Buying a house is one of the biggest financial commitments most people make, and one of the most common questions buyers ask is when the deposit has to be paid. In the UK, there are actually two separate payments often referred to as a “deposit” during the home-buying process, which can cause confusion for first-time buyers. Understanding when each deposit is due, how much it should be, and what it covers can help you plan your finances more effectively and avoid unnecessary stress as you move towards completion.

The two main deposits are the mortgage deposit, which forms part of the property’s purchase price, and the exchange deposit, which is paid to the seller’s solicitor when contracts are exchanged. Knowing how both work and when they are due is essential for a smooth transaction.

The difference between a mortgage deposit and an exchange deposit

The term “deposit” is used in two different ways in property transactions, and each plays a separate role. The mortgage deposit is the amount you pay upfront towards the property’s price, reducing the amount you need to borrow from your mortgage lender. It typically ranges from five to twenty per cent of the purchase price, depending on the mortgage product.

The exchange deposit, on the other hand, is paid later in the process when contracts are exchanged. This is usually ten per cent of the property price and serves as a financial commitment to the seller, confirming that you intend to go ahead with the purchase.

The key difference is timing and purpose. The mortgage deposit contributes to the overall cost of the property, while the exchange deposit acts as security for the seller until completion.

When the mortgage deposit is paid

Your mortgage deposit is paid on the day of completion, which is when you officially take ownership of the property. The funds for the purchase are transferred from your mortgage lender and your own savings to the seller via your solicitor.

Throughout the buying process, your solicitor will prepare a financial statement showing exactly how much you need to pay and when. This includes the deposit, legal fees, stamp duty, and other costs. You will usually need to transfer your deposit money to your solicitor a few days before completion so they can hold it in a secure client account, ready for the transaction.

Before this point, you do not pay your mortgage deposit directly to the seller or estate agent. It remains in your control until it is time for the solicitor to use it as part of the completion funds.

When the exchange deposit is paid

The exchange deposit is paid when contracts are formally exchanged between the buyer and seller, which is typically a week or two before completion. This deposit is usually ten per cent of the purchase price, although in some cases a smaller amount can be agreed if the buyer is putting down a lower mortgage deposit.

For example, if you are buying a £300,000 house with a ten per cent mortgage deposit, you will need to pay £30,000 at completion, but your solicitor will also need a ten per cent exchange deposit at the exchange of contracts. In practice, this is often the same money. Your solicitor will hold it until completion, so you do not need to pay the full amount twice.

When contracts are exchanged, both parties are legally committed to completing the sale. If you, as the buyer, pull out after exchange, you could lose your deposit, which is why this stage requires absolute certainty that you are ready to proceed.

How the process works

In a typical UK property purchase, the process leading up to paying your deposit follows several key stages. Once your offer has been accepted, your solicitor will begin the conveyancing process and your mortgage application will be submitted. At this stage, you usually do not need to pay any large sums beyond your mortgage valuation fee or initial legal fees.

Once the mortgage offer is issued and the conveyancing searches and surveys are complete, your solicitor will confirm that both sides are ready to exchange contracts. Before the exchange takes place, your solicitor will request the exchange deposit from you. You will need to transfer this money to their client account so they can pay it on your behalf when the contracts are exchanged.

At completion, the balance of the purchase price is paid, made up of your remaining deposit funds, your mortgage amount, and any other associated costs. This is the point at which the property legally becomes yours and you can collect the keys.

How much you need for the deposit

The amount of deposit you need depends on your mortgage and the property’s value. Most mortgage lenders in the UK require at least a five per cent deposit, meaning that for a £250,000 home, you would need at least £12,500. However, larger deposits often lead to better mortgage rates because they reduce the lender’s risk.

For example, buyers with ten or fifteen per cent deposits often qualify for lower interest rates and have access to a wider range of mortgage products. First-time buyers may also be eligible for government schemes such as the Lifetime ISA or shared ownership, which can help boost their deposit or reduce the upfront cost.

