Buyer Cut Her Offer by £15,000 a Day Before Exchange. It's Called Gazundering, and England's Legal System Allows It

A woman identified only as Sarah was a day away from exchanging contracts on her three-bedroom terraced house when her estate agent called with bad news. Her buyers had decided, at the last minute, that they wanted to pay £15,000 less than the price everyone had already agreed to, according to the BBC.

Sarah and her husband were mid-move. They'd sold their renovated terrace to buy her parents' four-bedroom house in the countryside, a chain that depended on everything closing on schedule. She'd already paid legal fees once. She'd already paid removal fees. A collapsed sale meant paying both again, on top of losing £15,000 if she caved.

"It was awful, your heart just drops to your stomach," Sarah told the BBC.

This has a name: gazundering. A buyer waits until the seller is fully committed, financially and emotionally, then drops the price knowing the seller has too much to lose by walking away. It's legal in England and Wales for one simple reason: an accepted offer isn't binding until contracts exchange. Right up until that moment, either side can walk, or in this case, renegotiate under duress.

Why the system allows it

In England and Wales, the average house sale takes 120 days from accepted offer to completion, according to the Ministry for Housing, Communities and Local Government. During that entire window, there's no contract. One in three sales collapses before exchange, the same government data shows.

That failure rate isn't free. The Ministry for Housing, Communities and Local Government estimates collapsed sales cost sellers £400 million a year and the broader economy £1.5 billion. Some of those collapses are gazundering. Others are buyers finding a better house, mortgage offers falling through, or surveys turning up problems. The system doesn't distinguish between honest cold feet and a calculated squeeze play, because it wasn't built to.

Beth Rudolf of the Conveyancing Association told the BBC gazundering is "a small but growing problem," not yet common but increasing. That's a real distinction worth holding onto: this is not an epidemic. It's a structural vulnerability that a minority of buyers are learning to exploit, and the frequency is rising.

Sarah called the bluff

Sarah's story actually cuts against the doom-and-gloom framing a little. She didn't fold. After talking with her father and husband, she put the house back on the market that same day rather than accept the lower price.

Her buyers blinked first. The next day, according to the BBC, they went back to the estate agent and agreed to pay the originally agreed price after all. Sarah got her sale, at her number, because she was willing to walk.

It's one family with the financial cushion and nerve to call a bluff. Plenty of sellers don't have that luxury, especially first-time sellers stretched thin by a chain, or people relying on the sale to fund care costs, a divorce settlement, or a job relocation. For them, £15,000 knocked off at the eleventh hour isn't a negotiating tactic to shrug off. It's a forced loss.

The fix everyone agrees on, nobody's rushing

The government's own reform package would reportedly cut the sale-to-completion window by four weeks and save the average first-time buyer £650, according to the Ministry for Housing, Communities and Local Government. Shorter timelines mean less time for a buyer to get cold feet, shop around, or decide to squeeze the seller. Less time between offer and exchange is fewer opportunities for gazundering to even happen.

The reforms are reportedly not scheduled to arrive until 2029. The Conveyancing Association is asking the government to bring them in "without delay," arguing there's no good reason a known, quantified problem should sit on the shelf for three more years while it gets worse.

A £1.5 billion annual economic drag and a documented, growing exploit aren't the kind of thing that typically benefits from waiting. The counterargument, unstated in the government's own materials but implicit in any large bureaucratic timeline, is that conveyancing reform touches legal processes, land registry systems, and professional bodies that don't move fast by design. Whether that justifies a four-year wait on a fix everyone already agrees is needed is the open question Sarah's story leaves on the table.

No legislation has been introduced yet to accelerate the timeline. Until something changes, every seller in England and Wales remains exposed to the same 120-day window Sarah was in. Nothing is final until exchange, no matter what's been agreed.
