How Long Should You Give Your Buyer to Exchange?

One of the most frustrating parts of selling a property in England and Wales is the gap between accepting an offer and exchanging contracts. During this period, neither party is legally committed. The buyer can pull out at any time, and so can you. According to the HomeOwners Alliance, around one in three agreed sales falls through before exchange, and many of these collapses happen because the process simply dragged on too long.

As a seller, you need to balance patience with pragmatism. Give your buyer too little time and you risk losing a genuine purchaser who is working through a legitimate process. Give them too much time and you may waste months on a buyer who was never going to complete, missing other opportunities in the meantime. This guide helps you find the right balance.

What is a normal timeline from offer to exchange?

According to HM Land Registry data and the Law Society'sConveyancing Protocol guidance, the typical timeline from accepted offer to exchange of contracts in England and Wales breaks down as follows:

The five milestones you should be tracking

Rather than simply counting weeks, track the specific milestones that indicate whether your sale is genuinely progressing. These are the five that matter most:

1. Buyer's solicitor instructed and memorandum of sale received. This should happen within the first week. If the buyer has not instructed a solicitor within two weeks of your accepting the offer, treat it as a serious red flag. A buyer who delays instructing a solicitor is often not committed to the purchase.
2. Searches ordered. The buyer's solicitor should order searches within the first two weeks. Your estate agent can ask the buyer's solicitor to confirm that searches have been ordered. If they have not been ordered after three weeks, ask why. For more on what searches involve and how long they take, see our guide on how long after searches to exchange.
3. Enquiries raised and responses sent. Once the buyer's solicitor has the contract pack and search results, they will raise enquiries. This is normal and necessary, but the process should not drag on indefinitely. If enquiries have not been raised within three weeks of the contract pack being sent, or if your solicitor's responses are sitting unanswered for more than two weeks, something is wrong.
4. Mortgage offer issued. For a buyer who needs a mortgage, the formal mortgage offer is one of the final pieces of the puzzle. Most mortgage offers take three to six weeks from application. If the buyer has not received a mortgage offer by week eight, you should be asking whether the application has been submitted, whether the valuation has taken place, and whether the lender has raised any issues.
5. Solicitors confirm readiness to exchange. Once searches are back, enquiries are resolved, and the mortgage offer is in place, both solicitors should confirm they are ready to exchange. This final step should take no more than one to two weeks. Any delay at this stage usually means something has come up — ask your solicitor what it is.

When to start putting pressure on

There is no single moment when you should flip a switch from patient to impatient. Instead, use the milestones above to calibrate your response:

Weeks 1 to 4: monitor and support

During the first month, the conveyancing process is getting started. Your solicitor is preparing and sending the contract pack, the buyer's solicitor is ordering searches, and the mortgage application is being processed. This is not the time to apply pressure, but it is the time to make sure everything has been set in motion. Ask your estate agent to confirm that the buyer has instructed a solicitor, that searches have been ordered, and that the mortgage application has been submitted.

Weeks 4 to 8: chase actively

By week four, searches should be back or close to completion, the first round of enquiries should have been raised, and the mortgage valuation should have taken place. If any of these have not happened, ask your estate agent to find out why. This is where a proactive approach — from you, your solicitor, and your agent — makes the difference between a sale that completes on time and one that drifts. For specific tactics, see our guide on how to speed up conveyancing as a seller.

Weeks 8 to 12: set a deadline

If you are approaching 12 weeks without exchange and there is no clear remaining obstacle (such as a known slow local authority search), it is time to set a formal deadline. We will cover how to do this in the next section.

Beyond 12 weeks: escalate

At this point, you should be having a direct conversation with your estate agent about whether the buyer is going to exchange. If the buyer cannot explain the delay or give a credible date for exchange, you should seriously consider your options — including remarketing.

How to set a deadline for exchange

Setting a deadline is a commercial negotiation, not a legal one. There is no mechanism in English property law to compel a buyer to exchange by a specific date — until contracts are exchanged, either party can walk away. But a clearly communicated deadline serves two important purposes: it concentrates minds, and it gives you a defensible basis for remarketing if the buyer fails to deliver.

