What Happens on Completion Day When You Sell Your House? A Seller's Checklist

Introduction: The Day Your Sale Becomes Real

Completion day is the day everything comes together. After weeks or months of conveyancing, enquiries, searches, and waiting, this is the day legal ownership of your home transfers to the buyer. The funds arrive, the keys are handed over, and your sale is done.

For sellers, it can feel like a blur. There is a lot happening in the background through your solicitor, practical tasks to manage on the ground, and often the stress of a simultaneous move. Understanding exactly what happens and in what order removes much of the anxiety and helps you prepare so the day runs smoothly.

This guide covers everything a seller needs to know about completion day in England and Wales. It explains what your solicitor does, what you are responsible for, what the timing looks like hour by hour, what can go wrong and how to handle it, and what needs to happen after the keys have been handed over. It also includes a practical room-by-room and task-by-task checklist you can use in the days leading up to the day itself.

Before completion day arrives, make sure you know exactly what your net proceeds will be. Use the free Cost Saving Calculator on YooSell to understand how much you keep after selling costs before the completion statement lands on your doormat.

What Completion Day Actually Means

Completion is the final legal step in a residential property sale in England and Wales. It is the moment at which ownership of the property transfers from the seller to the buyer, the balance of the purchase price is paid, any outstanding mortgage is redeemed, and the buyer gains the right to move in.

What Happens Legally on Completion Day

On completion day, the buyer's solicitor transfers the balance of the purchase price to your solicitor using the CHAPS same-day payment system. CHAPS is the payment network used by conveyancers for property transactions because it guarantees same-day cleared funds.

Once your solicitor receives and confirms the funds, completion occurs. Your solicitor will then release authority for the keys to be handed over, redeem your outstanding mortgage if you have one, pay their own fees, and transfer the net sale proceeds to your nominated bank account.

Completion does not happen the moment the buyer's solicitor sends the money. It happens the moment your solicitor receives and confirms it. This distinction matters for timing, particularly when there is a chain.

What Completion Is Not

Completion day is not the same as exchange of contracts. Exchange, which typically happens one to four weeks before completion, is the point at which the transaction became legally binding. By completion day, both sides are already committed and neither can withdraw without serious financial and legal consequences.

Completion day is also not always the day you physically move all your belongings. While in most sales it coincides with the physical move, it is entirely possible to have moved out a day or more before completion day, leaving the property empty and ready for the buyer from the moment completion is confirmed.

The Difference Between Exchange and Completion

Understanding the gap between exchange and completion helps you plan the whole final period of your sale.

What Exchange Means for a Seller

Exchange is the moment that makes the sale legally binding. Before exchange, either party could walk away without penalty, though both would lose the costs they had already incurred. After exchange, you are committed to selling on the agreed completion date. If you fail to complete, the buyer can take legal action and you may be liable for their costs and losses.

At exchange, the buyer pays a deposit, typically ten percent of the agreed purchase price, to your solicitor. This deposit is held until completion. The completion date is written into the contract at exchange.

The Period Between Exchange and Completion

The gap between exchange and completion is typically between one and four weeks, though it can be agreed further ahead if the parties need time for removal bookings, notice periods on rented accommodation, or other practical arrangements.

Once exchange has taken place, you can make firm removal bookings, notify utility companies, confirm your forwarding address, and begin the final stages of preparing to leave the property. All the arrangements you would not make with certainty before exchange, because the date was not yet fixed, can now be confirmed.

What Your Solicitor Does on Completion Day

The legal and financial work of completion day is handled by your solicitor. You do not need to be present at their office. You need to be reachable by phone throughout the day, with your phone charged and notifications on.

Early Morning: Final Checks and Preparations

Your solicitor begins the day by making final checks. They confirm the completion statement is correct, check that the mortgage redemption figure is current and accurate, and confirm they are ready to receive funds. They communicate with all solicitors in the chain to confirm everyone is on track to complete that day.

Your solicitor will also verify the CHAPS bank details for all transfers, including the account details for your mortgage redemption, their own fees, and your net proceeds. Bank detail fraud has been a persistent problem in property transactions, and solicitors are required to verify account details carefully before any transfer is made.

