Gazumping happens when a seller accepts an offer on their property but then accepts a higher or more attractive offer from another buyer before contracts are exchanged.
For buyers, it can be particularly frustrating because it may happen after you have already spent money on surveys, searches, mortgage arrangements and legal work. Unfortunately, in England and Wales an accepted property offer is not normally legally binding until exchange of contracts.
That means gazumping is generally legal, even when the original buyer has already begun the conveyancing process.
If it happens to you, your main options are to improve your offer, strengthen your position without necessarily increasing the price, ask the seller to continue with you, or walk away.
What Is Gazumping?
Gazumping occurs when a seller has already accepted your offer but subsequently decides to proceed with another buyer.
The new offer may simply be for more money, but price is not always the deciding factor.
A seller could prefer another buyer because they:
- Are chain-free.
- Are a cash buyer.
- Already have a buyer for their own property.
- Can complete more quickly.
- Have stronger mortgage arrangements.
- Can accommodate the seller’s preferred moving date.
- Appear less likely to withdraw.
This means you can technically be gazumped even when the competing buyer has not offered substantially more money.
The important factor is that the seller changes their preferred buyer before contracts are exchanged.
At What Point Can You Be Gazumped?
You can potentially be gazumped at any point between having your offer accepted and exchanging contracts.
This can include after:
- Your offer has been accepted.
- The property has been marked Sold Subject to Contract.
- You have instructed a solicitor.
- The memorandum of sale has been issued.
- Searches have been ordered.
- You have paid for a survey.
- Your mortgage application has progressed.
- Your solicitor has raised enquiries.
A property transaction can therefore be quite advanced without being legally binding.
Understanding what happens after your offer on a house is accepted can help you see where the risk of gazumping fits into the wider buying process.
Is Gazumping Legal?
Yes. Gazumping is generally legal in England and Wales.
An accepted offer does not normally create a legally binding agreement to buy and sell the property.
The position changes when contracts are exchanged.
Until exchange, either party can normally decide not to proceed. A seller can therefore withdraw from the existing transaction and accept another offer.
This does not necessarily make gazumping fair or reasonable from the original buyer’s perspective, but there is an important distinction between conduct that may feel unfair and conduct that breaches a legally binding property contract.
Why Isn’t an Accepted Offer Legally Binding?
Buying a property involves much more than agreeing a price.
Before becoming legally committed, the buyer needs an opportunity to investigate matters including:
- The property’s legal title.
- Property searches.
- Rights and restrictions.
- Mortgage arrangements.
- Survey results.
- Fixtures and fittings.
- Leasehold information where applicable.
- Replies to legal enquiries.
This investigation takes place through the conveyancing process.
Until that work has been completed and contracts are exchanged, there is normally no binding agreement requiring the buyer to buy or the seller to sell.
The flexibility protects buyers as well as sellers. A buyer can also withdraw before exchange if, for example, a survey uncovers a serious structural problem.
Is Gazumping the Same as a Property Being Sold Subject to Contract?
No, although the two are closely connected.
When a property is marked Sold Subject to Contract, or SSTC, it normally means an offer has been accepted but contracts have not yet been exchanged.
The property therefore has an intended buyer, but the transaction remains non-binding.
This is the period during which gazumping can happen.
A Sold STC sign or online listing does not give the buyer ownership of the property or guarantee that the seller will eventually complete the transaction with them.
Can an Estate Agent Pass Another Offer to the Seller?
Yes.
An estate agent must pass offers received for the property to the seller until contracts are exchanged.
This remains the case even where the seller has previously accepted your offer.
Asking for the property to be removed from active marketing can reduce exposure to other buyers, but it cannot provide the same certainty as exchange of contracts.
An unsolicited offer could still be made.
What Should You Do If You Are Gazumped?
Finding out that another buyer has made an offer can create pressure to make a quick decision.
We recommend finding out what you reasonably can before reacting.
Confirm the Position
Ask the estate agent to confirm that another offer has been received and whether the seller intends to proceed with the new buyer unless you improve your position.
The agent may not be able to disclose confidential information about the other buyer.
What matters is establishing whether the seller is genuinely reconsidering the sale and what you would need to do to remain their preferred buyer.
Find Out Whether Price Is the Main Issue
Do not immediately assume you must offer substantially more money.
The seller may have been attracted by another aspect of the competing buyer’s position.
For example, the other buyer may:
- Have no property to sell.
- Already have their mortgage arranged.
- Be prepared to complete sooner.
- Be more flexible over the moving date.
