Exchange Deposit Explained for Sellers

The exchange deposit is one of the most important financial mechanisms in the English and Welsh property system. It is the sum of money the buyer pays on exchange of contracts to demonstrate their commitment to the purchase and to provide you, the seller, with a financial safety net if the deal falls through after exchange.

Despite its importance, many sellers are unsure exactly how much deposit to expect, where the money goes, who controls it, and what protections it actually provides. This guide covers all of these questions in detail, with particular focus on what sellers in England and Wales need to know.

What is the exchange deposit?

The exchange deposit is a lump sum paid by the buyer on the day contracts are exchanged. Exchange is the point at which the sale becomes legally binding — before exchange, either party can withdraw without penalty. After exchange, both buyer and seller are contractually committed, and the deposit secures that commitment.

The deposit serves two primary purposes:

• Evidence of commitment. By paying a substantial sum upfront, the buyer demonstrates they are serious about completing the purchase. This gives the seller confidence to proceed with their own plans, including any onward purchase.
• Financial protection for the seller. If the buyer fails to complete after exchange, the seller is entitled to forfeit the deposit as compensation. This acts as a powerful incentive for the buyer to follow through.

The deposit is distinct from the buyer's mortgage deposit (the equity they put towards the property). The exchange deposit is a separate payment made to your solicitor as part of the contractual exchange process. For more on the broader exchange process, see our guide on exchange of contracts explained for sellers.

How much deposit should you expect?

The standard exchange deposit in England and Wales is 10% of the purchase price. This is the default amount specified in the Standard Conditions of Sale (6th Edition), which form the basis of most residential property contracts.

In practice, reduced deposits of 5% are increasingly common. This is particularly the case where the buyer is a first-time purchaser who has stretched to raise their mortgage deposit and has limited additional cash available for the exchange deposit. According to the HomeOwners Alliance, reduced deposits are now accepted in a significant proportion of residential transactions, though 10% remains the standard that most solicitors will advise their clients to aim for.

Should you accept a reduced deposit?

As the seller, you have the right to insist on the full 10%. However, refusing a reduced deposit could mean losing a buyer who is otherwise well-positioned to complete. Your solicitor should advise you on the balance of risk. Key factors to consider include:

• Buyer's overall position. A first-time buyer with a mortgage offer in place, no chain, and a 5% deposit may be less risky than a chain buyer offering 10% who still needs to sell their own property. See our guide on how to vet a buyer for more on assessing buyer strength.
• Your chain position. If you are buying onward and need the deposit to fund your own onward purchase deposit, a reduced deposit from your buyer could create a shortfall.
• Market conditions. In a slow market, a 5% deposit may not cover your losses if the buyer defaults and you have to resell at a lower price.
• Contractual damages clause. Your solicitor can negotiate a contractual term that makes the full 10% payable as damages if the buyer defaults, even if only 5% is paid upfront. This provides additional protection, though recovering the difference from a defaulting buyer can be difficult in practice.

Where does the deposit go?

On the day of exchange, the buyer's solicitor transfers the deposit to your solicitor. Your solicitor then holds the deposit in their regulated client account — a bank account held at an authorised bank or building society, entirely separate from the firm's own business account. This separation is a fundamental requirement of the SRA Accounts Rules 2019.

The deposit remains in this client account until completion day, at which point it forms part of the total purchase price. Your solicitor cannot use the deposit for any other purpose while they hold it. For more detail on how solicitors handle this money, see our guide on solicitor-held deposits explained.

Stakeholder vs agent: a critical distinction

Under the Standard Conditions of Sale, the deposit is held by your solicitor as stakeholder. This is the default and by far the most common arrangement. As stakeholder, the solicitor acts as a neutral third party:

• The deposit cannot be released to the seller before completion.
• If the sale falls through lawfully, the deposit is returned to the buyer.
• If the buyer defaults, the deposit is forfeited to the seller.