Mid-Morning: Funds Begin Moving Up the Chain

In a chain of transactions, the money starts moving at the bottom and works its way up. The buyer at the bottom of the chain, who is typically a first-time buyer using a mortgage, has their funds sent by their mortgage lender to their solicitor. That solicitor then transfers the completion funds to the next solicitor in the chain, and so on up until your own buyer's solicitor sends the balance of the purchase price to you.

If you are selling as part of a chain, this process means your completion tends to happen later in the day than a chain-free sale. A first-time buyer chain of two transactions might complete by late morning. A longer chain might not confirm completion until mid-afternoon.

Completion Confirmed: Keys Released and Mortgage Redeemed

Once your solicitor receives and confirms the completion funds, they take three immediate steps.

First, they authorise the release of the keys. They will notify the estate agent or platform through which you sold the property that completion has occurred and that the buyer can collect the keys. If you are handing the keys over directly rather than through an agent, your solicitor will notify you that it is safe to do so.

Second, your solicitor uses part of the completion funds to redeem your outstanding mortgage. They transfer the exact redemption amount to your mortgage lender. The lender will then release the charge registered on the title to allow the buyer's solicitor to register the new ownership at HM Land Registry.

Third, your solicitor deducts their own fees and any other agreed deductions from the completion funds and transfers the net proceeds to your nominated bank account.

When You Receive Your Money

Your net proceeds typically arrive in your bank account on completion day itself, usually in the afternoon once all the transfers have been processed. If completion is confirmed late in the afternoon, the funds may not clear until the following working day. Your solicitor should have discussed the likely timing with you in advance.

Check your completion statement carefully a day or two before completion day so you know exactly what figure to expect. The net proceeds are the agreed sale price minus the deposit already held, the mortgage redemption amount, your solicitor's fees, and any other agreed deductions.

What You Are Responsible for on Completion Day

While your solicitor manages the legal and financial side, you have a set of practical responsibilities on completion day that are entirely yours to manage.

Vacate the Property on Time

You are legally required to give vacant possession of the property to the buyer on completion day. This means the property must be empty of your belongings and you must have left by the agreed time. In most contracts, vacant possession is required by 1pm. Some contracts specify a different time, so check your own.

Planning to be out earlier than the contractual deadline is always the better approach. Completion day is invariably busier than anticipated. Removal vans run late, last-minute items are discovered, and the practical reality of moving rarely matches the plan. Building a buffer of at least an hour before your contractual deadline protects you if anything takes longer than expected.

Hand Over All Keys

Every key that belongs to the property must be handed over. This is a point that catches sellers off guard more often than you would expect. Keys accumulate in drawers and on keyrings over years of ownership. Before completion day, do a thorough audit of every key associated with the property.

The keys to hand over include front door keys and all spares, back door and side gate keys, garage and outbuilding keys, communal entrance keys for flats, post box keys, window keys, and any keys to internal rooms or cupboards that have separate locks.

Leave all keys at the estate agent's office or platform collection point, or hand them directly to the buyer if that has been agreed. Do not take any keys away with you. If a key is missing after you have left, the buyer will be justified in claiming the cost of a locksmith from you.

Take Meter Readings

Before you leave the property for the last time, take meter readings for gas, electricity, and water. Photograph the meters to create a timestamped record. These readings are essential for giving your final utility bills accurate closing dates and for making sure you are not charged for energy used after completion.

Notify each utility provider with your closing reading and your forwarding address as soon as possible on or after completion day.

Leave Agreed Items Behind

Check your TA10 Fixtures, Fittings and Contents Form one final time before you leave to confirm that everything agreed to be included in the sale is still in the property. Light fittings, appliances, window dressings, and any other items specified in the TA10 must be left.

If you agreed to leave specific items such as white goods, garden furniture, or built-in storage, confirm they are present and in the condition in which they were agreed to be left. Items that were agreed to stay and are found missing on the buyer's arrival give the buyer grounds to withhold completion or claim the cost of replacement.

