If your house sale has fallen through, tell your solicitor and take a moment to assess your options. If you need to sell quickly, it is worth considering alternative ways to sell, including auction. Around one in three estate agent sales in England and Wales falls through, because an accepted offer is not binding until exchange. Auction is different: at an unconditional auction, contracts are exchanged when the hammer falls. It is a more secure process, giving the seller far more certainty.
A sale that collapses after weeks or months of waiting is one of the most frustrating parts of selling a home, and it is common. This guide is for you if you are selling a house or flat through an estate agent and your sale has just fallen through. It also helps if your sale has stalled and you are worried that it might. It covers what to do first, why sales fail, how to protect your next sale, and the other ways to sell, including auction.
What to do at a glance
- Tell your solicitor, then assess your options. This is a fork in the road: rushing to accept the next offer risks another collapse, while a considered choice now can make all the difference.
- An accepted offer is not binding. With an estate agent, the buyer can pull out or lower their offer at any time before contracts are exchanged. That can be months after you accepted the offer.
- An auction sale is binding on auction day. At an unconditional auction, the buyer exchanges contracts and pays a 10% deposit the moment the hammer falls. They cannot then pull out or lower their offer.
- Watch for the warning signs. A sale rarely collapses without warning. If the buyer's solicitor goes quiet, or the survey keeps being put off, ask questions early.
- You can make the next sale safer. The last sale will have taught you something about why sales fail. Next time, check that the buyer has the money, prefer a buyer with no chain, and agree dates for each stage.
- There are other ways to sell. Auction gives you a binding sale on a fixed date. A cash buying company can be quick, but it is still a private treaty sale and can fall through. Waiting suits you if there is no rush.
What to do when your house sale falls through
What to do: Sales fall through more often than you might think, and much of the legal work can be used again for the next buyer. Treat this as a fork in the road: tell your solicitor, then take a day or two to choose your route rather than simply accepting the next offer that comes along.
A collapsed sale is a setback, but it does not always put you back at the very beginning. Work through these six steps in order.
- Was the problem with the buyer or with the property? Sales often fail because of the buyer. Their mortgage was refused, their own sale collapsed, or their plans changed. If that is what happened, the property itself was not the issue, and there is no reason to reduce the asking price.
- Decide whether you want to know what the survey found. This is a tricky one. Once you know about a problem with the property, you have to declare it to the next buyer on the property information form. If you never find out, there is nothing to declare. Knowing lets you fix the problem or price for it. Not knowing keeps things simple. Neither is wrong, but make the choice on purpose.
- Tell your solicitor. Ask what you owe for the work so far, and ask them to keep your file open. The property forms, title documents and draft contract can all be used for the next buyer, so the next sale starts further along.
- Let your estate agent update the chain. Your agent will tell the other agents, including the agent selling the home you are buying. That seller will usually give you some time to find a new buyer, as starting again would set them back too. If you have a mortgage offer for the home you are buying, check when it expires.
- Pause before you go back on the market. This is the fork in the road. The easy route is to ask your agent to find another buyer. That means instructing them all over again, and the next sale could fall through just like the last one. The other route is to weigh up your options first; think about whether it was the buyer or the property that let you down, and what you would do differently this time.
- Decide how to sell next. You can try again with an estate agent, or choose a different method of sale. The options are compared below.
Two questions after a failed sale: was the problem the buyer or the property, and what matters most to you now. The answers point to the route that suits you.
Do you need to reduce the price?
Not always. Estate agents often suggest a price cut after a sale falls through. A cheaper property is easier to sell, so it is the simplest thing for them to recommend. But if the sale failed for a reason that had nothing to do with price, there is no need to cut it.
Keep the original asking price if:
- the sale fell through because of the buyer, not the property
- you had plenty of viewings and strong interest before
Consider a lower price if:
- the property had already been on the market for a long time
- the survey found a problem that the next buyer's survey will find too
If in doubt, go back on the market at the original price for a few weeks and see what interest you get.
Why house sales fall through
What to do: Treat an accepted offer as the start of the sale, not the end. Nothing is certain until contracts are exchanged.
