Collapsed property transactions may be falling but they continue to drain more than £1bn a year from the UK housing market and shining a light on the ongoing fragility of deal progression.
The latest Fall-Through Index from House Buyer Bureau shows that 61,488 sales fell through in Q4 2025 – down 25.1% on the previous quarter and 12.9% lower year-on-year.
Despite the reduction in volumes, the financial impact remains substantial. The total cost of failed transactions hit £218.3m in the final three months of the year, taking the full-year total to just over £1bn.
The figures highlight a persistent structural issue within the housing transaction process, with delays, uncertainty and buyer caution continuing to derail deals even as activity levels fluctuate.
FALL-THROUGH COSTS RISING
On an individual level, the cost of a fall-through is also rising. The average failed transaction cost reached £3,550 in Q4, up 0.3% on the quarter and 3.4% higher than a year earlier.
While the overall quarterly cost has eased due to fewer collapses, the scale of losses remains significant – particularly in a market already dealing with affordability pressures and economic volatility.
The data reinforces the growing importance of certainty in the sales process, with sellers increasingly weighing the risk of a deal collapsing against the potential to achieve a higher price.
COSTLY ISSUE
Chris Hodgkinson (main picture, inset), Managing Director of House Buyer Bureau, says: “Whilst it’s encouraging to see a notable reduction in the number of fall-throughs, the reality is that they remain a significant and costly issue for sellers, both financially and emotionally.
“Even with volumes down, over £218m lost in a single quarter underlines just how disruptive collapsed transactions continue to be, with a huge £1bn lost annually.”
PRONOUNCED RISK
And he adds: “For many sellers, a fall-through doesn’t just mean additional legal and administrative costs, it often results in lost time, missed onward purchases and the need to re-enter an already uncertain market.
“In today’s climate, where economic pressures, affordability constraints, and buyer hesitation are all at play, that risk feels more pronounced than ever.
“As a result, we’re seeing a significant number of sellers prioritise certainty over maximising price, opting for routes that can guarantee a sale and remove the risk of a deal collapsing at the last minute.
“In a market where confidence remains fragile, the ability to secure a reliable outcome is becoming an increasingly important factor in how people choose to sell their home.”
