Gazundering is when a buyer lowers their offer on a property after the seller has accepted it, usually late in the process and often just before exchange of contracts. It is legal in England and Wales, because an accepted offer is not legally binding until contracts are exchanged. It is the buyer-side counterpart of gazumping. There are no official UK statistics, but surveys by house-buying companies suggest roughly one in five to almost one in three sellers have experienced it. In June 2026 the government announced plans for binding agreements and fines for buyers who withdraw without a valid reason, but the reforms are not law and are not expected until around 2029.
What is gazundering?
Gazundering means a buyer reduces their offer after the seller has already accepted a higher one. The seller is then left to choose between taking less money and putting the property back on the market, often after the home has been taken off sale and an onward purchase is in progress.
Gazundering meaning in short: a last-minute price cut by a buyer after a deal has been agreed but before contracts are exchanged. People also call it price chipping or simply chipping, and the verb is to gazunder: “the buyer gazundered us a week before exchange”.
The word plays on gazumping. If gazumping is a seller accepting a higher offer from someone else, gazundering is the buyer pushing the price down, so “gazunder” echoes the idea of going under the agreed price. Separately, “gazunder” is an old slang word for a chamber pot, the thing that goes under the bed, which is why you may see that meaning in a dictionary.
What is the difference between gazundering and gazumping?
Gazumping is a seller raising the price by accepting a better offer, while gazundering is a buyer lowering the price after agreeing a deal. Both can happen at any point before exchange and both are legal in England and Wales.
| Gazumping | Gazundering | |
|---|---|---|
| Who does it | The seller | The buyer |
| What happens | The seller accepts a higher offer from someone else | The buyer lowers their agreed offer |
| More common when | The market is hot and demand is strong | The market is cooling and buyers have more choice |
| Who is hurt | The original buyer | The seller, and sometimes the whole chain |

When does gazundering happen?
Gazundering can happen at any point between an offer being accepted and contracts being exchanged, and it often comes late. It is especially common after the survey or mortgage valuation, when the buyer has new information. It can happen on the day exchange is planned.
In a 2023 House Buyer Bureau survey of 1,104 recent sellers, 33% of lowered offers were announced within a week of the planned exchange date, while 51% came more than two weeks before it. The longer a sale takes, the more chances a buyer has to reconsider, which is why speed matters.
Why do buyers gazunder?
Buyers gazunder for genuine reasons and for opportunistic ones. Surveys by property companies point to the same main causes:
- Survey problems. The most common reason given is that the survey finds issues, such as damp, roof or electrical problems. In an Open Property Group survey published in 2024, 35% of gazundering buyers cited this.
- A down valuation. The mortgage valuation comes in below the agreed price, and the buyer cannot or will not make up the difference.
- Chancing it. Some buyers simply try to secure a discount, which 22% to 24% of sellers said in two separate surveys.
- A falling market. Prices dip between offer and exchange, and the buyer feels they overpaid.
- Their own chain. The buyer’s own sale is gazundered, so they can afford less for your home.
- A change in finances. Income, mortgage terms or affordability shift after the offer.
Whether reducing an offer after a survey counts as gazundering is debated. Many people see a reasonable, evidence-backed renegotiation as fair, and reserve the word for last-minute tactics with no good reason.
How common is gazundering in the UK? (gazundering statistics)
There are no official UK statistics on gazundering, so the best available figures come from surveys and data published by house-buying companies and consultancies. They suggest it is common, but they vary by sample, definition and market conditions.
| Source and date | Finding |
|---|---|
| House Buyer Bureau survey of 1,104 sellers, February 2023 | 31% of recent sellers had been gazundered. 75% accepted the lower offer. Of those who refused, 21% said the sale collapsed. |
| House Buyer Bureau follow-up survey, late 2023 | One in five sellers had been gazundered in the previous six months. |
| Open Property Group survey of 1,001 sellers, February 2024 | 25% of sellers who sold in the last 12 months had been gazundered. 35% of buyers cited survey issues and 24% were said to be chancing it. |
| Quick Move Now, November and December 2023 | 39% of its sales in November and 25% in December were subject to gazundering, up from 13% in October. |
| Quick Move Now, reported February 2025 | 19% of sales experienced an attempted renegotiation after a sale was agreed. |
These numbers should be treated with care. The surveys were commissioned or published by companies that buy houses or sell related services. Samples are fairly small, the question wording differs, and some figures include renegotiation after a survey. Gazundering tends to rise in cooling markets and fall when conditions stabilise.
