How often do house sales fall through?
Often. Quick Move Now's analysis put the fall-through rate at nearly 24% in the first quarter of 2026. Timing matters too: 38% of fall-throughs occur within the first four weeks of a sale being agreed.
Why do house sales fall through?
Quick Move Now's research into failed sales in early 2026 found the leading causes were:
- Survey problems: Survey issues (37.5%) were the biggest single cause, with physical issues found during inspections.
- A change of heart: nearly a third of failed sales, often linked to nerves about the market.
- Chains and mortgages: chain breaks and lending problems each caused about one in eight failures.
- Legal hold-ups: slow or complicated conveyancing caused the rest.
What does a failed sale cost you?
Propelr estimates a collapsed sale typically costs the seller between 1,000 and 3,000 pounds in wasted legal and search fees. The bigger cost is time. Rightmove's July 2026 figures put the average time from listing to completion at 216 days, so starting again can add months of mortgage payments, council tax and bills on a home you'd planned to leave.
What should you do in the first week?
- Ask exactly why the sale failed. If it was the survey, get the report details. If it was the chain, find out whether it could be rescued.
- Talk to your agent about relaunching. Other buyers who viewed may still be interested.
- Ask your solicitor what work can be reused, such as searches and forms, for the next buyer.
- Check your price against what has actually sold nearby since you listed.
- Fix any survey problems you can, or get quotes, so the next buyer isn't scared off by the same issue.
How can you stop the next sale falling through?
- Deal with known problems before relisting, as survey issues are the most common cause.
- Check the buyer's position: mortgage in principle, deposit, and whether they have a home to sell.
- Get your paperwork ready early, so conveyancing doesn't drag.
- Keep in touch with the buyer, especially in the first four weeks, when most sales collapse.
What if you've already moved out?
If the house is empty, every extra month costs money. Check your insurance, because standard cover often restricts once a home has been empty for 30 days, and check your council tax. While you find a new buyer, short stays can cover the bills, with viewings always put first.
A warning if the house was let: if you ended a tenancy using the selling ground, the letting ban means you can't let the home again, including as a short let, for 12 months. Read the letting ban explained.

Nearly 24% in the first quarter of 2026, according to Quick Move Now's analysis.
When do most sales fall through?
38% of fall-throughs happen in the first four weeks after a sale is agreed.
Can I get my legal fees back if my sale falls through?
Usually not, unless your solicitor offered a no-sale, no-fee deal. Ask what work can be reused.