- Have a shorter property chain.
If you can address the seller’s concerns without increasing your offer, you may still be able to keep the purchase together.
Decide Your Maximum Price
Before increasing your offer, decide what the property is genuinely worth to you.
Do not allow the fear of losing a property to push you substantially beyond:
- Your available budget.
- Your mortgage affordability.
- The property’s realistic value.
- What you are comfortable paying.
Remember that your mortgage lender will form its own view of the property’s value.
Offering significantly more does not automatically mean a lender will agree to lend more.
Speak to Your Solicitor
If you have already instructed us or another solicitor, explain what has happened.
The transaction may already involve searches, enquiries or other legal work.
Your solicitor can explain the position of the legal work already completed and what happens if the transaction stops.
Consider Whether You Actually Want to Continue
Being gazumped can make buyers more determined to secure a property simply because someone else wants it.
That is not always a good reason to pay more.
Ask yourself whether you would still consider the property good value at the revised price if no competing buyer existed.
If the answer is no, walking away may be the better decision.
Should You Make a Higher Counter-Offer?
You can increase your offer if the property remains worth the additional amount to you and you can afford it.
However, there is no guarantee the seller will accept your revised offer.
For example:
| Option | Possible Advantage | Main Risk |
|---|---|---|
| Match the competing offer | May keep you in the transaction | You pay more than originally planned |
| Beat the competing offer | Could make your offer more attractive | Can start a bidding contest |
| Keep the same price but strengthen your position | Avoids increasing the purchase price | Seller may still prefer the higher bid |
| Walk away | Protects your budget | You lose the property and some costs already incurred |
Before increasing your offer, consider the full cost rather than focusing only on the difference in purchase price.
An extra £5,000 or £10,000 is still real money even when viewed alongside the overall price of a property.
Can You Make Your Offer Stronger Without Increasing the Price?
Yes.
Price is important, but certainty can also matter to a seller.
You may be able to strengthen your position by demonstrating that you are ready to proceed.
For example, you could confirm that:
- Your solicitor is already instructed.
- Your mortgage application is progressing.
- Your deposit is available.
- Searches have already been ordered.
- Your survey has been arranged.
- You are chain-free, if applicable.
- Your own property is already under offer, if applicable.
- You can accommodate the seller’s preferred completion date.
The legal work involved in buying a property can progress more smoothly when buyers provide documents and respond to requests promptly.
A seller comparing two similar offers may prefer the buyer who appears more likely to reach exchange without delay.
Can You Ask the Seller to Honour the Original Offer?
Yes. There is nothing wrong with asking the estate agent to present your position clearly to the seller.
The seller may have accepted your offer for reasons beyond price.
If you have already progressed the transaction considerably, you can point out that:
- Your solicitor is already working on the purchase.
- Searches may already be underway.
- Your mortgage is progressing.
- You have invested time and money in the transaction.
- You remain committed to proceeding quickly.
A new buyer will generally need to start much of this process from the beginning.
That could make your existing transaction more attractive despite a slightly higher competing offer.
Can You Ask for Evidence of the Other Offer?
You can ask the estate agent for clarification about the competing offer.
However, you should not expect access to another buyer’s confidential information or financial details.
Rather than becoming focused on obtaining paperwork belonging to the other buyer, concentrate on the information relevant to your own decision:
- Has another offer genuinely been made?
- Has the seller accepted it?
- Is the seller giving you an opportunity to respond?
- Is the issue purely the price?
- Would improving another part of your position make a difference?
You can then decide what you are prepared to do.
Can Estate Agents Invent Offers to Increase the Price?
Estate agents must deal with offers appropriately and pass them to the seller.
If you have concerns about how an offer is being handled, ask clear questions and keep a record of important communications.
We would not recommend assuming that a competing offer is false simply because it arrives after your offer has been accepted.
Make your decision based on your own budget, valuation of the property and willingness to proceed rather than allowing yourself to be pressured into an open-ended bidding contest.
What Happens to the Money You Have Already Spent?
One of the most frustrating consequences of gazumping is that buyers may have already incurred substantial transaction costs.
Potential losses can include:
- Survey fees.
- Search fees.
- Mortgage-related costs.
- Legal work already completed.
- Specialist property reports.
Because the purchase has not yet become legally binding, these costs cannot normally simply be claimed from the seller because they choose another buyer.
Your exact position will depend on the circumstances and any agreements or insurance you have in place.
Can Home Buyer Protection Insurance Help?