What happens to the exchange deposit

When you pay the exchange deposit, your solicitor transfers it to the seller’s solicitor, where it is held securely until completion. It acts as a sign of good faith and provides financial protection for the seller.

If the sale falls through after exchange because the buyer withdraws, the seller has the right to keep the deposit as compensation. However, if the seller pulls out without good reason, the buyer is entitled to have their deposit returned and may also be able to claim additional costs through legal channels.

In most cases, the exchange deposit becomes part of the final purchase price at completion, so you are not paying any extra overall. It simply moves from being a commitment payment to being part of your total house deposit.

Timing and coordination with your solicitor

The timing of paying your deposit requires close coordination between you, your solicitor, and your mortgage lender. Your solicitor will tell you exactly when to transfer your funds, often asking for them several working days before exchange or completion to allow for bank clearance and compliance checks.

Most solicitors prefer to receive deposit funds by electronic transfer (CHAPS or Faster Payments) rather than cheques, as it is faster and more secure. You should always verify bank details directly with your solicitor to avoid fraud.

It is also worth ensuring your deposit funds are readily accessible when needed. Money tied up in fixed-term savings or investments can take time to release, which could delay your transaction.

Deposit arrangements for first-time buyers

First-time buyers often find the deposit stage the most challenging part of the process. Saving for a mortgage deposit can take years, and understanding when and how it is used is crucial for budgeting effectively.

The exchange deposit may come directly from your mortgage deposit savings, so your solicitor will handle it on your behalf. You will not need to pay two separate amounts, but you must make sure the money is available well before exchange to avoid delays.

If you are using a Lifetime ISA or Help to Buy ISA, you will need to allow time for the funds to be released and transferred to your solicitor’s account before completion. Your solicitor will guide you through the exact timing to make sure the money is available when needed.

What happens if you cannot pay the deposit

If you cannot provide the required exchange deposit when contracts are due to be exchanged, your purchase may be delayed or even collapse. Sellers and their solicitors will not usually agree to exchange without receiving the full deposit amount.

In some cases, if you are putting down a smaller overall mortgage deposit (for example, five per cent), your solicitor may be able to negotiate a lower exchange deposit with the seller. This agreement must be reached in writing and approved by both parties before exchange.

If you fail to complete the purchase after exchange, you risk losing the deposit and could also face legal action for breach of contract. Therefore, you should only exchange contracts once you have your mortgage offer, funds in place, and are certain you can proceed.

Refunds and deposit protection

The deposit paid during a house purchase is protected under UK conveyancing law. Solicitors hold client funds in regulated accounts, and all transactions are subject to strict anti-fraud and money-handling rules.

If the sale does not proceed before exchange, your deposit will be refunded in full. Once contracts are exchanged, however, the deposit is legally binding and cannot be refunded unless the seller fails to complete the sale.

It is also important to note that deposits are handled differently in new-build purchases. Developers may require a reservation fee or early deposit to secure the property, which may be partially non-refundable. Always read the terms carefully before paying any money.

Preparing for the deposit stage

To make the process as smooth as possible, start preparing your deposit funds early in the buying journey. Keep your money in an accessible account, and make sure your solicitor knows where the funds are coming from, as they must comply with anti-money-laundering regulations.

You should also budget for additional expenses such as stamp duty, legal fees, survey costs, and moving expenses, as these are separate from your deposit.

If you are receiving financial help from family, such as a gifted deposit, your solicitor will need a formal letter from the donor confirming that the money is a gift, not a loan.

Conclusion

You pay your house deposit in two stages during the buying process: an exchange deposit, usually ten per cent, when contracts are exchanged, and the remaining mortgage deposit at completion. Both are managed by your solicitor and form part of the overall purchase price.

Understanding how and when these payments occur helps you stay financially prepared and prevents last-minute issues. By keeping your funds accessible, coordinating with your solicitor, and confirming your mortgage in advance, you can move through the buying process confidently and smoothly, knowing your deposit is secure and properly handled.
