There are few more helpless feelings than sitting beside a loaded removal van while somebody tells you that the completion money has not arrived.
Your old home may be empty, your new home may be tantalisingly close and the contents of the kettle box may already be a matter of urgent interest. Meanwhile, a bank transfer somewhere in the chain is refusing to cooperate.
I remember how quickly a routine moving day can become stressful once nobody seems able to tell you what is happening. But the first thing to establish is whether completion is simply running late or whether the contractual completion date is genuinely going to be missed.
Those are not necessarily the same thing.
Quick answer: Once contracts have been exchanged, a buyer or seller who fails to complete in accordance with the contract will generally be in breach. The contract does not normally end automatically. The defaulting party may have to pay contractual compensation and may also be liable for additional financial losses caused by the delay. The innocent party may serve a notice to complete and, if that notice is not complied with, much more serious remedies can follow.
A payment arriving late in the afternoon is different from a buyer who no longer has the funds or a seller who cannot give vacant possession. Completion may still happen later that day, although the contract can impose financial consequences for the delay.

What does delayed completion mean?
Completion is the stage at which the balance of the purchase money is paid to the seller’s conveyancer and the transaction is completed. The buyer can then normally take possession and the keys are released.
My separate guide explains what happens on completion day and when you get the keys.
The expression “delayed completion” is commonly used for three rather different situations.
Completion is running late during the day
The buyer’s conveyancer may have sent the money, but it has not yet appeared in the seller’s conveyancer’s account.
At 11am, that can be frustrating. By mid-afternoon, with removal companies waiting and several transactions depending on the same money, it can feel rather more serious.
But the sale may still complete that day.
The seller’s conveyancer cannot normally authorise release of the keys merely because they have been told that a payment has been sent. They need to know that the completion money has actually been received.
Completion will not happen on the agreed day
This is different.
The mortgage money may be unavailable. The buyer may not have the balance needed to complete. The seller may still have an occupier in the property or may be unable to transfer the title required by the contract.
If the problem cannot be resolved on the contractual completion date, the legal consequences of default become much more important.
The transaction was delayed before exchange
A slow house purchase is not necessarily a case of delayed legal completion.
Before exchange, the parties may have spent weeks discussing a proposed moving date without being contractually committed to it.
The position normally changes at exchange of contracts. Once contracts are exchanged, the agreed completion date is no longer simply the date everybody hopes to move. It is part of a binding contract.
Is delayed completion a breach of contract?
Usually, yes, where a party fails to perform the obligations required of them for completion.
The buyer must provide the money due under the contract. The seller must be able to transfer the property and, where vacant possession has been promised, provide it.
A failure can amount to a breach even where nobody intended anything to go wrong.
A buyer might be in default because the mortgage lender has failed to release funds in time. A seller might be in default because a tenant or family member has not left the property.
That can seem harsh, particularly where the person affected has spent the whole day desperately trying to solve somebody else’s mistake. But contractual responsibility and personal blame are not the same thing.
If a bank, lender, conveyancer or other third party caused the problem, there may later be a separate question about whether that organisation is responsible for the resulting loss. It does not necessarily change the immediate contractual position between buyer and seller.
Many residential contracts incorporate the Law Society’s Standard Conditions of Sale. They are not compulsory and they can be amended, so the particular contract must always be checked.
Why is conveyancing completion delayed?
Completion depends on several things happening in the correct order, often across several separate transactions.
The common problems are surprisingly mundane.
The mortgage advance has not arrived
The buyer’s lender may release the mortgage funds later than expected, discover that a condition of the mortgage offer has not been satisfied or encounter an administrative problem.
A mortgage offer that has expired or been withdrawn is much more serious. The buyer may no longer have the money needed to complete at all.
The bank transfer is taking longer than expected
Completion money is usually sent electronically. A same-day transfer is not necessarily an instantaneous one.
Security checks, manual authorisation or other banking processes can hold up a large payment.
I have never known repeated telephone calls to make a bank transfer travel faster, although that rarely stops anybody trying.
The buyer’s own money is not available
A buyer may encounter a bank transfer limit, discover that money moved from another account has not cleared or simply misunderstand how much they were required to send.
This is why the balance requested on the completion statement should normally be transferred to the conveyancer in good time rather than on moving morning.
Another transaction in the chain is late
A buyer who is also selling may need the money from their sale to fund the purchase.
