What Happens on Completion Day?

3 min read · Last reviewed 1 June 2026

In brief

  • Completion day is when the balance transfers from your solicitor to the seller's solicitor
  • Keys are released by the estate agent once funds are confirmed — typically by midday
  • Your solicitor handles everything on the day — your job is to be ready to move
  • Delays are rare but happen: be flexible with your removal team's start time
  • After completion: register utilities, contact council tax, redirect post

Completion day is the day you become a homeowner. After months of viewings, offers, surveys, and solicitor letters — this is the day the money moves and the keys come out.

Here's exactly what happens.

The night before completion

Your solicitor sends you a completion statement — a detailed breakdown of every figure involved in the transaction:

  • The purchase price
  • Minus your mortgage (which your lender sends directly)
  • Minus your deposit (already paid on exchange)
  • Plus any adjustments (council tax apportionment if the seller has prepaid, ground rent adjustments on leasehold)
  • Plus your solicitor's fees and disbursements
  • = The amount you need to transfer to your solicitor

You transfer this balance to your solicitor's client account the night before or early on completion day. Most solicitors ask for it by 9am. This is a large CHAPS transfer — check the bank transfer limits on your online banking and call your bank if you need to arrange it.

Completion morning: what your solicitor does

8–9am: Your solicitor confirms they've received your balance (and that the mortgage funds have arrived from your lender, if applicable).

9–11am: Your solicitor prepares the CHAPS transfer for the completion funds — the full purchase price. This is usually the sum of: your deposit (already with your solicitor from exchange), your balance, and your mortgage advance.

~10–11am: Your solicitor sends the CHAPS transfer to the seller's solicitor.

~11am–12pm: The seller's solicitor confirms receipt of funds to the estate agent. The estate agent notifies you and releases the keys.

When you collect the keys

Estate agents usually hold the keys until the seller's solicitor calls to authorise release. This call happens once the transfer is confirmed received — typically between 11am and 1pm on a normal completion day.

You (or your removal team) go to the estate agent's office to collect the keys. Bring ID — most agents will check. Some agents have digital key-safes or arrange handover directly from the seller.

Once you have the keys, the property is yours.

If there's a chain

In a chain — where your seller is buying somewhere else, and so on — completions all happen on the same day. The money moves sequentially through the chain: from the first buyer's solicitor, to the next, to the next, until it reaches the last seller.

This means you're waiting for everyone else to complete before you can complete. It's why completions in a chain can take until 2pm or 3pm, even when everything goes smoothly.

What to do on completion day

Before keys: Arrange your removal team to load up from your current home in the morning. Don't book them to arrive at your new home until you have the keys — staging the timing saves standing around on a lorry.

Once you have keys: Take meter readings immediately. Gas, electricity, water. Photograph them. Contact the utility suppliers to register as the new occupant.

First evening: Make sure buildings insurance is active from this day (it should have been arranged from exchange). Change the locks — you don't know how many previous key copies are in circulation.

Within 7 days: Contact the council to register for council tax from completion day. Set up a mail redirection with Royal Mail. Update your address with your bank, employer, DVLA, HMRC, and any subscriptions.

Frequently asked questions

Most completions happen between 11am and 1pm. Your solicitor transfers the completion funds in the morning, and the estate agent releases keys once the seller's solicitor confirms receipt. You can usually expect to collect keys by midday, but some completions run into early afternoon.

Delays can happen — bank processing issues, last-minute queries on the completion statement. Your solicitor will chase. In most cases, a delay of an hour or two is resolved without consequence. If the delay runs into the next day, your solicitor will invoke the contract's late completion clauses, which protect you.

Yes — and most buyers do. The practical reality is that your removal van arrives at your old home in the morning, loads up, and arrives at your new home once you have the keys. This is why midday-ish key release can feel tight if you have a full house to move.

If you're a first-time buyer, you have no existing mortgage to deal with. Your new mortgage drawdown happens automatically through your solicitor on completion day. If you're a home mover, your solicitor will request a redemption figure from your current lender and repay that mortgage simultaneously.

Your solicitor will send you the completion statement showing all figures, and confirmation that completion has occurred. The title register at HMLR won't show your name immediately — registration takes 2–8 weeks — but your solicitor will send you official copies once it's done.
