Sold Subject to Contract (SSTC): What It Really Means (2026)

By Lisa Hayes · 1 August 2026

"Sold subject to contract" (SSTC, or Sold STC) means a seller has accepted a buyer's offer, but nobody is legally tied to anything yet. In England and Wales the sale only becomes binding at exchange of contracts, which happens weeks later. Until then, either side can walk away, renegotiate, or accept a better offer, and no law stops them.

So when your agent rings to say your house is now SSTC, enjoy the moment. Then take a breath. You've cleared a real hurdle, but you're closer to the start of the legal process than the end of it. This guide walks through exactly what the label means, what happens next, how long it takes, why roughly a quarter of agreed sales still fall apart, and the practical things you can do to make sure yours isn't one of them.

What does "sold subject to contract" actually mean?

It's an estate agent's status, not a legal one. The agent marks a property SSTC once the seller accepts an offer, to signal to other buyers that a deal has been struck and to more or less take the house off the active market. The phrase is doing a lot of quiet work in those four words: the sale is agreed subject to a contract that hasn't been drafted, checked, or signed yet.

You'll see it written a few ways. "SSTC", "Sold STC", and "Sold subject to contract" all mean the same thing. On Rightmove and Zoopla the listing usually gets a "Sold STC" flag rather than disappearing. That visibility matters, and we'll come back to it.

The government's own guidance on how to sell a home is blunt about the sequence: an accepted offer is not legally binding, and in England and Wales the point of no return is exchange of contracts. Everything between offer and exchange is negotiable, cancellable, and, frankly, a bit nerve-wracking. If you want the rest of the vocabulary decoded, our property jargon explained guide covers the terms you'll meet along the way.

Is SSTC legally binding? Can either side pull out?

No, and yes. Nobody is committed at SSTC, so either the buyer or the seller can pull out at any point before exchange, for any reason or none, without owing the other party a penny for the sale itself. That surprises people. You shook hands, the agent sent the paperwork to the solicitors, it feels done. Legally, it's a handshake and nothing more.

In practice that cuts both ways:

• A buyer can reduce their offer close to exchange. That's gazundering, and it happens most when the market softens and buyers know sellers are emotionally and financially committed to moving.
• A seller can accept a higher offer from someone else. That's gazumping, and it's perfectly legal right up until contracts exchange.
• Either side can simply change their mind. A job falls through, a survey spooks a buyer, a relationship ends. No penalty applies.

You cannot make an accepted offer binding just by wanting it to be. What you can do is push hard to reach exchange quickly, because the sooner contracts exchange, the shorter the window for anything to go wrong.

SSTC vs under offer vs sold vs exchanged: what's the difference?

These get used loosely, and the loose usage costs people money because they misjudge how safe their sale is. Here's how the stages actually line up.

The honest takeaway: "under offer" and "SSTC" sit on the same shaky ground. Only exchange makes the deal real. Anyone who tells you a sale is "as good as done" at SSTC is being optimistic, not accurate.

What happens after a property goes SSTC?

This is where the actual work starts. Once you're SSTC, a whole conveyancing process kicks off in the background, and it involves solicitors, searches, surveys, mortgage lenders and, if there's a chain, several other households doing the same dance at the same time. Roughly, it goes like this:

1. Instruct solicitors. Both sides appoint a conveyancer. If you haven't lined one up before accepting, you've already lost a week or two. Our guide on whether you need a solicitor to sell your house explains what they actually do here.
2. Draft contract and property forms. Your solicitor sends the buyer's side the draft contract plus the TA6 (property information) and TA10 (fittings and contents) forms. Fill these in honestly and fully. Vague answers create questions, and questions create delay.
3. Searches. The buyer's solicitor orders local authority, water and drainage, and environmental searches. Turnaround varies by council and is one of the most common causes of a stall.
4. Survey and mortgage valuation. The buyer's lender values the property and the buyer may commission a fuller survey. A down valuation here can blow a hole in the agreed price.
5. Enquiries. The buyer's solicitor raises questions off the back of the forms and searches. Your solicitor answers. This back-and-forth is where weeks quietly disappear.
6. Exchange of contracts. Everyone's happy, the deposit is ready, a completion date is agreed. Contracts exchange. Now it's binding.
7. Completion. Funds move, usually by CHAPS transfer, and the keys change hands. If you're wondering exactly when you get the money when you sell your house, it's on this day.

