Your sale fell through. Here is what actually happens next.
An accepted offer in England and Wales binds nobody. Until contracts are exchanged — typically eight to twelve weeks after the offer — either side can walk away for any reason or none, and owe the other nothing.
That is why around a third of agreed sales collapse, and why the collapse usually arrives late, after both sides have spent money. The seller has paid for searches and legal work. The buyer has paid for a survey and a valuation. Neither gets any of it back.
Where the money goes
Legal work
Conveyancing already carried out on a transaction that will not complete. Rarely recoverable, and often re-done from scratch for the next buyer.
Survey and valuation
Paid by the buyer, and wasted if they walk — which is why a buyer who has spent on a survey is less likely to be the one who withdraws.
Time off the market
The quiet cost. A property marked sold subject to contract for ten weeks re-enters the market looking stale, and stale listings attract lower offers.
The chain
If you were buying on, your purchase is now at risk too. One collapse frequently takes several transactions with it.
The four reasons sales collapse
The buyer changed their mind. They found somewhere they preferred, got cold feet, or were never fully committed. Nothing held them.
The mortgage was refused or down-valued. An agreement in principle is not an offer. When the lender's valuation comes in under the agreed price, the buyer has to find the difference in cash or renegotiate.
The survey found something. Sometimes genuine, sometimes a lever. Either way it reopens a price that both sides thought was settled.
The chain broke somewhere else. The most frustrating version, because nothing was wrong with your sale at all.
What reduces the risk on the next buyer
You cannot make an offer binding before exchange. What you can do is make withdrawing cost something, so that the buyer who is only half-committed either commits properly or declines at the start — before anybody has spent.
That is what a reservation agreement does. The buyer pays a reservation fee, which is held securely until exchange or refund of the fee as per the terms of the agreement. The property comes off the market. If the buyer withdraws outside the agreed reasons, they forfeit the fee. If the seller withdraws, or something material was never disclosed, the buyer gets it back.
The reservation fee is paid on top of the agreed purchase price, not taken out of it, so the seller's position is unchanged and the buyer is demonstrating commitment with their own money.
Choosing between two offers
A buyer willing to put a reservation fee behind their offer is telling you something a higher offer with no commitment cannot. Sellers and agents routinely take the slightly lower offer that will actually complete.
If it has already happened
Go back to market quickly rather than waiting — a listing that reappears after a long gap invites "what's wrong with it" questions. Ask your agent for the second and third offers from the first round; those buyers are often still looking. And ask whether they can put a reservation agreement in place this time.
If your agent does not offer one, you can tell us who they are and we will approach them.
Common questions
How often do house sales fall through in the UK?
Roughly one in three agreed sales in England and Wales collapses before exchange, and in some areas agents report rates closer to one in two. Until contracts are exchanged, either side can walk away without penalty.
How much does a fall-through cost the seller?
Most sellers lose their survey and legal spend on the failed transaction, plus the cost of the time the property sat off the market. Where the seller was buying on, the collapse often takes their onward purchase with it.
Can I sue a buyer who pulls out?
Before exchange of contracts, no. An accepted offer is not binding in England and Wales. That is the gap a reservation agreement is designed to close, because it creates a commitment that exists before exchange.