Specialist home buyer protection insurance may provide cover for certain costs when a property purchase falls through for a reason covered by the policy.
Depending on the policy, this might include some legal, survey, valuation or mortgage-related costs.
However, cover varies considerably.
Before relying on a policy, check:
- Whether gazumping is covered.
- The maximum amount that can be claimed.
- When the policy must be purchased.
- Which expenses qualify.
- Exclusions.
- Evidence required to make a claim.
Insurance does not prevent gazumping. Its purpose is to reduce some of the financial impact if a qualifying purchase falls through.
What Is a Lockout Agreement?
A lockout agreement, sometimes called an exclusivity agreement, can give a buyer a period in which the seller agrees not to negotiate with another potential buyer.
For example, the agreement might provide an exclusivity period of 14 or 28 days.
This gives the buyer time to progress the transaction without the seller actively negotiating with somebody else.
However, a lockout agreement does not normally require the seller to complete the property sale.
Its purpose is generally to restrict dealings with other buyers for an agreed period.
The wording and legal effect of an exclusivity agreement matter, so legal advice should be taken before relying on one.
How Can You Reduce the Risk of Being Gazumped?
There is no method that completely removes the risk before exchange, but you can make the transaction more secure by reaching exchange efficiently.
Instruct Your Solicitor Early
You do not want to lose the first week of the transaction looking for a solicitor after your offer has already been accepted.
Having your solicitor ready means the legal process can start as soon as the relevant information arrives.
Have Your Mortgage Arrangements Ready
If you need a mortgage, obtaining an Agreement in Principle before making an offer can demonstrate that you have already considered your borrowing position.
Once your offer is accepted, progress the full application promptly.
Provide Proof of Funds Promptly
Do not leave requests for identification, deposit evidence or source-of-funds documentation unanswered.
Delays at the beginning of the transaction can give a seller doubts about how quickly you will be able to proceed.
Ask for the Property to Be Taken Off the Market
When your offer is accepted, ask the seller to stop actively marketing the property and conducting further viewings.
They do not have to agree.
Even if they do, another buyer may still make an unsolicited offer and that offer may still need to be passed to the seller.
However, removing the property from active marketing can reduce opportunities for competing buyers to emerge.
Arrange Your Survey Promptly
Do not leave the survey until the last possible moment.
An early survey gives you more time to investigate problems and prevents the transaction sitting unnecessarily without progress.
Respond Quickly
Property transactions involve repeated requests for documents, signatures and decisions.
Responding promptly to your solicitor, lender and other professionals helps demonstrate that you are a committed buyer.
Consider a Lockout Agreement
Where the circumstances justify it, you can ask whether the seller is prepared to enter into an exclusivity agreement.
This may be particularly worth discussing where significant costs need to be incurred early in the transaction.
Consider Protection for Abortive Costs
If you are concerned about losing money if the purchase falls through, investigate whether suitable buyer protection insurance is available before incurring substantial costs.
Check the terms carefully rather than assuming every failed purchase will be covered.
Does a Memorandum of Sale Protect You From Gazumping?
No.
A memorandum of sale confirms the basic details of an agreed property transaction and allows the solicitors to begin their work.
It does not normally make the sale legally binding.
Our explanation of the memorandum of sale process covers what this document contains and what happens once it has been issued.
Even after a memorandum of sale has been circulated, gazumping remains possible until contracts are exchanged.
Does Marking a Property Sold STC Prevent Gazumping?
No.
Sold Subject to Contract tells potential buyers that the seller has accepted an offer.
It can discourage further interest, particularly if the property is removed from active advertising and no more viewings take place.
However, SSTC is not the same as a binding contract.
The crucial legal milestone remains exchange.
When Does the Risk of Gazumping End?
The normal risk of gazumping ends when contracts are exchanged.
At exchange, the buyer and seller become legally committed to the transaction.
Withdrawing after exchange can have significant contractual and financial consequences.
This is why progressing efficiently towards exchange is one of the best practical ways of reducing the period in which gazumping can occur.
Gazumping vs Gazundering: What Is the Difference?
Although the terms sound similar, they describe opposite situations.
| Term | What Happens | Who Changes the Deal? |
|---|---|---|
| Gazumping | A seller accepts another buyer’s better offer before exchange | Seller |
| Gazundering | A buyer reduces their offer shortly before exchange | Buyer |
Neither should be confused with ordinary negotiations following a genuine change in circumstances.
For example, reducing an offer because a survey discovers a previously unknown major structural defect is different from simply lowering the price at the last moment to put pressure on a seller.
