When Do Sellers Exchange Contracts in England?

A buyer may have made their offer, the survey may be finished and removal quotes might already be sitting in your inbox.

But the property is not legally sold until contracts are exchanged.

So, when do sellers exchange contracts in England?

Exchange normally takes place once the legal work is complete, the buyer’s finances are ready, any outstanding enquiries have been resolved and everyone in the property chain has agreed a completion date.

There is no fixed number of weeks after accepting an offer when exchange must happen. A straightforward chain-free transaction can move relatively quickly, while leasehold paperwork, mortgage delays, survey issues or a longer property chain can add considerably more time.

The important milestone is not how many weeks have passed. It is whether every part of the transaction is genuinely ready.

What Does Exchanging Contracts Mean?

Exchange of contracts is the point at which the buyer and seller become legally committed to the transaction.

Before exchange, either party can usually withdraw or renegotiate.

After exchange, walking away can have serious financial and legal consequences.

The Government’s guide to transferring ownership when selling a home explains that the agreement becomes legally binding once contracts are exchanged.

This is also when the agreed completion date becomes fixed.

That distinction matters because exchange and completion are not the same thing.

Exchange

Both sides legally commit to the transaction and agree the completion date.

Completion

The remaining purchase money is transferred, ownership changes and the buyer receives the keys.

Think of exchange as the commitment and completion as the actual move.

When Do Sellers Exchange Contracts?

A seller is normally ready to exchange once their conveyancer is satisfied that the contract can proceed and the buyer’s side is also ready.

That generally means:

• The contract terms have been agreed.
• Both parties have signed the necessary documents.
• The buyer has a formal mortgage offer where required.
• Searches have been completed.
• Legal enquiries have been dealt with.
• Any survey-related negotiations have been resolved.
• The buyer’s deposit arrangements are in place.
• The fixtures and fittings position is clear.
• A completion date has been agreed.
• Every linked transaction in the chain is also ready.

Your conveyancer will ask for your authority before exchanging.

You do not normally meet the buyer and physically swap contracts across a table. The conveyancers handle the exchange process and then confirm that it has taken place.

MoneyHelper’s guide to exchange and completion also provides a useful checklist of the points normally resolved before buyers and sellers become legally committed.

Signing a Contract Is Not the Same as Exchanging

This catches quite a few sellers out.

Your solicitor may ask you to sign the contract well before exchange takes place.

Signing simply means the document is ready for your conveyancer to use when the transaction reaches the appropriate stage.

You are not legally committed simply because you have signed it.

Exchange only occurs once the conveyancers formally exchange contracts.

That is why sellers should be cautious about making expensive or irreversible moving arrangements based purely on having signed paperwork.

Until exchange has been confirmed:

• The buyer can still withdraw.
• The seller can still withdraw.
• The completion date can change.
• Problems elsewhere in the chain can still delay the move.

Our guide to how long conveyancing takes explains what is usually happening during the weeks between accepting an offer and reaching exchange.

What Happens to the Deposit at Exchange?

The buyer will usually provide an exchange deposit through their conveyancer.

A deposit of 10% of the purchase price is common, but the actual amount can sometimes be lower where this has been agreed between the parties.

This frequently happens in property chains, where a buyer may be relying on the deposit received from their own sale.

Your conveyancer will explain how the deposit is being handled in your particular transaction.

This exchange deposit is different from the buyer’s overall mortgage deposit.

For example, someone buying with a 15% mortgage deposit does not necessarily transfer that entire amount to the seller at exchange.

The legal arrangements should always be confirmed with the conveyancer rather than assumed.

How Long Before Exchange?

There is no reliable universal answer.

A sale may move quickly where:

• The buyer is chain-free.
• Both conveyancers are instructed promptly.
• The buyer has their mortgage arranged.
• Searches return quickly.
• The survey raises no significant issues.
• The title is straightforward.
• Both sides respond promptly.

It may take longer where:

• Several properties are linked in a chain.
• Mortgage approval is delayed.
• Legal enquiries uncover an issue.
• Planning or building regulation paperwork is missing.
• A survey requires further investigation.
• The property is leasehold.
• Probate or another legal issue is involved.
• One party has not yet found an onward property.

Current GOV.UK guidance says the overall process of selling a home can take several months and may take longer where a property chain is involved.

Rather than becoming fixated on a particular week, ask what is actually outstanding.

That gives you a far better picture of how close the transaction is to exchange.

Property Chains Often Decide the Exchange Date

You may be completely ready to exchange and still have to wait.

That is because everyone in a property chain normally needs their linked sale and purchase to be ready at roughly the same time.

Imagine:

1. A first-time buyer is purchasing your buyer’s home.
2. Your buyer is purchasing yours.
3. You are purchasing another property.
4. Your seller is moving elsewhere.

One unresolved mortgage, legal enquiry or completion-date disagreement can affect every household.

This is why knowing only the progress of your own sale is not enough.

At Property Bee, sales progression involves keeping an eye on the wider chain, speaking with buyers, conveyancers and other estate agents to establish what has been completed and what is still holding things up.

Our guide to managing a property chain explains this process in more detail.

