What Percentage of House Sales Fall Through?

You’ve accepted an offer on your home. Everything seems to be moving in the right direction. Then the phone rings, and it’s bad news.

Your buyer has pulled out.

It happens far more often than most people think. Nearly one in three sales collapse before completion.

How Many House Sales Actually Fall Through?

Property Rescue’s internal data, drawn from thousands of open-market residential sales tracked between 2020 and 2026, shows that 34.6% of sales fell through before completion, more than one in three transactions.

This is consistent with broader industry estimates that roughly one in three property sales in England and Wales collapses before exchange of contracts.

It’s still a significant problem, and it means delays, wasted costs, and stress for hundreds of thousands of sellers every year.

This isn’t a one-off blip.

The UK consistently has one of the highest fall-through rates in the developed world, far higher than countries like Australia, North America, or Sweden, where transactions typically complete in under 45 days.

At What Point Do Most House Sales Fall Through?

Most fall-throughs happen between offer acceptance and exchange of contracts, typically around 8 to 12 weeks into the process.

Here’s the thing: in England and Wales, nothing is legally binding until contracts are exchanged.

Either party can walk away at any point before that, with no legal consequences.

Once contracts are exchanged, the buyer puts down a deposit (usually 10% of the purchase price). Walk away after that, and you lose it.

That’s why the vast majority of collapses happen before exchange.

Why Do House Sales Fall Through?

The reasons haven’t changed much over the years, but the proportions shift depending on the market. From what we see, the most common causes are:

• Survey issues or down-valuations
• Buyer changing their mind
• Mortgage difficulties
• Seller accepting a higher offer (gazumping)
• Chain breaks

Survey Down-Valuations

This is the single biggest sale-killer. The buyer’s mortgage lender sends out a surveyor, and the valuation comes back lower than the agreed price.

When that happens, the buyer either needs to find extra cash to bridge the gap, or the price has to be renegotiated. If neither side budges, the deal collapses.

Surveys can also flag issues the buyer wasn’t expecting, and that can lead to renegotiation or withdrawal, even on a property the seller believed was in good condition.

Mortgage Problems

Mortgage difficulties are growing fast as a reason for fall-throughs.

We’re seeing it more and more: a buyer has a mortgage agreement in principle, but when it comes to the formal application, the lender’s valuation comes in low, or the affordability checks don’t stack up.

Rate changes, stricter affordability checks, and last-minute lender decisions can all pull the rug out from under a buyer who thought they were good to go.

Chain Breaks

If your buyer is also selling, and their buyer pulls out, the whole chain can collapse.

The longer the chain, the higher the risk. One failed link is all it takes to bring the whole thing down.

Buyer Cold Feet and Gazumping

Some buyers simply change their mind. Maybe they found somewhere else. Maybe they got cold feet.

In England and Wales, there’s nothing stopping them before exchange.

Gazumping (where the seller accepts a higher offer from another buyer after already accepting yours) is a persistent cause of failed sales in England and Wales.

It’s legal, but it’s frustrating and costly if you’re the one left out in the cold.

Slow Conveyancing

Solicitor delays kill more deals than most people realise.

We’ve seen some extreme cases. One seller’s solicitor took 10 months to progress the sale, and the buyer understandably walked away.

That’s not typical, but it shows what can happen if the conveyancing isn’t managed properly.

A 2025 report identified four structural causes behind the conveyancing bottleneck: no upfront funding commitment, no upfront property information, no early contractual commitment, and an under-resourced conveyancing sector.

What Does a Failed House Sale Cost You?

A failed sale doesn’t just cost you time. It costs real money.

A 2025 report estimated that property transaction failures in England and Wales may have implied up to £8.6 billion in lost home-mover spending in 2024, including wasted professional fees, surveys, searches, and abortive agent time.

That’s the national picture. But what about you personally?

Solicitor Fees and Searches

Most solicitors still charge for work done, even if the sale falls through.

Our research into solicitor fees found the median cost to sell a freehold property is £1,155 including VAT. If the sale collapses, you’ll still owe a significant chunk of that for the work already done.

On top of that, you’ll have paid for disbursements: local authority searches, environmental searches, ID checks.

Those are non-refundable.

If you had an onward purchase lined up, you’ve also paid for searches and a survey on a property you’re no longer buying.

For a full breakdown of what solicitors charge, have a look at our guide to solicitor fees when selling a house.

The Hidden Cost: Wasted Time

But here’s what most people miss: it’s the time that really hurts.

From our experience, when a sale falls through, sellers typically face 12 to 16 weeks of wasted time.