How long does SSTC to completion take in the UK?

Plan for six to twelve weeks from SSTC to completion, and be pleasantly surprised if it's quicker. A straightforward, chain-free sale with organised solicitors can close in six to eight weeks. Add a chain, a slow council, a mortgage hiccup or a probate complication and you can be looking at three to six months.

• 6–12 wkstypical SSTC to completion
• ~120 daysaverage full purchase, per GOV.UK
• 1–14 daysexchange to completion
• 6–8 wksif there's no chain

The government puts the average home purchase at around 120 days from offer to completion, which is a big part of why it's overhauling the whole system (more on that below). For a fuller breakdown of the stages and what drags them out, see how long it takes to sell a house in the UK.

Once contracts exchange, completion follows anywhere from the same day to about two weeks later, depending on what date everyone agreed. Same-day exchange and completion happens, usually in chain-free sales, but most people leave a gap to organise removals and money.

A realistic timeline helps. Say you accept an offer on the 1st of the month with solicitors already lined up. Draft contracts and forms go out in week one. Searches are ordered and take three to six weeks to come back, running alongside the buyer's mortgage valuation in weeks two and three. Enquiries bounce between the two solicitors through weeks four and five. If nothing snags, you exchange around week six to eight and complete a week or two after that. Now imagine you're the third property in a five-house chain: your slick six-week sale is hostage to whoever is slowest, and that's usually where the timeline balloons.

Should you keep your house on the market after SSTC?

Strictly, that's your call as the seller, and there's a real judgement in it. Leaving the listing active (or telling the agent to keep taking enquiries) gives you a backup if your buyer collapses, but it signals you're not fully committed and can unsettle the buyer you've got. Pulling it entirely gives your buyer confidence and reduces the temptation to gazump, but leaves you exposed if they walk.

My honest steer for most sellers: take it off the active market once you've accepted, but don't relax. Commitment tends to be reciprocated, and a buyer who feels secure is a buyer less likely to get twitchy at the first survey wrinkle. Keep a mental note of your underbidders, though. If the sale does fall over, a quick call to the second-place buyer can save you weeks of re-marketing.

Can you still view or make an offer on an SSTC property?

Yes to both, and this is the part that trips up sellers who assume SSTC means "hands off". Because the listing usually stays live online, other buyers can still see it, book viewings, and put in offers. Whether the agent passes those on depends on their instructions and the law: agents have a legal duty to forward all offers to the seller unless the seller has told them in writing to stop.

For a buyer, a Sold STC property is a long shot but not a closed door, especially if the sale is dragging. For a seller, it's a double-edged sword. A higher late offer is tempting, but accepting it means gazumping your existing buyer, torching the goodwill you'll need if your onward purchase wobbles. My view: only entertain a fresh offer at SSTC if your current buyer is genuinely stalling or messing you about. Chopping and changing for a few thousand pounds usually costs more in delay and stress than it's worth.

What does SSTC mean if you're the buyer?

Most people reading this are selling, but it's worth flipping the coin, because understanding the buyer's incentives helps you manage them. For a buyer, an accepted offer marked SSTC means the same fragile thing: no commitment until exchange. That freedom is a shield (you can pull out if a survey turns up a nasty surprise) and a temptation (you could try to gazunder near exchange). The savvy sellers I've seen keep their buyer moving with small, steady wins: prompt answers, a tidy set of documents, no nasty surprises in the searches. A buyer who feels the process is competent and honest is far less likely to get cold feet or start chipping at the price. If you're buying and selling at once, you're living both sides of this at the same time, which is exactly why chains are so brittle.

How often do SSTC sales fall through, and why?

This is the uncomfortable heart of it. A big chunk of agreed sales never make it to completion. Government figures put it at roughly one in three, and market trackers have measured the UK fall-through rate at around 23 to 24% through 2026, close to the decade average of about 24.5%. In plain terms: agree a sale today, and there's a meaningful chance it won't complete.

When sales do collapse, the reasons cluster. Recent 2026 tracking of fall-throughs found survey and valuation problems as the single biggest cause, followed closely by a buyer or seller having a change of heart, then broken chains and mortgage or affordability issues.

