Homebuyers across the United Kingdom are incurring significant additional financial burdens due to the frequent collapse of property chains, with new research from Barclays revealing an average extra cost of approximately £2,000 per affected transaction. The bank's comprehensive analysis, which combines proprietary mortgage data with a survey of 2,000 individuals conducted by Opinium Research in January and February, highlights the acute stresses and monetary losses plaguing the residential property market.
Widespread Chain Disruptions and Financial Impact
The survey findings indicate that nearly one-third (32%) of people involved in a home purchase or sale over the past three years were part of a property chain. Within this group, a substantial 46% encountered either severe delays or complete transaction breakdowns directly linked to chain-related complications. Those impacted by these issues reported spending an additional £2,127 on average, often covering wasted survey fees or escalated solicitor costs resulting from prolonged and ultimately fruitless processes.
Gazumping and Gazundering Tactics
Among respondents whose property transactions ultimately fell through, several cited being "gazumped"—a practice where a seller accepts a higher offer from a new buyer at the eleventh hour, leaving the original purchaser stranded. Conversely, others experienced "gazundering," where buyers lower their offer at the last minute, causing the sale to collapse. Intriguingly, some participants admitted to attempting one of these tactics themselves, which subsequently led to the transaction's failure.
Market Context and Expert Insights
Barclays' mortgage data underscores the substantial financial commitments involved, showing the average UK deposit last month stood at £59,057, with first-time buyers facing a slightly higher figure of £62,272. Jatin Patel, head of mortgages, savings and insurance at Barclays, commented: "Movers often face battles on two fronts as the abundance of long property chains adds acute stress into the process."
Julien Lafargue, chief market strategist at Barclays, added: "In addition to frictions in the process, the UK housing market has also to contend with a mixed macroeconomic picture. Growth slowed in the second half of 2025 and the UK labour market is still softening. That said, the consumer remains broadly resilient, suggesting that growth could rebound in 2026."
Lengthening Transaction Times and Buyer Frustration
David Fell, lead analyst at Hamptons, provided further context, noting: "Lengthening transaction times are creating particular frustration for buyers. They are often receiving information about the property much later in the process than they would have a few years ago, by which point more time and money have already been invested."
Fell elaborated: "As the process drags on, it is more often the buyers—rather than sellers—who choose to pull out. This is usually due to issues raised in surveys and searches, or simply exhaustion with delays. By the time a sale collapses, the sunk costs can be substantial. Consequently, many sellers are choosing to withdraw from the market entirely rather than relist."
The research paints a challenging picture for the UK housing sector, where property chain instability not only imposes direct financial costs but also contributes to broader market inefficiencies and participant disillusionment.
