My house sale fell through. What do I do now?

If your buyer has just pulled out, the silence afterwards can feel worse than the news itself. It helps to know how normal this is. An estimated 67,489 property transactions collapsed across the UK in the first three months of 2026 alone, up 9.8% on the previous quarter, according to House Buyer Bureau's analysis of TwentyCi data published on 7 July 2026. You are not the exception. You are part of a very large group of sellers who go on to complete a sale, often within weeks.

Why do so many house sales fall through?

A fall-through is when a sale that has been agreed, known as sold subject to contract, collapses before it completes. Most have nothing to do with the seller. They come from the buyer's finances, the buyer's own onward chain, or cold feet after a survey.

The average fall-through cost a UK seller or buyer roughly 3,544 pounds in wasted fees in early 2026, on the same House Buyer Bureau figures, so the sooner you understand the cause, the less a second attempt will cost you.

What should I do first after a sale falls through?

1. 1. Get the real reason in writing

   Ask your estate agent for the specific reason the buyer withdrew, not a vague summary. The cause decides everything you do next, so pin it down before you act.

2. 2. Check your legal position

   Confirm with your solicitor whether you had exchanged contracts. In England and Wales, before exchange neither side is legally committed, so you are free to relist immediately.

3. 3. Relist while you still have momentum

   Tell your agent to put the home straight back on the market. A property that returns quickly looks like a normal relisting, not a problem sale.

4. 4. Sense-check your asking price

   If the sale broke on a down-valuation or a survey, look again at whether the price matches what is actually selling near you now, rather than what you hoped for.

5. 5. Line up your paperwork

   Keep your solicitor instructed and your documents ready so the next buyer can move fast. Speed is the single best protection against a second fall-through.

6. 6. Weigh your next buyer on commitment

   When new offers come in, favour the buyer whose position is strongest, for example a first-time buyer or cash buyer with a mortgage already agreed and nothing to sell.

Can I keep the buyer's deposit or claim my costs back?

Usually no, and this surprises people. In England and Wales a sale only becomes legally binding at exchange of contracts, the moment both solicitors swap signed contracts and the deposit is paid. Before exchange there is no binding contract, so a buyer who walks away owes you nothing and you cannot keep a deposit that has not yet been paid. Scotland works differently, where the deal becomes binding earlier once missives are concluded.

How do I stop my next sale from falling through?

You cannot remove all the risk, but you can lower it by reading a buyer's true commitment and by not running ahead of them. Real commitment shows up in what a buyer has paid for and instructed, not in how keen they sound.

• Favour a buyer with a mortgage agreed in principle and, ideally, nothing of their own to sell.
• Watch for the money markers: a solicitor instructed and paid, searches ordered, a survey booked, a mortgage application submitted. Those cost the buyer real money and signal they mean it.
• Keep your own solicitor instructed early, because that is cheap and keeps momentum on your side.
• Hold off on the big, irreversible moves, such as paying for your own onward purchase or coming fully off the market, until your buyer has put their own money down.
• Keep the sale moving. A buyer who is kept waiting for weeks is a buyer who starts looking at other homes.