• Survey / valuation issues ~38%
• Buyer or seller changes their mind ~31%
• Chain collapse chain
• Mortgage / affordability funding

Two things stand out from those numbers. First, most fall-throughs aren't random bad luck; they're triggered by a specific, often predictable event like a down valuation or a link snapping in the chain. Second, the further along you are, the more painful and expensive a collapse becomes, because both sides have usually paid for searches, surveys and legal work by then. The government reckons failed transactions cost sellers around £400 million a year and the wider economy up to £1.5 billion. That's a staggering amount of money set on fire by a system that lets people commit late.

It's worth being concrete about what a collapse actually costs you. If your sale dies after searches and legal work are under way, you can be out of pocket for wasted conveyancing (often a few hundred pounds even on a no-completion-no-fee basis, because search fees and disbursements are non-refundable), any survey or valuation you'd commissioned on your onward purchase, a mortgage arrangement or broker fee you may lose, plus removal deposits. And then the real cost: weeks or months back on the market, quite possibly at a lower price if the market has moved against you. A sale that falls through at week ten hurts far more than one that never got going.

How do you stop your SSTC sale from falling through?

You can't eliminate the risk, but you can stack the odds heavily in your favour. After years of watching sales survive and sales die, the difference usually comes down to preparation and pace, not luck.

The buyer you accept matters as much as the price they offer. A chain-free, mortgage-ready buyer at slightly under asking is often safer than a top-dollar buyer stuck at the bottom of a five-link chain. If your sale sits inside a chain, read what to do when a property chain collapses before you need it, not after.

Does SSTC mean the same thing in Scotland?

No, and this catches people who move across the border. Scotland runs a different system. Offers are usually submitted by a solicitor, and once the formal letters (the "missives") are concluded, the deal becomes legally binding far earlier than an English exchange of contracts. Pulling out after concluded missives can mean paying damages. So the loose, anyone-can-walk-away nature of English SSTC simply doesn't apply north of the border in the same way. Scottish sellers get certainty sooner; English and Welsh sellers get a long, exposed gap. It's one of the sharper contrasts in UK property.

Will the 2026 homebuying reforms change what SSTC means?

Eventually, yes, and it's overdue. In June 2026 the government set out a plan to make buying and selling faster and more certain, built on three ideas: upfront information (a sales pack with searches, title and property details ready before a property even lists), digital property logbooks, and binding conditional contracts that would commit both sides much earlier, potentially soon after an offer is accepted.

If that lands as intended, the meaning of "sold subject to contract" shifts from "either of us can vanish for weeks" to "we're committed, subject to a short list of conditions". The catch is timing. Ministers have been clear that binding contracts won't be forced until the upfront sales packs are tested and embedded first, and the reforms are being phased through to 2030. So for any sale you're doing today, or next year, the old rules still apply: nothing is safe until exchange. Treat SSTC as a promising start, not a done deal.

Is there a way to skip the SSTC uncertainty altogether?

There is, and it's worth understanding even if you decide against it. The entire fragile gap between SSTC and exchange exists because open-market buyers depend on mortgages, chains, and their own change of heart. Take those out, and the risk largely goes with them.

A genuine cash buyer with funds in place doesn't need a mortgage valuation, isn't in a chain, and can move to a fixed completion in a fraction of the usual time. That's the core appeal of a cash house buyer or a regulated quick-sale company: certainty and speed, in exchange for accepting below full market value. It isn't the right route for everyone. If you have time and a strong property, the open market will usually get you more. But if a collapsed sale would be a disaster, if you're facing a deadline, a repossession, a divorce or a probate sale, the trade-off can be well worth it.

If you go that way, choose carefully. Not every "we buy any house" outfit is genuine, and lowball offers dressed up as valuations are common. Our guide to the best house buying companies explains what a legitimate buyer looks like, and how to sell your house fast covers the wider options if speed is your priority.

The bottom line on sold subject to contract

SSTC is genuinely good news. Someone wants your house and you've agreed a price. But it's a status, not a safeguard, and treating it as the finish line is exactly how people get caught out when a survey disappoints or a chain snaps. Keep the pressure on. Answer everything quickly, keep your solicitor honest, know who your buyer really is, and don't exhale until contracts exchange.

And if certainty matters more to you than squeezing out the last few thousand pounds, it's worth seeing what a chain-free offer looks like next to your open-market sale. Compare offers with a free, no-obligation valuation and decide with the numbers in front of you.