If their own buyer’s money arrives late, they cannot send the purchase money onwards. One delayed transaction can therefore work its way up an entire chain.
The seller cannot give vacant possession
Where vacant possession has been contracted for, the seller needs to be able to hand the property over as agreed.
A tenant who refuses to leave, a family member still occupying the house or substantial belongings left behind can create a problem.
Simply being a little slow with the removal van does not necessarily derail the transaction, but a seller cannot assume that they are entitled to remain in occupation after completion because packing took longer than expected.
A legal requirement has not been satisfied
A transfer may be incorrectly signed, an essential document may be missing or a last-minute title or mortgage issue may prevent the conveyancer from completing safely.
The fact that a removal van is outside does not allow a conveyancer to ignore a legal or lender requirement.
What happens if the completion money arrives after 2pm?
Two o’clock has acquired rather more mythology in conveyancing than it deserves.
Under the unamended Standard Conditions of Sale, if the completion money is received after 2pm, completion is treated as taking place on the next working day for certain contractual purposes, including calculating compensation for late completion.
That does not mean the doors slam shut at 2.01pm and nobody can complete until tomorrow.
If the money arrives later that afternoon and the seller’s conveyancer is able to complete, the transaction can still be completed and the keys released.
The Standard Conditions also make an important exception where the property is sold with vacant possession and the buyer was ready to complete but delayed payment because the seller had not vacated by the relevant time.
The contract can substitute another completion time for 2pm. In chains, an earlier time is sometimes agreed to give money time to move through subsequent transactions.
So the right question is not simply, “Is it after 2pm?” It is, “What does this particular contract say, and who is responsible for the delay?”
What should you do if completion is delayed?
When the anxious telephone call arrives, the most useful question is usually:
“What exactly is preventing completion, and can it still be resolved today?”
Ask your conveyancer whether the completion money has been sent, whether it has arrived, whether the problem lies elsewhere in the chain and whether completion is still realistically expected that day.
An estate agent can be useful in finding out what is happening elsewhere in the chain, but the legal confirmation of completion must come through the conveyancers.
Do not collect the keys unless completion has been confirmed
A buyer should not enter the property merely because the seller has left and the estate agent happens to be holding the keys.
Likewise, the estate agent should not release them until authorised.
If occupation before completion is being considered as a solution to a longer delay, it needs proper thought. My separate guide explains when a licence to occupy before completion may be possible.
Speak to the removal company
Find out about waiting charges, overnight storage and what would happen if the move has to be postponed until the next working day.
Take sensible steps to keep the costs down. Someone claiming damages for breach of contract is expected to mitigate their loss rather than allow avoidable expenditure to accumulate.
Keep the evidence
Keep invoices and receipts for storage, removals, hotel accommodation, additional travel and other expenditure caused by the delay.
A simple note of what happened and when can also be useful. Six weeks later, “the removal company charged us something extra” is much less helpful than an invoice and a clear timeline.
Do not forget the insurance
Where the contractual risk has already passed to the buyer, buildings insurance should remain in force while the transaction is unresolved.
If the property is unexpectedly going to remain empty or occupation arrangements change, tell the insurer.
My guide to house insurance on exchange of contracts explains why insurance can matter before the buyer has the keys.
Who pays when completion is delayed?
The short answer is: usually the party whose default caused the delay, but the precise financial consequences depend on the contract and the loss actually suffered.
There are two distinct questions. The contract itself may require compensation for late completion, and the innocent party may also have suffered additional financial losses for which damages can be claimed.
Contractual compensation
Under the Standard Conditions of Sale, where one or both parties are in default and completion is delayed, the party whose total period of default is greater pays compensation to the other.
If the buyer is the paying party, the calculation is generally made by applying the contract rate to the purchase price less any deposit already paid for the relevant period of default.
The phrase “penalty interest” is often used informally, but contractual compensation is more accurate. It is not simply a fine imposed because somebody had a bad day.
The contract rate should be checked rather than guessed. Where the contract uses the Law Society rate, the current figure can be found on the Law Society’s Law Society interest rate page. A special condition may specify something different.
Additional financial losses
Contractual compensation does not necessarily prevent a separate claim for loss caused by the delay.
Under the Standard Conditions, compensation already paid is taken into account so that the innocent party does not recover twice for the same loss.
