Fall-Throughs Cut to 1 in 20? What Sellers Should Believe

By Lisa Hayes · 19 September 2026

New research published on Friday 18 September suggests that fewer than one in 20 house sales would collapse after an offer is accepted, if the legal work starts the day a home is listed rather than the day a buyer turns up. That is the headline finding from LawtechUK, which studied 500 real transactions in England and Wales and recorded a fall-through rate below 5% — against a market where, on current industry figures, closer to six in ten agreed sales never make it to completion.

It is a genuinely encouraging number. It is also not a promise, it is not yet the law, and it will not be rescuing your autumn sale. Here is what the research actually says, what the Government's reforms will and won't do, and — the part that matters most — what you can copy from all of this on your own kitchen table this weekend.

What exactly happened on 18 September?

LawtechUK, an initiative backed by the Ministry of Justice, published analysis of 500 property transactions run through a "prepare first, market second" model. In plain English: instead of the seller waiting for an offer and then instructing a solicitor, the seller instructs a solicitor the moment the agent lists the property. The solicitor pulls the title, reads the lease, chases the missing window certificate and the dodgy loft conversion paperwork, and sorts out the awkward questions while the photos are still going up.

The results across those 500 transactions, according to LawtechUK:

• Fewer than 5% fell through.
• Freehold properties reached exchange in around 30 days.
• Leasehold properties, historically the slow lane, reached exchange in around 45 days.
• One deceased estate — usually a byword for delay — completed in 28 days.

The model highlighted is Conveyo, a lawtech firm whose co-founder and chief executive Konrad Rotthege said the Government's vision of getting information earlier into the process "isn't something that's years away. We've shown that it's already possible using today's technology."

Alongside it, LawtechUK published YouGov consumer research that is worth sitting with for a moment. More than a quarter of homebuyers — 27% — said conveyancing caused them prolonged stress and uncertainty. Nearly one in ten, 9%, considered abandoning their purchase entirely because of that stress. And 25% reported at least one collapsed sale that cost them money.

A quarter of buyers have been burned. That is not a niche complaint. That is the system.

Why "one in 20" is such a startling number

To understand why the industry sat up on Friday morning, you need the baseline. Figures released in May by the Open Property Data Association found fall-throughs were hitting 58% of property deals after an offer had been accepted. Read that again. On those numbers, more agreed sales in Britain fail than succeed.

Meanwhile the clock has been getting slower, not faster. Time from listing to completion has stretched to around 211 days — seven months from the day the board goes up to the day the keys change hands. Part of that is structural: more than 2,000 conveyancing solicitors have left the sector since 2022, and the ones who remain are carrying files that would have been split between two desks four years ago.

• Under 5%fall-through rate across 500 prepared transactions
• 58%of agreed sales collapse under the current system
• 30 dayslisting to exchange on freeholds in the study
• 211 dayscurrent average from listing to completion

So the gap the research points at is enormous. Roughly six in ten deals failing versus fewer than one in 20. Seven months versus one. If even half of that improvement showed up across the whole market, it would be the biggest change to the experience of selling a home in most of our lifetimes.

The bit the headline leaves out

Now for my reservations, because I'd rather you heard them from me than found out the hard way.

Those 500 transactions are not a random sample of the British housing market. They belong to sellers who chose a system that asks them to instruct a solicitor before they have a buyer, pay for legal work up front, and hand over their paperwork early. That self-selection matters enormously. A seller willing to do all that before an offer lands is, almost by definition, organised, committed and actually moving — not testing the water to see what the house might fetch.

A meaningful chunk of the market's 58% failure rate isn't caused by slow conveyancing at all. It's caused by people changing their minds, chains breaking three links away, buyers being gazumped, surveys turning up damp, mortgage offers expiring, and sellers deciding in February that actually they'll stay put. Upfront legal information fixes some of that. It does nothing whatsoever about a buyer whose own sale in Solihull just collapsed.

There's a second thing worth naming plainly. Conveyo is a commercial business, and the research showcases its own model. That doesn't make the numbers wrong — LawtechUK is Ministry of Justice-backed, and Chris Grant, the LawtechUK panel member and MD of Client Value at solicitors Goodwin who presented the findings, framed it as evidence to be examined rather than a problem solved. His actual words were that there is "an opportunity to look at evidence from successful British lawtech companies and understand what works, where the risks are and what needs to change if successful approaches are to operate at greater scale." That is a long way from "fall-throughs are fixed."

So treat under 5% as a demonstration of the ceiling, not a prediction of the average. The honest summary: front-loading legal work removes a large, specific category of delay. It cannot remove human beings from the chain.

