Completion day is the day it all becomes real: the money changes hands, the property legally becomes yours, and you finally get the keys. After months of process it can feel strangely anticlimactic — or surprisingly tense. Here’s exactly what happens and how to be ready.
What completion day actually is
Completion is the moment ownership transfers from the seller to the buyer. It happens after exchange of contracts, which is when the sale became legally binding and the completion date was fixed.
On the day itself, the outstanding purchase money is transferred, the legal title passes to you, and the keys are released. From that point, the home is yours.
The week before
The groundwork is done in the days leading up to completion, not on the day:
- Sign everything. Your conveyancer will have you sign the transfer deed and mortgage deed in advance.
- Get your funds in place. Your deposit and any other money you’re contributing need to be cleared in your solicitor’s account before the day — bank transfers can take time, so don’t leave it to the last minute.
- Confirm the mortgage. Your conveyancer requests the mortgage funds from your lender so they arrive in time.
- Book removals and take meter readings. Arrange your move, redirect your post, and note final gas, electricity and water readings.
What happens on the day
It’s mostly out of your hands and in your solicitor’s:
- Your solicitor sends the balance of the purchase price to the seller’s solicitor.
- The seller’s solicitor confirms the money has arrived.
- Completion is “called” — the sale is done.
- The seller’s solicitor authorises the estate agent to release the keys.
Timings vary. Money often moves in the morning, but in a property chain everyone has to complete in sequence, so keys are frequently not ready until the early afternoon. There’s no fixed time — it depends on when the funds clear down the chain.
What if something goes wrong
It’s rare after exchange, but delays happen — usually funds not arriving in time, or a holdup somewhere in the chain. If completion doesn’t happen on the agreed day, the party at fault may have to pay interest or other costs, and in serious cases a “notice to complete” can be served, giving a short deadline to finish. Because you’re already legally committed from exchange, a wobble on completion day is about timing, not the deal collapsing.
After completion
A couple of important things happen once you have the keys:
- Stamp duty. Your conveyancer files your Stamp Duty Land Tax return and pays it on your behalf, within the deadline after completion.
- Land Registry. They register you as the new legal owner. This can take a while to process, but you’re the owner from completion regardless.
- Keep your documents. Store the completion statement, title information and any guarantees safely — you’ll want them when you eventually sell.
The bottom line
Completion day is the payoff, and by the time it arrives most of the hard work is behind you. Get your funds and paperwork sorted in the days before, be patient on the day itself — especially in a chain — and have a backup plan for collecting the keys if it runs late. Then go and enjoy your new home.
Common questions
What time do you get the keys on completion day?
There's no fixed time. Funds often move in the morning, but in a chain everyone must complete in sequence, so keys are commonly released in the early afternoon once the money has cleared all the way through. Your agent releases them as soon as the seller's solicitor confirms receipt.
What happens if completion is delayed?
Delays are usually down to funds not arriving in time or a holdup elsewhere in the chain. The party at fault may owe interest or costs, and a 'notice to complete' can set a short deadline to finish. Because you're committed from exchange, it's a question of timing, not the sale falling through.
What do you need to do after completion?
Your conveyancer files and pays your Stamp Duty Land Tax and registers you as the owner at the Land Registry. You should redirect your post, set up utilities and council tax, and store your completion documents safely for when you eventually sell.