Here is how to do it effectively:

1. Ask your solicitor what is actually outstanding. Before setting a deadline, understand exactly where things stand. Get a specific list of what needs to happen before exchange can take place — outstanding enquiries, missing documents, mortgage offer status, search results still awaited. Your deadline needs to be realistic given what remains.
2. Communicate through your estate agent. The deadline should be communicated by your estate agent to the buyer and the buyer's estate agent (if they have one). Keep the tone firm but professional. The message should be clear: you need exchange by a specific date, and if it does not happen, you will begin considering other options.
3. Put it in writing. Ask your estate agent to confirm the deadline in an email to the buyer and the buyer's solicitor. A verbal conversation is easily forgotten or misremembered. Written communication creates a record and is taken more seriously.
4. Give a specific date, not a vague timeframe. “We need to exchange by Friday 20 March” is far more effective than “we need to exchange within the next few weeks.” A specific date creates urgency and accountability.
5. Make the deadline reasonable. The Law Society's guidance and general conveyancing practice suggest that two to three weeks is a reasonable period to give for a deadline, assuming the main substantive work is complete. If there are genuine outstanding issues (such as search results still being awaited from the council), your deadline should account for those.
6. State the consequence clearly. The deadline only works if the buyer believes you will act on it. Say explicitly that if exchange does not happen by the date, you will begin remarketing the property. And mean it.

Genuine delays versus warning signs

Not all delays are the buyer's fault, and not all delays are a sign that the sale is in trouble. The key is to distinguish between delays that have a clear cause and a foreseeable resolution, and delays that suggest the buyer is not going to complete. Here is how to tell the difference:

Delays that are usually genuine

• Slow local authority searches. Some councils in England take six to eight weeks to return local authority search results. This is outside the buyer's control. You can check your council's current turnaround time and factor it into your expectations.
• Mortgage lender delays. Lenders occasionally take longer than expected to process applications, particularly if they request additional documentation or if the valuation flags issues. If the buyer can show that the application is in progress and the lender has not declined it, this is usually a genuine delay.
• Chain dependencies. If your buyer is also selling a property, their ability to exchange depends on their own buyer being ready. Chain delays are frustrating but common, and the solution is often patience combined with regular updates on the status of the entire chain.
• Complex enquiries. Some properties generate legitimate additional enquiries — for example, properties with boundary disputes, planning issues, or restrictive covenants. These take time to resolve properly.

Warning signs that the buyer may not exchange

• The buyer has not instructed a solicitor within two weeks. A buyer who is serious about purchasing will already have a solicitor in mind or will instruct one within days of having an offer accepted.
• The buyer's solicitor is not responding to correspondence. If your solicitor or estate agent cannot get a response from the buyer's solicitor, the transaction is effectively stalled. This could mean the buyer has not paid their solicitor, has changed their mind, or has instructed a firm that is overwhelmed.
• The mortgage application has not been submitted after four weeks. A buyer who has not applied for their mortgage within a month of having an offer accepted is either not financially ready or not committed.
• Repeated requests for more time with no specifics. “We just need a bit more time” without any explanation of what is being waited on is a classic stalling tactic.
• The buyer is renegotiating the price. If the buyer raises price reduction demands late in the process — particularly after the survey — they may be looking for an excuse to pull out or trying to pressure you into a lower price while you feel committed to the sale.
• Your estate agent has concerns. Estate agents see many transactions and can often sense when a buyer is not going to proceed. If your agent tells you they have doubts, take that seriously.

Ultimatum strategies that work

If you have set a deadline and it has passed, or if you are dealing with a buyer who is clearly not progressing, you have several options. The right strategy depends on your circumstances, including how urgently you need to sell, how strong the market is, and whether you have other interested parties.

Option 1: Final deadline with a specific exchange date

This is the most common approach. Through your estate agent, tell the buyer that you need contracts exchanged by a specific date (typically two to three weeks away) and that if exchange does not happen, you will put the property back on the market. Be prepared to follow through.

Option 2: Remarket while keeping the current buyer

You are not obliged to take your property off the market while a sale is progressing. If your buyer is dragging their feet, you can instruct your estate agent to begin remarketing — either quietly (continuing to show the property to new enquiries) or openly (relisting on the portals). This sends a clear signal to the current buyer that their position is not secure, and it gives you a fallback if they pull out.