House sales fall through because an accepted offer is not legally binding in England and Wales. An estate agent sale, known as a private treaty sale, is an informal tender process: buyers make offers, you accept one, and nothing is binding on either side. The buyer can withdraw or lower their offer at any time until contracts are exchanged. That can be months after you accepted the offer. Scotland has a different system, where offers become binding at an earlier stage.
This is true even if both sides have signed the contract and the buyer has sent a 10% deposit to their solicitor. The sale only becomes binding when the two solicitors formally exchange contracts.
How often sales fall through
Around one in three agreed sales fails to complete. That is the government's own figure, set out in its June 2026 reform roadmap, which also puts the cost of failed sales to consumers at around £400 million a year.
Around one in three sales agreed through an estate agent fall through. The figures are from the government's June 2026 reform roadmap.
The roadmap promises upfront sales packs and, in time, binding conditional contracts. Earlier ideas, such as the voluntary reservation agreements proposed in 2019, were never made compulsory. None of the new changes are law yet, so for now the process remains slow and uncertain for many sellers. Our article on the home buying and selling reforms explains what is planned.
With an estate agent, a sale can fall through at any point between the offer and exchange, often months later. At an unconditional auction, contracts are exchanged on auction day.
The eight most common reasons
A sale can collapse at any point before exchange, even months after you accepted the offer. These are the eight most common reasons. Where there is something you can do about it, we say what helps.
- Survey results. The buyer's survey finds a problem, such as structural movement or the need for major repairs, and the buyer withdraws or asks for a lower price.What helps: Tell buyers about known defects at the start. You have to answer the seller's property information form honestly in any case, and a defect that surfaces late is the most common cause of a lower offer.
- A broken chain. Most buyers need to sell their own home first. If one sale in the chain collapses, every sale that depends on it can stall.What helps: If you have more than one offer, weigh up each buyer's position. A first-time buyer, or a buyer with no chain, is often safer than a higher offer from a buyer in a long chain.
- Mortgage problems. The lender refuses the loan, or values the property at less than the agreed price.What helps: Before you accept an offer, ask your estate agent to get a copy of the buyer's mortgage agreement in principle.
- Slow conveyancing. Conveyancing is the legal work of transferring ownership. It has many stages, and long delays give buyers time to lose patience or change their plans.What helps: Choose an experienced conveyancer and ask for regular updates.
- A change in circumstances. Redundancy, relocation, illness or a relationship breakdown can force a buyer to withdraw, however keen they were.
- A change of mind. Buying a home is an emotional decision, and some buyers simply decide that the move is no longer right for them.
- Gazundering. This is when a buyer lowers their offer just before exchange, knowing that you are under pressure to accept. Some reductions are justified by a survey, and others are tactical.What helps: Decide the lowest price you will accept early on, and stay calm if it happens.
- Market conditions. Rising interest rates, or several similar homes coming up for sale nearby, can make buyers nervous or give them other choices.What helps: Review your price, or consider a different method of sale.
Why a late collapse costs so much time
With an estate agent sale, things often go wrong late. A sale can fall through after four or five months, and sometimes much longer. We regularly hear from sellers who spent up to a year tied into a sale that never completed.
There is a second cost. Once an offer is accepted, most estate agents stop marketing the property and tell other buyers it is sold. If the buyer then withdraws, you start again from the beginning. One way to soften this is to ask your agent to keep the listing live, marked "under offer". Agents have to pass on every offer they receive until contracts are exchanged, so a keen buyer can still come forward.
Estate agent sale vs auction sale: when the sale becomes binding
What to do: When you compare ways to sell, ask one question first: at what point is the buyer legally committed?
With an estate agent, accepting an offer and instructing solicitors is only the start. The buyer then arranges a survey, a mortgage and searches, and their solicitor raises legal enquiries. Until contracts are exchanged and the buyer pays their deposit, the buyer can withdraw or try to renegotiate the price.