Two more details are worth knowing. Quick Move Now’s data suggests more than half of attempts succeed in winning a lower price, while just over a quarter are rejected and the sale still completes. It also reported that some sales where the seller refused fell through entirely.
Is gazundering legal?
Yes. Gazundering is legal in England and Wales. Until contracts are exchanged, a sale is only subject to contract, and GOV.UK guidance says a verbal agreement between buyer and seller is not legally binding. That is why a buyer can lower their offer at any point before exchange, just as a seller can accept a higher one.
It is much less common in Scotland, where offers become legally binding earlier. Once the solicitors have concluded their exchange of letters, known as missives, a party who withdraws can be liable for the other side’s losses.
Is gazundering fair?
It depends on the reason. If a survey finds a real defect, or prices have fallen sharply, a buyer reducing their offer may be reasonable. If the buyer made a strong offer to win the property and cut it at the last minute because the seller is under pressure, most people consider it unfair, even though it is legal. The HomeOwners Alliance says buyers who gazunder often do so because they know the seller is in a weaker position, as their home has been taken off the market and they may be in a chain.
Gazundering is not risk free for buyers either. If a buyer tries it and fails, they can lose the money they have spent on surveys and legal fees, and the seller may find another buyer.
What should you do if you are gazundered?
The right response depends on why the buyer has lowered their offer and how much the sale matters to you. The main options are:
- Refuse. Hold the agreed price. The buyer may back down, or the sale may fall through and you will need to start again.
- Negotiate. Meet in the middle. This can work well if the buyer has a genuine reason, such as repairs found in the survey.
- Offer to fix the problem. If the issue is repairs, you could do the work or agree a reduction tied to evidence and quotes.
- Accept. If the lower price is still above the minimum you would take, accepting may be the quickest route to completion.
- Accept with conditions. Agree to the lower price only if the buyer exchanges and completes by a set date.
Before you decide:
- Ask why. Ask for the survey report, valuation or repair quotes.
- Know your bottom line. Work out the lowest price you can accept, especially if you have an onward purchase.
- Compare the cost of walking away. Include extra marketing time, mortgage payments and the risk of a chain collapsing.
- Keep your home marketed. A seller with other interested buyers is in a stronger position.

How can sellers reduce the risk of gazundering?
You cannot stop a buyer from lowering their offer, but you can reduce the risk and the leverage they have. The most effective steps are:
- Price realistically. An overpriced home is more likely to be renegotiated after the survey or valuation.
- Prepare paperwork early. Have your legal forms and searches ready before you list, to speed up the process.
- Move fast. Instruct a solicitor early, answer queries quickly and agree a target date for exchange.
- Be honest about problems. A survey will find them anyway, and hidden issues are a common trigger.
- Fix or disclose known issues before you market the property.
- Prefer simpler buyers. Chain free buyers, cash buyers and first-time buyers often move faster and have fewer reasons to renegotiate. Read our guide to what chain free means in property.
- Keep marketing. Taking the property off sale removes your fallback.
- Be wary of offers that look too good. An unrealistic offer may later be cut.
- Choose an experienced agent who can manage buyers and keep the sale on track.
Home sellers protection insurance can cover some legal costs if a sale falls through.
What can buyers do if they want to renegotiate fairly?
If you are a buyer and need to renegotiate, do it early, with evidence and in good faith. Raise concerns as soon as you have the survey or valuation, share the report and repair quotes, and propose a specific reduction or repair. Last-minute demands without a clear reason can cost you the property, the money you have spent and your relationship with the seller.
Will the government’s reforms stop gazundering?
The government says its reforms are designed to stop it, but they are not yet law. In June 2026 the Ministry of Housing, Communities and Local Government announced plans for legally binding agreements that would stop buyers walking away at the last minute without a valid reason, with fines for those who do. The same reforms target gazumping.
The timetable is not fixed, and legislation is expected by the end of this Parliament, around 2029. Until then, current rules apply and a buyer can still lower their offer before exchange. A binding agreement would still allow genuine reasons, such as serious survey problems, so renegotiation after a survey could remain possible.
