The short answer
Typically £700 to £2,000 in England and Wales, and none of it is recoverable: conveyancing searches at £250 to £450, a survey at £400 to £1,500, and an abortive legal fee of £100 to £300. Lender arrangement fees can add more.
The figure depends entirely on how far you got. Nothing is committed at the offer. Searches are paid on order and never refunded. The survey is paid whatever it finds. Around one in four agreed sales collapsed in the first quarter of 2026, and the government puts the national cost of fall-throughs at roughly £400 million a year.
Why this matters for your purchase
This is the kind of thing a PropM8 Property Intelligence Report is built to surface early, before solicitors, surveyors or lenders are involved, while it still costs nothing to walk away.
