An accepted offer can feel like the finish line. Until contracts are exchanged, a property sale can still fall through. A buyer might change their mind, struggle to secure a mortgage or discover something unexpected during a survey. There is also the risk of gazumping, where a seller accepts a higher offer from someone else after agreeing to sell to an earlier buyer.
Gazumping is usually discussed as a problem for buyers, but sellers have decisions to make too. A higher offer may look attractive, yet switching purchasers can introduce delays, additional costs and the possibility of losing a reliable sale. Understanding how gazumping works, and how to keep your transaction moving, can help you make better decisions when competing offers appear.

What is gazumping in property?
Gazumping happens when a seller has accepted an offer on their property but later accepts a higher bid from another buyer before contracts have been exchanged. The original purchaser loses the opportunity to buy the home, even if they have already spent money on surveys, mortgage arrangements or legal work.
In England and Wales, an accepted offer is not normally legally binding until exchange of contracts. This means sellers can consider further offers during that period, although accepting a new bid may damage relationships and disrupt the transaction. The position differs in Scotland, where the conveyancing process uses formal offers and concluding missives. Once missives are concluded, the agreement is generally legally binding.
Is gazumping legal in England and Wales?
Yes. Gazumping is legal in England and Wales because accepting an offer does not normally create a binding contract for the sale of a property. Estate agents also have obligations when further bids arrive. Under the Estate Agents Act 1979, agents must generally pass offers to the seller promptly and in writing until contracts are exchanged, unless the seller has given specific written instructions not to receive certain offers.
However, being legally permitted to accept a higher bid does not automatically make it the best financial decision. A new purchaser offering more money might have a longer chain, uncertain mortgage arrangements or conditions that make completion less likely. The figure on the offer is only one part of what makes a sale worthwhile.

Why gazumping can be risky for sellers
A larger offer can quickly lose its appeal if it comes with greater uncertainty. Before abandoning an agreed sale, consider what you may be giving up.
You could lose a buyer who is ready to proceed
An existing purchaser may already have a mortgage agreement in principle, appointed a solicitor and arranged a survey. Starting again with someone offering more money could mean repeating weeks of work without any guarantee of a better outcome.
A higher offer might not survive the mortgage valuation
Mortgage lenders assess the property independently before confirming how much they are prepared to lend. If the new offer exceeds the lender’s valuation, the buyer may need to contribute more money or renegotiate the price. An impressive bid is worth little if the purchaser cannot finance it.
Delays can affect your onward purchase
If you are buying another home, changing buyers can affect the entire chain. Your own seller may become unwilling to wait, particularly if other purchasers are interested in their property. Protecting the progress already made can sometimes be worth more than accepting a slightly higher price.

How to protect your property sale from gazumping-related disruption
Sellers cannot remove every risk from a property transaction, but they can reduce the opportunities for uncertainty to take hold.
Choose the strongest buyer, not simply the highest offer
A buyer’s position matters as much as the amount they propose. Ask your estate agent to establish how the purchase will be funded, whether the purchaser has a property to sell and how quickly they can proceed. A chain-free buyer with verified finances may offer a smoother route to completion than someone offering more but relying on several linked transactions.
Keep your paperwork ready before accepting an offer
Missing documents can slow down conveyancing and leave a transaction exposed for longer. Prepare your property information, planning permissions, building regulations certificates, guarantees and other relevant paperwork as early as possible. Your solicitor can explain which documents are needed for your particular home, including any additional requirements for leasehold properties.
Ask about taking the property off the market
Once you accept an offer, you can ask your estate agent to stop actively marketing the property and mark it as sold subject to contract. This may reduce the likelihood of new enquiries, although it does not prevent unsolicited offers or make the transaction legally binding.
Keep the conveyancing process moving
Long periods without progress create uncertainty for everyone involved. Instructing a solicitor early, responding promptly to enquiries and keeping communication open can help avoid unnecessary delays. Your estate agent can also liaise with the parties in the chain, identify emerging problems and help maintain momentum towards exchange.
Consider a reservation agreement
In some transactions, buyers and sellers may agree to a reservation arrangement setting out their commitment to proceed. Depending on its terms, it may include financial consequences if either party withdraws without an agreed reason. Such agreements are not standard in every property sale, and their enforceability depends on the wording and circumstances. Independent legal advice is important before signing.
What should you do if another buyer offers more?
If a higher bid arrives after you have accepted an offer, resist making a decision based on the price difference alone. Ask your estate agent to assess the new purchaser’s financial position, chain circumstances and proposed timescale. Compare those details with the progress already made by your existing buyer. You should also consider the costs of any delay, particularly if you have an onward purchase or a preferred moving date. A fresh offer can be attractive on paper while being less dependable in practice. Your estate agent should present the information fairly, but the decision to accept or reject the new offer remains yours.
A successful sale is about more than the asking price
Gazumping highlights an important truth about selling property: the highest offer is not always the one that gets you moved.