At an unconditional auction, the order is reversed. Buyers view the property and read the auction legal pack before they bid. When the hammer falls, contracts are exchanged and the buyer pays a deposit, usually 10% of the price. From that moment the sale is legally binding. The buyer cannot reduce their offer or withdraw. A buyer who fails to complete is in breach of contract: they lose their deposit and can be sued for any further loss, which is why it very rarely happens. Completion usually follows 28 days later.
With an estate agent, the sale can fall through at any point until exchange. At auction, buyers finish their research before they bid, so the winning bidder is committed when the hammer falls.
Not every auction is binding on the day
Has your estate agent suggested auction? The route many estate agents offer is a conditional auction, often called the modern method of auction. It works differently. The winning bidder pays a reservation fee instead of exchanging contracts, then has a set period, usually 56 days, to exchange and complete. During that time the buyer can still walk away. They lose the fee, but the sale falls through all the same.
If certainty is your reason for considering auction, check that the sale is unconditional before you sign anything. The conditional route is not one we recommend. Our guide to unconditional and conditional auctions explains the difference.
How to spot a sale that is about to fall through
What to do: Ask your solicitor for a short update every week. Regular contact is the simplest way to catch a problem early.
A sale rarely collapses without warning. Spotting the signs early can save you weeks or months, and lets you move on to another buyer sooner.
Warning signs to watch for
- The buyer's solicitor has gone quiet, or is slow to reply to your solicitor.
- The buyer has not booked a survey, or keeps putting it off.
- The buyer's mortgage offer is taking much longer than expected.
- The buyer asks to change the price or the dates late in the sale.
- The buyer avoids questions about their own sale or their finances.
How to stay on top of the sale
- Stay in regular contact with your solicitor. Your estate agent can help, but your solicitor has the clearest view of the legal progress. If your solicitor has not heard from the buyer's solicitor for a while, treat it as a warning.
- Learn the stages of conveyancing. If you know what is meant to happen and when, you will notice when something is late, and you can ask the right questions.
- Ask to speak to the buyer. If the sale has stalled and you are not getting clear answers, ask your estate agent whether the buyer will talk to you directly. A short conversation can clear up a delay. A buyer who refuses may not be as committed as you hoped, and it may be time to look for another buyer.
Problems further along the chain
Sometimes the problem is not your buyer. Your buyer's own buyer may have pulled out, leaving your buyer trying to resell their home without telling anyone. Or your buyer's property may have a legal or structural problem that stops their buyer getting a mortgage.
If nobody tells you, you can wait for months for a sale that has little chance of completing. Ask your agent to check progress along the whole chain, not just your part of it.
How to protect your next estate agent sale
What to do: Before you accept the next offer, ask the buyer for proof of funds and find out whether they have a property to sell.
If you stay with an estate agent, it is natural to want a new buyer quickly. Try not to accept the first offer that comes along. Take a few days before you choose the next buyer, and think about what you would do differently this time.
The first list below is the basic process for choosing a buyer. The two lists after it are optional steps that can speed things up or add protection.
Choose the right buyer
- Check the buyer's finances. A good estate agent checks that a buyer is able to go ahead before recommending them. You can still ask for proof of funds, such as a bank statement for the deposit and a mortgage agreement in principle. If the buyer would rather not send these to you, your agent can pass them to your solicitor.
- Favour buyers with no chain. First-time buyers, cash buyers and buyers who have already sold are much less likely to run into delays. Between two offers, a chain-free buyer at a slightly lower price can be the safer and faster choice.
- Ask for a small deposit. Ask the buyer to pay a deposit (for example, £1,000 to £2,000) to your solicitor under a short written agreement. Your solicitor draws it up, and it says the deposit is forfeited if the buyer withdraws before an agreed exchange date. Without the written terms, a buyer can ask for the money back. It is not an unreasonable request: developers of new homes ask for reservation fees as a matter of course. A buyer who will not pay a modest deposit may not be fully committed.
Optional: keep the sale moving
- Encourage an early survey and searches. Most renegotiations and withdrawals follow the buyer's survey, and almost every survey finds something. It is better for any problem to come up early. A buyer who has already paid several hundred pounds for a survey and searches has also shown that they are serious.
