What happens on completion day when selling a house?

Published 23 June 2026 · 5 min read · By Evren Ergin

Completion day is the day the sale legally finishes: the buyer's money reaches your solicitor, ownership transfers, and you hand over the keys. For the seller it usually means being moved out and giving vacant possession by an agreed time, often early afternoon, once your solicitor confirms the funds have landed.

TL;DR

  • Completion is the final step of a sale, when the money changes hands and ownership legally transfers to the buyer.
  • It comes after exchange of contracts, and the gap between exchange and completion is typically 7 to 28 days.
  • Keys are released only after your solicitor confirms the full balance has arrived, so the money always moves before the keys.
  • As the seller you must be moved out and give vacant possession, usually by an agreed time such as 1pm.

Exchange of contracts is the moment a sale becomes legally binding, when neither side can pull out without penalty. Completion is the later day when the rest of the money is paid and ownership of the home passes to the buyer.

What is the difference between exchange and completion?

They are two separate milestones, often a week or two apart. Exchange locks the deal in; completion is the day the deal actually happens.

Exchange versus completion

StageWhat happens
Exchange of contractsThe sale becomes legally binding, the buyer pays a deposit (usually 10%), and a completion date is fixed.
CompletionThe buyer pays the balance, ownership transfers, your mortgage is repaid, and the keys are released.

How long is it between exchange and completion?

The gap is agreed between buyer and seller and is typically 7 to 28 days, though it can be as little as the same day. The time is often used to arrange removals, transfer money up and down the chain, and give everyone a fixed date to plan around.

What happens on completion day, step by step?

  1. 1. Funds arrive with your solicitor

    The buyer's solicitor transfers the balance of the purchase price to your solicitor on the morning of completion.

  2. 2. Your solicitor confirms the money

    Once the funds have cleared, your solicitor completes the legal transfer of ownership to the buyer.

  3. 3. Your mortgage is repaid

    Your solicitor uses the proceeds to pay off any outstanding mortgage on the property.

  4. 4. Keys are released

    Your solicitor authorises the estate agent to hand the keys to the buyer.

  5. 5. You give vacant possession

    You must be moved out and have left the home empty and clean by the agreed time, often 1pm.

  6. 6. You receive your proceeds

    Your solicitor sends you the net sale proceeds after fees and any mortgage payoff, usually the same or next working day.

When do I get my money on completion day?

You receive the net proceeds, which is the sale price minus your remaining mortgage, the estate agent's fee and conveyancing costs. The money normally reaches your account on completion day or the next working day, depending on when the funds clear.

When do I hand over the keys?

Keys are the last part of the sale to move, and only after your solicitor confirms the money has landed. In practice you leave the keys with your estate agent, who passes them to the buyer once given the go-ahead. Vacant possession means the home is empty of people and belongings, except anything agreed to stay, and is reasonably clean.

What can go wrong on completion day?

Most completions are smooth, but a few snags are worth planning around.

  • Bank transfers arriving late, which can push the key handover into the afternoon.
  • A delay further up or down the chain holding up everyone's completion.
  • Items left behind, which can breach vacant possession and cause a dispute.
  • Removals overrunning, so it helps to be packed and ready the night before.

Can completion and exchange happen on the same day?

Yes. A simultaneous exchange and completion is common on simple sales and is faster, but it carries more risk because nothing is certain until the day itself.

What time do I have to be out by?

By the time set in the contract, which is often 1pm but can vary. Confirm the exact deadline with your solicitor and plan your removals around it.

Do I need to be there on completion day?

No. Your solicitor handles the money and legal transfer, and the estate agent handles the keys. You just need to be moved out and to have dropped off the keys as agreed.

What is vacant possession?

Vacant possession means handing the home over empty of people and belongings, apart from any fixtures or items agreed to stay, and in a reasonably clean state so the buyer can move straight in.

Completion day rewards preparation. Be packed early, leave the home as you would want to find it, and let your solicitor confirm the money before you let go of the keys.