What the Government is actually changing

The research lands against the backdrop of the Home Buying and Selling Reform Roadmap, which the Ministry of Housing, Communities and Local Government published on 19 June 2026 and called the biggest shake-up of the homebuying process in a generation. The Government's own estimate is that the package cuts about four weeks off the average transaction and saves first-time buyers an average of £650.

Three changes do the heavy lifting.

Reform	What it means in practice	Why it should reduce fall-throughs
Sales packs at listing	You would provide a standardised pack when the property goes on the market — condition, leasehold costs, chain status, title.	Buyers see the problems before they offer, so fewer discover them at week 12 and walk away.
Earlier binding contracts	The deal becomes legally binding much closer to offer acceptance, with a financial penalty for anyone who pulls out without a valid reason.	Removes gazumping and gazundering, and puts a price on casual withdrawal.
Digital identity checks	One verified digital ID, reused across agent, solicitor and lender, instead of proving who you are four separate times.	Strips out repeat admin that adds days to the start of every transaction.

Layered on top is a Code of Practice, improved listing guidance, standards governing the use of AI in conveyancing, and a consultation on estate agent qualifications. The direction of travel is unmistakable: the burden of disclosure moves onto the seller, earlier.

If you're selling, that's the sentence to underline. More of the work moves to your side of the table, sooner. The payoff is a much better chance of the sale completing — but the effort arrives first and the reward arrives later.

Are binding contracts actually good news for sellers?

Mostly yes, with one caveat nobody in the industry likes saying out loud.

The obvious win is gazundering. Right now a buyer can drop their offer by £15,000 the week before exchange, knowing you have already paid for surveys, booked removals and committed to a purchase of your own. Under earlier binding contracts that stops being a free move. If they walk without a valid reason, it costs them. That alone rebalances a negotiation that has favoured buyers for decades.

The caveat is that the penalty cuts both ways. Sellers pull out too, and often for perfectly human reasons — a job offer falls through, a relative gets ill, the onward purchase they were relying on collapses and suddenly they have nowhere to go. In a binding-contract world, "I've changed my mind" acquires a price tag for you as well. The detail of what counts as a "valid reason" is where this reform will be won or lost, and we have not seen that detail yet.

My read: if you are a committed seller with a clear reason for moving, binding contracts are straightforwardly in your favour. If you are half-testing the market to see what turns up, they are a reason to think harder before you accept an offer. Which is, I suspect, exactly the behaviour the policy is designed to produce.

When does any of this reach your sale?

Not this year. Probably not next year either, in full.

The sequencing the Government set out runs roughly like this. The Code of Practice and improved listing guidance land later in 2026. Consultation on agent qualifications and expanded digital tools follows from 2027. The full legislation covering sales packs, binding contracts and digital systems arrives by the end of this Parliament. That last phrase is doing an enormous amount of work. "By the end of this Parliament" is political language for "we intend to, at some point, if the timetable holds."

So if you are putting your house on the market this October, none of it applies to you. You are selling under the old rules, in a market where 58% of agreed deals fail and the average sale takes 211 days. The reforms are a reason for optimism about 2028. They are not a plan for your autumn.

What this means if you're selling right now

Context matters here, and the autumn context is not generous.

The Bank of England held Bank Rate at 3.75% on 17 September, but the vote was 6–3, with three members pushing for a rise to 4% — the most hawkish split of this cycle. CPI inflation climbed to 3.1% in August. Swap rates have pushed above 4.70%, and lenders including NatWest, Santander, HSBC, Lloyds and TSB have repriced fixed deals upwards, several of them more than once this month. Nobody sensible is forecasting cheaper mortgages before Christmas.

On the price side, Zoopla's latest index put UK house price growth at 0.9% in the year to July, down from 1.3% in June, with the average home at £272,800. Zoopla also calculates that higher mortgage rates have cut buyers' purchasing power by around 9% since January — a buyer who could borrow £200,000 in the new year can borrow roughly £182,000 today for the same monthly payment. And there are about 5% more homes on the market than a year ago.

Put those together and you get the market as it actually is: more competition, weaker buyers, and a transaction process that fails more often than it succeeds. You can follow the detail in our rolling coverage of UK house prices and our daily property news.

Six things you can do now, without waiting for the law

This is the part I actually care about. Everything in the LawtechUK study that produced a sub-5% fall-through rate is available to you as an individual seller, right now, for the cost of instructing a solicitor a few weeks earlier than you otherwise would.

1. Instruct your conveyancer the week you list, not the week you get an offer. This is the single highest-value change, and it is the whole basis of the research. Most sellers wait. Waiting is what turns a two-week problem into a twelve-week problem, because the title issue that surfaces in December could have surfaced in September when nobody was under pressure.

