Gazundering: buyers cut £15,000 the day before exchange

Gazundering is when a buyer lowers an agreed offer just before contracts exchange. A seller known as Sarah saw buyers cut £15,000 the day before exchange, per BBC nees coverage. In England and Wales, offers are not binding until exchange, so sellers face pressure to accept less or risk the chain collapsing.

Sarah, not her real name, was packing to leave a renovated three-bedroom terrace for her parents' four-bedroom countryside home when her estate agent called with bad news. The buyers said further research on the area meant they would now pay £15,000 less. "It was awful, your heart just drops to your stomach," she told the BBC.

Key Takeaways

• Gazundering means a last-minute cut to an agreed offer before exchange of contracts.
• Offers in England, Wales and Northern Ireland are not legally binding until exchange.
• Failed sales cost sellers about £400m a year, the housing ministry says.
• Reservation agreements and early conveyancing paperwork can reduce gazundering risk.
• Planned reforms aim for legally binding agreements, but the timetable runs to 2029.

What is gazundering and why does it hurt sellers?

Gazundering is when a buyer lowers their agreed offer just before contracts are exchanged. The seller must accept less or risk losing the sale and collapsing the chain—and possibly the home they hope to buy.

It is possible because an offer is not legally binding until exchange. Completion takes an average of 120 days after an offer is accepted, and one in three house sales fall through before exchange.

That fallout costs sellers £400m and the wider economy £1.5bn each year, according to the Ministry for Housing, Communities and Local Government. More on similar market pressure sits in our Luxury Real Estate & Dream Homes coverage.

Why is gazundering rising in England and Wales?

Beth Rudolf of the Conveyancing Association says gazundering remains uncommon but is growing as the market turns toward buyers. More homes for sale than buyers means sellers face stiffer competition and pressure to cut prices.

Sarah re-listed the same day rather than accept the cut. The next day the buyers returned, ready to proceed at the original price. She still called the tactic awful: "It's my children's home and the fact that nothing's been done about it is ridiculous."

The association wants reforms "without delay" instead of waiting until 2029. The ministry told the BBC it is introducing legally binding agreements to stop last-minute walkaways without a valid reason, with fines for those who do. Planned reforms would also cut transaction time by four weeks and save the average first-time buyer £650.

How can sellers avoid gazundering before exchange?

Tell your estate agent your finances cannot absorb last-minute renegotiation, so buyers hear that boundary early. Instruct conveyancers to gather Land Registry, local authority, drainage, water and environmental searches—and property information questionnaires—when you list, shrinking the window for pressure.

Consider a reservation agreement: the buyer pays a fee to reserve the property for a set period, both sides face penalties if they pull out, and the seller agrees not to sell elsewhere. A conditional binding offer can also lock in a purchase subject to rules such as a related sale or mortgage, with a clean exit if those conditions fail.

Speed matters too. Long gaps between offer and exchange give buyers more room to reprice, a point stressed in debate pieces that treat gazundering as risk management in a buyers' market rather than pure bad faith.
