Once your offer is accepted, the property is marked "sold subject to contract" and the legal and financial work begins: instruct a solicitor, apply for your mortgage, book a survey, and wait on searches. Nothing is binding until exchange, so the goal now is to move quickly and keep the chain calm.
Once your offer is accepted, the property is marked sold subject to contract and the real work begins. There is no celebration to mark a finished deal, because in England and Wales the deal is not yet finished or even binding. What an accepted offer does is start three things running in parallel: the legal work, your mortgage application, and the survey. Your job now is to keep all three moving and to stay calm if the chain wobbles.
The order of play is straightforward: instruct a solicitor, apply for your mortgage, book a survey, and wait on searches. Speed matters here, not because anyone is rushing you, but because the gap between acceptance and exchange is the window in which deals fall through. The faster you reach exchange, the less exposed you are.
What "sold subject to contract" actually means
Sold subject to contract, or sold STC, means the seller has agreed to sell to you in principle. The listing usually stops actively showing to new buyers, but the property is not legally off the market. The seller can still entertain other offers, and you can still withdraw. Nothing is locked in until contracts are exchanged. Treat the STC period as a race to exchange rather than a finish line you have already crossed.
It is also worth asking the agent to update the listing to sold STC promptly and, if you feel exposed, to request that the property is taken off the market while your purchase progresses. A seller cannot be forced to agree, and even if they do it is not legally binding, but a willingness to do so is a useful signal of good faith. If a seller refuses outright, that tells you something about how committed they are to your offer — information worth knowing early.
The immediate checklist
Doing all of this in the first few days, rather than letting a week or two drift, is the single biggest thing in your control. A seller watching a buyer move quickly is far less likely to be tempted by a later offer, because switching would mean starting the clock again.
Why speed is the whole game now
It is worth being clear about why everyone tells you to hurry. The period between acceptance and exchange is the only window in which the deal can fall apart for free: the seller can accept a higher offer, you can get cold feet, a survey can derail things, or a chain can collapse. Every week you shave off that window is a week of risk removed. You are not rushing the legal work — your solicitor will take the time the title needs — you are simply refusing to add avoidable delay on top of the unavoidable.
Practically, that means returning your solicitor's forms the day they arrive, getting your full mortgage application in straight away rather than a fortnight later, and booking your survey as soon as the seller's side will allow access. None of these is hard. They simply require you to treat the early, quiet weeks as active rather than as a lull.
What a survey can do for you
A survey is not just a box to tick for your lender. A good one is your strongest post-acceptance negotiation lever. If it turns up real defects — damp, roof problems, dated wiring, subsidence concerns — you have a legitimate, evidence-backed reason to ask for a price reduction or for the seller to carry out works. The key is to quote costed estimates rather than vague worries. "The survey flags the roof and a roofer has quoted around X to repair it" is a number a seller can respond to. Our guide to negotiating house price has a script for exactly this conversation.

Managing the chain
If there is a chain — buyers and sellers whose moves all depend on each other — your purchase can only go as fast as its slowest link. You cannot control the other parties, but you can keep your own end faultless: respond to your solicitor the same day, return forms promptly, and chase your broker for the mortgage offer. Ask the agent for honest updates on the chain so you know early if a link is in trouble. A calm, well-informed buyer is an asset to a chain, not a risk to it.
Gazumping, and how to reduce the risk
Gazumping is when a seller accepts a higher offer from another buyer after already accepting yours, before exchange. It is legal in England and Wales, frustrating, and entirely a product of that pre-exchange gap. You cannot prevent it outright, but you can shrink the window: move fast to exchange, stay proceedable, and keep a good relationship with the agent so you hear about any rival interest early. Some buyers ask the seller to take the property off the market once an offer is accepted, which is reasonable to request even though it is not binding.
Down-valuations: the other thing to watch
When your lender arranges its mortgage valuation, there is a chance the surveyor values the property below the price you agreed. This is a down-valuation, and it matters because the lender will only lend against its own figure. If that happens you have three options: make up the gap from savings, ask the seller to drop the price to the valuation, or renegotiate somewhere in between. A down-valuation is not a disaster — it is independent evidence that the price was high, and most sellers understand that the next buyer's lender is likely to reach the same conclusion. It is one of the strongest, least emotional levers you can have.
Exchange and completion
When searches are back, the mortgage offer is in hand, and your solicitor is satisfied with the title, you reach exchange of contracts. You pay your deposit, a completion date is agreed, and the deal becomes binding on both sides. Completion follows — often a week or two later, sometimes the same day — when the balance is paid, ownership transfers, and you collect the keys.

Before you celebrate, check the number still holds
Acceptance is a good moment to sense-check that you have agreed a fair price, not just a price the seller was happy with. Broc reads the evidence on the property — comparable sales, time on the market, and seller pressure — so you know whether your accepted offer sits at or below fair value, and where a survey finding might give you room to revisit it. And if circumstances change, you are not trapped: until exchange, you can still back out of the offer.

Frequently asked questions
Is my offer binding once accepted?
No. In England and Wales nothing binds until exchange of contracts. Until then either side can withdraw or renegotiate, which is why moving promptly towards exchange is the best protection against being gazumped.
Can I still negotiate after acceptance?
Yes. If a survey reveals defects, you can renegotiate using costed evidence — for example a builder's estimate for a roof or damp repair. A renegotiation backed by figures is far harder for a seller to dismiss than a request with no detail.
How soon should I instruct a solicitor?
Immediately. Conveyancing is usually the longest part of the timeline, so the sooner your solicitor is instructed and your searches are ordered, the sooner you reach exchange. Have one lined up before you offer if you can.