2. Order your title and read it. Restrictive covenants, missing rights of way, a shared driveway nobody has documented, a boundary that doesn't match the fence. These are the classic killers. Finding one in week two costs you a phone call. Finding one in week sixteen costs you the buyer.

3. Gather the certificates before anyone asks. Building regulations sign-off for the extension, FENSA or CERTASS for the windows, gas and electrical certificates, the boiler paperwork, the guarantee for the damp-proofing. If something is missing, you have time to arrange indemnity insurance quietly rather than at gunpoint during a renegotiation.

4. If you're leasehold, start now — genuinely now. The management pack is the number one cause of delay in leasehold sales, and freeholders and managing agents work to their own timetable, which is to say no timetable at all. The study's leasehold transactions still took 15 days longer than freehold with everything front-loaded. Without it, you are looking at months.

5. Be honest in your disclosure. The Japanese knotweed, the flood in 2022, the running argument with next door about the hedge. Hidden problems don't disappear; they detonate at survey stage, when your buyer has spent money and feels deceived. Disclosed problems get priced in at the offer, which is a conversation rather than a collapse. If any of the terminology is unfamiliar, our property jargon explained guide covers the vocabulary.

6. Price it where a 9%-poorer buyer can actually reach. No amount of legal preparation saves a sale agreed at a price the buyer's lender won't value at. A down-valuation is a fall-through with extra steps. Start with a realistic figure — our guide to how much your house is worth walks through the method, and it is worth getting more than one opinion.

Do those six things and you are running, unilaterally, the model that produced a sub-5% fall-through rate. You don't need the Government's permission.

What if you genuinely can't wait 211 days?

Sometimes the timetable isn't a preference. Probate with an empty property and a council tax bill running. A job that starts in Aberdeen in six weeks. A divorce settlement with a date on it. A chain that has already broken once and won't survive a second attempt.

In those situations the arithmetic changes, because the cost of a failed or drawn-out sale stops being abstract. Seven months of mortgage payments, insurance, council tax and standing charges on a house you have already moved out of is real money. So is the offer you lose when your buyer's patience runs out.

That is the honest case for the quick-sale route. Genuine cash house buyers aren't in a chain, aren't waiting on a mortgage offer, and don't fall through for the reasons that sink one in every two open-market sales. What you trade is price — a cash buyer will pay below market value, and anyone telling you otherwise is selling you something. For context, recent industry data showed cash-buying landlords negotiating purchases at around 88.7% of asking price, and dedicated quick-sale firms typically sit below that.

Whether that trade is worth it depends entirely on your circumstances, and I would never tell you it is the right answer by default. What I will tell you is that the number varies a lot between companies, and the only way to know what you are actually being offered is to compare more than one. Our guide to selling your house fast sets out how the process works and what to watch for.

What I'll be watching between now and the Budget

Three things, in order of how much they will affect you.

The 5 November Bank Rate decision. Three MPC members already voted for 4% in September. If inflation keeps climbing, that minority becomes a majority, and fixed rates that are already being repriced upwards go up again. For sellers, a rate rise doesn't just cool demand — it shrinks the mortgage your buyer can get between offer and completion, which is its own quiet source of fall-throughs.

The Autumn Budget. Property tax speculation has been suppressing activity since the summer, and until buyers and sellers know what is actually happening to stamp duty and any mansion-tax proposal, a chunk of the market will keep sitting on its hands. Uncertainty is its own tax.

The Code of Practice. Due later this year, and the first piece of the homebuying reforms that will touch real transactions. Watch what it says about what agents must publish at the point of listing. That is the thin end of the sales-pack wedge, and it will tell us whether the 2028 version has teeth.

The bottom line

Friday's research is real evidence that the homebuying system can work far better than it does. Under 5% instead of 58%, 30 days instead of 211 — those numbers came from actual transactions, not a model in a spreadsheet, and they deserve to be taken seriously.

But they came from sellers who did something most sellers don't: they got the house legally ready before they went looking for a buyer. The Government will eventually make that compulsory. Until then it is optional, which means it is an advantage — and advantages in a slow market with fussy buyers are not to be sniffed at.

If you're selling this autumn you'll be doing it under the old rules, in a market where mortgage rates are drifting up and buyers have roughly 9% less to spend than they did in January. Get your paperwork in order, price it where a real buyer can reach, and give yourself the best possible odds of being in the 42% that completes.

And if your timetable doesn't allow for seven months of hoping, it costs nothing to find out what a quick sale would actually put in your pocket before you decide. Compare offers from vetted buyers and see the numbers side by side — then make the call with the figures in front of you rather than the fear.