What If You Are a First-Time Buyer?
First-time buyers can be particularly concerned about gazumping because they may not have experienced the conveyancing process before.
However, being a first-time buyer can also make your offer attractive.
You will normally have no property to sell, meaning there is no transaction below you in the chain.
If a competing offer appears, make sure the seller understands the strengths of your position rather than assuming the only response is to increase the price.
Should You Walk Away If You Are Gazumped?
Sometimes, yes.
Walking away can be disappointing, particularly after you have invested time and money in the purchase.
However, a house is still a financial decision.
We would be cautious about allowing frustration or competition with another buyer to persuade you to pay more than you can afford or more than you believe the property is worth.
Before increasing your offer, ask:
- Can we genuinely afford the higher price?
- Will the mortgage still work?
- Does the property justify the new figure?
- Are we bidding because of the property’s value or because we do not want to lose?
- Would we regret paying the increased amount after moving in?
Having a firm maximum figure can make this decision much easier.
Gazumping When Buying a Property in Reading
Gazumping rules are not different simply because you are buying in Reading, but local buyers still benefit from progressing the legal work promptly and understanding where they stand before exchange.
Our conveyancing solicitors in Reading help buyers through the property process from an accepted offer through searches, enquiries, exchange and completion.
If another offer appears during the transaction, we can explain where the legal work has reached and what the practical implications are if you decide to continue or withdraw.
What Should You Do if Another Buyer Makes a Higher Offer?
Do not panic and do not immediately start bidding against yourself.
First establish what has happened.
Then:
- Confirm the seller is genuinely considering the other offer.
- Find out whether price is the only factor.
- Review your mortgage and available budget.
- Decide the maximum you are prepared to pay.
- Make the strongest offer you are comfortable with.
- Highlight any advantages in your buying position.
- Ask for a clear decision from the seller.
- Be prepared to walk away if the figures no longer make sense.
There is nothing wrong with increasing your offer when the property remains good value to you.
Equally, there is nothing wrong with deciding that another buyer is prepared to pay more than you are.
Frequently Asked Questions
Can you sue a seller for gazumping you?
Usually, an accepted offer in England and Wales is not legally binding before exchange of contracts, so a buyer cannot normally require the seller to complete simply because their earlier offer was accepted. Different circumstances can arise where a separate contractual agreement exists, so specific legal advice may be necessary.
Can you be gazumped after a survey?
Yes. A survey being completed does not make the purchase legally binding. You remain at risk until contracts are exchanged.
Can you be gazumped after receiving a mortgage offer?
Yes. A formal mortgage offer confirms the lender’s willingness to lend subject to its terms, but it does not bind the seller to the property transaction.
Can you be gazumped after searches have been completed?
Yes. Searches are part of the buyer’s legal investigation and do not prevent the seller from accepting another offer before exchange.
Can you be gazumped after signing the contract?
Potentially. Signing your copy of the contract is not necessarily the same as exchanging contracts. The key point is whether exchange has actually taken place.
Does the seller have to accept the highest offer?
No. Sellers can consider factors other than price when choosing a buyer. Certainty, chain position, timescale and flexibility may all influence the decision.
Does a seller have to stop viewings after accepting an offer?
No. You can ask the seller to stop viewings and remove the property from active marketing, but they do not have to agree before exchange.
Can a cash buyer gazump someone with a mortgage?
Yes. A seller may consider a cash buyer attractive because there is no mortgage application involved, but being a cash buyer does not automatically guarantee a faster or safer transaction.
How quickly should you respond to a gazumping situation?
You should establish the facts and make your decision promptly, but that does not mean making an unaffordable offer under pressure. Work out your maximum position first.
What is the best protection against gazumping?
Exchange of contracts provides the key legal certainty. Before then, progressing the transaction efficiently, asking for the property to be removed from active marketing, considering an exclusivity agreement and protecting abortive costs where appropriate can all help reduce the risk or financial impact.
Our Final Thoughts
Gazumping is possible because an accepted property offer in England and Wales does not normally become legally binding until contracts are exchanged.
If another buyer appears, you do not automatically need to offer more. Find out what matters to the seller, demonstrate the strength of your own position and decide what the property is genuinely worth to you.
The best practical defence is preparation. Have your finances ready, instruct your solicitor quickly, respond to requests without unnecessary delay and aim to move towards exchange efficiently.
If you are buying a property and need help with the legal process, we can guide you from the accepted offer through to exchange and completion, explain any issues that arise and help you understand your options if the transaction changes unexpectedly.