Depending on the circumstances, recoverable losses might include:
- extra removal-company charges;
- overnight storage;
- reasonable temporary accommodation;
- additional travel;
- extra mortgage, bridging or lender costs; and
- recoverable liabilities arising from a connected sale or purchase.
The important word is recoverable. Not every expense caused by a miserable moving day automatically becomes the other party’s responsibility.
The loss must have been caused by the breach, must not be too remote and must have been reasonably incurred. The innocent party must also take reasonable steps to minimise it.
A receipt for £280 of overnight storage tells you something. A general assertion that the whole experience “cost thousands” does not.
The stress and inconvenience can be considerable, but an ordinary contractual claim will generally focus on provable financial loss rather than compensation simply for the disruption itself.
What happens when the delay is in a property chain?
This is where liability can feel counter-intuitive.
Each sale in a chain is a separate contract.
Suppose Alex is buying from Beth, and Beth is buying from Chris. Alex fails to complete, so Beth does not receive the money she needs for her purchase from Chris.
Beth may still be in breach of her contract with Chris even though Alex caused the original problem.
Chris’s contractual claim is generally against Beth, not Alex. Beth may then seek to recover the appropriate loss from Alex.
This is how one delayed payment can create a series of claims moving down a chain.
It does not mean that every cost eventually lands automatically on the person who caused the first delay. Each claim still has to satisfy the ordinary rules concerning causation, foreseeability, mitigation and proof.
And unless the contract says otherwise, “my buyer didn’t pay me” is not normally a complete answer to your own seller when you have separately promised to complete your purchase.
What is a notice to complete?
Missing the contractual completion date does not normally bring the sale to an automatic end.
The contract remains alive and both parties remain obliged to complete.
Under the Standard Conditions, once the applicable completion time has passed on the contractual completion date, a party who is ready, able and willing to complete can serve a notice to complete.
That requirement matters.
A buyer cannot complain that the seller has failed to complete while the buyer is themselves unable to produce the purchase money. Likewise, a seller serving notice must be in a position to perform the seller’s side of the transaction, subject to the contractual terms.
How long does a notice to complete give?
Under the unamended Standard Conditions, the notice requires completion within 10 working days, excluding the day on which the notice is given.
During that period, time becomes “of the essence”. Put more simply, the new deadline is a hard one.
Contractual compensation can continue to accrue while completion remains outstanding.
What happens to the buyer’s deposit?
Where the buyer has paid less than a 10% deposit, the Standard Conditions can require the buyer, on receiving a notice to complete, to pay the amount needed to bring the deposit up to 10% of the purchase price. If no deposit has been paid, the full 10% may become payable.
That is one reason a notice to complete is not simply a stern letter from the conveyancer.
Does a notice have to be served immediately?
No.
If everyone knows that the missing mortgage money should arrive tomorrow morning, preserving the transaction by agreeing a short extension may be more sensible than immediately escalating matters.
But any agreement to vary the completion arrangements should be dealt with through the conveyancers and recorded clearly. Informal assurances can create unnecessary arguments about whether rights have been waived or the contract varied.
What happens if the buyer fails to complete?
A buyer may fail to complete because mortgage funding has disappeared, their own sale has not produced the money expected or they have simply decided they no longer want the property.
Changing your mind after exchange does not undo the contract.
While the contract remains in force, the buyer is still required to complete and may owe compensation for the period of default.
If a valid notice to complete is served and the buyer still fails to comply, the Standard Conditions give the seller much stronger remedies.
The seller may be entitled to rescind the contract, forfeit and retain the deposit and accrued interest, resell the property and claim damages.
If the house later sells for less, the difference in price may form part of the seller’s claim, subject to the ordinary rules governing damages and credit being given so that the seller does not recover twice for the same loss.
For a buyer who has exchanged without secure funding, the financial consequences can therefore be much larger than simply losing the money already handed over.
What happens if the seller fails to complete?
A seller may be in default because they refuse to proceed, cannot give the promised vacant possession or are unable to transfer the title required by the contract.
A buyer who is ready, able and willing to complete may serve a notice to complete.
If the seller then fails to comply with the notice, the buyer may be entitled to rescind the contract, recover the deposit with accrued interest and claim damages for recoverable loss.
But ending the contract is not necessarily the only possible remedy.