- Agree deadlines. Set dates for the survey, the replies to legal enquiries and exchange. They do not have to be rigid, but they keep everyone focused.
- Check progress against those dates. If the buyer has been refused a mortgage more than once, or their solicitor is not replying, there may be trouble ahead.
- Use a group email. One email thread that includes both solicitors, the estate agent and, where appropriate, the buyer makes it harder for a query to go unanswered. A weekly update is enough.
Optional: extra protection
- Consider a reservation agreement. This is a written agreement between you and the buyer. For a set period, you agree not to accept any other offer, and the buyer agrees not to look at other properties. If either side pulls out during that period, they usually forfeit a sum of money. These agreements tend to favour buyers more than sellers, but they can give some reassurance.
- Consider a contract race. If you have more than one keen buyer, your solicitor can send a contract to each of them, and the first to exchange gets the property. Your solicitor will expect to tell every buyer that a race is on, so some may withdraw, and you may pay extra legal fees.
- Change estate agent. Did your agent chase the last sale and keep you informed? If not, you can switch to another agent. Check your agreement first: most have a minimum term, and you then have to give notice to end it. When you choose a new agent, ask whether they have a sales progressor. That is a member of staff whose only job is to push agreed sales through to completion.
- Keep your options open. Have a backup plan in case this sale does not work out either. Could you let the property instead, sell it at auction, or wait for a better time? The next section looks at the other ways to sell.
Other ways to sell after a failed sale
What to do: Ask yourself which matters most to you now: the highest price, a quick sale, or a sale that cannot fall through. Your answer tells you which method to choose.
Not every property suits an estate agent sale. Often it takes a failed sale to show this. If your home needs renovation, or has a legal or structural problem, another method of sale may give you a better result.
Sell at auction
At an unconditional auction, the sale becomes binding on the day the buyer is found. Contracts are exchanged when the hammer falls, the buyer pays a deposit, usually 10%, and completion usually follows 28 days later. A freehold sale typically takes 6 to 8 weeks in total, from instructing the auctioneer to completion.
Instead of relying on one buyer, auction puts your property in front of many buyers, who bid against each other.
Estate agent vs auction: a private treaty sale relies on a single buyer, whereas an auction puts the contract in front of many buyers at once.
Any property can be sold at auction. It suits homes that need modernising particularly well, and these often do better at auction than with an estate agent.
Auction is not a guarantee. If bidding does not reach your reserve price, which is the lowest price you have agreed to accept, the property stays unsold. Auction also usually costs a little more than an estate agent. Our pages on auction fees and the disadvantages of selling at auction cover both points.
For a home in good condition, an extended auction runs the bidding over several weeks instead of a few minutes. That gives buyers who need a mortgage time to take part, and the sale is still binding once a bid is accepted.
If your failed sale was through an estate agent, check your agreement with them before you instruct an auctioneer. It is also worth asking your solicitor whether the documents from that sale can be reused for the auction legal pack.
Sell to a cash buying company
If speed matters more than price, a reputable homebuyer company can buy your property directly for cash. There is no chain, the sale can complete in days or weeks, and a trade buyer is unlikely to be put off by a survey. The trade-off is price. A buying company needs to make a profit, so it will offer less than the open market value.
Take care, because not all companies work in the same way. Some are brokers, not buyers, and can waste your time. One warning sign is being asked to sign anything at all, even something that looks harmless, such as an "offer acceptance" form. A genuine direct buyer will not ask you to sign anything. The only documents to sign are those issued to you by your own solicitor.
Use a bridging loan to keep your purchase
A bridging loan is a short-term loan with a high rate of interest. It lets you go ahead with the purchase of your next home even though your sale has fallen through. You repay the loan when your property sells.
A bridging loan can stop a chain from collapsing, but the risk is significant. Interest and fees are high, and the cost keeps growing until your home sells. A bridging loan secured on your home is a regulated mortgage, so a broker or adviser has to assess whether it is suitable for you. Take independent financial advice before you consider one.