That’s three to four months where you thought you were moving forward, and now you’re back to square one.

If you had an onward purchase lined up, that’s gone too.

You’ve lost the momentum, and you might lose the property you were buying.

How to Reduce the Risk of Your Sale Falling Through

You can’t eliminate the risk entirely.

But you can make it much less likely.

Get Your Property Information Ready Upfront

This is the single most impactful thing you can do.

The government thinks so too. MHCLG’s October 2025 consultation on home buying and selling reform estimates that requiring comprehensive upfront property information could reduce fall-through rates from approximately one in three transactions to one in seven and save consumers approximately £255 million per year in wasted costs.

You don’t have to wait for legislation. Get your title documents, EPC, lease details (if leasehold), and any planning or building control certificates ready before you list.

The fewer surprises down the line, the less likely your sale is to collapse.

A 2024 survey of 500 estate agents found that 83% believed providing upfront information would reduce fall-throughs, yet only 30% had made operational changes to do it.

Don’t wait for your agent. Do it yourself.

Verify Your Buyer’s Position

Before you invest weeks of time and money, make sure your buyer is real.

Ask for proof of funds or a mortgage agreement in principle. If they say they’re a cash buyer, ask to see a bank statement or solicitor’s confirmation.

We had a seller in Manchester who’d been waiting 12 weeks for what they thought was a cash buyer. Turned out the money was tied up in an inheritance that hadn’t come through.

We stepped in and completed in 28 days.

But those 12 weeks were completely wasted and entirely avoidable if the buyer’s funds had been verified upfront.

Choose the Right Solicitor

A slow or unresponsive solicitor can drag your sale out for months, and the longer it takes, the more likely it is to fall through.

Choose a solicitor with a track record of completing on time. Ask how many transactions they’re handling. Ask how they manage sales progression.

If they can’t give you a clear answer, find someone who can.

For context: on the property buying side of our business, we work with a panel of experienced conveyancing solicitors. While sellers must have their own independent legal representation (as required by SRA regulations), we can often recommend efficient solicitors who complete transactions quickly.

That keeps communication flowing, reduces delays, and means completions happen in weeks rather than months. Combined with the fact that we’re a cash buyer with no chain, our fall-through rate on direct purchases is only around 10%, compared to the nearly 29% industry average on the open market.

Consider a Lock-Out Agreement

A lock-out agreement gives your buyer an exclusive period (typically 2 to 4 weeks) during which you won’t accept other offers.

It doesn’t prevent them from pulling out.

But it shows commitment on both sides and gives the transaction a better chance of reaching exchange.

What To Do If Your Sale Falls Through

First: don’t panic.

Remember, in our dataset, every property that fell through eventually sold.

The question is how long you’re willing to wait, and how much uncertainty you can handle.

Relist With Your Agent

If you’ve got time, go back to market.

Your agent should be able to re-market the property quickly, and you may already have other interested parties from the original listing.

Think about what went wrong. If the buyer’s mortgage fell through, you might want to prioritise cash buyers or those with a stronger lending position next time.

Sell to a Cash House Buyer

If speed and certainty matter more than getting the absolute top price, a cash buyer removes most of the reasons sales fall through: no mortgage to arrange, no chain, no protracted conveyancing.

We receive around 100 enquiries every month from sellers whose buyer has pulled out. It’s one of the most common reasons people come to us.

We buy over 500 properties a year, and our average completion time is 28 days from the day we agree a price.

You’ll get a cash offer within 24 hours, exchange can happen in as little as 48 hours, and there are no estate agent fees.

The trade-off is price. A cash sale will be below open-market value; that’s the cost of speed and certainty.

But for sellers who’ve already been through the stress of a collapsed sale, knowing the deal will actually complete is often worth more than the difference in price.

Could Reform Fix the Problem?

In Scotland, the fall-through rate after offer is estimated at around 8-9%, compared to roughly 30% in England and Wales.

The difference? Scotland’s legal framework requires solicitors to conclude binding “missives” (formal offer and acceptance letters) much earlier in the process.

Once missives are concluded, walking away has real financial consequences.

In England and Wales, you can shake hands, instruct solicitors, pay for searches and surveys, and the buyer can still walk away with no penalty right up until exchange.

The government ran two consultations on home buying and selling reform in late 2025, which closed in December. The proposals include mandatory upfront property information, earlier binding agreements, and professionalising property agents.

A roadmap is expected in the first half of 2026, but the Law Society has noted the proposals still lack sufficient detail, and any changes are likely years away from implementation.

But until the law changes, the risk remains.

And the best thing you can do is take steps to protect yourself.
