Completion day: your complete guide

Conveyancing client guide

What happens on completion day, what to do between exchange and completion, and what happens afterwards, with checklists you can print.

Last reviewed: October 2026

Completion day is the day the property changes hands: the money reaches the seller’s solicitor, ownership passes to the buyer and the keys are released. This guide explains what happens on completion day, what to do before it and what happens afterwards, for buyers and sellers. You can print it and use the checklists as you go.

What completion means

Completion is the final legal step of a purchase or sale. On completion day:

  • the buyer’s money, from their lender and from them, reaches the seller’s solicitor;
  • ownership of the property passes to the buyer;
  • the estate agent releases the keys.

How completion differs from exchange. Exchange of contracts comes first. It is the point where the sale becomes legally binding and the completion date is fixed. Completion is that agreed date, when the money moves and the property changes hands. There is usually a gap of 1 to 4 weeks between the two, but they can happen on the same day.

Keep your money safe in the days before completion. This is when payment fraud is most often attempted, because large sums are about to move.

Between exchange and completion

Once contracts are exchanged, the date is fixed. Use these lists to prepare.

If you are buying

  • Book your removals for completion day.
  • Confirm your buildings insurance is in place from exchange. You are committed from that date, and your lender will require cover by completion at the latest.
  • Pay the balance from your completion statement, as cleared funds, in good time before completion, usually at least two working days before. Your conveyancer will confirm the date.
  • Call us on the number you already have for us to confirm our bank details before you pay.
  • Check your bank’s daily transfer limits, so a large payment is not held up.
  • Agree with the estate agent how and where you will collect the keys.

If you are selling

  • Book your removals for completion day.
  • Plan to leave the property empty by the agreed time, with the fixtures and fittings you agreed to include.
  • Arrange to hand the keys to the estate agent on the day.
  • Keep paying your mortgage as normal until completion.

Everyone

  • Arrange to take meter readings on the day: gas, electricity and water.
  • Tell the council (for council tax), your energy and water suppliers, your broadband provider and your insurers that you are moving.
  • Update your address with your bank, your GP and the DVLA.
  • Arrange for Royal Mail to redirect your post.

On the day

Completion follows the same steps every time, although the timing varies.

  1. Morning: we send the money. If you are buying, we send the purchase money, from your lender and from you, to the seller’s solicitor by same-day bank transfer.
  2. The seller’s solicitor confirms they have received it. At that moment the sale is complete.
  3. The estate agent releases the keys. The seller’s solicitor tells the agent, and the agent hands over the keys.

Many completions happen around midday to early afternoon, depending on the chain. The contract usually sets a latest time for completion on the day, often early afternoon.

Why the keys can come later than you expect. In a chain, the money moves up the chain one link at a time. The buyer at the bottom pays their seller, who then pays for their own purchase, and so on. Nobody can collect keys until the money has reached the seller’s solicitor for that property, so if you are near the top of a long chain, your keys may be released later in the day.

If completion is delayed

Most completions happen on the agreed day, but delays do happen.

Why it happens

  • Money gets held up somewhere in the chain, for example at a lender or a bank.
  • Funds arrive late from a buyer or a lender.

What we do

We track the money, keep in touch with the other solicitors in the chain, and tell you what is happening as soon as we know.

What you can do

  • Stay in touch with your removals firm and the estate agent, and let them know about any delay.
  • Keep your phone to hand so we can reach you.

The consequences of a late completion depend on the terms of the contract. We will explain the position on your own matter.

After completion: if you bought

  • Stamp Duty. We pay your Stamp Duty Land Tax and file the return. The return is due within 14 days of completion. For property in Wales, Land Transaction Tax applies instead, and its return is due within 30 days.
  • Registration. We apply to HM Land Registry to register you as the owner, together with your lender’s charge. Registration can take weeks or many months; HM Land Registry publishes its current processing times.
  • Your title. When registration is complete, we send you a copy of the updated title.
  • Your file. We then close your file.

Our article on what happens after completion explains these steps in more detail.

After completion: if you sold

  • Your mortgage. We repay your mortgage from the sale money on the day.
  • The estate agent. We pay the agent’s fees, as shown on your completion statement.
  • Your balance. We send the balance to the bank account you have already confirmed with us.
  • Your lender’s discharge. Your lender confirms the mortgage is repaid with a form called a DS1, which is sent to HM Land Registry so its charge is removed from the title.
  • Your file. Once that is confirmed, we close your file.

Your moving checklist

One list to print and tick off. Items marked for buyers or sellers apply only to you if you are doing that.

  • Tell the council, energy and water suppliers, broadband provider and insurers that you are moving.
  • Update your address with your bank, your GP and the DVLA.
  • Arrange for Royal Mail to redirect your post.

On completion day

  • Keep your phone to hand so we, the agent and your removals firm can reach you.
  • Sellers: leave the property empty by the agreed time, with the agreed fixtures and fittings.
  • Sellers: hand the keys to the estate agent.
  • Take meter readings for gas, electricity and water, and photograph them.
  • Buyers: collect the keys once we tell you completion has taken place.

After completion

  • Buyers: look out for your copy of the updated title from us.
  • Sellers: check the balance has reached your account.
  • Keep your completion statement and our letters somewhere safe.

Frequently asked questions

What time will I get my keys?

You get your keys once the money has reached the seller’s solicitor and they have confirmed it to the estate agent. Many completions happen around midday to early afternoon, but in a chain the money moves one link at a time, so it can be later. We tell you as soon as completion has taken place. If you are booking removals, plan for the possibility of an afternoon key collection.

Can I move in before completion?

Usually not. Until completion the property still belongs to the seller, and moving in early would need the seller’s agreement and, if you have a mortgage, your lender’s. It can also affect your legal position. If you have a particular reason for needing early access, talk to your conveyancer and we will explain what is possible.

Why haven’t my keys been released yet?

The most common reason is that the money is still moving through the chain. The seller’s solicitor can only confirm completion once the money has arrived, and the agent can only release the keys after that. We will tell you where things stand. Please do not collect keys or enter the property until we or the agent confirm completion has taken place.

What happens if the money is late?

If money is held up at a bank, a lender or elsewhere in the chain, completion may happen later in the day or, occasionally, on a later day. We track the money and keep you informed. The consequences of a late completion depend on the contract, and we will explain the position on your own matter.

Do I need to be at your office on completion day?

No. Completion happens between the solicitors by bank transfer, so you do not need to be at our office. Keep your phone to hand so we can reach you, and we will tell you when completion has taken place.

What if the seller hasn’t moved out?

The contract normally requires the seller to leave the property empty by the agreed time on completion day. If they have not, tell the estate agent and call your conveyancer straight away, and do not try to resolve it yourself on the doorstep. We will explain your position and contact the seller’s solicitor.

When is my Stamp Duty paid?

If you are buying, we usually collect the Stamp Duty Land Tax with your completion money, then pay it to HMRC and file the return after completion. The legal deadline is 14 days after completion. The amount depends on the price and your circumstances; GOV.UK’s calculator gives an estimate, and we confirm the figure for your purchase.

When will I be registered as the owner?

We apply to HM Land Registry soon after completion. How long registration takes depends on HM Land Registry’s workload and can range from weeks to many months; it publishes its current processing times. The wait does not affect your right to live in the property, which begins at completion. We send you a copy of the updated title when registration is complete.
