If you are moving money out of savings accounts with notice periods, or out of investments that need selling, start early. Settlement times can sink an exchange date.

Route 2: a gifted deposit

Family gifts are common, but lenders police them closely. According to the UK Finance Mortgage Lenders’ Handbook entry for Nationwide, conveyancers must deal with the position where deposit money is not from the borrower’s own funds and report to the lender in set ways. In practice, most lenders expect a gift to be:

• unconditional and non-repayable
• free of any legal charge or security over the property
• from a family member, with the source of funds confirmed

Reporting also extends to unusual origins. Lenders are increasingly cautious about funds that began as crypto-assets, and money arriving from abroad needs specific reporting. Some lenders want gift paperwork at least two weeks before exchange so it can be reviewed manually, so ask your solicitor which lender rules apply to you.

The giver should sign a gifted deposit letter, and your solicitor will want to see the donor’s identity and bank evidence. If a family member is releasing money by remortgaging, lenders will want that trail documented too. A UK builder’s explanation of documenting the origin of funds when family help with a purchase or remortgage shows how that evidence typically looks from the borrower’s side.

The worst outcome is a lender stopping the file because a gift letter was vague. Prepare the paperwork before you agree an exchange date.

Route 3: proceeds from a property sale

If you are selling to buy, the usual route is that your own sale and purchase exchange on the same day. The deposit you receive on your sale is often used toward the deposit on your purchase.

The Law Society code explains the effect in a chain: the deposit from the bottom of the chain is often passed up to meet the deposit requirement in the contracts above it. There is a catch. If you have not put in your own 10%, you may be bound under Standard Condition 6.8.3(b) to top the deposit up to 10% on the day of completion if the deal fails because of your default. That applies even where the delay was caused by someone higher in the chain. Ask your solicitor to explain how the clause bites in your own chain before you agree to a reduced deposit.

A lower deposit is sometimes agreed, with 5% seen in some cases, but the seller must be willing, and it carries this top-up risk. It is not a loophole.

Route 4: short-term finance structured around the deal

When the money exists but cannot be reached in time, borrowing against another asset is the professional answer. The main options:

In complex acquisitions, the deposit is often not a plain cash injection. It becomes a negotiated element of the whole capital stack. Using mezzanine debt or JV equity to meet the deposit keeps cash on the balance sheet while you secure the site.

Two cautions apply. First, lenders look at the deposit’s source, so borrowed deposit money must be disclosed to your senior lender, not tucked away. A second charge or additional borrowing can affect what your main lender will permit, so the structure has to be agreed with all parties before exchange. Second, short-term finance needs a clear exit, such as a sale or refinance. Without a credible exit, you have swapped a deposit problem for a larger one. If you hold an existing bridge nearing its term, our note on how to refinance a maturing bridging loan covers the options.

Protecting the deposit once you have paid it

A deposit is a large sum leaving your account, so the controls matter.

Stakeholder or agent. Normally the seller’s solicitor holds the deposit as stakeholder, meaning it stays put until completion. If you agree to pay as agent, the seller’s side can release the money immediately on exchange. The Law Society’s Soluble problem feature describes a buyer who agreed to pay a £96,000 deposit to the seller’s solicitors as agents rather than the usual stakeholder arrangement. If the seller then becomes insolvent, you may rank only as an unsecured creditor. Careful conveyancers often run a bankruptcy search (K16) before exchange where the deposit will be released.

Off-plan and high deposits. Developers can demand 20% to 50%, and standard warranty schemes typically cap protection at 10% or a fixed sum. For larger sums, legal structuring such as an equitable lien may be needed to secure a claim against the property. This is a conversation for your solicitor before you sign.

Payment fraud. Criminals pose as conveyancers and divert deposits. Pay only into the client account of a regulated law firm, using details you have verified by phone, never from an unsolicited email or message.

Insurance. Buildings insurance needs to be in place from exchange, not from completion, because the risk passes to you at exchange.

What if you cannot complete after exchange?

Failing to complete is expensive. You can lose the deposit, the seller can serve notice to complete and claim for losses, and a fall in the property’s value can add to the bill. If you are facing a seller’s claim or an unpaid debt arising from a collapsed transaction, a service that matches you with vetted collection specialists, such as this guide to landlord debt recovery in the UK, shows how recovery works from the other side of the table. But the better move is to line up a fallback, such as a bridging facility agreed in principle, before you exchange.

Our perspective: treat the deposit as part of the capital structure

We work with developers, investors and business owners whose deals rarely look like a standard purchase. In our experience, the deposit is where a well-planned transaction either holds together or starts to slip.

The mistake we see most is treating the deposit as a last-minute payment. It is a funding decision that should be taken when the offer is made. That means asking three questions early:

1. Where does every pound of the deposit come from, and can you evidence it?
2. If the senior lender, the sale or the gift slips by two weeks, what is the fallback?
3. Does the structure we choose leave room for the exit?

Because we arrange bridging, development finance, mezzanine debt and JV equity alongside commercial and residential mortgages, we can look at the deposit and the main facility together rather than as separate problems. We work with specialist lenders, private credit funds and family offices beyond the high street, so a deposit that a bank cannot fund in the time available may still be fundable. Our guide to stacking debt in a tight-margin development shows how we approach layered structures.

The honest limit: no structure replaces a sound exit. If the numbers only work when everything goes perfectly, we will say so before you exchange.

A practical timeline to work back from

Whatever route you choose, work backwards from the exchange date you want.

These timings are a planning guide, not a rule. Your lender and solicitor set the actual deadlines, so ask each for theirs in writing.

FAQ

How much deposit do you pay on exchange?

Usually 10% of the purchase price, paid in cleared funds to your solicitor. The figure is set in the contract, so it can be lower by agreement, or higher, as with many off-plan purchases.

Can you use money from a house sale as your deposit?

Yes, and it is common where the sale and purchase exchange on the same day. The deposit from your buyer can pass up the chain to your seller. Check with your solicitor whether you are exposed to a top-up if you did not put in your own 10%.

Is there a limit on a gifted deposit?

The law sets no single cap that applies to gifts for a purchase. Limits are set by lenders, who typically require the gift to be non-repayable, unsecured and from a family member, with the source of funds confirmed. Check your own lender’s requirements through your solicitor.

What happens if I cannot pay the deposit on exchange?

You should not exchange. If you fail to pay what the contract requires, or fail to complete afterwards, you risk losing the deposit and a damages claim. If cash is the issue, speak to a broker about bridging or other short-term finance before the exchange date, not after.