Leave the Property in the Agreed Condition

The property should be left in substantially the same condition it was in when the buyer's final inspection was carried out, typically at exchange or a formal visit shortly before completion. This does not mean it needs to be professionally cleaned, but it should be empty of your belongings, free from damage not already noted, and not left in a state that materially differs from when the buyer agreed to proceed.

Some sellers arrange a professional end-of-tenancy style clean before completion as a courtesy. This is not legally required but is widely appreciated by buyers and can avoid any dispute about the condition of the property.

The Hour-by-Hour Completion Day for Sellers

Understanding the typical progression of the day helps you plan around it.

Early Morning: Load and Prepare

By early morning on completion day, the bulk of your packing and loading should already be done. Completion day is not the time to be starting the packing process. Professional removal companies are typically booked to arrive early in the morning and will expect much of the loading work to have begun the previous day.

Use the early morning to take meter readings, photograph every room for your own records, do a final check through every room and cupboard for missed items, and collect any documents and manuals you plan to leave for the buyer.

Mid-Morning: Waiting for Confirmation

The mid-morning period on completion day is typically the quietest from a practical standpoint but the most anxious. You may be sitting in a partly empty property or a removal van outside, waiting for your solicitor to confirm that completion has occurred.

Keep your phone accessible and charged. Your solicitor may need to contact you quickly if any last-minute issue arises, or to confirm completion as soon as it is through.

Midday to Early Afternoon: Completion Confirmed

For a chain-free sale or a short chain, completion is frequently confirmed between 11am and 1pm. For longer chains, confirmation may come as late as 2pm or occasionally later. The contractual deadline for completion is 2pm in most standard contracts. If completion has not occurred by 2pm, the transaction technically enters default and compensation clauses under the Standard Conditions of Sale may be triggered.

Once your solicitor confirms completion, hand over the keys immediately to the agreed party. Leave the property. You no longer own it.

Afternoon and Evening: After Completion

Once the keys are handed over, your attention shifts to your own move. If you are purchasing another property, your buyer's funds should have allowed your own purchase to complete either simultaneously or shortly after. Your new keys will be released once your purchase completes in the same way.

Check your bank account that afternoon for the net proceeds. If they have not arrived by close of banking, contact your solicitor. In most cases the money clears the same day but if completion happened late it may be the following working day before it settles.

Selling as Part of a Chain on Completion Day

Selling within a chain adds complexity to completion day that is worth understanding clearly.

Why Chains Take Longer to Complete

In a chain of transactions, every buyer's funds must be sent from the bottom of the chain upward before any completion can occur. Each transfer takes time. If the chain has four transactions, there are four sequential fund transfers before the seller at the top of the chain receives their money.

This means that in a chain, the party at the top of the chain, typically the seller who is not buying onwards, receives their money last. A four-property chain might not fully complete until mid to late afternoon even if everything goes smoothly.

What Happens If One Part of the Chain Has a Problem

If any party in the chain encounters a problem on completion day, such as a mortgage advance arriving late, a solicitor being unable to verify a transfer, or any other technical or administrative delay, every completion above that point in the chain is held up.

This is why completion day in a chain can be stressful even when your own transaction is straightforward. You have no control over what happens in other transactions. The best protection is to have a solicitor who communicates proactively throughout the day and who chases progress rather than waiting passively.

Planning Your Removal Around Chain Timing

If you know you are in a long chain, plan your removal company booking around a later completion. Booking a removal company for a full day gives you flexibility. If you book for a half day in the morning expecting early completion and it does not happen until late afternoon, you may face additional removal costs or practical chaos.

What Can Go Wrong on Completion Day and How to Handle It

Most completion days proceed smoothly. But some do not, and knowing what can go wrong helps you stay calm and respond effectively if it does.

Late or Missing Funds

The most common completion day problem is funds arriving later than expected. This is usually caused by a bank transfer taking longer than anticipated, a mortgage lender releasing funds late, or a delay somewhere in the chain. In most cases it resolves the same day.

If your solicitor has not confirmed completion by 1pm and your contractual deadline is 2pm, call them. Do not wait passively. Ask specifically what stage the funds are at and what the expected confirmation time is.

