Moving home is an exciting milestone, but the legal and financial steps involved can sometimes feel daunting—especially for first‑time buyers. One area that often causes confusion is the exchange deposit. What it is, when it is required, and how it differs from the mortgage deposit are all important factors to understand before reaching the exchange stage of a property purchase.
This article breaks down the essentials, helping buyers feel confident and informed throughout the process.
What Is an Exchange Deposit?
The exchange deposit is a sum of money paid by the buyer to the seller—typically via their solicitors—at the point of exchange of contracts. This is the moment when the transaction becomes legally binding for both parties.
Once contracts are exchanged, neither side can withdraw without facing significant financial penalties, so the exchange deposit acts as a form of security for the seller.
How Much Is the Exchange Deposit?
Under the Standard Conditions of Sale, the standard exchange deposit is usually 10% of the property’s purchase price.
Example:
If you are buying a home for £250,000, the standard exchange deposit would be £25,000.
However, variations are common. Circumstances in which a reduced exchange deposit may be agreed include:
- High loan‑to‑value mortgages: A buyer securing a 95% mortgage may provide a 5% deposit instead of the standard 10%.
- Negotiated terms: In some cases, the parties simply agree to a different amount.
Any departure from the standard 10% should be agreed between the solicitors acting for the buyer and seller.
Deposit Funds on a Linked Sale and Purchase
Many buyers find themselves not only purchasing a new property but also selling their existing home at the same time. In these linked transactions—often referred to as a chain—understanding how exchange deposits work on both sides is crucial.
When a seller receives an exchange deposit, it is calculated as 10% of the sale price. For example, if you are selling your home for £250,000, the buyer will typically provide a £25,000 deposit on exchange.
However, if your onward purchase is for £500,000, the standard 10% deposit required by your seller would be £50,000. This creates a £25,000 shortfall between the deposit you receive on your sale and the deposit you are required to provide on your purchase.
Your solicitor will determine whether you are in a position to “top up” the deposit to meet the full 10% required on the onward purchase. In some cases, this is possible using available savings or funds.
If topping up is not possible, solicitors will often negotiate with the seller on your onward purchase to agree to a reduced exchange deposit. This is not uncommon in chain transactions, especially where all parties are motivated to proceed and the overall financial position is sound.
Understanding this difference in deposit requirements—and discussing options early—helps ensure a smoother exchange process, particularly when coordinating both sale and purchase transactions
When Is the Deposit Payable?
Before the exchange of contracts takes place, the buyer’s solicitor will:
- Request the exchange deposit from the buyer
- Hold the funds in readiness for exchange
- Transfer the deposit to the seller’s solicitor immediately after exchange
The seller’s solicitor then retains the deposit until completion, when the remaining purchase monies are transferred.
What Does “Held to Order” Mean?
There are situations where the buyer’s solicitor may keep the deposit instead of sending it to the seller’s solicitor immediately upon exchange. This arrangement is known as Held to Order.
This typically occurs in property chains, where:
- Several transactions are linked
- Funds need to move up the chain quickly
- There isn’t enough time between exchange and completion for money transfers to circulate through all parties
When a deposit is held to order, the buyer’s solicitor holds the deposit on the seller solicitor’s behalf and releases it alongside the balance of purchase funds on completion day.
This ensures the chain can proceed smoothly without the risk of delays in bank transfers derailing completion.
Exchange Deposit vs Mortgage Deposit: What’s the Difference?
A common misconception is that the exchange deposit and the buyer’s personal contribution to the purchase (often referred to as the mortgage deposit) are the same thing—but they serve very different purposes.
Exchange Deposit
- Paid at exchange of contracts
- Typically 10% of purchase price
- Acts as security for the seller
- Held by solicitors until completion
Mortgage Deposit
- The amount the buyer is contributing personally towards the purchase
- Paid on completion, alongside mortgage funds
- Could be more or less than 10%, depending on the mortgage product and buyer’s financial commitment
For example, a buyer may be contributing 20% of the purchase price overall, but only needs to provide a 10% exchange deposit at the point of exchange. The remaining 10% is due on completion.
Final Thoughts
Understanding how exchange deposits work gives buyers greater confidence during the purchasing process. While the terminology can feel technical, the concept is straightforward once broken down: the exchange deposit secures the transaction at the point when contracts become binding and protects the seller from sudden withdrawal.
Your solicitor will guide you through the exact requirements for your transaction, ensuring that all funds are requested and transferred at the correct stages. Being informed simply helps you feel more in control as you move toward completion—and into your new home.
