Fall-throughs are hitting more than half of property deals (58%) after an offer is accepted, new data reveals.

Research involving 5,000 home movers also shows as many as one in six agreements collapses after four months or even later.

And the average failed transaction wastes three months, according to the Open Property Data Association (OPDA).

Outdated market

The issue is being driven by an outdated property market and a lack of upfront property information, with problems often only emerging weeks or months into the process, OPDA says.

Average fall‑through costs to buyers and sellers are an estimated £2,830 in legal fees, surveys and mortgages.

These figures lay bare a housing market that is failing consumers at every stage.”

Maria Harris, Chair at the OPDA, says: “These figures lay bare a housing market that is failing consumers at every stage. Far too many transactions collapse because crucial information only comes to light weeks or even months after an offer is made.

“Providing upfront, standardised property data through digital property packs would transform this process.

“When material information is available at the point of listing, buyers can make informed decisions, issues can be identified early, and far fewer transactions fall apart late in the process.”

Small fall

Last month, figures from TwentyEA showed property fall-through rates edged downwards in the first three months of 2026 in most regions, despite the market struggling with economic uncertainty.

The proportion of deals that collapsed was down in 10 of 13 regions, with the national trend showing a small fall from 24% to 23.7%.