Leasehold Properties Can Need More Preparation

Leasehold transactions often involve additional paperwork.

The buyer’s solicitor may need information relating to:

• The lease
• Service charges
• Ground rent
• Buildings insurance
• Major works
• Management arrangements
• The freeholder
• Any residents’ management company

Much of this information comes from a freeholder or managing agent rather than directly from the seller.

That additional party can introduce another potential delay.

If you are selling a leasehold property, instructing your conveyancer early and understanding how the management information is obtained can save valuable time later.

How Is the Completion Date Chosen?

The completion date must normally be agreed before contracts are exchanged.

Your own preference matters, but so does everybody else’s.

Factors may include:

• Removal-company availability
• Work commitments
• School arrangements
• Mortgage deadlines
• Rental notice periods
• The needs of other people in the chain

There is no rule saying completion must happen on a Friday.

Friday remains popular because people have the weekend to unpack, but that popularity can also mean removals companies are busier.

A midweek completion can sometimes be easier to arrange.

MoneyHelper says the period between exchange and completion is commonly around 7 to 28 days, although buyers and sellers can agree a different period.

Can Exchange and Completion Happen on the Same Day?

Yes.

Simultaneous exchange and completion can work particularly well in some chain-free transactions.

However, it removes the certainty normally created by having a period between the two stages.

If something prevents exchange that morning, removals, travel arrangements and practical plans can all be affected immediately.

For sellers in a longer chain, some time between exchange and completion usually gives everyone greater certainty to organise their move.

There is no single correct gap.

Your conveyancer should advise on what is appropriate for your transaction.

Why Does Exchange Get Delayed?

Sometimes a seller hears:

> “We’re nearly ready to exchange.”

Then another week passes.

This does not necessarily mean something has gone wrong.

Common causes include:

• An unanswered legal enquiry
• A missing planning or building regulation document
• A delayed mortgage offer
• Outstanding searches
• A survey issue
• Leasehold management information
• A completion date nobody can agree on
• Another transaction elsewhere in the chain

This is where useful sales progression becomes important.

An estate agent cannot provide legal advice or force a conveyancer or lender to move faster.

What they can do is establish:

• What is outstanding?
• Who is responsible for it?
• Has it actually been requested?
• When is the next update expected?
• Is another part of the chain waiting too?

Sometimes the most useful phone call is simply discovering that two people thought they were waiting for each other.

How Can Sellers Help Reach Exchange Faster?

You cannot control every part of conveyancing, but you can make sure you are not creating an avoidable delay.

Instruct Your Conveyancer Early

Ideally, choose your conveyancer before or around the time the property is marketed.

They can begin identity checks and prepare for the legal work before a buyer is found.

Return Forms Promptly

Complete property information and fittings and contents forms carefully.

Do not rush them, but do not leave them sitting unanswered for a fortnight either.

Gather Paperwork

Useful documents might include:

• Planning permissions
• Building regulation approvals
• Guarantees
• Electrical certificates
• Window documentation
• Boiler records
• Extension paperwork
• Solar-panel documentation

Not every home will have all of these.

The important thing is locating whatever genuinely applies to your property.

Mention Unusual Issues Early

Tell your conveyancer about matters such as shared access, alterations, private roads, restrictive covenants or other known complications.

A problem raised early is generally easier to deal with than one discovered immediately before exchange.

Do Not Make Firm Moving Commitments Too Early

It is completely understandable to start planning ahead.

However, completion is not fixed until exchange.

Be cautious about:

• Non-refundable removal bookings
• Giving rental notice
• Committing to deliveries
• Booking tradespeople at the new property
• Making arrangements that cannot be changed

You can gather quotes and make provisional plans.

Just make sure you understand the cancellation terms.

If you are also purchasing another home, confirm with your conveyancer and lender when insurance needs to begin on that property.

Our guide to whether you should sell before buying also looks at some of the practical decisions involved in managing an onward move.

What Happens Immediately After Exchange?

Once your solicitor confirms that exchange has happened, the uncertainty reduces considerably.

You can now work towards the agreed completion date with much greater confidence.

Typical jobs include:

• Confirming removals
• Finishing your packing
• Arranging utility changes
• Organising keys
• Preparing the property for handover
• Making arrangements for your onward property

The home must be left in the condition agreed within the contract.

The fittings and contents form should also reflect what is staying and what is being removed.

If something changes after exchange, speak to your conveyancer rather than relying on an informal agreement with the buyer.

Exchange Is Where the Sale Becomes Real

For sellers, exchange is one of the biggest milestones of the entire move.

An accepted offer is important, but exchange is the point at which buyer and seller become legally committed and the completion date becomes certain.

Getting there depends on more than repeatedly asking whether the solicitors are ready.

It means preparing the paperwork early, dealing with enquiries properly, keeping the property chain visible and making sure everyone understands what is still outstanding.

At Property Bee, our involvement does not stop when we agree the sale.

We continue progressing transactions across Surrey, Hampshire and Berkshire, keeping communication moving between buyers, sellers, conveyancers and other agents as the chain works towards exchange and completion.