Technical Issues with Bank Transfers

CHAPS transfers occasionally encounter technical issues. Banks have cut-off times for same-day processing, and if a transfer misses the cut-off it may not clear until the following working day. This is rare but does happen. Your solicitor should communicate clearly if this is the risk, because it may mean you need to make temporary arrangements for that night.

Disputes About the Property Condition or Missing Items

If the buyer arrives to find the property is not in the expected condition, or that items agreed to be included in the TA10 are missing, they may contact their solicitor to raise a withholding claim. This can delay key release even after the funds have cleared.

The prevention is straightforward: leave everything agreed in the TA10, leave the property in a reasonable condition, and do a final walkthrough immediately before leaving to confirm everything is as it should be.

Mortgage Redemption Delays

If your solicitor encounters any issue with the mortgage redemption, such as an incorrect redemption figure or a lender processing delay, this can hold up the release of your net proceeds even after completion has occurred. Ensuring your solicitor has had the confirmed redemption figure from your lender in writing well in advance of completion day avoids most of these issues.

The Complete Seller's Checklist for Completion Day

Two Weeks Before Completion Day

Confirm your removal company booking and your loading schedule for the day before and the morning of completion. Make sure they have a contingency plan if completion is delayed.

Notify your children's school, your employer, your GP, your dentist, HMRC, your bank, and any subscriptions and delivery services of your change of address. It is easier to do this in stages over a fortnight than to try to do everything on the day.

Arrange mail redirection through Royal Mail so any post sent to your current address is forwarded to your new one for at least a year.

Check your completion statement from your solicitor for accuracy and confirm the expected net proceeds amount.

Confirm that your EPC, all building certificates, and any guarantees or warranties you have provided during conveyancing have been passed to your solicitor.

One Week Before Completion Day

Begin packing rooms that are not in daily use. A property that is largely packed before completion day is far easier to manage on the day itself than one where packing only begins the morning of the move.

Confirm your solicitor has your correct bank account details for the net proceeds transfer. This confirmation should be done directly with your solicitor, not via email, because email interception fraud involving bank details is a known risk in property transactions.

Confirm your key handover arrangements. If you are leaving keys with the estate agent or platform, confirm the location and timing. If you are handing over directly, confirm the arrangement with the buyer.

Start running down perishable food. Begin clearing garage, attic, and outbuilding storage.

The Day Before Completion Day

Complete as much of the removal loading as possible. Many removal companies will load the van in the evening for a morning move. This reduces the amount of work required on completion day itself.

Do a thorough check through every room, cupboard, loft hatch, and outbuilding for any items not yet packed.

Collect all sets of keys and label them clearly. Place them somewhere you will not forget them, such as by the front door.

Confirm your solicitor is ready to proceed the following day and ask whether there are any outstanding issues that might affect timing.

Completion Day Morning

Take metre readings for gas, electricity, and water. Photograph each metre clearly. Note the time and date.

Photograph every room in the property, including any areas where wear or damage exists, for your own records. This protects you against any retrospective claim about the property's condition.

Do a final walkthrough of every room to confirm all agreed items are present, all non-agreed items are removed, and nothing has been accidentally left behind.

Leave any instruction manuals, appliance guides, alarm codes, and relevant documentation for the buyer in a visible place, typically in the kitchen.

Keep your phone charged and accessible all morning.

Once Completion Is Confirmed

Hand over all keys to the agreed party or location immediately upon confirmation from your solicitor.

Leave the property. Do not re-enter the property after the keys have been handed over. You no longer own it and your right to access ended at the moment of completion.

Contact your utility providers with your closing metre readings and your forwarding address.

Check your bank account later in the day for the net proceeds. If they have not arrived by close of banking, contact your solicitor.

If you are also purchasing, confirm with your own solicitor that your purchase has also completed and that your new keys have been released.

After Completion Day

Review your completion statement against the actual net proceeds received and confirm all figures match.

Cancel any contents or buildings insurance on the property you have sold. Your insurer should be notified promptly.

Notify the council tax office that you have moved out of the property so you are not billed for council tax from completion day forward.

Keep all completion documents, including the completion statement, the signed contract, and any correspondence, in a safe place. You may need them for capital gains tax purposes if the property was not your main home.