A buyer who still wants the property may, in an appropriate case, seek specific performance, which is a court order requiring the seller to perform the sale contract. It is a discretionary remedy and a very different course from accepting that the transaction is over.
Where a seller is genuinely refusing or unable to complete, individual legal advice becomes important quickly.
Can the completion date be changed after exchange?
Yes, if buyer and seller agree.
The fact that a completion date is contractually binding does not prevent the parties from later varying their agreement.
But one party cannot normally impose a new date on the other simply because the original date has become inconvenient.
The variation should be handled by the conveyancers. In a chain, several connected transactions may need to be altered together.
The mortgage lender may also need to be considered, particularly if funds have already been released or the mortgage offer is close to expiry.
A properly agreed new date can be a sensible solution. What is dangerous is everyone informally behaving as though completion has moved while the written contract continues to say something else.
What if completion fails on a Friday?
Friday is popular because people hope to unpack over the weekend. Unfortunately, it is also the least forgiving day for a problem that cannot be fixed before the banks and conveyancers close.
If payment cannot be completed that afternoon, the next practical opportunity may be Monday. A bank holiday can make the gap longer still.
That may mean extra storage, temporary accommodation and complications for several households in a chain.
This does not mean Friday completions should be avoided. Most happen perfectly normally. But an earlier weekday gives more working time to recover if something unexpected goes wrong.
How can completion delays be reduced?
No amount of preparation can prevent every banking problem, but several common risks are avoidable.
Buyers should send their own contribution to the conveyancer early enough for cleared funds to be available before completion and should check bank transfer limits well in advance.
Mortgage conditions and the expiry date of the offer should be dealt with before exchange. Signed transfers, mortgage deeds and other documents should also be returned promptly rather than left until the last moment.
Sellers should plan to provide vacant possession when the contract requires it, not begin thinking about loading the van only after completion has been confirmed.
A sensible period between exchange and completion can also reduce pressure. Exchanging and completing on the same day can work perfectly well, but it removes much of the margin for dealing with a funding or paperwork problem.
And check the practical contracts around the move. Knowing in advance what the removal company charges for waiting or storage is much better than discovering it at 4.30pm with all your furniture on the pavement.
Frequently asked questions
Does delayed completion automatically cancel the sale?
No. Missing the completion date does not normally make the contract disappear. The parties remain bound unless the contract is subsequently rescinded or otherwise brought to an end.
How long can completion be delayed?
There is no universal maximum period before a notice to complete is served. Under the unamended Standard Conditions, once a valid notice has been served it normally requires completion within 10 working days, excluding the day of service.
Can I claim hotel and removal costs?
Potentially. Reasonable costs caused by the breach may be recoverable if they satisfy the ordinary rules for contractual damages. Keep receipts and take sensible steps to minimise the expenditure.
Does a problem elsewhere in the chain excuse me?
Not ordinarily. Each sale is a separate contract. If your buyer’s default prevents you completing your purchase, you may be liable to your own seller while having a separate claim against your buyer.
Can the estate agent release the keys before completion?
Not simply because the buyer is waiting outside. The usual arrangement is that keys are released only after the seller’s conveyancer has confirmed completion and authorised their release.
Can a conveyancer be responsible for a failed completion?
Possibly, if the delay resulted from a failure to exercise reasonable professional care. But the fact that completion went wrong does not itself establish negligence.
The immediate priority is usually to identify the obstacle, complete the transaction if possible and keep the resulting loss to a minimum. Responsibility for what went wrong can then be investigated from the file, correspondence and banking records.
A bad moving day does not always mean a failed purchase
A delay on completion day is serious, but it is not necessarily fatal to the transaction.
A payment can arrive late. A lender can resolve a query. The parties can agree a revised date. Something that feels at lunchtime like a collapsing house move may still end with the keys being released that afternoon or the following working day.
The important distinction is between a temporary operational delay and a party who cannot or will not perform the contract.
The first may require an uncomfortable few hours and some practical rearranging. The second can lead to contractual compensation, damages, a notice to complete and, ultimately, the loss of the transaction itself.
When everything you own is sitting in a removal van, being told to establish exactly what has gone wrong may not feel particularly comforting. But it is the question that matters most.
Is the money simply late, or can somebody no longer complete?
The answer tells you whether you are dealing with a bad afternoon or a much more serious contractual problem.