Option 3: Set a “best and final” date for exchange

If you have received interest from other buyers, you can tell all interested parties — including your current buyer — that you will proceed with whichever buyer can exchange first. This creates competitive pressure and can unlock a stalled transaction.

Option 4: Withdraw and remarket

If you have genuinely lost confidence that the buyer will exchange, the cleanest option is to withdraw, remarket the property, and start fresh. This feels drastic, but the alternative — continuing to wait for a buyer who may never exchange — can cost you months. Many sales that drag beyond 16 weeks without exchange eventually fall through anyway.

Keeping backup buyers interested

One of the strongest positions you can be in as a seller is having more than one interested buyer. This gives you leverage when setting deadlines and provides a safety net if the primary sale falls through. Here is how to manage it:

• Ask your estate agent about ongoing interest. A good agent will continue to field enquiries and keep a record of interested parties even after an offer has been accepted. Ask them regularly whether anyone else has expressed interest.
• Do not refuse all viewings. While it is standard practice to take a property off the portals once an offer is accepted, you are not legally required to do so. If your current buyer is slow to progress, consider keeping the listing active or at least accepting viewings from seriously interested parties.
• Be transparent with the backup buyer. If you have a second interested party, be honest with them about the situation. Tell them you have an accepted offer that is progressing slowly, and ask whether they would be interested in proceeding if the current sale falls through. Most serious buyers will appreciate the honesty.
• Move quickly if you switch buyers. If your primary sale does fall through and you have a backup buyer ready, the advantage of having prepared your legal documents upfront is significant. Your solicitor already has the contract pack ready and can send it to the new buyer's solicitor immediately, saving weeks. This is one of the core benefits of using Pine to prepare your sale documents before marketing.

Remarketing: what to consider before pulling the trigger

Before you decide to pull out and find a new buyer, consider the following factors:

• How strong is the market? In a buoyant market, finding a new buyer quickly is realistic. In a slow market, it could take weeks or months, and you may not achieve the same price. Check recent comparable sales in your area and ask your estate agent for an honest assessment.
• How far along is the conveyancing? If the buyer has completed searches, resolved most enquiries, and has a mortgage offer in place, you are close to exchange. Walking away at this point means a new buyer will need to go through the entire process from scratch. However, if the buyer has barely started, you have less to lose.
• What costs have you incurred? If the sale falls through, you will not recover conveyancing costs already spent (unless your solicitor offers a no-sale-no-fee arrangement). Factor this into your decision.
• Is your own onward purchase at risk? If you are buying another property and your seller is putting pressure on you, a delay in your sale can have cascading consequences. In this situation, you may need to act more quickly.
• Do you have an alternative buyer? If you have a backup buyer who is mortgage-approved and ready to proceed, switching may be straightforward. If you have nobody else interested, you are starting from zero.

What happens once contracts are finally exchanged?

Once your buyer exchanges contracts, they are legally committed to the purchase. They will have paid a deposit (typically 10 percent of the purchase price), and if they pull out after this point, you are entitled to keep the deposit and may be able to claim additional damages. The completion date is fixed at exchange — usually one to four weeks later, though two weeks is the most common gap.

A practical timeline for managing your buyer

Here is a week-by-week summary of what you should expect and when to take action:

How preparing your documents upfront helps

Much of the frustration around exchange timelines comes from preventable delays on the seller's side. If your solicitor takes two or three weeks to send the contract pack after the offer is accepted, you have already lost time before the buyer's side has even started their work.

This is where upfront preparation makes a measurable difference. By completing your TA6, TA10, and other seller forms before you accept an offer — and having your solicitor prepare the draft contract pack in advance — you can get the contract pack to the buyer's solicitor within days of the offer rather than weeks. That means searches, enquiries, and the mortgage process all start sooner, and the entire timeline compresses.

Pine is designed to support exactly this approach. By helping you get your legal paperwork ready before you go to market, you are in the strongest possible position when you accept an offer — and you have the best chance of reaching exchange within a reasonable timeframe.
