What happens on the day
1. Funds are sent
Your solicitor transfers the balance (mortgage funds plus your deposit) to the seller's solicitor by CHAPS or faster payment.
2. Receipt is confirmed
The seller's solicitor confirms the full purchase money has arrived in their account.
3. Completion is declared
The transaction legally completes and ownership passes to you.
4. Keys released
The estate agent is authorised to release the keys, often around midday or early afternoon.
5. Post-completion
Your solicitor pays stamp duty, registers you with the Land Registry and sends your mortgage lender the paperwork.
A typical completion-day timeline
Exact timings vary, but most completions follow a similar shape.
| Time | What usually happens |
|---|---|
| Early morning | Your solicitor releases funds up the chain |
| Late morning | Money moves between solicitors as each link completes |
| Midday to early afternoon | Seller's solicitor confirms receipt; keys released |
| Afternoon | You collect keys and begin moving in |
| After the day | Solicitor handles stamp duty and registration |
In a long chain, every link must complete before yours can, which is why an early slot helps.
Exchange vs completion
| Exchange of contracts | Completion | |
|---|---|---|
| What it does | Makes the sale legally binding | Transfers ownership and keys |
| Deposit | Usually paid at this point | Balance paid now |
| Can you pull out? | Only by forfeiting deposit | No, it is done |
| Date set | Completion date fixed here | The agreed date arrives |
How to prepare for completion day
A little planning avoids a frantic day.
- Book removals provisionally before exchange, then confirm once the date is fixed.
- Arrange buildings insurance to start from exchange, not completion.
- Take final meter readings and notify utilities, council tax and your bank of the move.
- Have a 'first night box' with essentials, you may get keys later than hoped.
- Keep your phone on, your solicitor and removals firm may need to reach you.
Avoid Friday and a late slot
Completing early in the day and avoiding Fridays reduces the chance of money getting stuck in a chain and delaying your keys. Friday is the busiest day for completions, so payment systems can be slower.
What can delay completion, and what happens if it does
The most common cause of delay is money moving slowly through a chain. Because each purchase often funds the next, a hold-up at one link delays everyone above it. Bank processing times, late mortgage draw-downs and missing paperwork can all play a part.
If completion fails to happen on the agreed date, the contract usually allows a short grace period before penalty interest applies, and in serious cases a 'notice to complete' can be served, typically giving ten working days to finish or risk losing the deposit. These situations are rare, but they are why solicitors push to complete early in the day.