In rare cases, the contract may specify that the deposit is held as agent for the seller. This allows the solicitor to release the money to you before completion. However, buyers' solicitors almost universally resist this arrangement because it removes the buyer's protection, and most mortgage lenders require the stakeholder arrangement as a condition of their mortgage offer.

The deposit in a property chain

Property chains add significant complexity to how deposits are handled. In a chain, the deposit paid by the buyer at the bottom is typically passed up through the chain on the day of exchange, rather than each buyer providing a separate deposit from their own funds.

The Law Society's exchange formulas facilitate this process:

• Formula A is used for straightforward exchanges where deposits are held by the seller's solicitor.
• Formula B is used where the seller's solicitor in one transaction is also acting as the buyer's solicitor in the next transaction in the chain, and the deposit needs to be transmitted onwards.
• Formula C is used for more complex chains where multiple exchanges need to be synchronised and deposits passed through several links.

Here is a practical example. Consider a three-property chain where all parties exchange simultaneously:

1. Buyer A (first-time buyer) pays a £20,000 deposit (10% of their £200,000 purchase).
2. Seller A / Buyer B receives that £20,000 deposit and their solicitor transmits it onwards as part of the deposit on their £350,000 onward purchase. The full 10% would be £35,000, so there is a £15,000 shortfall that may need to be topped up or negotiated as a reduced deposit.
3. Seller B (at the top of the chain) receives the deposit, held by their solicitor as stakeholder until completion.

Each solicitor in the chain gives a professional undertaking to hold and transmit the deposit on the agreed terms, so the legal protections remain in place throughout. For more on what happens between exchange and completion in a chain, see our guide on what happens between exchange and completion.

What protections does the deposit provide?

The exchange deposit is the seller's primary financial protection after contracts are exchanged. It is what gives exchange its weight in the English and Welsh property system. Before exchange, either party can walk away with no financial consequences. After exchange, real money is at stake.

If the buyer defaults

If the buyer fails to complete after exchange, the process is governed by the Standard Conditions of Sale:

1. Your solicitor serves a notice to complete, giving the buyer 10 working days to finalise the purchase.
2. If the buyer still fails to complete within the notice period, you can rescind (cancel) the contract.
3. On rescission, you are entitled to forfeit the entire deposit. If the contractual deposit was 10% but the buyer only paid 5% upfront, the buyer owes the difference.
4. You can also claim additional damages for any losses exceeding the deposit amount — for example, if you have to resell at a lower price, or if you incur storage and temporary accommodation costs.

On a £350,000 property with a 10% deposit, forfeiting the deposit means keeping £35,000. This is a substantial sum and explains why buyers very rarely default after exchange. For more on what to do if your buyer pulls out, see our guide on what to do if the buyer pulls out.

If you default as the seller

The protections work both ways. If you fail to complete after exchange:

• The buyer's solicitor can serve a notice to complete, giving you 10 working days.
• If you still fail to complete, the buyer can rescind the contract and recover their deposit in full.
• The buyer can claim damages for all their losses, including legal fees, survey costs, mortgage arrangement fees, and any price difference if they have to buy a more expensive property.
• The buyer may seek a court order for specific performance, forcing you to complete the sale.

This is why exchange of contracts is treated so seriously. Once you exchange, you are legally committed and the financial consequences of not completing are severe in both directions.

When is the deposit released?

The deposit is released on completion day. When the buyer's solicitor sends the balance of the purchase price via CHAPS bank transfer, the deposit already held by your solicitor is combined with the incoming funds to make up the full purchase price.

Your solicitor then distributes the total proceeds according to your completion statement, which will show deductions for:

• Your outstanding mortgage redemption amount
• Estate agent fees
• Solicitor's fees and disbursements
• Any other agreed costs

The remaining balance is transferred to your bank account, usually within one to two working days of completion. The deposit is not paid to you separately or in advance — it forms part of the total purchase price and is distributed through the same process as the rest of the funds.

