Can I Lose My Deposit on a House?

Whether you can lose your deposit on a house depends on which deposit you mean and when you pull out. In England and Wales, before exchange of contracts you generally have nothing formal at risk, so you can walk away without losing a deposit. After exchange, the deposit you pay (usually around 10% of the purchase price) is genuinely at risk if you fail to complete.

There are also smaller reservation deposits, and Scotland works to different rules. In this insight we explain each type of deposit, exactly when it can be lost, and how the position differs across the UK.

Key Takeaways

  • Before exchange of contracts in England and Wales you usually have no formal deposit at stake, so you can withdraw without losing one.
  • The exchange deposit, typically around 10%, is paid at exchange and is at risk if you then fail to complete.
  • A reservation fee (common on new-builds) is a separate, smaller payment that is often non-refundable regardless of exchange.
  • Scotland binds you earlier, once missives are concluded, so your commitment and risk start sooner than in England and Wales.

The Different Types of "Deposit"

The word "deposit" causes a lot of confusion because it is used for several different payments:

  • The mortgage deposit — your own contribution to the purchase price, the rest being your mortgage. This is not a payment you "lose"; it becomes your equity in the home.
  • The exchange deposit — usually about 10% of the price, paid to the seller's solicitor at exchange of contracts. This is the one most at risk.
  • The reservation fee — a smaller sum, common on new-build purchases, to hold a property while you proceed. It is often non-refundable.

Knowing which one someone means is the key to understanding whether it can be lost.

Before Exchange: Usually Nothing at Risk

In England and Wales, an accepted offer is not legally binding. Until contracts are exchanged, either side can walk away, and you have not usually paid a formal deposit at this stage. So if you withdraw an offer before exchange, there is no deposit to forfeit.

You may still have spent money on searches, surveys, mortgage valuation and legal fees, and that money is generally not refundable. But that is wasted cost, not a lost deposit, and there is no penalty for withdrawing itself.

After Exchange: Your Deposit Is at Risk

Exchange of contracts is the turning point. At exchange you pay the deposit (commonly around 10%) and both parties are legally bound to complete on the agreed date. If you then fail to complete, you are in breach of contract and can lose that deposit.

It can get worse than the deposit

If the seller later sells the property for less than your agreed price, you could also be liable for the difference and their associated costs. So the exchange deposit is a floor, not necessarily a ceiling, on what you might lose. This is why understanding the risks between exchange and completion matters so much before you commit.

Because of this, you should only exchange when you are certain you can complete, with your mortgage funds confirmed and your finances stable.

Reservation Deposits on New-Builds

Buying a new-build often involves paying a reservation fee to take the property off the market while you arrange your purchase. This is typically a few hundred to a couple of thousand pounds and is set out in a reservation agreement.

Read that agreement carefully, because reservation fees are frequently non-refundable, or only partly refundable, if you do not proceed. Unlike the pre-exchange freedom on a standard purchase, a reservation fee can be lost even before you get anywhere near exchange, depending on the developer's terms.

The Scotland Difference

Scotland's system commits you earlier. Offers are made formally through solicitors, and once the parties "conclude missives" (the formal exchange of letters), the contract becomes legally binding, which is sooner than exchange of contracts in England and Wales. From that point, backing out can leave you liable for the seller's losses.

If you are buying in Scotland, ask your solicitor precisely when you become committed, because your deposit and wider liability position begins at a different, earlier stage than a buyer south of the border would expect.

How to Protect Your Deposit

The safest approach is to make sure everything is genuinely in place before you exchange: a confirmed mortgage offer, funds ready, searches and enquiries resolved, and buildings insurance arranged. Avoid new credit before completion so your mortgage cannot be pulled, and if your mortgage offer might expire before completion, sort an extension well ahead of time. Certainty before exchange is what keeps your deposit safe.

Frequently Asked Questions

Do I lose my deposit if the sale falls through before exchange?

No. Before exchange in England and Wales there is normally no formal deposit paid, so nothing is forfeited. You may lose money already spent on searches, surveys and legal fees, but that is not a deposit.

Can the seller keep my deposit if I pull out after exchange?

Yes. Once you have exchanged, failing to complete is a breach of contract, and the seller is generally entitled to keep your deposit and may claim further losses if they have to sell for less.

Is a new-build reservation fee refundable?

It depends on the reservation agreement. Many are non-refundable or only partly refundable if you withdraw. Always read the terms before paying, because unlike a standard purchase, this money can be lost early.

How much deposit do you pay at exchange?

The exchange deposit is usually around 10% of the purchase price, though it can sometimes be negotiated lower. It is separate from your overall mortgage deposit and is the sum most directly at risk if you fail to complete.