Wait, improve or let the property
If you are under no pressure to sell, you can pause. Improving the condition or presentation of the property may help it sell for more later.
You could also let the property while you wait, but letting is a longer commitment than it used to be. Since 1 May 2026, a landlord in England cannot use the "selling the property" ground for possession in the first 12 months of a new tenancy. The landlord must give four months' notice, and the notice cannot run out before those 12 months are up. You can sell with the tenant in place instead, which auction buyers are used to.
If you have a mortgage on the property, you will need your lender's consent before you let it. Most lenders will give consent to let for a set period, often 12 months, and some charge a fee or raise the interest rate. Letting without consent breaks the terms of your mortgage. If you own a leasehold flat, check the lease too: many leases require the freeholder's consent before you can let, and some do not allow short lets at all.
Summary: your options compared
| Option | When the sale becomes binding | Suits you if |
|---|---|---|
| Estate agent again | On exchange of contracts, often months after you accept an offer. | Price matters most and you can accept the risk of another delay. |
| Unconditional auction | On auction day, when the hammer falls. | You want the buyer committed on auction day, and completion about 28 days later. |
| Cash buying company | On exchange of contracts, which can be within days or weeks. | Speed matters more to you than price. |
| Bridging loan | It does not sell your home. It pays for your purchase while you find a buyer. | You cannot lose your purchase and can afford the cost. |
| Wait or let | There is no sale for now. | You are under no pressure to sell. |
Frequently asked questions
Around one in three sales agreed through an estate agent in England and Wales falls through before completion. That is the figure in the government's June 2026 home buying and selling reform roadmap, which estimates that failed sales cost consumers around £400 million a year.
A sale can fall through at any stage up to exchange of contracts. There are no official figures for each stage. The most common points are after the buyer's survey or mortgage valuation, and when another sale in the chain breaks down.
There is no official figure. If a sale is going to fall through, it is most likely to happen after the survey. That is when the buyer first learns about any defects, and may withdraw or ask for a lower price.
Very rarely. Once contracts are exchanged, the sale is legally binding on both sides. A buyer who fails to complete loses their deposit, usually 10% of the price, and can be sued for the seller's losses.
Usually not. Before contracts are exchanged, neither side owes the other anything, so each side pays its own costs. The exception is where you and the buyer signed a reservation agreement, or the buyer paid a non-refundable deposit. If you are out of pocket, ask your solicitor whether a reduced fee applies to the work done so far.
Most solicitors charge for the work they have done on a sale that does not complete, to cover their time and expenses. The charge is usually less than the full fee for a completed sale. Some solicitors offer a "no sale, no fee" service, so check your terms.
Normally not. Most estate agents work on a "no sale, no fee" basis, so nothing is due if the buyer withdraws. Check your agreement for a "ready, willing and able purchaser" clause, which can make the fee payable if you are the one who withdraws.
A mortgage offer for your next home usually stays valid for a set period, so you may have time to find another buyer. Mortgage offers usually last for three to six months, but each lender sets its own period. Ask your lender or broker for the expiry date, and whether it can be extended.
Gazundering is when a buyer lowers their offer shortly before contracts are exchanged, when the seller is under pressure to accept. It is legal in England and Wales, because the offer is not binding until exchange. It cannot happen after the hammer falls at an unconditional auction.
Yes. Check your estate agent agreement first, because you may need to give notice before you instruct an auctioneer. A freehold property can usually go to auction about four weeks after you instruct the auctioneer. Your solicitor may also be able to reuse documents from the failed sale for the legal pack.
Not after the hammer falls at an unconditional auction. Contracts are exchanged at that moment, and a buyer who fails to complete loses their deposit, usually 10%. At a conditional auction, often called the modern method of auction, the buyer can still walk away and loses only the reservation fee.
If you have been treated unfairly
If you think your estate agent has treated you unfairly, complain to the agent first. Every estate agent must belong to a redress scheme, either The Property Ombudsman or the Property Redress Scheme. If the agent does not resolve your complaint, the scheme can look at it free of charge.
For a problem with a buyer, Citizens Advice explains where you stand, or you can speak to your solicitor.
