The property portal estimates that nearly £392 million in potential estate agency income and £515 million in stamp duty were lost last year from sales that fell through and did not return to the market within 12 months.
The financial impact is not confined to England. Similar failed transactions resulted in an estimated £7 million loss in Scotland and approximately £23 million in Wales.
Why Property Transactions Collapse
The figures reflect the proportion of agreed property sales that fail to complete. Rightmove’s data shows that 6 per cent of transactions fall through and do not re-enter the market within a year. A further 23 per cent initially collapse but are eventually revived and completed.
On average, it took five months for a home purchase across Britain to move from offer to completion in 2025. Extended timelines can increase the risk of buyers or sellers withdrawing, particularly if mortgage offers change, survey issues arise or property chains break down.
Rightmove based its calculations on official house sales data from HM Revenue and Customs, combined with its own average transaction price data. The estimates also accounted for transactions involving stamp duty relief for first-time buyers.
Economic Impact on Agents and Buyers
Johan Svanstrom, Chief Executive of Rightmove, said the findings highlight the economic opportunity available if fall through rates can be reduced.
He noted that more than one in five transactions are affected by fall throughs, leading to either lost or delayed fees for estate agents and forcing some buyers to incur repeat costs such as surveys and legal fees.
Industry professionals argue that the financial damage extends beyond headline figures. Craig Webster, Managing Director at Tiger Estates, said agents invest significant time and marketing resources before a sale reaches completion.
He pointed to improvements in conveyancing efficiency and better data sharing between lenders, solicitors and agents as key to reducing risk. Faster communication and early legal preparation, he said, could help prevent minor delays escalating into cancelled transactions.
Calls for Reform and Digitisation
Mary Lou Press, President of NAEA Propertymark, acknowledged that while some fall throughs are unavoidable, many could be prevented.
She emphasised the need for better upfront information, improved coordination between parties and greater digitisation of the home buying process. According to Propertymark, a more streamlined and transparent system would benefit both consumers and industry professionals.
A Structural Challenge for the UK Housing Market
With transactions taking an average of five months to complete, Britain’s property system remains vulnerable to delays and uncertainty. High fall through rates not only disrupt individual buyers and sellers but also represent a significant drag on economic activity.
Reducing collapse rates could unlock hundreds of millions of pounds in retained tax revenue and professional fees each year, while improving confidence across the housing market.