Regulatory protections around the deposit

The deposit held by your solicitor is protected by multiple layers of regulation. Understanding these protections can give you confidence that the money is secure.

• SRA Accounts Rules 2019. These rules require solicitors to keep client money in a separate client account, never mixed with the firm's own money. Breaches can result in fines, practising conditions, or being struck off the roll.
• Annual audit. The firm's client account is subject to annual review by an independent reporting accountant, adding a layer of external oversight.
• Insolvency protection. Money in a solicitor's client account does not form part of the firm's assets. If the firm becomes insolvent, creditors cannot claim against it. The SRA intervenes to ensure client funds are returned.
• SRA Compensation Fund. If a solicitor misappropriates client money, the SRA Compensation Fund can provide a grant to cover the loss.
• Professional indemnity insurance. All practising solicitors must hold professional indemnity insurance, which can cover claims arising from negligence in handling client funds.

You can verify that your solicitor is properly regulated by searching the SRA's online register at sra.org.uk. If using a licensed conveyancer rather than a solicitor, the equivalent regulator is the Council for Licensed Conveyancers (CLC).

Interest on the deposit

If there is a gap of several weeks between exchange and completion (which is common — the typical gap is two to four weeks), you may wonder whether the deposit earns interest while sitting in your solicitor's client account.

Under the SRA Accounts Rules, solicitors must account to the client for a fair sum of interest when it is reasonable to do so. In practice:

• For large deposits held for several weeks, the solicitor may place the funds in a designated interest-bearing client account.
• For shorter periods or smaller amounts, the interest earned may be negligible and the solicitor may not be required to account for it.
• Some firms have a minimum threshold (for example, £20 or £50) below which they do not pay out interest.
• The solicitor may deduct a reasonable administration charge from any interest paid.

Ask your solicitor at the outset what their policy on interest is, particularly if there is likely to be a long completion period.

Practical tips for sellers

While the legal framework around exchange deposits is well-established, there are practical steps you can take to protect your position:

1. Discuss the deposit amount early. Ask your solicitor to confirm the expected deposit amount before exchange. If the buyer's solicitor proposes a reduced deposit, you should understand the implications before agreeing.
2. Confirm the holding arrangement. Make sure the deposit will be held as stakeholder (the standard). If anyone proposes an agent arrangement, discuss it carefully with your solicitor.
3. Understand your chain position. If you are in a chain, ask your solicitor how the deposit will flow through the chain and whether there will be any shortfall on your onward purchase.
4. Prepare for completion. Once you have exchanged and the deposit is paid, start preparing for completion day. The deposit provides security, but the goal is always to reach completion smoothly.
5. Keep your paperwork in order. The faster you can progress from offer to exchange, the sooner the deposit is paid and your sale becomes legally binding. Preparing your legal pack in advance using a service like Pine helps reduce the gap between accepting an offer and reaching exchange.

Common misconceptions about the exchange deposit

Several misunderstandings about the exchange deposit are widespread among sellers. Here are the most common:

What to do if there are deposit problems

Deposit-related issues are uncommon but can arise. The most frequent problems sellers encounter include:

• Buyer cannot raise the full 10%. If the buyer proposes a reduced deposit, your solicitor will advise on whether to accept. In some cases, you may agree to 5% but include a contractual clause making the full 10% payable as damages on default.
• Deposit not received on exchange day. Your solicitor should not exchange contracts until the deposit has been received and cleared. If the buyer's solicitor cannot confirm the funds are available, exchange should be delayed.
• Chain deposit shortfall. In a chain, the deposit passed up from below may not cover the full 10% on your onward purchase. Your solicitor should flag this early so you can plan accordingly.
• Buyer defaults after exchange. If this happens, follow your solicitor's advice on serving a notice to complete and, if necessary, rescinding the contract and forfeiting the deposit. See our guide on what to do if the buyer pulls out for a full breakdown of your options.
